Emphasizing principally the function to cook, which turns out to be exhausting due to the bothersome process that implies carrying out it. The process comprises the transfer to the place of buy, the search of the inputs, the selection of the inputs, the long tails to pay, the wash of the inputs as well as stung of the same ones, between others. Therefore, an alternative solution to this problem is proposed, which consists of the delivery through the online sale of boxes with fresh uncooked inputs chopped and the exact quantities of various Creole dishes. This paper seeks to determine the financial viability of the project in question in order to validate the possibility of implementing it in a real-world scenario.

Full textWhile more Canadians discussed the nuclear threat in these years the majority did not join the debate. Polls showed the public supported a nuclear defence. They believed few would survive a nuclear attack but did not worry about nuclear war. Economic concerns always ranked higher. The public was, on the whole, not mobilized either in preparation or in protest. Diefenbaker questioned what else he could do to increase public concern about survival. Both the civil defence program and the nuclear disarmament movement struggled. Polls showed that most Canadians did nothing to prepare for a war fought at home. Anti-nuclear groups remained small, divided over their platforms and methods and faced financial constraints. The debate about survival grew in the period between 1957 and 1963 but was dominated by elected officials, civil defence authorities and anti-nuclear activists. Even these groups found it difficult to balance the Soviet threat with the risk of a nuclear war and struggled to achieve policies that would provide security for the nation and its population.

Full textPlanetary systems are born in circumstellar gas and dust disks surrounding Young Stellar Objects (YSOs). To understand how planetary systems form, a detailed knowledge of the structure and evolution of these disks is required. Although, this is almost well understood for the regions of the disks observed with a spatial resolution of several AUs, the structure of these disks probed at a few AU scale and especially inward of 1 AU remains a puzzle. In recent years, it has become possible to directly spatially resolve the inner region of protoplanetary disks with optical interferometry technique. The context of this thesis is a multi-wavelength investigation of the protoplanetary disks evolution by determining their density distribution, their temperature distribution, the size and com- position of the dust components and finally the kinematics of the gas. I have developed my thesis following three complementary wavelength domains: study of the photosphere of the star and its nearby gaseous disk through visible interferometry, study of the radial and vertical structure of the inner rim of a pre-transitional disk at fractions of an AU through near-IR interferometry, and, the characterization of the disk regions at a few AUs from the central star through spectroscopic and mid-IR interferometry. To analyse the visible-, near- and mid-IR interferometric observations, I have focused my attention on three well known sources, 51 OPh, HD 100546 and MWC 480 respectively that they have not been observed in these wavelengths

Full textIntroduction: Laboratories in Human Reproduction, quality control is crucial to the success of procedures. The correct implementation of procedures directly influence the results, especially because the vagina, the follicular fluid and semen can not be sterilized. A high degree of hygiene, cleanliness and disposal of the material must be observed to avoid contamination in the culture media and equipment. The main causes of this contamination has been associated with infection in male and female genital tract and subsequent contamination of oocytes and embryos of patients. Can also come from contamination of air, machinery and materials such as culture dishes. Objectives: of this study were the presence of market info bacteriological contamination and mycological culture dishes of human embryos and to identify the genus level. Methodology: 125 samples were collected from culture dishes human embryos after transfer to the uterus, in three laboratories of human reproduction in the city of Goiania-GO, in the period 2009 to first half of 2010. The culture media were inoculated in BHI broth and incubated in the greenhouse. Samples that clouded (positivist) were isolated and identified. Results: showed a prevalence of 4.8% of contamination and micro-organisms found were Escherichia coli (50%), Klebsiella sp (16.6%), Pseudomonas sp (16.6%), yeast (16.6%). The E. coli bacteria were of the highest incidence was found in three samples. Although the culture media provide the antibiotics penicillin G (IVF) or gentamicin (HTF), resistant Gram-negative rods were found. Conclusion: Results with a prevalence of 4.8% of contamination, and the microorganisms isolated and their amount per sample: Escherichia coli (3), Klebsiella sp (1), Pseudomonas sp (1), yeast (1).
Introdução: Em laboratórios de Reprodução Humana, o controle de qualidade é de fundamental importância para o sucesso dos procedimentos. A realização correta dos procedimentos influem diretamente nos resultados, principalmente porque a vagina, o líquido folicular e o sêmen não podem ser esterilizados. Um alto grau de higiene, limpeza e o descarte do material devem ser observados para se evitar contaminação nos meios de cultura e equipamentos. As principais causas desta contaminação vem sendo associadas à microbiota e infecção oportunista no trato genital masculino e feminino e consequente contaminação dos ovócitos e embriões dos pacientes. Também pode vir da contaminação do ar, de maquinários e materiais utilizados, como as placas de cultivo.

Full textThe study of the transition between proto-planetary gas-rich disks and debris disks, where gas has disappeared in a few millions years, is crucial to constrain the planet formation mechanisms. More ans more gas-rich debris disks are detected. I have studied some of those disks where observations suggest that gas is still primordial. Thanks to radio interferometers suche as ALMA and NOEMA, i have observed in details the debris disk around the ten millions year okd HD 141569 star, of spectral type A0V. My observations reveal the gas disk is primordial and is dissipating, which makes the disk a hybrid system. The milimeter dust has also evolved, since its emission is weak and has e spectral index beta typical of large grains. To detect more hybrid disks, i have observed th CO gas in 25 disks with APEX and the IRAM 30 m. Around HD 23642, CO emission is detected at 4 sigma and coukd correspond to a peculiar disk, since it surrounds binary stars in the Pleiades cluster, which age is estimate around 125-130 millions years. The emission of the gas and dust is correlated for all types of disks but hybrids, where the high flux ratio might be due to a rapid dust evolution. It remains to know whether this phase is common to all disks to understand the implications of this phenomenon

Full textThe ancient agglomeration of Grand has been the subject of increased research for more than half a century. Archaeologists have alternately invested new excavation areas with the objective of revealing the nature and status of this site, famous for its extraordinary discoveries. During the field operations, the duly collected ceramic pots and potsherds filled the reserves, the warehouses and the museum display case. Although ceramic has given rise to a description, no general study has presented on its evolution over time and on the scale of the site. This thesis wants to answer to theses questions by providing an indispensable typological tool for all future archaeological operations. The Grand ceramic facies established for the first four centuries of our era enrichies many research axes both on the scale of the site and that of the territory of the Leuci to which it belongs

Full textThe relevance of the work. The importance of researching the principles, methods, and strategies for translating the names of Chinese dishes into Russian in recent years has attracted the attention of an increasing number of scientists and specialized academic institutions in connection with the globalization of the world economy. This type of cultural communication activity involves not only the transformation of linguistic symbols but also the integration of cultures. While language is part of the culture, the overseas development, and growth of China's foodservice industry is an important part of global economic activity. The Russian translation of the names of Chinese dishes is no longer a purely literary translation of the text. In a sense, this should be external communication activity or even a full-fledged foreign economic activity. The quality of the Russian translation of the names of Chinese dishes in many ways directly affects the scale and effectiveness of the development of the Chinese catering industry in Russia. However, due to cultural differences and other reasons, there are many difficulties in translating the names of Chinese dishes into Russian. This requires the use of the necessary techniques for translating the names of Chinese dishes into Russian so that the translated names fully reflect the regional and national characteristics of Chinese cuisine. Based on the research of Chinese translator Bao Huinan and British translator Taylor on the translation of dish names, this article summarizes the problems of the translation of Chinese dish names into Russian. The author of this article attempts to find a solution to the problems encountered in translating Chinese dish names into Russian on a theoretical basis. According to translators Carl and Taylor, finding a suitable translation method according to different translation situations is the best strategy. Regarding the cultural differences encountered in translating Chinese dish names into Russian, it is recommended that translators consider and study these two strategies dialectically, historically rather than statically and absolutely. According to the above-mentioned principles, we propose to solve the problem of translation of Chinese dish names into Russian and methods to translate dish names.

Full textThe stars, during the first millions years of their existence, are surrounded by a protoplanetary disk composed of99 % of gas and of 1 % of dust. The dust is initially under the form of sub-micrometric grains but evolves to likelyform planets. Thanks to the Plateau de Bure interferometer, with whom we observed at the millimeter wavelengths, the temporal evolution as well the radial distribution of the dust grains has been bringing to light in several disks.In addition, the important gain in resolution and in sensibility of ALMA, a new interferometer based in Chili, has required the improvement of our transfert radiativ code in order to determine if and how it will be possible to observe the dust settling, preliminary step for the formation of planetesimals

Full textThe diversity observed in the exoplanet population likely originates in the variety of physical structures of protoplanetary disks, their progenitors. Considering the timescales for disk dissipation, it is clear that giant planets must form fast, within a few million years. In the standard core accretion model, this implies that micron sized particles have to grow within this short timescale to larger sizes. This PhD thesis is dedicated to adding observational constraints on several aspects of protoplanetary disk evolution in order to understand better the processes of planet formation. In particular, I worked on a statistical study of the dust mass distribution in protoplanetary disks located in the Chamaeleon II star-forming region, on the presence of dust depleted cavities in transition disks and on observational constraints on dust evolution mechanisms such as radial drift and vertical settling. I used mostly ALMA millimeter observations, which I combined with complementary disk tracers such as optical/infrared scattered light images. On several occasions, I modeled these observations with radiative transfer to constrain the structure of these protoplanetary disks.During this thesis, I have obtained important constraints on the vertical structure of protoplanetary disks, notably by studying a sample of 12 highly inclined disks. I find that the most inclined systems of this survey, where the vertical extent is best seen, are extremely thin at millimeter wavelengths, all the more when compared to their vertical extent seen with scattered light observations (probing smaller grains). This indicates that vertical settling is extremely efficient in these disks, which is favorable for fast grain growth in the disk midplane. Additionally, my study of the Chamaeleon~II star-forming region showed that the distribution of the disk dust mass statistically decreases with time. This is consistent with predictions from viscous evolution. Finally, with the study of a sample of 22 transition disks, I showed that their cavities can mostly be explained by the presence of planets. These results suggest that planets might already have formed in these disks, implying that the timescale available for planet formation is short. A possible mechanism allowing to boost planet formation is vertical settling. Indeed, as detailed previously, my studies showed that the vertical extent of protoplanetary disks is small at millimeter wavelengths, which implies that millimeter sized grains (and larger) are concentrated in a vertically thin midplane where the dust density is increased. Depending on when this vertical settling takes place, this mechanism is a good candidate for enhancing grain growth efficiency. Combined to other processes, vertical settling might allow to form planets in the earliest stages of disk evolution

Full textDwarf novæ have been used for almost 50 years now as a test for the theory of accretion. These systems exhibit eruptions in optical light lasting approximately a week with a recurrence time scale of a month. Eruptions are thought to be due to a thermal-viscous instability in the accretion disk surrounding the white dwarf. This model has long been known to put constraints on the mechanisms transporting angular momentum in the disk, which will be the subject of this thesis. Traditionally, transport is presumed to be turbulent where turbulence is due to the magneto-rotational instability (MRI). However, I show here, using local simulations of accretion disks with radiative transfer that there exists a discrepancy between observations and light curves obtained with MRI turbulence only. In quiescence, where the disk is poorly ionised, it is very unlikely that MRI can even survive. One of the key results of this thesis is that MRI do not participate to turbulent angular momentum transport only, but is also able to drive MHD outflows which extract angular momentum very efficiently, especially in quiescence. Wind-driven transport is, by nature, very different from turbulent transport, it induces a surface-torque on the disk and do not deposit thermal energy locally but extract energy from the disk instead. We included MHD wind-driven angular momentum transport in a disk instability model, model which is usually used to reproduce light curves of dwarf novæ. Using this new model, we were able to retrieve light curves looking alike observations, with a magnetic field consistent with what is expected from the dipolar magnetic field of a white dwarf. It is the first time that eruptions of dwarf novæ are modeled with success using prescriptions for angular momentum transport derived from first principles instead of ad hoc parameters

Full textThe vertical magnetic field plays a fundamental role in the dynamics of accretion discs. The jet launching, so as the turbulence that is supposed to exist in these discs are strongly constrained by the intensity of this field. This field evolves following the mechanisms of advection by the mater and diffusion by turbulence. The question of the evolution of such a field has been studied since more than 20 years, but a global modelisation, involving all these méchanisms wasn't done yet. I propose a model, taking into account the transport of a vertical magnetic field by the disc, and also the feedback of this field on the dynamics of the disc. Analytical solutions for standard configurations a calculated. It confirms previous studies in the sense that considering the state of the art, a turbulent disc can not advect a vertical field in order to allow a jet launching. However, a new configuration is rised, in wich the ejection conditions are realised in the outer radius of the disc. The stability of the standard configurations is calculated, and new instabilities are rised. The effectivity of such instabilities depends on the functionnal dependancies used to quantify the disc dynamics. A determination of such dependancies, via local simulations, would clarify if such instabilities could be effective in accretion discs. At last, the numerical tools developped allows to study the configurations. Standard one are found, and a dynamical study of the new configuration is done to determine the advection conditions for the limit ejecting disc/ standard disc

Full textAt least 20% of Main-Sequence stars are known to harbor debris disks analogs to the Kuiper Belt. These disks are proof that the accretion of solids has permitted the formation of at least km-sized bodies. It is thus not surprising that several of these disks are accompanied by planets, which may reveal themselves by setting their dynamical imprints on the spatial structure of debris disks. Therefore, the detection of an eccentric debris disk surrounding Zeta² Ret by the Herschel space telescope provides evidence for the presence of a massive perturber in this system.Zeta² Ret being a mature Gyr-old system, and in that sense, analogous to our own Solar System, it offers a different example of long-term dynamical evolution. This thesis includes a detailed modeling of the structure of the debris disk of Zeta² Ret, which leads to constraints on the mass and orbital characteristics of the putative perturber. This study also reveals that eccentric structures in debris disks can survive on Gyr timescales.Detailed modeling of the structure of debris disks can allow the posterior discovery of hidden planets as is the case for the Fomalhaut system. The eccentric shape of the debris disk observed around this star was first attributed to Fom b, a companion detected near the belt inner-edge, which revealed to be highly eccentric (e~0.6-0.9), and thus very unlikely shaping the belt. This hints at the presence of another massive body in this system, Fom c, which drives the debris disk shape. The resulting planetary system is highly unstable, which involves a recent scattering of Fom b on its current orbit, potentially with the yet undetected Fom c. This scenario is investigated in this thesis and its study reveals that by having resided in inner mean-motion resonance with a Neptune or Saturn-mass belt-shaping eccentric Fom c and therefore have suffered a gradual resonant eccentricity increase on timescales comparable to the age of the system (~440 Myr), Fom b could have been brought close enough to Fom c and suffered a recent scattering event, which, complemented by a secular evolution with Fom c, explains its current orbital configuration. This three-step scenario also implies that significant amounts of material may have been set on extremely eccentric orbits such as this of Fom b through this mechanism, which in return could feed in dust the inner parts of the system. Therefore, this mechanism may also explain the presence of inner dust belts in the Fomalhaut system, but also the discovery a significant population of very bright hot dust belts in systems older than 100 Myr.The planetary systems discovered so far exhibit a great variety of architectures, and our solar system is far from being a generic model. One of the main mechanism that determines a planetary system morphology is planetary migration. The presence of a stellar binary companion - which our solar system is deprived of - is expected to affect planetary migration conditions, and potentially lead to the formation of very different planetary systems. This phenomenon is obviously non-negligible since binary systems represent at least half of stellar systems. At late stages of planetary systems formation, planetary migration may occur as the result of interactions with remaining solid planetesimals and the impact of binarity on this planetesimal-driven migration is explored in this thesis. A stellar binary companion may in fact reverse the tendency for planets in single star systems to migrate inwards, and bring them closer to regions perturbed by the binary companion, where they could not have formed in situ. This may give an explanation for the presence of planets which present signs of outward migration towards a circumstellar companion in the Gamma Cephei and HD 196885 systems

Full textBe stars are recognized by their rapid rotation and non-radial pulsation. They are the only stars in the Main Sequence that have circumstellar disks that are formed by processes not yet fully understood. The modeling of the forces acting on this system leads to theoretical predictions about the structure of the disk that can be compared to observational data. We can study physical the properties of Be disks by modeling how stellar light is reprocessed by them. This requires solving the detailed radiative transfer problem involved. In this point, the study of polarization arise as a useful tool to investigate these disks, allowing for the determination of important physical quantities of the system, such as the particle number density and inclination angle. An intriguing variability observed in Be stars is the aperiodic transition between a B normal phase (without disk) to a Be phase (with disk). Recent monitoring studies found, from the analysis of the intrinsic polarization arising of the transition between these phases, a significant relation between the polarization change through the Balmer jump versus the V-Band polarization, giving rise to a loop structure as a function of time, in the so-called Color-Polarization Diagram. This work presents an analysis of the Color-Polarization Diagram by several models. We make use of the Viscous Decretion Disk Model, which assumes the existence of some injection mechanism of material at keplerian velocities in the disk base, where the turbulent viscosity acts carrying angular momentum from de inner parts to the outer regions. With this, we aimed to extend our knowledge about the fundamental mechanisms involved in the formation and dissipation processes of the disk.

Full textPlanetary formation occurs in the protoplanetary disks of gas and dust. Although dust represents only 1% of the total disk mass, it plays a fundamental role in disk chemical evolution since it acts as a catalyst for the formation of molecules. Understanding this chemistry is therefore essential to determine the initial conditions from which planets form.During my thesis, I studied grain-surface chemistry and its impact on the chemical evolution of molecular cloud, initial condition for disk formation, and protoplanetary disk. Thanks to numerical simulations, using the gas-grain code Nautilus, I showed the importance of diffusion reactions and gas-grain interactions for the abundances of gas-phase species. Model results combined with observations also showed the effects of the physical structure (in temperature, density, AV) on the molecular distribution in disks

Full textRecent spatially resolved observations of protoplanetary disks have revealed the presence of structures with complex morphologies, indicating the probable presence of protoplanets inside. How could the grains in the disc have formed these structures? How will they evolve? To answer these questions, we need to understand how grains grow inside the disc. However, numerical resolution of the coagulation equation by traditional methods requires prohibitive sampling, making it impossible to integrate it into a three-dimensional hydrodynamic code.The goal of this thesis is the development of an algorithm to solve the coagulation equation while respecting the constraints guided by astrophysics: rigorous conservation of mass while keeping a precision lower than the hydrodynamic errors on a mass spectrum relevant to the observations. Sampling must be minimal to allow coupling with a hydrodynamic code. To do so, the coagulation equation is solved by an original numerical scheme based on the discontinuous Galerkin method and a high order integration. The efficiency of the method is demonstrated on the known solutions of the equation and transferred to the context of planet formation.Work carried out in parallel with this study will be presented. Firstly, an analysis of extra-solar planet observations made with the SPHERE/VLT instrument. Secondly, the numerical resolution of stochastic equations to understand grain sedimentation in turbulent disks

Full textThe objective of this thesis is to study the formation of vortices in the dead-zone of protoplanetary disks. A 3D compressible numerical code has been performed and used for this study. Two hydrodynamical instabilities are considered for vortex formation: the Rossby wave instability and the baroclinic instability.The first one leads tp the fragmentation of an annular bump into a chain of vortices that catch one another and merge in a single vortex; this vortex remains stable on very long durations when its aspect ratio is large enough and has a quasi two-dimensional structure. In contrast, tridimensional small aspect ratios vortices are affected by the elliptical instability and are destroyed in a few rotation periods. Only vortices with large aspect ratios can survive.The baroclinic instability, a basically non-linear one, can produce vortices from small amplitude perturbations; these vortices are then amplified and merge in bigger vortices if the disk is unstably stratified and also permits heat transfer. Two types of heat transfer have been considered leading to significant differences in the structures of the resulting vortices. As aspect ratio and vorticity are strongly related, the baroclinic amplification reduces the aspect ratio and, so, make the vortex sensitive to the elliptical instability. However, such vortices are not destroyed and keep a vertical structure thanks to the baroclinic amplification

Full textTo this day, thousands of planets have been identified outside of our own solar system. Theirformation is thus not an unlikely occurence. A number of still-forming young stars are also known,circled by remnants of gas and dust which are shaped by centrifugal forces into disk-like objects. Inthose disks, planets are born as they accumulate nearby material. Although the successive steps of thisevolution, from micrometric grains to planet-sized objects are relatively well identified, the remainingchallenges are numerous. Indeed, small size solids tend to rapidly accrete (in a few million years) ontothe star. It is also the case (albeit for different reasons) of planet-mass objects, which concede theirangular momentum to the circumstellar disk. In this thesis, I study possible solutions to such problemsthrough hydrodynamical simulations. I show that, contrary to a received idea, migration of giantplanets does not follow the viscous spreading in the disk. Moreover, I highlight that planetary accretiondoes not significantly affect migration rates. Then, I deal with a scenario that favours constructiveagregation of dust, namely Rossby vortices, whose existence is still debated for we lack observationalconstraints. I show that such structures could be identified through a handful of observables, amongwhich dynamical signatures seen in Doppler shifts. Using radiative transfer as a post-processing meth-od,I provide additional predictions for signatures in interferometric observations of thermal emission, aswell as polarimetric features of those vortices. Finally, I dedicate my last chapter to describing my maincontributions to open source projects that I used throughout my thesis

Resumo: Soluções exatas das equações do campo de Einstein que representam espaços-tempo com distribuições de matéria em forma de discos são construídas pelo método inverso (método das imagens). Estas soluções incluem discos estáticos ínos de fluido perfeito com e sem halos, discos estáticos finos de fluido perfeito com carga elétrica e modelos de discos finos formados por poeira carregada. São estudadas ainda novas soluções em vários sistemas de coordenadas que representam discos estáticos grossos com espessura constante. Uma forma particular para a métrica isotrópica em coordenadas cilíndricas é usada para obter-se versões relativísticas de pares potencial-densidade Newtonianos comumente usados na Astronomia Galáctica. Um modelo relativístico simplificado, porém exato, de um núcleo ativo de galáxia também é apresentado. Finalmente, é feito um estudo de alguns pares-potencial densidade Newtonianos obtidos a partir da expansão multipolar do potencial Newtoniano que generalizam pares conhecidos
Abstract: Exact solutions of Einstein field equations that represent space-times with disklike matter distributions are constructed using the inverse method (image method). These solutions include static thin perfect uid disks with and without halos, static thin charged perfect uid disks and models of thin charged dust disks. New solutions in various coordinate systems that represent static thick disks with constant thickness are also studied. A particular form of the isotropic metric in cylindrical coordinates is employed to obtain relativistic versions of Newtonian potential-density pairs commonly used in Galactic Astronomy. A simplified, although exact, relativistic model of an active galactic nuclei is also presented. Finally, some Newtonian potential-density pairs obtained from the Newtonian multipolar expansion that generalize known pairs are studied.

Full textIn this thesis, we have been interested on the effects of the magnetic cavity and the stellar tides in synthetic planet population. The magnetic cavity is thought be important at the formation phase since it can truncates the gaseous disk and potentially stops the inward migration of planets (Lin et al. 1995). In this work we modified the standard radial viscous equation in order to take into account the effect of the magnetic torque on the gaseous disk (Armitage et al. 1999). Moreover, the stellar tides have been included in an analytical way as in (Bénitez-Llambay et al. 2011). For this work, we used the planetary model of Bern (Mordasini et al. 2012) at which we included both effects. The end of the thesis compare the synthetic orbital distribution with the orbital distribution observed by Kepler (Howard et al. 2012).Finally, a last chapter treats a topic different than the rest of the thesis. We tested the so called pebble mechanism (Ormel&Klahr2010) in the planetary formation model of Bern. So far, this chapter is a first step to a more complete model. However, we show that the numerical implementation is working well

Full textThe role of anticyclonic vortices in the protoplanetary disk evolution and in how do planetesimals form are among the most important chalenges of the modern astrophysics. That is why an exhaustive study of the structure and the evolution of these vortices is necessary.Thanks to a numerical code specificly designed for the study of these disks, we have revisited the Rossby Wave Instability in the nonlinear regime, and have discovered that a cascade of the perturbation modes can explain the formation of the vortices created by this instability.We have described the structure of these Rossby vortices with a new gaussian vortex model, which accurately fits the numerical results. A sample of 300 different vortices led us to define the bondaries of the radial and azimuthal extent as well as the vorticity of the vortices. We have distinguished two main families : (i) the incompressible family, which is stable and quasi stationnary ; (ii) the compressible family, moving and exciting density waves. We found them surviving more than 1000 orbits, a clear confirmation of their observability.Finaly, we have caracterized the inward migration of the vortices as a fonction of their shape, their vorticity, but also of the pressure gradient and the scale height of the disk. For the first time, we exhibit a equation relating the migration rate to these parameters. The time scale of the migration ranges from 10^6 to just 100 rotations of the disk. Extremely steep pressure gradients are needed to reverse the migration to an outward regime. Following the alpha viscosity approch, the loss of kinetic momentum due to this migration would be sufficient to sustain the accretion in the dead zone

Full textThis work on metal vessels in northern Gaul aims to analyze changes and regional diversity in a society between Rhine and Seine through a systematical inventory and a study of the geographical distribution of these vessels. The objects take an important place in this study, in order to define a regional typo-chronology of the metal vessels. Nevertheless, the geographical distribution of imported ware highlights commercial or political contacts between Rome and a number of Gallic tribes. In addition, the presence of certain types of vessels, like cauldrons or strainers, in specific contexts can be indicative of their function or status. Above all, this discussion aims at raising questions and opening a new perspective on the Romanization by presenting these data in a systematic and innovative way

Full textThe subject of this PhD thesis is related to the orbital evolution of planets in a protoplanetary disk made of gas and dust around a young star (the first ten million years after the star's formation). The gravitational interaction between planets and the protoplanetary disk gas rapidly changes the distance between the planets and the star. This is known as planetary migration. Many studies have examined how the direction and speed of planetary migration depend on the planet's mass and the physical properties of the disk gas, with the aim to explain the orbital properties of exoplanets. Dust is most often discarded in this kind of studies because its mass content is much smaller than that of the gas and it should therefore have a negligible impact on planetary migration. Yet, dust has gained considerable importance over the past few years owing to the rapidly growing number of multi-wavelength spatially resolved observations of the dust emission in protoplanetary disks. These observations show that dust emission, in particular the cold dust emission at radio wavelengths such as that probed by the ALMA interferometer, can feature structures (spirals, rings and gaps, crescent-shaped asymmetries...) that are very similar to those imparted by disk-planets interactions. For this reason, structures in the dust emission are often interpreted as signatures of the presence of hidden planets. These structures therefore stress the need to better understand how disk-planets interactions generally, and planetary migration more specifically, impact the dust emission in protoplanetary disks. This is the aim of my PhD thesis. To reach this goal, I have carried out 2D and 3D hydrodynamical simulations modeling both the dust and gas of a protoplanetary disk where one or several planets form and migrate. The simulations results have been post-processed by dust and line radiative transfer calculations to compute synthetic maps of the disk emission that are directly comparable to observations. I show that the large-scale intermittent migration towards its star of a planet with a mass typically between those of Saturn and Jupiter is able to generate multiple rings of millimeter dust particles. These annular structures in the dust distribution take the form of bright and dark rings in the radio emission that resemble those observed in several disks. The intensity contrast between bright and dark rings is detectable with ALMA's current sensitivity. Other aspects explored in this thesis include the kinematic signatures of the presence of a massive planet in the gas emission of its disk, and the dust emission at the Lagrange points of a migrating planet

Full textCette thèse étudie l'évolution de ces disques d'accrétion grâce à des simulations numériques magnétohydrodynamiques (MHD) globales en tenant compte du potentiel gravitationnel créé par le disque lui--même.
Dans la première partie, des simulations bidimensionnelles à symétrie cylindrique
permettent de se concentrer sur les propriétés de l'instabilité MRI dans ce type de
disque: en accord avec les résultats obtenus dans les simulations de disques de faible masse, elle croît linéairement puis conduit à la turbulence MHD. La masse importante du disque modifie le profil radial de rotation dans ses parties externes.
Les simulations tridimensionnelles réalisées dans la deuxième partie montrent que
la turbulence MHD et l'instabilité gravitationnelle interfèrent fortement:
l'interaction non--linéaire entre les modes gravitationnellement instables et ceux
excités par la turbulence entraîne une modulation périodique du taux \dac sur l'objet
central. De plus, la turbulence inhibe la formation de planètes par instabilité
gravitationnelle lorsque l'équation d'état est isotherme.
Enfin, dans la troisième partie, des simulations numériques 2D sont effectuées
pour étudier la migration des planètes de masse terrestre dans un disque magnétisé. Elles confirment l'existence, prédite par une étude récente, de deux résonances magnétiques de part et d'autre de l'orbite de la planète. Leur présence modifie le couple exercé par le disque sur la planète. Le sens de migration de la planète s'inverse lorsque le champ magnétique décroît suffisamment rapidement avec le rayon.
