Full textWe have investigated the Gard and the eastern Paris basin environmental reconstruction by using U-series dating of speleothems. The first aim of this study was to validate the high resolution U-series dating of small size samples over the recent period (0- 10 kyr) for which this method is of difficult use. For this period, we also have tested the 226 Ra dating techniques for the U/Th dated speleothem. For the whole period on which U/Th is valid, several correction methods were compared in order to take into account bias due to detrital material within these impure carbonates. These methodological investigations enabled to investigate several research axes. We discussed the origin of speleothems breaking from a Gard cave. Speleothem U/Th dating has been used for a chronological scale for the Eastern Paris basin karstification. We have shown the importance of the presence and the erosion of a non carbonated cover overlying the karstified limestone on the speleothem uranium composition. .

Full textHigh Temperature Reactors (HTR), is one of the innovative nuclear reactor designed to be inherently safer than previous generation and to produce minimal waste. The most critical metallic component in that type of reactor is the Intermediate Heat eXchanger (IHX). The constraints imposed by the conception and the severe operational conditions (high temperature of 850°C to 950°C, lifetime of 20,000 h) have guided the IHX material selection toward two solid solution nickel base alloys, the Inconel 617 and the Haynes 230. Inconel 617 is the primary candidate alloy thanks to its good high temperature mechanical and corrosion properties and the large data base developed in previous programs. However, its high cobalt content has to be considered as an issue (nuclear activation). The more recent alloy Haynes 230, in which most of the cobalt has been replaced by tungsten, present characteristics similar to the 617 alloy. The objective of this thesis is to study the high temperature mechanical behaviour of both alloys in relation with their microstructural evolutions. The as received microstructural observations have revealed primary carbides (M6C). Most of this precipitates are evenly distributed in the materials. Few M23C6 secondary carbides are observed in both alloys in the as received state. Thermal ageing treatments at 850°C lead to an important M23C6 precipitation on slip lines and at grain boundaries. The size of this carbides increases and their number decreases with increasing ageing duration. The intragranular precipitation of secondary carbides at 950°C is more limited and the intergranular evolution more important than at 850°C. The microstructural observations and the hardness evolution of both alloys show that the main microstructural evolutions occur before 1,000 h at both studied temperatures. The mechanical properties of the Inconel 617 and the Haynes 230 have been studied using tensile, creep, fatigue and relaxation-fatigue tests. Particularly, the properties at 850°C and 950°C have been evaluated using several stress levels (creep), strain rates (tensile) and relaxation duration (fatigue). The effects of initial treatments have also been studied, i.e.ageing treatments effects on creep and tensile properties and cold-work effects on creep properties. At high temperature, the as received Inconel 617 does not show classical creep behaviour. This study shows the importance of the fast carbides precipitation on their mechanical properties, despite the fact that the Inconel 617 and the Haynes 230 are listed as solid solution alloys. Low cycle fatigue tests with and without holding time have been performed at 850°C under air and under vacuum on both alloys. The results showed that cyclic hardening, cyclic stability and life time are closely related to the duration of the holding time. Furthermore, a single thermally activated mechanism operates over a very wide range of strain rates, corresponding to tensile tests, creep and relaxation. The link between microstructure and mechanical behaviour presented in this thesis helps to determine the advantages as the operation limits of each alloy in order to manufacture a nuclear power plant heat exchanger

Full textAll the talk about relativism points out the difficulties related to the Church in a more globalised world. The ecclesial institution is no longer in the heart of the social organization. The Church has to make a way for herself in the midst of a constellation of systems which are, at times, put in competition one with the other. That raises ineluctably a question about the Church. What can one say about Her ? The Bible does not frankly answer the question, except that it offers several metaphors that have been more or less successfully taken by theologians. They constitute as many ecclesial models. These various representations convey a certain image of the Church and what she stands for. No paradigm seems to carry a unanimous vote. However the brotherhood presents more advantages than the others. That is why we consider it to be the best expression of the Church. lt is from this point of view that we have formulated the problematic of our essay on "Brotherhood in Christ: theological bases of ecclesial being and its African incidence". While combining the structural dimension with the brotherly feelings, the theology of the brotherhood surpasses the dead ends linked only with the institution on one hand and the virtues of the other. It goes beyond the limits set by human traditions. Indeed Church-Fraternity is primarily factor of relations. It connects man to God and draws closer people one to another. This doctorate thesis is the deepening of the research I started while I registered for the Master programme. It deals with the criteria for recognition of true ecclesial characters, which is ecclesiality. For some, the Church is a heavy legal machine, without heart and soul that crushes everything in its path. She makes her weight felt. Otherwise she does not manifest any compassion to those who do not comply with her guidelines. This Church seems distant and indifferent to people and their concerns. For others, the Church manifests the ideal of community life between women and men who answered the call of Jesus, have submitted their will to Him and made themselves his disciples. This is the picture one can get from the narrative of the Acts of the Apostles. This primitive communism was the specificity of the nascent community of Jerusalem. Instead Jesus directs people to the knowledge of the Father and leads them into a filial relationship. It then clearly appears that people are brought into a changed relationship. This is the dimension of the adoptive filiation by which they are recognized God's children, sisters and brothers in Jesus Christ, the only Son of God, and brother and sister vis à-vis others. This fraternity embraces everyone. Indeed filiation or being a direct descendant of someone establishes henceforth a new relationship in Jesus Christ. This community of sisters and brothers is realized only in the Holy Spirit. The Church, as a Fellowship, differs from any other company, for its social cohesion is based on the Gospel

Full textThe purpose of this work is to analyse in which way the six charterhouses of Franconia could be regarded as a coherent ensemble, and if it is possible to recognize a franconian identity of the Carthusian monks. The territory of the Land zu Franken is contested since the contemporaries tend to define the territory according to their private interests. The order of the Carthusian monks settles tardily in Franconia. They propose a renewal of the contemplative orders which were so far incarnated by the Benedictines and Cistercians whose expansion finishes at the end of 13th century. A study of the institutional mechanisms of the order, accompanied by a prosopography of the officers of the area shows that the monks of Franconia fit within the border framework of the province of lower Germany. The officers, by their displacements limited within the area of the province, build the network between the communities and thereby provide a structure of lower Germany. The process of foundation shows that the order of the Carthusians is used by the founders with an aim of representation of their might which explains why the houses are joined together in the valley of the Main, where the lordships stand in a fierce competition. The funerary liturgy of the Carthusians also explains the choices of the founders for this observance, since some monasteries become places of burials. Finally, the relations of the franconian Carthusians with the world are considered by their literary activities, as well as by their engagement in the beginning of the Reformation.

Full textThe Church is constantly emerging. With a calling to be reborn in each new context, the Church in post-Christendom must rise to the dual challenge of remaining faithful to the Gospel while being fresh and culturally relevant. In the first section, this thesis examines new types of Churches, identified as “Emerging Churches” which, in recent years, have been trying to meet this challenge. These communities, developing in western countries either within or on the fringes of the entire denominational spectrum, are trying to practice the way of Jesus within postmodern cultures. They are, thus, seeking to be faithful to their place and time. These Churches, by focusing on mission, community development or innovative worship, offer various approaches while nevertheless sharing a common driving force. They pave the way for a more open consideration of certain contemporary ecclesiological issues which make up the second part of this study. Bringing together the writings and ideas of the authors and leaders of the Emerging Church movement with those of British missionary theologian Lesslie Newbigin creates a vision of a missional, incarnational and experiential Church

Full textThe production of high pressure (HP) and high temperature (HT) wells has considerably increased in the last decade. It is therefore needed to reassess the risks of corrosion in always more severe environments. This work was three fold to better assess the risk of Sulfide Stress Cracking (SSC) in these environments. Firstly, there was a need to improve prediction methods for the evaluation of HP/HT environments severity, especially the in situ pH calculation. A model was which taking into account the non-ideal behaviour of gas and liquid phases in equilibrium. The determination of the in situ pH and the acid gas fugacity at high pressure and high temperature is more accurate. In a second part of the work, the impact of CO2 partial pressure (PCO2) on surface reactions and hence on the risk of SSC was examined. Electrochemical and hydrogen permeation measurements in the absence of an iron sulphide film showed that CO2 induces an increase of both cathodic reactions kinetics and hydrogen charging in the steel, especially at low H2S partial pressure (PH2S). In the last part of this work, SSC tests were performed at constant pH and constant PH2S, with various PCO2 from 0 to 100 bar. The objective was to experimentally confirm that increasing PCO2 increases the SSC risk, as inferred from the electrochemical study. Unfortunately, experimental artefacts linked with autoclave test conditions did not lead to clear conclusions on this point. However, this work shows that conventional tools might lead to underestimate SSC risks at high PCO2 and low PH2S. In these specific conditions, the new results presented in this report may contribute to improve materials selection criteria for high pressure and high temperature conditions

Full textTheology flows from the word of God. Its task, therefore, is to explicate what characterises that word. In Christ, God speaks in person to mankind, which is why we need to establish which philosophy of the human word is capable of serving theological reflection. Christ’s words and actions are relative to His divine I Am ; his words and actions are carried by a new, divine judgement and intention. This brings us to some fundamental questions : faith and intelligence ; history and metaphysics ; theology and the mystical. These pairs are inseparable in Christianity. A theological wisdom must be both appealing and rigorous as regards the truth ; what is it that allows it to be just that ? A philosophy which, thanks to love, explicates the final cause. Finally, we look at the unity and the organisation of theology : Christ himself determines the order of theology in the organic development of its different areas

Full textAn issue has been ever recurring : are the discords which have been going on since sixteenth century between Catholics, Lutherans, Calvinists as much anthropological as theological ? As this question can be supported it seems suitable to determine these anthropological disagreements, analyse them and wonder whether or not they are obstacle to the Κοινωνία. A study concerning the situation during the XVIth century has allowed to conclude that the anthropological concepts conveyed by an existential philosophy have played a mojor role in the severing within the Western Church. The return on the thoughts developed by Pannenberg, Moltmann and Rahner, theologians of three different confessions, allows us to tell that in the XXth. century man’s vision has always an incidence on the theological concepts but are less and less separative and are often gifts to be shared. The analysis of ecumenical dialogues have clearly shown that theanthropological disagreements have been partly reconciled and are now subject to consensus, even a joint declaration on the doctrine of justification. Today we have to take up a challenge about a declaration on the ministry in order to share the body of Christ at the same table. A differing consensus method could be a help to find a complete communion

Full textThis dissertation examines the use of the term σήμερον (“today”) in Luke-Acts (22 occurrences), the Pauline letters (Romans 11:8; 2 Corinthians 3:14, 15) and the Epistle to the Hebrews (1:5; 3:7, 13, 15; 4:7 [twice]); 5:5; 13:8). It gives special attention to the possible influence of the Deuteronomic “today” in the New Testament. Two main hypotheses are at the heart of this study. First, the word “today,” in Deuteronomy as well as the three New Testament corpora under consideration, becomes a theological theme of its own. In effect, it is argued that its various occurrences reveal the presence of reflective work on “the today.” Second, in the minds of the three New Testament authors who give attention to this motif, there seems to be an awareness of certain theological associations that are bound up with the Deuteronomic “today.” In diverse manners, they intentionally transpose this Old Testament motif in the light of the Christ event. By the end of this investigation, it becomes apparent that Luke’s today, Paul’s today and the today of the Epistle to the Hebrews, while each possessing unique characteristics, all contribute to emphasize the same key theological concepts, such as the fulfillment of Scripture, an inaugurated and progressively realized eschatology, the coming of salvation, the heralding of the good news and the proclaiming of God’s Word

Full textThe long-term durability of joint replacements is based on their corrosion resistance and wear behavior. Whatever the materials used, degradation products (metal ions and wear debris) are formed due to the aggressiveness of body fluids and the biomechanics of the joints. Generally, these products are associated with post-operative complications and, as a result, their effects are critical clinical concerns. In this respect, tribocorrosion is a serious consideration in the performance of joint replacements. This work aims to contribute to the improvement of the understanding of the degradation mechanisms of a CoCrMo alloy, used as a joint prosthesis, by understanding the coupling of mechanical loads and cellular activity. This thesis has been structured according to a progressive approach, which begins with the study of the electrochemical behavior of a simulated physiological environment conducive to cell culture (RPMI-1640). Metal alloys and cells were successively added to the study system. The tests revealed that the oxidation of CoCrMo is accelerated in the presence of carbonaceous species and organic compounds, and that the cells are involved in the release of metal ions. A biotribocorrosion device has been developed to evaluate the influence of degradation products on cellular metabolism. This comprehensive multidisciplinary study combined experimental techniques from electrochemistry, biology and tribology to highlight the importance of biomaterial surface chemistry on tribocorrosion resistance and cytotoxicity. Finally, an experimental methodology was proposed in this work, in order to better understand the interaction between simulated physiological fluids and biomaterials

Full textThe present study describes the results of a 2 week perturbation experiment where speakers'' vocal tract shape was modified due to the presence of an artificial palate. The aim of the work is to investigate whether speakers adapt towards acoustic or articulatory targets. Speakers were recorded regularly over the adaptation time via electromagnetic articulography and acoustics. Immediately after perturbation onset speakers'' auditory feedback was masked with white noise in order to investigate speakers'' compensatory behaviour when auditory feedback was absent. The results of acoustic measurements show that in vowel production speakers compensate very soon. The compensation in fricatives takes longer and is in some cases not completed within the two weeks. Within a session and for each speaker the sounds can be distinguished solely by acoustic parameters. The difference between the session when no auditory feedback was available and the session when auditory feedback was available was greater for vowels with less palatal contact than for vowels with much palatal contact. In consonant production auditory feedback is primarily used in order to adapt sibilant productions. In general, adaptation tries to keep or enlarge the articulatory and acoustic space between the sounds. Over sessions speakers show motor equivalent strategies (lip protrusion vs. tongue back raising) in the production of /u/. Measurements of tangential jerk suggest that after perturbation onset there is an increase in articulatory effort which is followed by a decrease towards the end of the adaptation time. The compensatory abilities of speakers when no auditory feedback is available suggest that speakers dispose of an articulatory representation. The fact that motor equivalent strategies are used by the speakers, however, supports acoustic representations of speech. It is therefore concluded that articulatory representations belong to the speech production tasks. However, since they are modified as soon as the acoustic output is not the desired one any more, they rather function in the domain of movement organisation and the acoustic representations dominate.

Full textThis thesis deals with the Elucidarium, the first theological work written by a prolific 12th-centuy author, Honorius Augustodunensis. Created at the very end of the 11th-century, the Elucidarium has had a great success all over the medieval West even since. Even though the text is not unknown to scholars, the knowledge of this work suffers from many divisions and oppositions. The cleavage between "erudite" and "vulgar" cultures, the division between the monastic intellectual world and that of urban schools, the distinction between doctrinal analysis of the text and its textological study, the opposition between the history of vernacular traditions of this work and the investigations into its original Latin version — all this makes our knowledge of this text fragmentary. The principal goal of the present study is to put an end to these divisions and to determine the true scope of the history of the Elucidarium in the Latin West, from its creation up to the end of the Middle Ages. The only way to achieve this goal is to combine systematically all the existing interpretations and observations with the data provided by handwritten testimonies (such as medieval catalogues, lecture notes, etc.), and by works inspired by the text. This is the only way that make it possible to write a “total history” of the Elucidarium and to reassess this remarkably successful work, and, in the end, to make our knowledge of this text more accurate. The results of the analyses undertaken within the research project are presented in the three parts of the thesis. The first deals with the author and his work. This part’s three chapters inventory critically all the reconstructions of Honorius' life, but also re-examine the doctrinal content of the Elucidarium: its plan and structure, which appear to be inseparably connected. The main purpose of this scrutiny is to suggest a new interpretation of what Honorius envisaged to achieve with his work and how the text has been intended to function. The second part and its two chapters trace the first century of the reception of the text. By documenting the dissemination of the Elucidarium, it is possible to formulate a new hypothesis about the place and circumstances in which Honorius has written his work, but also to see how readers progressively extended its initial function. Finally, the third part of the thesis is dedicated to the history of the Elucidarium in the Late Middle Ages. By the 13th century, the text has gradually spread to many circles, both intellectual and social; it inspired, or was a source of, several works, both in Latin and in vernacular. All this compose the history of the Elucidarium. Although the text has considerably changed its purpose and went far away of the authorial intention, it has not disappeared, it has never stopped to be copied, diffused and read; it has always found its particular niche, remaining an important and relevant book within the cursus librorum, whatever the cultural and social context. In other words, the history of the Elucidarium appears to be much more complex and rich than it has been previously assumed

Full textThe main objective of this thesis was to develop a new parameterization enabling to improve the mixing and representation of clouds in convective boundary layers. We thus developed a parameterization based on the concept EDMF for Eddy- Diffusivity/Mass Flux and in which the mass _ux scheme represents idealized thermal which can exchange air with its environment and whose air parcels can condensate. In the dry part of the updraft, entrainment and detrainment are defined as proportional to the buoyancy and inversely proportional to the vertical velocity in the updraft. This formalism allows the exchanges to adapt depending on the type of boundary layer or the intensity of convection. In the cloud, the buoyancy sort formalism was chosen. Indeed, it is well suited to represent exchanges between the cloud and its environment. Tests in a single column model helped highlight the contribution of such a scheme in the representation of the turbulence but also boundary layer clouds. It allows a good representation of the counter-gradient area and corrects a well-knwon defect of eddy-diffusivity parameterizations. 3D results are presented and demonstrate the need for such a scheme for models with 2. 5km resolution. It has been well implemented in the new operational mesoscale model at Météo-France named AROME

Full textDans le deuxième chapitre nous élaborons des modèles bonds graphs de diverses configurations de systèmes photovoltai͏̈ques. Pour la source PV, nous élaborons, dans une première étape, un modèle complet tenant compte des divers phénomènes physiques qui influent sur la qualité de la source PV. Dans une seconde étape, nous déduisons un modèle bond graph réduit afin de le rendre utilisable dans des applications d'analyse et de commande. Pour les convertisseurs DC/DC, nous rappelons la modélisation par bond graph des éléments de commutation et les modèles bond graph moyens des convertisseurs DC/DC développés dans la littérature. Suite à ceci nous déduisons les modèles bonds graphs des divers convertisseurs DC/DC à utiliser. Le troisième chapitre présente une étude dynamique en linéaire de la stabilité de quelques configurations. Dans le quatrième chapitre, nous étudions la faisabilité d'une commande linéarisante entrée-sortie pour quelques configurations de systèmes PV. Dans cette étude, nous utilisons le concept du bond graph inverse pour déterminer, par une approche bond graph, l'expression de la commande linéarisante entrée-sortie et la nature de la stabilité de la dynamique interne (dynamique des zéros). Le cinquième chapitre est consacré à la présentation de résultats expérimentaux. Ces résultats sont relatifs aux dispositifs expérimentaux réalisés : système de caractérisation de modules et champs photovoltai͏̈ques, système photovoltai͏̈que constitué d'un générateur PV couplé à une motopompe DC à travers un hacheur dévolteur. Ce système fonctionne en MPPT suite à l'implantation d'une loi de commande non linéaire

Full textThe study of the effects of radionuclides and metals on organisms is necessary for the evaluation of their toxicity and their ecological threats. We first aimed to study the impacts of cadmium (Cd) and Uranium (U) on different biological levels of the crayfish Procambarus clarkii after acute and chronic exposures. We evaluated their impacts on mitochondria, oxidative stress responses, on histological structures, and the survival rates. We tried to connect these effects between them and to the bioaccumulation in the gills and the hepatopancreas. We also tried to discriminate the chemo and the radiotoxicity of U by exposing crayfish to either depleted or enriched U (233U: presenting a higher specific activity) using the same criteria of effects. We demonstrated that the gene mt encoding for the metallothionein was always over-expressed in the presence of Cd. Therefore, it seems to be a good biomarker of Cd toxicity in P. clarkii. The follow up of mitochondrial genes expressions (12s, atp6 and cox1), showed that both metals affect mitochondria and that their mechanisms of action do not seem to be always the same. We also observed that U generates more oxidative stress than Cd when comparing the expression levels of genes encoding for antioxidants (sod (Mn) and mt) and the enzymatic activities of superoxide dismutase, the catalase, the glutathione peroxidase and the glutathione S transferase. However, the symptoms of histo-pathological damages after Cd and U contamination were similar in both conditions. After comparing the survival rates of the crayfish, we concluded that Cd was more toxic than the radioelement. Moreover, we demonstrated that the toxic effect of U on P. clarkii exposed to a low environmental concentration is mainly due to its chemotoxicity rather than to its radiotoxicity. We established that, the molecular answers vary according to the intensity and the duration of the chemical stress applied to the organisms. We suggested the use of the expressions of all the studied genes as biomarkers of toxicity of U rather than the enzymatic activities because of their sensitivity. This work proposes mechanisms of actions of U based especially on the molecular responses and confirms the necessity of studying the ecotoxicological profile of this radioelement
