Abstract : The field of literature taken as a sociological phenomenon has enlightened and deepened our knowledge and appreciation of several national literatures, and the works of Pierre Bourdieu and Georg Simmel in this field are now considered ground-breaking. In Québec, the Groupe de recherche sur l’édition littéraire au Québec (now operating under the name « Groupe de recherche sur l’étude du livre au Québec ») has been particularly active in studying the sociological conditions that make literature possible in this Canadian province. Parallel to this, the Équipe de recherche interuniversitaire en littérature anglo-québécoise (ÉRILAQ) has gathered researchers interested in the “contact zone,” to borrow an expression from Catherine Leclerc and Sherry Simon, that is Anglo-Quebec literature. This dissertation will combine these two interests in order to study in greater depth the discourse and works of the poets of the Jubilate Circle, a network of poets writing in English in Québec at the turn of the twenty-first century. It will not only seek to prove the existence of a literary circle, it will attempt to showcase how the circle itself has contributed to advancing its members’ literary careers. In keeping with Pierre Bourdieu’s theories of cultural, symbolic and social capital, this dissertation will present, from the outset, a prosopographical sketch of the four poets that make up the Jubilate Circle, and examine the conditions in which they met, bonded as a group (of friends and of colleagues) and came to found the Jubilate Circle. Following this, the instances in which capital of all kinds (symbolic, cultural and social) were exchanged by the four poets will be examined through a close reading of correspondence, dedications, book jacket blurbs and even of the poetry itself. In an attempt to identify the homogeneous in the cacophony of discourse, to paraphrase Marc Angenot, the Jubilate Poets’ discourse on Canadian poetry, enunciated in interviews, essays, book reviews and in the press will then be examined. This will provide a better understanding of the position they hold, or wish to hold, within the field of Canadian poetry and indeed within its canon, existing or future. Finally, an analysis of the poetry they have produced will serve to underscore those aspects of their discourse that are deemed particularly relevant and will highlight areas in which some contradictions may be observed. As a whole, this dissertation will shed some light on the production of poetry, of its criticism and of its publication not only as a literary phenomenon, but also as a profoundly social one. // Résumé : L’étude du champ littéraire en tant que phénomène social a su éclairer et approfondir notre appréciation de plusieurs littératures nationales, et les travaux de Pierre Bourdieu et de Georg Simmel à cet égard sont aujourd’hui considérés fondateurs. Au Québec, le Groupe de recherche sur l’édition littéraire au Québec (aujourd’hui connu sous le nom « Groupe de recherche sur l’étude du livre au Québec ») a jeté les assises dans l’étude des conditions sociologiques qui rendent le phénomène littéraire possible dans cette province canadienne. Parallèlement, l’Équipe de recherche interuniversitaire en littérature anglo-québécoise (ÉRILAQ) réunit des chercheurs qui s’intéressent à cette “zone de contacte”, pour reprendre l’expression de Catherine Leclerc et de Sherry Simon, qu’est la littérature anglo-québécoise. Cette thèse combinera effectivement ces deux champs de recherche afin d’étudier de manière plus approfondie le discours et les œuvres des poètes du “Jubilate Circle”, un réseau de poètes publiant en anglais au Québec au tournant du vingt-et-unième siècle. Elle cherchera non seulement à prouver l’existence d’un cercle littéraire, mais tentera également de démontrer par quels moyens ce même cercle a pu contribuer à l’avancement des carrières littéraires de ses membres. Suivant les théories sur le capital culturel, symbolique et social énoncées par Pierre Bourdieu, cette thèse brossera, dans un premier temps, le profil prosopographique de chacun des acteurs du Jubilate Circle et se penchera sur les conditions qui ont favorisé leur rencontre, le bourgeonnement d’une amitié et d’une collaboration littéraire à long terme et la création du cercle littéraire. En second lieu, les instances dans lesquelles des échanges de capital ont lieu seront scrutées grâce à une lecture détaillée de la correspondance, des dédicaces, des textes de quatrième de couverture et même de la poésie elle-même. Dans le but de faire ressortir l’homogène que recèle la cacophonie du discours, pour paraphraser Marc Angenot, le discours tenu par les poètes du Jubilate Circle au sujet de la poésie canadienne contemporaine, énoncé lors d’entretiens, dans des essais littéraires, des comptes rendus et dans les quotidiens de ce pays sera examiné. Une telle étude permettra de faire la lumière sur leur posture et sur la position qu’ils occupent, ou souhaitent occuper, dans le champ de la poésie canadienne, voire dans son canon littéraire, présent ou futur. Enfin, une analyse de la poésie produite par ces quatre poètes sera l’occasion de souligner et d’illustrer certains aspects particulièrement significatifs de leur discours et révélera quelques instances dans lesquelles certaines contradictions peuvent être observées. Dans son ensemble, cette thèse vise à jeter un nouvel éclairage sur la production d’une poésie, de sa critique et de ses instances de publication non seulement en tant que phénomène littéraire, mais bien en tant que phénomène profondément social.

Thesis (MPhil)--University of Stellenbosch, 2003. / ENGLISH ABSTRACT: In this thesis, 'shadow' is investigated as an object of thought and (analogically connected to this) of perception. This dialectical process is structured through means of a series of experiments and Plato's allegory of the cave, which is interpreted as a process directed towards selfconciousness. This process is further explained through thinkers such as, Blumenberg, Heidegger, Levinas en Voegelin. The purpose of this study is to break with the self-evident way in which 'shadow' is 'normally' treated and to bring back about a sense of astonishment for it. / AFRIKAANSE OPSOMMING: In hierdie tesis word die 'skaduwee' as waarnemingsobjek en (analogies verwant daaraan) as denkobjek ondersoek. Hierdie dialektiese proses word gestruktureerd met behulp van 'n aantal eksperimente en Plato se grotgelykenis, wat geinterpreteer word as programmaties van die proses van selfbewuswording. Hierdie proses word verder toegelig aan die hand van denkers soos Blumenberg, Heidegger, Levinas en Voegelin. Die doel van die ondersoek is om die vanselfsprekendheid waarmee daar met die fenomeen van die skaduwee omgegaan word te deurbreek en weer verwondering daarvoor op te roep. / NEDERLANDSTALIGE SAMENVATTING: In deze thesis wordt de 'schaduw' als waarnemingsobject en (analogisch verwant daaraan) als denkobject onderzocht. Dit dialectische proces wordt gestructureerd met behulp van een aantal experimenten en Plato's grotvergelijking, die geïnterpreteerd worden als een proces gericht op zeltbewustwording. Dit proces wordt verder toegelicht aan de hand van denkers zoals, Blumenberg, Heidegger, Levinas en Voegelin. Het doel van het onderzoek is om de vanzelfsprekendheid waarmee met het fenomeen van de 'schaduw' omgegaan wordt, te doorbreken en er opnieuw verwondering voor op te roepen.

This paper examines the role that military has played in the political development of the former Union of Soviet Socialist Republics and the modern Russian Federation. By utilizing the theoretical tenets of Eric Nordlinger, this paper endeavors to update and hopefully revise his classic work in civil-military relations, Soldiers in Politics. Chapter one of this paper introduces many of the main theoretical concepts utilized in this analysis. Chapter two considers the Stalinist totalitarian penetration model that set the standard for communist governments around the world. Chapter three follows up by addressing the middle years of Khrushchev and Brezhnev. Both reformed the military in its relation to the party and state and made the armed forces a more corporate and professional institution. Chapter four pinpoints the drastic changes in both the state and armed forces during Gorbachev's perestroika and glasnost. The military briefly ventured to a point it never gone before by launching a short coup against the last Soviet president. Chapter five focuses on the last ten years in the Russian Federation. While still a professional organization typical of the liberal model of civil-military relations, the armed forces face great uncertainty, as economic and social problems demand more of their time and resources. Chapter six concludes by speculating on the future of Russian civilmilitary relations and reconsiders the importance of Nordlinger's elegant yet parsimonious work.

Cette étude, qui s'intéresse aux appropriations de l'Antiquité grecque au XXe siècle, se propose d'analyser les impacts de la lecture de Platon sur le développement de la pensée politique et éthique de Hannah Arendt. Notre approche du sujet est historique et philosophique. Premièrement, nous considérerons la toile de fond biographique, intellectuelle et historique de cette lecture. La relation intellectuelle entre Hannah Arendt et Martin Heidegger reçoit une attention particulière, puisque le Platon arendtien présente parfois des similarités avec celui de Heidegger. Nous considérerons également la réception de Platon en Allemagne entre la période de Weimar et l'après-guerre : les lectures idéologiques de l'époque nazie, et le débat autour du statut de Platon en tant qu'ancêtre du totalitarisme, clamé par Karl Popper, ont assombri la réputation philosophique de Platon jusqu'à la fin du XXe siècle. Nous trouvons des échos de ce climat intellectuel particulier dans le traitement de Platon chez Arendt. Dans un deuxième temps, nous examinerons les thèmes et les motifs de la lecture arendtienne en observant minutieusement une sélection d'ouvrages, d'essais, d'ébauches d'Arendt, en plus des notes du Journal de pensée (Denktagebuch) et des extraits de dialogues de Platon sur lesquels s'appuient sa lecture. Arendt déconstruit, transforme, altère et utilise ces textes afin de démontrer que notre tradition de pensée politique s'est édifiée sur un mépris de la politique qui trouve sa source dans la pensée platonicienne. Ce mépris culmine dans la pensée de Marx et le totalitarisme. Mais les réflexions d'Arendt sur la pensée, le jugement et la conscience, et son traitement du cas Eichmann suggère qu'elle s'approprie par moments la pensée de Platon. Des comparaisons avec d'autres penseurs émigrés allemands, qui s'inspirent aussi de Platon et des Grecs pour édifier leur pensée politique, Leo Strauss et Eric Voegelin, vont nous permettre d'affiner notre compréhension du Platon d'Arendt. / This study, which concerns the appropriations of Greek Antiquity in the 20th century, proposes to analyze the impacts of the reading of Plato on the development of Hannah Arendt's political and ethical thought. Our approach of this subject is historical and philosophical. First, we will consider the biographical, intellectual and historical background of this reading. The intellectual relationship between Hannah Arendt and Martin Heidegger receive a special attention, since Arendt's Plato is sometimes similar to the heiddeggerian one. We also consider Platonic reception in Germany between the Weimar period and the postwar era : the ideological readings of the Nazi era, and the debate surrounding Plato's status as the forebearer of totalitarianism, as claimed by Karl Popper, darkened Plato's philosophical reputation until the end of 20th century. We find some echoes of this particular intellectual climax in Arendt's treatment of Plato. Second, we will examine the themes and motives of arendtian reading by scrutinizing a selection of Arendt's books, essays, drafts, and notes from the Denktagebuch, and excerpts from the Platonic dialogues that informs her reading. Arendt deconstructs, transforms, distorts and uses these texts in order to show that our tradition of political thought was founded on a contempt for politics that finds its source in Platonic thought. This contempt culminates in Marx's thought and totalitarianism. But Arendt's reflections on thinking, judgment and conscience, and her treatment of Eichmann's case suggests that she sometimes appropriates Plato. Some comparisons with other German Émigrés thinkers who also reads Plato and the Greeks to inform their political thought, Leo Strauss and Eric Voegelin, will enhance our understanding of Arendt's Plato.

TITLE: Picture of illness and death in contemporary German literature for children and youth (The analysis and didactic adaptation in the context of selected works of world literature) SUMMARY:Presented thesis deals with literary reflections on illness and death in contemporary German literature for children and youth. The theoretical part explains the basic concepts such as illness, death, child and developmental stages of childhood, literature and literature for children and youth. These themes are then further processed. In more detail is the work devoted to analyzing literary works with that theme. The works are examined in terms of literary aesthetic and thematic components, composition and language components. In the practical part, the work focuses on the students perception of researched topic and work with specific literary texts. The final section compares the aspects of reception on illness and death of students of Czech and Austrian schools at the age of 14 to 19 years based on questionnaires filled in by those students which were used as the main research material. KEYWORDS: illness, death, contemporary German literature for children and youth, Jutta Treiber, Sigrid Zeevaert, Petr Pohl, Eric-Emmanuel Schmitt, intercultural aspects

This thesis tells the story of an historical tradition of radical literacy and literature that is defined as the British radical literary tradition. It takes the meaning of literature at its broadest understanding and identifies the literary and educational relations of what E.P. Thompson terms 'the making of the English working class' through its struggle for literacy and freedom. The study traces the developing dialectic of literary radicalism and the emergent hegemony of capitalism through the dissemination of radical ideas in literature and a groundswell of public literacy. The proposed radical tradition is defined by the oppositional stance of its participants, from the radical intellectual's critical texts to the striving for literacy and access to literature by working class people. This oppositional discourse emerged in the fourteenth century concomitant with nascent capitalism and has its literary origins in utopian vision. This nascent utopian imagination conceived a democratic socialism that underpinned the character of much of the following oppositional discourse. The thesis establishes the nexus of the oppositional discourse as a radical literary tradition and the earliest instances of adult education in autodidacticism and informal adult education. The ascent of middle class power through the industrial revolution is shadowed by the corresponding descent of the working class into poverty. Concomitant with this social polarisation is the phenomena of working class literary agency as the means to political and economic agency. While Protestant dissenting groups such as the Diggers and Levellers were revolutionary activists, it was Methodism that formed a bulwark against revolution. Yet it was their emphasis on self-improvement that contributed to an increasingly literate populace. Radical texts produced and disseminated by individuals and organisations and read by autodidactics and informal reading groups are seminal in the formation of a working class identity. Spearheaded by the Chartist movement, education became a central ethic of working class politics and the civil struggle for economic and political justice throughout the nineteenth and well into the twentieth centuries. The avant garde movements of the early twentieth century are analysed as a strand of this tradition. The narrative of the thesis then moves to the penal colony of Australia and explores the radical literary tradition's development there. Early colonial culture is seen as having a strong impetus towards a developing a native literary expression of the new land. Where conservative colonial literature struggled to differentiate itself from formal British literary models, the radical heritage and its utopian vision of a working man's paradise gave definitive expression to the Australian experience. This expression was strongly influenced by Chartist ideals. The British radical literary tradition is thus seen to have had a dominant influence in the development of a native radical literary tradition that strove to identify the national character. Socialist thought developed in Australia in concert with that in the parent culture, and anarchist and libertarian trends found a ready home amongst independent minded colonials. Yet, in preventing the formation of a native aristocracy the small radical population made a compromise with liberalism that saw a decidedly conservative streak develop in the early labour movement. There were little in the way of sophisticated radical literary offerings at first, but from the mid-nineteenth century a vanguard of radicals produced a thriving native press and other fugitive text forms. At the turn of the century the native radical literary tradition was vibrantly diverse, with a definitive style that claimed literary ownership of the Australian character. However, exhausted by the battles over WWI conscription and isolated by censorship, the Communist Party of the Soviet Union was able to subsume the vanguard position from the socialists. The Party laid claim to the Australian radical literary tradition, at once both strengthening it with the discipline of a Marxist ideology and diminishing its independence and diversity. Party literary theory centred upon the issue of class, developing a doctrine of socialist realism that communist writers were expected to practice. How well a writer adhered to socialist realist principles became a measure of their class position and loyalty. Drawing more from primary sources, the thesis develops an analysis of the intellectual development of the Australian post-WWII writer Eric Lambert through his experience of class instability during Depression and war. The study examines Lambert's decision to join the Party and his literary response to his experiences of war, the Party, the turmoil of 1956 and life after the Party. Lambert's body of work is then analysed as the unintentional memoir of a writer working as an adult educator in the radical literary tradition. Lambert's struggles, for artistic independence within the narrow precepts of Party dogma and with class tensions, were common amongst intellectuals committed to the communist cause. Like many of his peers, Lambert resigned from the Party at the end of 1956 and suffered a period of ideological vacuum. However, he continued to write as a Marxian educator, seeking to reveal that which makes us human in the humanity of ordinary people. It is concluded that, while the Party did much to foster disciplined cohesion, the mutual distrust it generated amongst its intellectuals suppressed the independent thought that had kept the radical literary tradition alive. Although the Party developed an ideological strength within the radical literary tradition, its dominance over thirty years and subsequent fall from grace acted to fragment and discredit that centuries-old tradition which it subsumed. An argument is made for a reinvestment of the centrality of the radical literary tradition in the education of adults for the maintenance of social justice and the democratic project.

This study brings the insights of Slavoj Žižek’s Lacan-inspired approach to bear upon a series of influential 20th century plays and their engagement with what Lacan calls the Real. The plays to be explored share a focus on experiences, events or encounters which transcend, exceed, disrupt, and in some cases shatter characters’ normal, familiar realities. Examined through the lens of Žižek, these confrontations with the sublime and the fantastic reveal a crucial relation to the plays’ contemporary contexts, prompting us to “look awry” upon the dynamics of our own symbolically-regulated reality and the ever-changing and precarious nature of our relation to it. Similarly crucial is the relation of the Lacanian Real to our theatrical forms and modes of perception in the theatre. In staging “encounters with the Real,” these plays prompt us simultaneously to explore the ways in which the Real operates —and “appears” — in our own theatrical experience, ensnaring our gaze and the force of our desire. The study offers a Žižekian approach to works including Peter Shaffer’s Equus, John Mighton’s Possible Worlds, S. An-sky’s The Dybbuk, or Between Two Worlds, Caryl Churchill’s The Skriker, Tony Kushner’s The Illusion, and Eric-Emmanuel Schmitt’s Enigma Variations.

This study explores the choral cycle as a genre and analyzes in depth four representative choral cycles, all of them American, and all composed in the twentieth century. Choral cycles are multi-movement choral works intended by their composers to be performed as sets. The term “choral cycle” has been used for only about a hundred years; similar genres include song cycles, for solo voice, and cantatas, usually for soloists and choir. Choral cycles, however, typically use several poetic texts unified by common theme or common author, and do not typically contain solo movements. The evolution of the use of the term by some composers and publishers has been inconsistent, but it seems to have been an effort to describe compositions that were inadequately described by other genre names. This study shows that composers and musicologists have used the term with increasing frequency. The four choral cycles analyzed in this study are The Hour-Glass by Irving Fine, American Madrigals by Kirke Mechem, Voices by Stephen Paulus, and Five Hebrew Love Songs by Eric Whitacre. These four cycles demonstrate widely divergent compositional techniques, performing force requirements, and uses of text. As such, they illustrate the wide range of possibilities within this genre. In addition to the detailed analysis of the aforementioned choral cycles, this study also provides background into the historical predecessors of choral cycles. An appendix offers a list of numerous other choral cycles for consideration. / Choral cycles in historical context -- The hour glass by Irving Fine -- American madrigals by Kirke Mechem -- Voices by Stephen Paulus -- Five Hebrew love songs by Eric Whitacre -- Summary and conclusions. / School of Music

En una tesi anterior (Puig, 2004) es varen estudiar els aspectes mecànics vinculats al desfibratge i als consums energètics associats al procés de desintegració per acabar quantificant les forces implicades en el procés d'individualització dels components de diferents paperots. Aquest estudi, ha permès conèixer les condicions de desintegració que condueixen a un mínim consum energètic, aspecte complementari al reciclatge i destintatge del paperot però molt important per aconseguir un procés realment sostenible.Degut als requeriments del mercat, hi ha un altre aspecte o vessant realment important com és l'eliminació de tinta. Aquest procés, malgrat la complexitat industrial, es pot reduir o simplificar en dues etapes: la desintegració i la flotació. Ambdues, per raons d'eficàcia i condicionades pels agents químics que s'utilitzen, es realitzen en medi fortament alcalí (entorn d'un pH a 12). Aquest fet, genera una forta contaminació (DQO elevada) i per tant, és un procés poc respectuós amb el medi ambient.Els factors que condicionen treballar en medi alcalí són principalment, el despreniment de la tinta del suport, clarament accelerat en medi bàsic i fonamental per un bon destintatge i la utilització de tensioactius aniònics. Aquests tensioactius són sensibles al pH i la seva eficàcia disminueix en medi neutre o quasi neutre.Atès el que s'ha exposat, s'ha plantejat aquesta tesi que porta per títol "Aspectes Físics i Químics del Destintatge de Paper Revista mitjançant Tensioactius Catiònics", com un estudi del procés de destintatge de paper revista recuperat parant especial atenció a les variables físico-químiques i mecàniques del procés i a la seva influència en el despreniment i fragmentació de la tinta, així com en el procés d'eliminació de la tinta per flotació per tal d'avaluar la viabilitat d'un procés de destintatge en medi neutre enfront del destintatge alcalí convencional. S'ha utilitzat, com a paperot a destintar, el paper revista ja que aquest tipus de paper representa un percentatge elevat del paper recuperat a la Unió Europea. A més, aquest tipus de paper és utilitzat habitualment en les plantes de destintatge industrials per millorar les propietats de les suspensions destintades de paper de diari.La utilització de tensioactius catiònics és deguda a que la seva activitat no es veu afectada pel pH de la suspensió. Així, durant la comparació dels processos de destintatge en medi neutre i en medi alcalí, les eficàcies dels processos no es veuran influenciades pel grau d'ionització del tensioactiu.Donada l'absència d'estudis sobre la influència de les variables del procés en les mesures de concentració efectiva de tinta residual (ERIC) i ja que s'ha emprat aquest paràmetre per avaluar el despreniment i fragmentació de la tinta durant l'etapa de desintegració. En primer lloc, s'ha plantejat un estudi fonamental de la influència que poden tenir les variables del procés (granulometria, concentració de tinta i tipus de suport) en aquest paràmetre. Pel que fa a l'etapa de flotació, s'estudiarà l'efectivitat d'aquesta etapa, posant especial atenció a la capacitat del tensioactiu per eliminar tota la tinta despresa en l'etapa de desintegració. A més, donada la poca informació bibliogràfica referida als mecanismes de flotació amb tensioactius catiònics i la influència que té l'adsorció d'aquests agents per part de la suspensió paperera en l'etapa de flotació, s'ha dut a terme un estudi de l'adsorció dels tensioactius catiònics per part dels components d'una suspensió paperera.Per tant, la tesi realitzada té com a objectius: Estudi fonamental de les mesures de ERIC (concentració efectiva de tinta residual) amb suports específics. Estudi de la desintegració en medi neutre i comparació amb la desintegració clàssica. Modelització del desfibratge de paperot a l'etapa de desintegració. Estudi de l'eliminació de tinta per flotació en medi neutre i comparació amb la flotació clàssica. Estudi del mecanisme d'adsorció de tensioactius en suspensions de cel·lulosa sintètica i de paperot. / A previous thesis (Puig, 2004) have studied the mechanical aspects related to defibering and to energetic consumptions related to the disintegration process to end up quantifying the forces involved in the process of individualization of the different components of recovered papers. This study has permitted to know the disintegration conditions that lead to a minimum energetic consumption which is a complementary aspect to the recycling and deinking of waste paper but very important to get a really sustainable process.Due to the requests of the market, there is another really important aspect in the wastepaper recycling process which is the elimination of ink. Ink elimination, can be summarized in two unit operations: Disintegration and flotation. Both unit operations are strongly conditioned by the chemical agents used. Usually disintegration is carried out in a highly alkaline medium (pH 12). This fact, cause a high contamination in process waters (high COD) and therefore, the process is not environmentally friendly. The factors that condition the high alkaline medium are mainly ink detachment from the cellulosic support which is clearly accelerated by the alkaline medium, and the utilization of anionic surfactants. These surfactants are sensitive to the pH and its efficiency diminishes in neutral or almost neutral medium. So it has been proposed this thesis entitled "Aspectes Físics i Químics del Destintatge de Paper Revista mitjançant Tensioactius Catiònics" (Physico-chemical aspects of deinking of OMG using cationic surfactants) as a study of the viability of neutral deinking versus alkaline deinking.OMG has been used since this grade represents a high percentage of paper recovered in the European Union. Besides, this grade is used in industrial deinking plants to improve deinked ONP properties.Cationic surfactants are used because its properties are not affected by the pH of the suspension. So during the comparison of deinking processes in neutral and alkaline medium, the process efficiency will not be influenced by the surfactant ionization degree.OMG deinking study begins with a modelization of disintegration followed by an analysis of ink detachment and fragmentation achieved in neutral conditions and comparing them with the results obtained in alkaline conditions.Due to the absence of studies on the influence of the variables of the process in the measurements of effective residual ink concentration (ERIC) and since this parameter has been used to evaluate the detachment and fragmentation of ink during disintegration itself, it has been done a fundamental study of the influence of process variables such as ink particles size, ink concentration and type of the cellulosic support on this parameter.Regarding flotation stage, the effectiveness of this process will be studied focusing on the capability of the surfactant to eliminate all the ink detached during disintegration. Since deinking process is strongly influenced by surfactant adsorption on the different components of wastepaper suspensions and that there is a little information related to flotation mechanisms when cationic surfactants are used it has been accomplished a study of the adsorption of cationic surfactants by the components of a wastepaper suspension (cellulosic support and ink) and the results have been compared with the adsorption of an anionic surfactant in the same conditions.Therefore, the thesis has the following objectives: Fundamental study of ERIC measurements with specific supports. Study of neutral disintegration in comparison of traditional alkaline disintegration. Modelization of paper defibering during disintegration process. Study of ink elimination by means of a flotation process in neutral medium in comparison with a traditional alkaline flotation process. Study of the adsorption mechanism of surfactants by a wastepaper suspension.
