Abstract:

Yes
RF power amplifiers in mobile WiMAX transceivers operate in an inherently nonlinear manner. It is possible to amplify the signal in the linear region, and avoid distortion, using output power back-off; however, this approach may suffer significant reduction in efficiency and power output. This paper investigates the use of Doherty techniques instead of back-off, to simultaneously achieve good efficiency and acceptable linearity. A 3.5 GHz Doherty RFPA has been designed and optimized using a large signal model simulation of the active device, and performance analysis under different drive levels. However, the Doherty EVM is generally poor for mobile WiMAX. Linearity may be improved by further digital pre-distortion, and a simple pre-distortion method using forward and reverse AM-AM and AM-PM modeling. Measurements on the realized amplifier show that this approach satisfies the EVM requirements for WiMAX base stations. It exhibits a PAE over 60%, and increases the maximum linear output power to 43 dBm, whilst improving the EVM.

Abstract:

Le mouvement alternatif est un ensemble de communautés qui, par leur pratique quotidienne, entendent montrer que sont possibles des genres de vie et des modes de production différents de ceux qu'imposent les sociétés industrielles contemporaines. Cette étude met en évidence ce que le mouvement alternatif en RFA a en commun avec les mouvements alternatifs antécédents, du début du siècle à la fin des années 70, et montre aussi ce en quoi il en diffère. Le mouvement alternatif suggéré par ses expériences (ou projets) des solutions concrètes aux crises économiques et sociales de la société dite "établie" et constitue le ferment qui permet à celle-ci d'évoluer
The alternative movement is an alliance of several groups which want to show in their way of living and in their acting that other forms of living and production than the ones prescribed by modern industrial societies are possible. This thesis shows what the nowadays alternative movement in the fgr and earlier alternative movements from the turn of the century till the end of the seventies have in common, but also in which points they differ from each other. The alternative movement presents experiments (or projects) as concrete solutions of economic and social crises and forms the ferment to enable the so-called "established" society to develop

Abstract:

Das Nierenzellkarzinom ist in Europa die 10. häufigste Tumorerkrankung [1]. Da das Prädi- lektionsalter bei 62 Jahren liegt [2] und die Inzidenz mit steigendem Alter zunimmt, geht die Erkrankung häufig mit einer Vielzahl an Komorbiditäten einher. Dies fordert eine Auseinan- dersetzung mit der Anwendung minimal invasiver Methoden, die das operative Risiko mini- mieren. Immernoch wird die Therapie durch radikale Nephrektomie favorisiert. Ziel der Stu- die war es deshalb Entscheidungshilfen für die Anwendung der Radiofrequenzablation (RFA) zu liefern. Daher untersuchten wir an Hausschweinen technische Einflussgrößen auf Behandlungszeit, Ablationsvolumen und Läsionsform bei bipolarer und multipolarer RFA im Vergleich. Dabei ergaben sich nach 3-D-Rekonstruktion größere Ablationsvolumina im mul- tipolaren Modus, wobei sich signifikante Formunterschiede in beiden Anwendungen heraus- kristallisierten. Bei multipolarer RFA ergaben sich größere Inhomogenitäten. Die Ablation kleinerer Tumorgrößen unter 2 cm erscheint mit bipolarer RFA sicher. Patienten mit Tumo- ren bis zu 3 cm profitieren von mutipolarer Radiofrequenzablation. Die Anwendung multi- polarer RFA bei Tumoren größer 3 cm gestaltet sich durch die inhomogene Ablation schwie- rig und bietet ein schwer kalkulierbares Risiko für die Patienten. Es konnte kein Vorteil durch Steigerung des Energietransfers innerhalb eines Modus nachgewiesen werden, da dies mit einer längeren Behandlungszeit einherging, jedoch nicht mit einer Zunahme der Läsiongröße korrelierte. Bei Patienten mit Niereninsuffizienz, Einzelnieren oder bilateralen Tumoren liegt ein Hauptaugenmerk der Therapie auf dem Erhalt der Nierenfunktion. Um eine mögliche Schädigung von gesundem Nierengewebe durch die RFA zu detektieren, färbten wir die Mar- kerproteine aktivierte Caspase3 und HSP70 immunohistochemisch an. Bei Ablation nahe des Nierenbeckenkelchsystems konnten beide Proteine sowohl im System des distalen Sammel- rohrs, als auch im Nierenmark gefunden werden. Hauptsächlich war das Auftreten jedoch auf die Randgebiete der zentralen Koagulationszone begrenzt. Die Radiofrequenzablation scheint daher ein sicheres Verfahren für die Therapie von Tumoren ≤ 3 cm zu sein.

Abstract:

I. Lederer analyse les changements importants du travail feminin qui sont intervenus depuis vingt ans dans les secteurs secondaire et tertiaire en rfa. Elle montre dans quelle mesure la mobilisation intensive des reserves de main-d'oeuvre feminine, ainsi que le processus de stabilisation de l'activite salariale des femmes sont perturbes par la crise de l'emploi, ce qui entraine l'apparition de nouvelles formes de discrimination, l'emergence de divisions et la constitution de nouvelles inegalites entre categories de main-d'oeuvre. Cette analyse fait apparaitre que le chomage est egalement inegalitaire dans ses consequences, dont le caractere complexe affecte les femmes et les hommes au plus profond de leur identite. C'est ce que concretise une description detaillee du vecu des femmes concernees. L'etude repose sur l'exploitation des donnees statistiques de la rfa concernant l'activite, l'emploi et le chomage des femmes. Ces donnees sont comparees avec celles de la situation des femmes en france, resumees dans quelques sous-chapitres
I. Lederer analyzes the important changes in the employment of women which occurred during the last twenty years in the secondary and tertiary sectors in frg. She shows to which amount the intensive use of the reserves of feminine labour, as well as the stabilization process of the salaried activity of women, are affected by the employment crisis, which results in the appearence of new forms of discrimination, the emergence of divisions and the constitution of new qualities between the different categories of labour. This analysis shows that unemployment has also unequal consequences, which complex character deeply affects women and men in their own identity. This is made concrete in a detailed description of the way women really live this situation. The study uses statistical data of frg about the working activity, employment and unemployment of women. These data are compared with the corresponding french data, which are summarized in some sub-chapters

Abstract:

La Seconde Guerre mondiale a profondément perturbé les sociétés européennes. À son issue, le champ est laissé libre à des dynamiques de recomposition passant par des rapprochements ou, au contraire, par des clivages puissants. Les populations françaises et allemandes ont été affectées au premier chef par ces évolutions. Or, comme les organisations syndicales de travailleurs constituent les principales organisations de masses, elles offrent un angle d’approche particulièrement intéressant pour appréhender le dialogue développé dans un contexte marqué par la partition de l’Allemagne, par la Guerre Froide, et par la construction européenne dont l’interpénétration des économies est un des principaux aspects. Cette thèse considère, à la croisée de la question de la réconciliation et de celle d’une coopération à venir, la mise en place des échanges syndicaux entre la France et les deux Allemagnes, examine la pratique des échanges et éclaire les phénomènes de convergence et de crispation
The Second World War profoundly disrupted European societies. When the war came to an end, a dynamic of recomposition, based either on reconciliation or on sharp divisions, took hold of the continent. The French and German populations were the first to bear the brunt of these evolutions. Because of their numerous adherents, trade unions constituted the most important mass organizations of their time, and consequently offer a particularly interesting perspective on the Franco-German dialogue, especially against the backdrop of the division of Germany into two states, the Cold War, and the construction of Europe, of which economic interpenetration was a main aspect. This thesis considers, at the crossroads of a process of reconciliation and of future cooperation, the establishment and structuring of trade unions exchanges between France and Germany, examines exchange practices, and highlights adjoining convergence and tension phenomena

L'enjeu de ce conflit - au niveau le plus élevé - est la discussion sur la rationalité et l'orientation de la politique de sécurité
The current pacifist movement in West Germany is part of an international social movement. It differs from pacifist movements of the past because in its organization it is independent of political parties and other social institutions. The meanings of the action are also different; it is about a patriotic, democratic and social protest. The main issue of this conflict is the discussion about the rationality and orientation of a security policy

Baillieux, Jean. "Effet de l'oxydation sur le comportement mécanique de structures minces en alliages de titane." Thesis, Toulouse, INPT, 2015. http://www.theses.fr/2015INPT0112.

Full text

Abstract:

Les alliages de titane connaissent aujourd’hui un net essor dans les domaines industriels comme l’aéronautique grâce à leur bonne compatibilité avec les matériaux composites et leur très bon ratio rigidité / masse. Leur utilisation concerne des structures thermiquement. Lors d’oxydation, le titane peut voir sa teneur en oxygène augmenter notablement car sa maille alpha présente, à température élevée, une grande affinité pour l'oxygène. La diffusion de l’oxygène conduit à la formation d’un gradient de concentration en oxygène partant de la surface jusqu’au coeur de l’alliage. Cette zone affectée possède des propriétés mécaniques différentes de celles de l’alliage initial. L’étude de l’impact de ces modifications sur les propriétés mécaniques globales d’une structure en titane oxydée s’avère donc nécessaire afin de mieux appréhender le dimensionnement dans les conditions de service. C’est dans cette optique que deux alliages de titane, le Ti-50A et le Ti-6242-Si ont été investigués. La profondeur de la zone affectée par l’enrichissement en oxygène a d’abord été quantifiée après des essais d’oxydation à différentes températures. Les profils de concentration en oxygène, de microdureté y ont été déterminés. Les effets de la teneur en oxygène sur les paramètres de maille ont été analysés en diffraction des rayons X par rayonnement synchrotron. Dans un second temps, des essais de résonance acoustique, de traction et de fluage réalisés entre 500 et 600°C sur des éprouvettes minces avec différentes épaisseurs de zone affectée ont permis de quantifier les modifications des propriétés mécaniques. Une modélisation de la déformation viscoplastique tenant compte de la teneur locale en oxygène dans le matériau a été proposée. Des essais de fluage sur des éprouvettes spécifiques ont permis de comparer la modélisation proposée et les résultats expérimentaux
Titanium alloys are widely used in industrial fields such as aeronautic thanks to their good compatibility with composite materials and their excellent stiffness to weight ratio. During high temperature exposure under air, titanium alloys dissolves large amounts of oxygen. The diffusion of oxygen leads to the formation of an oxygen concentration gradient from the surface to the bulk. The mechanical properties of the affected area differ from those of the original alloy. The study of the impact of these changes on the overall mechanical properties of an oxidized titanium structure is therefore necessary to improve the design of thin components submitted to oxidation. Two titanium alloys, Ti-50A and Ti-50A-6242-Si were investigated. The depth of the zone affected by the oxygen enrichment was first quantified after oxidation tests carried out at various temperatures. The oxygen concentration profiles, the microhardness profiles were determined. The effects of oxygen content on the lattice parameters were analyzed by X-ray diffraction using synchrotron radiation. Vibration tests were performed to determine elastic properties on thin specimens with different thicknesses affected by oxygen enrichment. Tensile and creep tests were carried out from 500 to 600°C to quantify the influence of this oxygen ingress on the mechanical behavior of the two alloys studied. A model is proposed in order to take into account the local oxygen content in the material during creep. This approach is tested on creep tests realized on specific samples. Creep tests on specific samples were used to compare the proposed modeling and experimental results

Abstract:

A new synthetic methodology for the combinatorial preparation of C-terminus-modified Green and Red Fluorescent Protein chromophores is described. This method involves the modification of the previously reported [2+3] cycloaddition reaction scheme to incorporate new R2 groups in the imidate used in the final step. This is achieved through two primary routes: (a) the imidation of nitriles using hydrochloric acid gas and (b) the O-alkylation of amides using a variant of Meerwein's Salt to provide conjugated imidates. The preparation of fluorescent microcrystals and nanofibers from Green Fluorescent Protein chromophore derivatives via the reprecipitation method is also demonstrated. The properties of these microcrystals and nanofibers, especially in relation to the powder obtained from organic solvents, are also explored. Additionally, it is demonstrated that the size and shape of the microcrystals and nanofibers can be modulated with varying experimental conditions for RP. A new class of AIE-active GFP chromophores is reported. These chromophores contain a benzoxazole group on the phenyl ring and varying lengths of alkyl chains on the imidazolidinone nitrogen. These benzoxazole-based chromophores exhibit unique properties in the solid state not previously observed for GFP chromophore derivatives, namely, a broadening of the excitation spectrum and red-shifting of the emission, likely caused by excimer formation. The crystal structure also reveals a unique "hot-dog" stacking motif. Additionally, some projects which require further work are discussed at the end of the thesis. These include a stress-responsive GFP-based polymer and DNA-binding fluorophores.

Abstract:

What explains IMF behavior in Europe between 2008 and 2012? Harshly criticized in Greece, yet tentatively praised in Hungary, the institution found itself playing different roles as it responded to a string of financial crises. Its programs varied substantially in terms of conditionality, financing, and private sector involvement. This thesis explores why, highlighting the changing global financial safety net, which is both expanding and becoming more decentralized due to the spectacular rise of regional financing arrangements (RFAs). Existing theories of IMF behavior assume the Fund to be a stand-alone institution and analyse financial assistance as the outcome from the interplay between creditors, borrowers, and staff. By focusing on dynamics within the IMF, however, they miss how developments outside the institution are increasingly shaping its behavior. This thesis brings in the role of changes in the institutional environment by drawing on the literature on regime complexity. The proliferation of RFAs alters the outside options of all actors, which affects their bargaining power. This opens the way for new strategies, through which creditors can entangle institutions by creating overlaps, borrowers can engage in confrontation between alternative financing institutions, and the IMF can find means to co-work with RFAs. These in turn affect whose preferences shape program design. This argument is tested empirically through process-tracing and comparing three cases of IMF-RFA cooperation in Europe. In Hungary, the IMF led the way in shaping a surprisingly 'generous' program with little constraint from the EU. However, in Latvia, the Fund found itself a 'junior partner' in a program driven by local authorities with the support of an European RFA. In Greece, the interests of creditors were paramount, securing IMF acquiescence through the threat of exclusion. These findings point to significant challenges for the Fund going forward. As RFAs continue to proliferate around the world, the IMF needs to avoid the temptation of striking even more Faustian bargains that keep it at the table of financial assistance at the cost of becoming a junior partner.

Abstract:

This thesis describes single types of wavelength-division multiplex (WDM) according to the International Telecommunication Union (ITU-T). This work offers an overview of components and evaluation of critical parts of network design utilizing WDM technology. There are depicted typical properties, suitable components and channel spacing for each category. Suitable optic fibers according to ITU-T and characteristics of negative effects can be found in the work as well. Furthermore, there are presented most important optic sources, optic amplifiers, optic detectors with filters their requirements and application. They are especially important for achieving operation of WDM system. The fifth chapter considers impact of negative effects in fiber optics and their influence on the system. Then, a WDM system is designed along with management and monitoring the physical layer. The work also presents 1,33 Tbit/s (32 × 42,7 Gbit/s) WDM transmission over 300 km (with three 100 km spans) of post-compensated non-zero dispersion-shifted fiber (NZDSF) LEAF. The capacity of 400 Tbit/s×km is achieved in a single 25,6 nm C band using non-return-to-zero differential phase-shift-keyed modulation (NRZ-DQPSK), balanced detection and erbium-doped fiber amplification. Together with design of transmission system a several simulative analysis has been carried out in order to find the optimum configuration (such as number and distances between amplifiers, length of spans or the way of dispersion compensation) for a high bit rate optical transmission system. It was used a program OptiSystem 8.0.

Full text

Abstract:

This thesis provides a comprehensive history of Supreme Court Free Exercise Clause jurisprudence from 1879 until the present day. It describes how a jurisdictional approach to free exercise dominated the Court’s rulings from its first Free Exercise Clause case in 1879 until Sherbert v. Verner in 1963, and how Sherbert introduced an accommodationist precedent which was ineffectively, incompletely, and inconsistently defined by the Court. This thesis shows how proponents of accommodationism furthered a false narrative overstating the scope and consistency of Sherbert’s precedent following the Court’s repudiation of accommodationism and return to full jurisdictionalism with Employment Division v. Smith (1990). It then shows how this narrative inspired a massive bipartisan coalition in favor of codifying accommodationism, and how this coalition succeeded in passing the Religious Freedom Restoration Act (RFRA) in 1993. The RFRA coalition eventually fractured, as RFRA’s implications began to conflict with principles and objectives of liberal interest groups and the Democratic Party. This thesis posits that the fracture of the RFRA coalition can be traced back directly to confusions over Sherbert’s precedent.

Abstract:

La situation économique peu brillante a laquelle sont confrontés les pays industrialisés, due a une surenchère de pratiques déflationnistes depuis le début des années '80, est le signe d'une grave défaillance du mode de régulation implique par le système de changes flexibles. En effet, les propriétés de ce système en termes d'indépendance des conjonctures économiques et des politiques monétaires nationales se sont trouvées prises en défaut. Cette constatation impose donc un réexamen de l'analyse. Pour corriger l'analyse, nous mettons en évidence un ensemble de mécanismes à travers lesquels nous démontrons une forte interdépendance qui se manifeste en particulier par une transmission négative des effets des politiques monétaires d'un pays a l'autre. Cette transmission crée un conflit d'intérêt entre pays, ce qui nous amené à poser explicitement (en termes de théorie des jeux) le problème de la coordination des politiques monétaires entre économies interdépendantes. Dans une telle perspective, une analyse économétrique appliquée au cas de deux pays européens (la France et la RFA ) va dans le sens d'une validation, sous certaines conditions, des arguments avances en faveur des solutions coopératives par l'analyse théorique. Cependant, cette analyse révèle l'existence d'un certain nombre "d'asymétries" susceptibles d'entraver l'efficacité de la coopération européenne des politiques monétaires au sein d'un système tel que le SME
The world's industrialised countries convergences to the overcontractionary economic policy in the 1980's and the continuing synchronization of major business fluctuations reveal the failor of regulation fashion implicated by the flexible exchange rates. One argument in the case for exchange rate flexibility was that floting rates would insulate economies from foreign disturbances while freeing monetary policy to purpose domestic macroeconomic goals. Experience has show that the indulating properties of the floating exchange rates were exaggerated. - as a consequence, international interdependance has not been eliminated by the flexible exchange rate system. In this context, this study develops a framework for analyzing short and medium term interdependance under floating exchange rates. Imparticular crucial element in this outcome in the negative transmission effects of monetary policies between interdependent countries. In this context, our attention focused on the problem of monetary policy coordination among interdependent economies. - finaly, an empirical evaluation ( applicated to the case of France and FRG) gives evidence to the benefits of European monetary policy coordination and display the potential gains of European strategies

Abstract:

Includes bibliographical references.
The aim of this study was to investigate the effect of extent of simulated uniform corrosion on reinforced concrete beams that have been patch repaired and strengthened in flexure. The most widespread cause of deterioration of reinforced concrete structures is due to corrosion of reinforcement (Bentur et al., 1997). According to Taljsten (2006) some reasons for the corrosion of structures can be attributed to incorrect design and poor construction methods, just to mention a few. Hollaway (2006) suggests that corrosion reduces the area of steel at the corrosion sites therefore decreasing load carrying capacity. The reduced steel area due to corrosion of steel in reinforced concrete beams is considered critical when it can lead to premature failure of a structure. Elgarf (1999) argues that large reductions in flexural capacity, strength and rigidity, which render a beam inadequate for serviceability loads are most likely to occur when localized pitting has extended to many sites resulting in extensive and relatively uniform levels of corrosion.

Full text

Abstract:

La normalisation germano-polonaise après la Seconde Guerre mondiale, surtout entre 1961 et 1975, s’apparente à un changement idéel à travers l’interaction dans le micro-système triangulaire formé par les deux Allemagne (RFA, RDA) et la Pologne dans le macro-système de la guerre froide. Vu le rôle actif d’acteurs non-étatiques dans ces États et à partir de plateformes transnationales (Églises, ONG), on essaie d’aller au-delà de l’histoire diplomatique traditionnelle par une évaluation de l’influence de ces acteurs sur les relations germano-polonaises depuis une position dite « nano-systèmique ». Les enjeux majeurs (parmi lesquels la ligne Oder-Neisse, la question européenne et la sécurité européenne) sont traités de façon chronologique et thématique. La « normalisation » se définit comme le résultat de modifications des identités et des intérêts des acteurs collectifs par l’interaction inter-systèmique – un modèle constructiviste applicable aux rapports germano-est-européens en général
German-Polish normalization after World War II and specifically between 1961 and 1975 can be seen as a mainly ideational change through interaction in the triadic microsystem formed by both German states (FRG and GDR) and Poland in the macrosystem of the Cold War. Given the active role of non-state actors in those three states as well as on transnational platforms (Churches, NGO’s), this study tries to go farther than traditional diplomatic history. Thus it also includes an appreciation of those non-state actors’ influence on German-Polish relations out of a so called “nanosystemic” position. The main issues (among which: the Oder-Neisse line, the German question and European security) are addressed both chronologically and thematically. “Normalization” is defined as the result of shifts in the corporate actors’ identities and interests through intersystemic interaction – an constructivist explanation that could be extended to other case studies of German-East-European relations

Abstract:

Protein dynamics are critical to the structure and function of proteins. However, due to the complexity they inherently bring to the protein design problem, dynamics historically have not been considered in computational protein design (CPD). Herein, we present meta-MSD, a new CPD methodology for the design of protein dynamics. We applied our methodology to the design of a novel mode of conformational exchange in Streptococcal protein G domain B1, producing dynamic variants we termed DANCERs. Predictions were validated by NMR characterization of selected DANCERs, confirming that our meta-MSD framework is suitable for the computational design of protein dynamics. We then performed a thorough NMR characterization of the sequence determinants of dynamics in one DANCER, isolating two mutations responsible for the novel dynamics this protein exhibits. The first, A34F, is responsible for destabilizing the highly stable native Gβ1 conformation, allowing the protein to sample other conformational states. The second, V39L mediates subtle interactions that stabilize the designed conformational trajectory in the context of the A34F mutation. Together, these results highlight the role of protein plasticity in the development of dynamics and the need for highly accurate computational tools to approach similar design problems. Finally, we present an NMR-based characterization of structural dynamics in a family of related red fluorescent proteins (RFPs) and pinpoint regions of the RFP structure where dynamics correlate to RFP brightness. This overview of the RFP dynamics-function relationship will be used in future projects to perform a computation design of functional dynamics in RFPs.

Full text

Abstract:

The goal of this thesis was to adopt a reverse flow injection analysis (rFIA) technique to the fluorometric analysis of the reaction o-phthaldialdehyde (OPA) with ammonium, allowing accurate measurements of ammonium concentrations lower than the detection limit of the widely used indophenol blue (IPB) colorimetric method while accounting for the background fluorescence of seawater. Ammonium is considered an essential nutrient for primary productivity, especially in the nutrient depleted surface ocean where as the most reduced form of dissolved inorganic nitrogen, it is readily assimilated via metabolic pathways. Challenges in the quantification of ammonium require more sensitive analytical techniques for a greater understanding of the biogeochemical cycling of ammonium in the oligotrophic ocean. On-line and automated flow analysis techniques are capable of mitigating some of the challenges. Fluorescent-based methods out-perform colorimetric methods in terms of detection limits and sensitivity. Presented here is the development of an rFIA technique paired with an OPA-sulfite chemistry. For this method, a sulfite-formaldehyde reagent is mixed with the sample stream and then injected with the OPA reagent before being heated. Fluorescence is measured before and at the peak of the OPA injection, differentiating the background fluorescence from the analyte signal. Experiments to optimize reaction parameters and characterize the effects of salinity and potentially interfering species were conducted. The newly developed method offers a reasonable throughput (18 samples per hour), low limit of detection (1.1 nM) ammonium analysis technique with automatic background fluorescence correction suitable for oligotrophic seawater as a preferable alternative to the low sensitivity and high limit of detection IPB colorimetric method.

Full text

Abstract:

The reversed-field pinch (RFP) is a device for magnetic confinement of fusion plasmas. The main objective of fusion plasma research is to realise cost-effective thermonuclear fusion power plants. The RFP is highly unstable as can be explained by the theory of magnetohydrodynamics (MHD). Feed-back control technology appears to enable a robustly stable RFP operation. Experimental control and identification of nonaxisymmetric multimode MHD is pursued in this thesis. It is shown that nonparametric multivariate identification methods can be utilised to estimate MHD spectral characteristics from plant-friendly closed-loop operational input-output data. It is also shown that accurate tracking of the radial magnetic field boundary condition is experimentally possible in the RFP. These results appear generically useful as tools in both control and physics research in magnetic confinement fusion.

Full text

Abstract:

Ce travail explore l'impact des réparations sur les groupes en se concentrant sur la question du temps. Les distinctions opérées par Paul Ricœur entre temps objectif, temps raconté et temps perçu permettent de circonscrire avec précision le champ d'action des réparations : elles sont des vecteurs de reconnaissance caractérisés par leur pouvoir de reformulation du passé. Pour démontrer cela, l'étude s'appuie sur le cas des réparations allemandes à Israël et à la Claims Conference de 1950 à 1990. Ce cas est interprété dans le but de comprendre ce qui a motivé ces gestes, et aussi en vue de justifier le principe des réparations en général : il adopte une méthode herméneutique critique. Les réparations allemandes sont d'abord liées aux théories de la reconnaissance. Les revendications des victimes sont interprétées comme une lutte pour la reconnaissance, les réactions des offenseurs comme un parcours vers la reconnaissance de responsabilité. Le fonctionnement de la reconnaissance est ensuite précisé par une étude des formes qu'elle revêt au fil du temps. Les années 1950 sont celles de la justice civile, c'est-à-dire des réparations monétaires. Ce mode de reconnaissance se caractérise par une façon elliptique de raconter les événements. Dans les années 1960, la justice pénale prend le relais et propose un récit plus concret du passé à travers les témoignages et les verdicts. Dans les années 1970 et 1980, ce sont les gestes symboliques, de nature essentiellement narrative, qui prédominent. En fait, chaque mode de reconnaissance présente une façon distincte de raconter le passé et modifie la perception du temps. Ce pouvoir de reformulation constitue une réplique à l'irréparable
This thesis explores the impact reparations have on groups by focusing on the question of time. It applies Paul Ricoeur's distinctions made between objective, narrated and perceived time. Thus it can show that reparations function as the primary vehicle for recognition due to their rephrasing power. Though they cannot undo the irreparable, they are capable to change the narrative about the past. The case study chosen to prove this point are the German reparations to Israel and to the Claims Conference from 1950 to 1990. The method applied is critical hermeneutics, so the case is not only interpreted in order to understand the motivations for these very reparations but also to justify the principal of reparations in general. The German reparations are first related to the theories of recognition. The claims of the victims are identified as a struggle for recognition, while the reactions of the perpetrators are described as a journey towards the recognition of responsibility. Then the functioning of recognition is specified through a detailed study of the different forms that reparations have taken over time. The 1950s were the years of civil justice, i.e. of monetary reparations. This form of recognition was characterized by an elliptic way of telling the events. In the 1960s, criminal justice took the place, and made a more specific narration of the past possible thanks to the testimonies and verdicts. In the 1970s and 1980s, symbolic acts, essentially narrative, predominated. To sum up, each form of recognition constitutes its distinct mode of telling the past and modifies as a consequence the perception of time. This power to reformulate is an answer to the irreparable

Capes
A esquistossomose e a tricuríase são consideradas um grave problema de saúde pública no Brasil e no mundo. Milhares de pessoas ainda sofrem com as consequências clinicas geradas por essas infecções. Métodos de diagnóstico práticos, sensíveis e específicos são considerados essenciais no auxílio ao controle dessas doenças, vistos que podem identificar os indivíduos e as comunidades que possuem a necessidade de intervenção. Dessa maneira, este trabalho buscou avaliar in vitro o potencial imunorreativo das proteínas recombinantes Frutose Bifosfato Aldolase (rFBPA) do Trichuris trichiura, e de dois fragmentos da proteína Sm200 (rSm200 (1) e (2)) do Schistosoma mansoni, para uso em imunodiagnóstico. Os genes correspondentes as proteínas selecionadas foram avaliados in silico e as sequências codificadoras foram clonadas em vetores de expressão, os quais foram transformados em várias linhagens de Escherichia coli. A purificação foi realizada através de cromatografia de afinidade usando colunas de Ni+ no ÄKTA TM Pure 25® (GE Healthcare). A avaliação da imunoreatividade das proteínas foi determinada por dot blot, utilizando soro de pacientes infectados com S. mansoni ou T. Trichiura e de pacientes sadios, todos provenientes de Salvador Bahia, previamente absorvidos com antígeno de Ascaris lumbricoides para evitar reação cruzada. O método utilizado para expressão, purificação e diálise das proteínas rFBPA e Sm200 rSm200 (1) e (2) mostrou-se eficiente, já que as proteínas recombinantes foram purificadas com alto grau de pureza e concentração. A partir da análise do dot blot foi possível determinar que os soros positivos para T trichiura reagiram com a rFBPA, bem como os soros positivos para S. mansoni reagiram com a rSm200 (1) e (2). Não houve reconhecimento antigênico entre os anticorpos presente nos soros negativos com as proteínas recombinantes rFBPA e rSm200 (1) e (2). Concluindo, nesse trabalho foi possível avaliar a imunoreatividade de IgG total contra as proteínas recombinantes de T. trichuria e S. mansoni, contudo mais estudos são necessários para testar a sensibilidade e especificidade desses antígenos utilizando outros testes imunológicos como ELISA.
