Full textThe term `Lax pair' refers to linear systems (of various types) that are related to nonlinear equations through a compatibility condition. If a nonlinear equation possesses a Lax pair, then the Lax pair may be used to gather information about the behaviour of the solutions to the nonlinear equation. Conserved quantities, asymptotics and even explicit solutions to the nonlinear equation, amongst other information, can be calculated using a Lax pair. Importantly, the existence of a Lax pair is a signature of integrability of the associated nonlinear equation. While Lax pairs were originally devised in the context of continuous equations, Lax pairs for discrete integrable systems have risen to prominence over the last three decades or so and this thesis focuses entirely on discrete equations. Famous continuous systems such as the Korteweg de Vries equation and the Painleve equations all have integrable discrete analogues, which retrieve the original systems in the continuous limit. Links between the different types of integrable systems are well known, such as reductions from partial difference equations to ordinary difference equations. Infinite hierarchies of integrable equations can be constructed where each equation is related to adjacent members of the hierarchy and the order of the equations can be increased arbitrarily. After a literature review, the original material in this thesis is instigated by a completeness study that finds all possible Lax pairs of a certain type, including one for the lattice modified Korteweg de Vries equation. The lattice modified Korteweg de Vries equation is subsequently reduced to several q-discrete Painleve equations, and the reductions are used to form Lax pairs for those equations. The series of reductions suggests the presence of a hierarchy of equations, where each equation is obtained by applying a recursion relation to an earlier member of the hierarchy, this is confirmed using expansions within the Lax pairs for the q-Painleve equations. Lastly, some explorations are included into fake Lax pairs, as well as sets of equivalent nonlinear equations with similar Lax pairs.

Full textIn this thesis we study global smooth solutions of certain Hamiltonian PDEs, in order to capture the possible growth of their Sobolev norms. Such a phenomenon is typical for what is sometimes called "weak turbulence" : a change in the distribution of energy between Fourier modes. We first study a nonlinear evolution equation involving a fractional Laplacian, and we prove a priori estimates on the growth of Sobolev norms. We then introduce an equation where these estimates turn out to be optimal : an integrable Szegő equation with a quadratic nonlinearity, which admits exponentially growing smooth solutions that remain bounded in the energy space. We classify the traveling wave solutions of this quadratic Szegő equation, and show that some of them are unstable. Eventually we find a hierarchy of conservation laws for this equation, which leads us into a deeper study of rational turbulent solutions

Full textThe main purpose of this Ph.D. thesis is to study the long time behavior of solutionsto some Hamiltonian PDEs, i∂_t u=X_H (u), including global existence, growth of high Sobolev norms, scattering and long time approximation by resonant dynamics.In this context, at first we consider the Szegő equation on the circle S1 perturbed bya linear potential, i∂_t u=∏ |u|² u+α∫ u,α∈R, (α-Szegő) where ∏ is the projector onto the non-negative frequencies. For α=0, it turns out tobe the cubic Szegő equation, which was recently introduced by Gérard and Grellier as amathematical toy model of a non-linear totally non dispersive equation.We study the global well-posedness, the integrability and the dynamics of the singularvalues of the related Hankel operators of the α –Szegő equation. Moreover, we establishthe following properties for this equation on a class of invariant submanifolds, with anarbitrary large dimension. For α<0, any trajectory is relatively compact, and all theSobolev norms are bounded on it. For α>0, there exist trajectories on which everySobolev norm of regularity s>½ , exponentially tends to infinity in time.Second, we study the wave-guide Schrödinger equation posed on the spatial domain(x,y)∈R×T ,i∂_t U+∂_xx U-|D_y |U=|U|² U,(WS)Adapting an idea by Hani–Pausader–Tzvetkov–Visciglia, we establish a modified scattering theory between small solutions to this equation and small solutions to the cubic Szegő equation. Combining this scattering theory with a recent result by Gérard–Grellier, we infer existence of global solutions to (WS) which are unbounded in the space L_x^2 H_y^s (R×T) for every s>½

Full textThis thesis is devoted to a PDE obtained by A. Abanov et al (J. Phys. A, 2009) from the hydrodynamic limit of the Calogero-Sutherland Hamiltonian system. A nonlinear integrable Schrödinger-type equation on the Hardy space is obtained and has a Lax pair structure on the line and on the circle. The goal of this thesis is to establish, by using the integrability structure of this PDE, some global well-posedness results on the circle, extending down to the critical regularity space. Secondly, we investigate the existence of particular solutions. Thus, we characterize the traveling waves and finite gap potentials of this equation on the circle. Thirdly, we study the zero-dispersion (or semiclassical) limit of this equation on the line and characterize its solutions using an explicit formula

Full textStigande temperaturer, till följd av klimatförändringar kommer att få stora konsekvenser för jordens fiskpopulationer, däribland atlantlaxen Salmo. Salar L. Störst temperaturförändringar väntas ske vintertid, vilket kommer att påverka S. Salar som övervintrar sin rom. Flera studier har visat att förhöjda temperaturer under embryogenesen ger upphov till morfologiska förändringar hos S. Salar under senare livsstadier. Några studier pekar mot att högtemperaturinkuberad rom torde ge upphov till parr med djupare kroppsform. För att undersöka om höga temperaturer under romstadiet ger upphov till förändringar beträffande kroppsform undersöktes parr (kalla resp. varma) från normal- respektive högtemperaturinkuberad rom. Med hjälp av ett rutnät / box-truss mättes avstånd mellan 10 landmärken på fiskkroppen och en discriminant function analysis DFA användes för att avgöra vilket av avstånden som bäst diskriminerade mellan de båda grupperna. Testet visade en signifikant diskriminering mellan kalla och varma parr beträffande kroppsform där kalla parr hade större huvudmått och varma parr hade djupare mått över stjärtspolen och längre mått mellan analfenans främre infästning och bukfenan. 67,3 % av all parr förutspåddes tillhöra rätt grupp. Dessa resultat är i linje med den litteratur som anger att inkuberingstemperaturen har betydelse för den morfologiska utvecklingen hos S. Salar däremot stödjer de inte den angivna hypotesen.

Full textThe present research titled “Historiography of freedom depriving penalties in Colombia”, provides an account of the punishment and the legal and political transformations of the penitentiary institutions beginning with the first settlers who inhabited the Colombian territory until the advent of the electronic jail in our legal system. The objective is to determine which has been the evolution of the prison sentence in Colombia from the indigenous peoples to the telematic prison, conceiving a critical analysis of confinement, its purposes, its intentions and function; all this, seen from its multiple dimensions, particularly, the preponderant role of prison in Colombia as basis and justification for the punitive legal discourse. For the achievement of this objective a historiographic analysis is proposed, since history presents a characteristic of discontinuity that allows us to review transcendent events or facts in specific temporal ruptures; this led us to place emphasis on its most significant aspects, not to trace the slow curve of an evolution, but to recognize at specific moments of the same the transformation of institutions, in our case those used for imprisonment. We have organized the results of this research in ten (X) chapters that give an account of the relevant historical moments of aboriginal law, colony, republic, modernity and current times; offering an account in each of them of the prison transformations that determined the way to punish and control. In conclusion, we find the role of criminal law especially the execution of penalties in societies, as a remarkable regulating agent of life in community and a social integrator, we emphasize the fact that the human body, from the first settlers to our days, has not ceased from being the place where punishments are carried out and that the evolution of prison sentences in Colombia was marked by a need for social control through hierarchical structures of power, economic capacity and social orthopedics.

Full textThe international peacebuilding intervention model was conceptualized in the 1990’s by the United Nations. It originates from theoretical approaches within Global Administrative Law that promote a materialist and alienating understanding of the concept of sovereignty and monist theories of international law. Peacebuilding aims at establishing liberal rule of law that fosters democratic good governance and the protection of individual human rights. A close scrutiny of this international peacebuilding framework in two exemplary settings in Sudan (Darfur, the “two areas” of South Kordofan and Blue Nile) allows for an analysis of the general legal regime of the peacebuilding model. In the interest of upholding the state’s rule of law, peacebuilding dismantles any competing infra-state legal order. Such so-called autonomous ‘customary’ orders are theorized here following Italian institutionalism and a formalist approach to law. This enables an understanding of how international law maneuvers the constituent elements of such legal orders. Maneuvering of infra-state customary legal orders is enacted through localized and temporary development and transitional justice programs based on the institution of the “trust”. The peacebuilding model consequently appears as a renewed and fleeting form of internationalized administration of territories borrowing from the League of Nations mandate or the United Nations trust systems. By drawing on customary legal orders, international law alienates the constituent elements therein at the price of an acknowledge paradox: international law denies any legal nature to the customary legal orders with which it interacts on a daily basis

Full textThe subtropical latitudes of South America have been experiencing a major hydroclimatic change since the early 1970’s that has had a major societal impact affecting the local economy of one of the most densely populated regions. This change resulted in an abrupt increase in lake levels including Laguna Mar Chiquita, a lake which now covers 6000 km2, while the sedimentary records over the last millennium show a long drying trend. In order to gain a better understanding of the relation between lake level fluctuations and the climate variability in this region, this work aims to simulate the hydrological behaviour of Laguna Mar Chiquita and the relationship with its catchment. The implementation of the lake water balance indicates that lake fluctuations at the beginning of the 1970’s were in direct response to increased runoff in its northern sub-basin, suggesting a tropical climate influence. The coupling of the lake water balance with a hydrological watershed model has led to simulate lake level variations in relation with the climate of the northern sub-basin, highlighting the minor human impact in the recent hydroclimatic transition. For the first time, an integrated basin-lake model in link to global climate is presented combining the results of hydrological basin-lake modelling with the outputs of the climate LMDZ model through a statistical downscaling approach. This novel approach allows to explore the ability of global climate models to accurately represent the regional climate. In addition, it confirms the tropical influence on forcing of recent hydrological variabilities in this region of South America

In the context of Post-Modernity society has been facing numerous changes in the families shapes. One of them is the attempt of a young adult to leave and, later, return to the parental home. In order to understand what motivates such phenomenon, a qualitative research including case study was made. The theoretical assumptions underlining this paper are researches and literature discussing the subject, as well as authors of the Family Systems Theory, but aiming for a differentiated interpretation. The analysis of the interviews was conducted under two guidelines: differentiation and general aspects of the exits and returns of the son to the parents house, a summary about the family s life history and a genogram. The research provided data showing the cycle of leaving and coming back to parent s house is related to certain aspects of a family dynamics, to the relationship between parents and sons and social and economic characteristics of our contemporary reality. It was noted there are few researches about the subject, especially related to its psychological aspects. Data found in current literature refers mainly about the prolonged stay of young adult with his/her parents. Therefore, it is necessary to further research on the topic in question
No contexto da Pós-Modernidade deparamo-nos com inúmeras modificações nos contornos familiares. Uma delas é a tentativa dos filhos de saírem e retornarem ao lar parental. Buscando compreender quais fatores motivam esse fenômeno foi realizada uma pesquisa qualitativa com delineamento de estudo de caso. Os pressupostos teóricos utilizados neste trabalho envolveram pesquisas e literatura que abordam o tema, bem como os autores da Teoria Sistêmica, com vistas no processo de diferenciação. A análise do conteúdo das entrevistas foi realizada em torno de dois eixos: diferenciação e aspectos gerais das saídas e retornos do filho à casa dos pais, elaborado um resumo sobre a história de vida dessa família e construído seu genograma. O conhecimento gerado demonstrou que as idas e vindas à casa dos pais relacionam-se aos aspectos da dinâmica familiar, ao vinculo e relacionamento estabelecido entre pais e filha, e as características do contexto socioeconômico da contemporaneidade. Averiguou-se que há pouco registro de estudos sobre o assunto, principalmente no que se refere aos aspectos psicológicos que o permeiam. Os dados encontrados na literatura atêm-se ao prolongamento dos filhos na casa dos pais, portanto, fazem-se necessárias novas pesquisas acerca do tema em questão

Full textConcerning the communications, the concept's architecture includes those for security as well as administrative communications of airlines and public correspondence of passengers.
From this point of view, the requested globalisation will lead to regulatory and institutional changes, especially for non-security communications as they are regulated by each State overflown, according to Article 30 of the Chicago Convention.
Every legal solution, of course, must take into account the chosen technology. In this domain, the experience of INMARSAT, with the mobile maritime communications by satellites, will be of tremendous importance.
A period of transition, with regional initiatives, will be necessary too before the general implementation of the CNS/ATM concept.

Full textA chromatographic technique has been developed in order to characterize high temperature only soluble polymers. The chromatographic device, built from commercial units, is now reliable. It is an automated and easy to modulate device. The operating conditions for polyolefin fractionation have been determined on the basis of theoretical considerations (self-focusing process) as well as on practical considerations (experience is higt temperature chromatography and in room temperature LAC). These conditions could be easily adapted to other higt temperature soluble polymers (polyamides). Different types of polyolefins have been characterized. The fractionation of non polar polyolefins (polyethylenes, polypropylenes) is delicate and should be improved, but offers yet very interesting perspectives (study of copolymers based on propylene, of polyolefin blends) In the case of polar copolymers based on ethylene, higt temperature LAC allows the determination of the chemical composition distribution within a very short period of time (about 1 hour). This distribution cannot be obtained with other analytical techniques. Higt temperature LAC analysis can also differentiate a copolymer from a polymer blend. LAC - SEC cross fractionation at higt temperature allows a very fine analysis of polymers that can be used for the study of the synthesis - process - structure - properties relationship

Full textLake Masoko (Rungwe Range, Tanzania) provides a continuous sedimentary record of environmental changes during the last 45,000 years. In this work, lipid biomarker content and their carbon isotopic composition (13C) from 10 selected sedimentary intervals allow paleoreconstruction of Lake Masoko since the last glacial period. Phytoplanktonic and bacterial biomarkers show high variability. Ten new structures of di- and mono-cyclic botryococcenes and partially reduced counterparts, triterpenoids specifically produced by Botrycoccus braunii B race, have been described for the first time in a 32 kyr BP interval. Their isotopic composition is highly enriched in 13C probably because of the use of bicarbonate as carbon source. Isotopic composition of n-alkanes shows that, in contrast with other records from tropical Africa, Lake Masoko surroundings are dominated by C3 land plants during the last 32,000 kyr BP. Lake Masoko could have been a refuge for biodiversity during glacial times. On the other hand, lipid biomarker content and their carbon isotopic composition from 18 sediment intervals covering the last 500 years offer a high resolution record for recent paleoenvironmental and anthropic changes. New very long chain C37 to C43 n-alkenes have been described for the first time in Lake Masoko sediments. Insects and other hypothetical producers of such alkenes have been discussed. Phytoplanktonic and bacterial biomarkers show rapid changes in lake ecosystem at decennial scale. Lacustrine productivity clearly increases during the last 500 years. Anthropic pressure on the ecosystem enhances lake productivity since 1940

O presente estudo foi realizado com os jovens participantes do Grupo Ruah, da Casa de Fernando Melo, sede do Lar Fabiano do Cristo, localizado no bairro Jurema, em Caucaia, Ceará. O grupo foi criado com o objetivo de formar as juventudes entre 14 e 29 anos, oferecendo formação profissional, esportes, cursos de artes e temas relacionados à ética, cidadania e cultura de paz, fundamentados numa visão de educação integral. A pesquisa priorizou a ótica dos jovens sobre a experiência no grupo e as repercussões das ações formativas em suas vidas e na comunidade na qual estão inseridos. A pesquisa apresenta enfoque qualitativo, tendo como proposta priorizar a voz das juventudes. Como recurso metodológico, foram utilizadas as oficinas temáticas em cultura de paz, caracterizando a pesquisa participante com o objetivo de coletar saberes e percepções dos sujeitos pesquisados. Realizou-se ainda pesquisa bibliográfica, documental e exploratória. Para a coleta de dados, recorreu-se à observação participante, entrevistas semiorientadas e grupos focais. Como suporte teórico para as reflexões sugeridas, lançou-se mão de autores como Abramo (1997, 2003), Dayrell (2003, 2007), Freire (2011, 2013), Jares (2002, 2007), Matos (2001a, 2001b, 2003, 2006a, 2006b, 2006c) e Yus (2002a, 2002b, 2009). As juventudes anunciam a importância do Lar Fabiano como espaço para a sociabilidade dos jovens, atuando como referência no acolhimento e na assistência à comunidade. As experiências com o Grupo Ruah registram mudança de postura em suas trajetórias e histórias de vida, favorecendo o despertar para noções de ética, tolerância e empatia no cotidiano. Cabe destacar o impacto das oficinas temáticas junto aos jovens, denotando em suas falas e experiências uma mudança considerável e significativa de valores e uma nova ótica em favor da cultura de paz.

Le groupe a été créé ayant comme objectif former des jeunes de 14 à 29 ans, leur offrant des cours professionnels, des sports, des cours d’arts et de formation humaine à travers l’Éducation de l’Être Intégral. Entre les années 2012 et 2013 le groupe a participé de formations en culture de paix. La recherche a priorisé le regard des jeunes sur l’expérience au sein du groupe et les répercussions des actions formatives dans leurs vies et par conséquent dans la communauté dans laquelle ils sont insérés, donc, elle présente une approche qualitative. Comme ressource méthodologique, on a utilisé les ateliers en culture de paix, en caractérisant la recherche participative, pour collecter des savoirs et des perceptions des sujets recherchés. On a réalisé aussi une recherche bibliographique, documentée à travers l’analyse des documents institutionnels du Lar Fabiano, publications en sites, et en plus, une recherche d’exploitation sur la place de la recherche. Pour la collecte de données, on a fait une observation participative, des interviews semi-orientées et des groupes cibles. Comme support technique pour les réflexions suggérées, on a utilisé les auteurs Abramo (1997, 2003), Dayrell (2003, 2007), Freire (2011, 2013), Jares (2002, 2007), Matos (2001a, 2001b, 2003, 2006a, 2006b, 2006c) e Yus (2002a, 2002b, 2009). Les jeunesses annoncent l’importance du Lar Fabiano comme un espace pour la sociabilité des jeunes, agissant l’institution comme référence en accueil et en assistance dans la communauté. Les expériences avec le groupe Ruah résultent en changement d’attitude en leurs trajectoires et histoires de vie, favorisant l’éveille pour les notions d’éthique, de tolérance et d’empathie dans la vie quotidienne. On surligne l’impact des ateliers thématiques auprès des jeunes, indiquant en leurs paroles et expériences un changement considérable significatif de valeurs et une nouvelle conception en faveur de la culture de paix.

Full textThis thesis focuses on the methodology and results of the diagnosis of eutrophication of Nokoue lake in Benin (West Africa). It dealt mainly with the question of water hyacinth infest. The problem of water hyacinth, a consequence of eutrophication and the need for a systemic approach by computer modeling have been reported. The chemical quality of water and sediment were monitored for two years (2006 and 2007). The results confirmed eutrophic status of Nokoue lake and showed the water quality changes with seasons. The production of water hyacinth is regulated by salinity with a threshold of growth lower than in temperate zone (10 ‰ for Nokoue against 15 ‰ in temperate zone). The model results show that nutrient inputs are mainly from the Sô River (97% N 89% P). Salinity has a dominant effect on the integrated index of water hyacinth growth (SII) in all followed stations

Full textIntroduction and objective In southern European countries, the smoking epidemic is still evolving and it shows differences according to sex and age. Scarce studies have analyzed social inequalities in smoking in a long period of 21 years, considering initiation and cessation dynamics as well as second-hand smoke exposure in a comprehensive way in the South of Europe. Moreover, no studies have been found which use the electronic medical record of Primary Healthcare to analyze the social inequalities in smoking cessation programmes in Spain. The objective of this thesis is to analyze the evolution of the smoking epidemic in the Basque Country, according to social class, educational level and a socioeconomic deprivation index from 1986 to 2007, by sex and age groups. Methods This was a cross-sectional time trend study on the population aged >16 years using the Basque Country Health Surveys of 1986, 1992, 1997, 2002 and 2007. For the analysis of inequalities in the participation in cessation programs, a cross-sectional study on the population aged >16 belonging to any health centre of Araba was done. In this case, socioeconomic information of census tracks was used to obtain the MEDEA deprivation index. Age-adjusted prevalences and means were calculated according to social class and educational level, and for the participation in cessation programmes according to the MEDEA deprivation index. To summarize the magnitude of inequalities, the relative index of inequality was calculated as well as the population attributable risk. Age-adjusted means and summary of inequalities was done by means of covariance analysis. Survival curves were calculated and the relative risks of starting smoking were estimated using Cox´s proportional hazard regression models. Calculations were performed separately by sex and for two age groups (25-44 and >44). Results Basque males have diminished their smoking prevalence while women show a stabilized prevalence during the last years. Young population has evolved towards the last stage of the epidemic, with an increasing concentration of smoking in disadvantaged groups. In young women and old men, a change has been observed along the period towards a more frequent smoking among the most disadvantaged groups. The role of initiation and cessation inequalities as determinants of smoking inequalities differed considerably by age and sex. Anti-smoking advice was more frequent among more disadvantaged young population and cessation programmes among more disadvantaged men. Inequalities in second-hand smoke exposure differed by place, and also by age and sex. Conclusions Inequalities in smoking are relevant and have widened from 1986 to 2007 in the Basque Country, especially among the youngest population. The changing pattern of these inequalities, the emergence of new persistent smoker profiles, and the different roles of initiation and cessation dynamics need to be taken into account to improve the results of tobacco control policies and their effect on smoking inequalities.

Full textaux erreurs.
La méthode LAR (Locally Adaptive Resolution) de base a été élaborée à des fins de compression avec pertes à bas-débits. Par l'exploitation des propriétés intrinsèques du LAR, la définition d'une représentation en régions auto-extractibles apporte une solution de codage efficace à la fois en termes de débit et en termes de qualité d'images reconstruites. Le codage à débit localement variable est facilité par l'introduction de la notion de région d'intérêt ou encore de VOP (Video Object Plane).
L'obtention d'un schéma de compression sans perte s'est effectuée conjointement à l'intégration de la notion de scalabilité, par l'intermédiaire de méthodes pyramidales. Associés à une phase de prédiction, trois codeurs différents répondant à ces exigences ont vu le jour : le LAR-APP, l'Interleaved S+P et le RWHT+P. Le LAR-APP (Approche Pyramidale Prédictive) se fonde sur l'exploitation d'un contexte de prédiction enrichi obtenu par un parcours original des niveaux de la pyramide construite. L'entropie des erreurs d'estimation résultantes (estimation réalisée dans le domaine spatial) s'avère ainsi réduite. Par la définition d'une solution opérant dans le domaine transformé, il nous a été possible d'améliorer plus encore les performances
entropiques du codeur scalable sans perte. L'Interleaved S+P se construit ainsi par l'entrelacement de deux pyramides de coefficients transformés. Quant à la méthode RWHT+P, elle s'appuie sur une forme nouvelle de la transformée Walsh-Hadamard bidimensionnelle. Les performances en termes d'entropie brute se révèlent bien supérieures à celles de l'état-de-l'art : des résultats tout à fait remarquables sont obtenus notamment sur les
images médicales.
Par ailleurs, dans un contexte de télémédecine, par l'association des méthodes pyramidales du LAR et de la transformée Mojette, un codage conjoint source-canal efficace, destiné à la transmission sécurisée des images médicales compressées sur des réseaux bas-débits, a été défini. Cette technique offre une protection différenciée intégrant la nature hiérarchique des flux issus des méthodes multirésolution du LAR pour une qualité de service exécutée de bout-en-bout.
Un autre travail de recherche abordé dans ce mémoire vise à l'implantation automatique des codeurs LAR sur des architectures parallèles hétérogènes multi-composants. Par le biais de la description des algorithmes sous le logiciel SynDEx, il nous a été possible en particulier de réaliser le prototypage de
l'Interleaved S+P sur des plate-formes multi-DSP et multi-PC.
Enfin, l'extension du LAR à la vidéo fait ici l'objet d'un travail essentiellement prospectif. Trois techniques différentes sont proposées, s'appuyant sur un élément commun : l'exploitation de la représentation en régions précédemment évoquée.

Full textAnalysis of high resolution bathymetric data and acoustic sub-bottom profiles acquired during the summers of 2014 and 2016 in the Manicouagan reservoir allowed the identification of numerous forms and sedimentary processes on the slopes and lake floor of former Lake Manicouagan. The following geomorphological analysis aims at better understanding the basin’s sedimentary dynamics following the deglaciation. Reaching 322 m deep, Lake Manicouagan was the deepest know lake east of the Great Lakes, before the flooding of the Manicouagan reservoir, whose depth now reaches 452 m. Lake Manicouagan can be divided into three areas: The north area, with a flat lake floor and steep slopes eroded by channels. The central area, where the deepest basins can be found. The south area, with an hummocky lake floor and gentler slopes, eroded by large gully systems. Before the flooding, sedimentary supply to the lake floor was dominated by river sources, through their deltas, and by gravity currents, causing the erosion of channels and gullies. The flooding of the reservoir caused a rise in the importance of mass movements in sedimentary transport to the lake floor, while eliminating river imput transport to the deep basins. The river sediments are now mostly deposited on the shelves and shores of the Manicouagan reservoir.
Bianco, Giuseppe. "Restructuring Sovereign Debt : Private Creditors and International Law." Thesis, Paris 1, 2017. http://www.theses.fr/2017PA01D075.
Full textThis thesis considers the legal framework of sovereign debt restructuring in relation to private creditors and the relevant rules of public international law. The research question is : What is the actual and potential role of public international law in sovereign debt restructurings ? The current legal framework is fragmented, and a multitude of actors and practices coexist. Political expediency governs the process and the outcomes, with little room for customary rules or general principles of law. The case law reveals the challenges for both domestic courts and international tribunals in dealing with sovereign debt restructurings. The contractual approach provides incentives for creditors to attempt creative litigation, which disrupts negotiations. Investment arbitration has proved an inadequate response. The inconsistencies among the different fora bring about unsatisfactory results for creditors and debtors alike, let alone the implications for legal certainty. For the future prospects, the concepts of odious debt and state of necessity can provide limited improvements, at best. Their content and contours appear too ill-defined to be relied upon by States wishing to shield a restructuring. The reform of the legal framework for sovereign debt restructuring has set a competition between approaches based on public international law and on private law. This has been most evident with the process at the United Nations General Assembly and the concomitant modification of contractual clauses. A future framework could potentially feature less avenues for litigation, a focus on the human rights of the debtor population, and a middle ground shaped by the European Union
