Previous issue date: 2006-03-30<br>In this work it was investigated the influence the in influence of the doping Pr6O11 in the electrical conductivity and in the microstructural properties in the basic ternary system (98,95 – x)%Sn02 1,0% Co0 0,05%Ta205. The used concentration of the doping Pr6011 had varied in 0,05%, 0.5% in mol, remaining constant the concentrations for the Co0 and Ta205. The processing applied was the conventional method of mixture of oxides in ambient atmosphere. The samples had been conformed in 50 MPa and sintered in 1350°C for 2 hours. After the sintering the densification of ceramics was verified with a value of 93,63% for the system with 0,1% in mol of Pr6011. The study of the electrical properties for the varistor system Sn02.Co0.Ta205 Pr6011 was carried out in continuous current in the ambient temperature and in function of the temperature. It was observed that the variation in the concentration of Pr6011 modifies the electrical behavior of the ceramics. The electrical parameters found are of [alfa]= 8,0, Er= 319 volts/cm and Vb= 0,66 volts/barrier for basic ternary system and [alfa]= 17,0 Er= 853 volts/cm and Vb= 1,15 volts/barrier with the addition of 0,10% in mol of Pr6011. The system with 0,05% mol 0.1% in mol Pr6011 presents the same value of the non linearity coefficient of the system with 0,1% in mol, however, with lower values of rupture tension and barrier tension (Er= 708 volts/cm and Vb= 0,98 volts/barrier). To concentration above of 0,1% in mol of Pr6011, the increase of the concentration of this doping, starts to be deleterious to the varistor characteristics. This effects is due to the increase in the concentration of the stannate of praseodymium phase (Pr2Sn207). This crystalline phase with the cassiterita phase (Sn02)was characterized by DRX and EDS and quantified by the refinement of Rietveld.<br>Neste trabalho investigou-se a influência do dopante Pr6O11 na condutividade elétrica e nas propriedades microestruturais no sistema ternário básico (98,95-x)%SnO2.1,0%CoO.0,05%Ta2O5. As concentrações utilizadas do dopante Pr6O11 variaram em 0,05%, 0,1%, 0,3% e 0,5% em mol, mantendo-se constante as concentrações para o CoO e Ta2O5 . O processamento empregado foi o método convencional de mistura dos óxidos. As amostras foram conformadas a 50 MPa e, sinterizadas a 1350ºC por 2 horas em atmosfera ambiente. Após a sinterização verificou-se densificação das cerâmicas, com valor de 93,63% para o sistema com 0,1% em mol de Pr6O11. O estudo das propriedades elétricas para o sistema varistor SnO2.CoO.Ta2O5 Pr6O11 foi realizado em corrente contínua a temperatura ambiente e, em função da temperatura. Observou-se que a variação na concentração de Pr6O11 altera o comportamento elétrico das cerâmicas. Os parâmetros elétricos encontrados são de [alfa] = 8,0, Er= 319 volts/cm e Vb= 0,66 volts/barreira para o sistema ternário básico e, [alfa] = 17,0, Er= 853 volts/cm e Vb = 1,15 volts/barreira com a adição de 0,10% em mol de Pr6O11. O sistema com 0,05% em mol de Pr6O11 apresenta o mesmo valor do coeficiente de não linearidade do sistema com 0,1 % em mol, entretanto, com valores menores de tensão de ruptura e tensão de barreira (Er= 708 volts/cm e Vb= 0,98 volts/barreira). Para concentrações acima de 0,1% em mol de Pr6O11, o aumento da concentração desse dopante, passa a ser deletério para as características varistoras. Esse efeito é devido ao aumento na concentração da fase cristalina estanato de praseodímio (Pr2Sn2O7). Essa fase cristalina, juntamente com a fase cassiterita (SnO2), foi caracterizada por DRX e por EDS e, quantificadas pelo refinamento de Rietveld.

Testo completoAbstract (sommario):
Pr6O11 nanostructures were synthesized through a facile solvent-less method. Nanostructures were prepared by heat treatment in air, using [Pr L(NO3)2]NO3 (L bis-(salicyladehyde)-1,4-butadiimine Schiff base ligand), as new precursor, which was obtained by a solvent-free solid–solid reaction from praseodymium nitrate and Schiff base ligand. The as-obtained nanostructures were characterized by X-ray diffraction
(XRD), scanning electron microscopy (SEM) and ultraviolet–visible (UV–vis)spectroscopy. The obtained results demonstrated that utilizing of this precursor is suitable choice for preparation of Pr6O11 nanostructures with very uniform sphere-like morphology. The photocatalyst activity of as-obtained Pr6O11 was also examined by degradation of 2-naphthol as organic contaminant under ultraviolet light irradiation.

Previous issue date: 2012-03-02<br>Conselho Nacional de Desenvolvimento Científico e Tecnológico<br>This study focused on the Cerium oxide (CeO2) based pigmenting systems, doped with Praseodymium oxide (Pr6O11) and hematite (Fe2O3 – iron oxide) synthesized through the solid state reaction (OM – oxide mixture) and the Pechini method. Simultaneously, CeO2-Pr6O11-Fe2O3 ternary system pigments were synthesized through OM, with the addition of mineralizers. The samples synthesized through OM were wet homogeneized, in isopropyl alcohol, in a horizontal ball mill for 18 hours and dried in oven at 110 C, then thermally treated at 1300 ºC for 3 hours. In samples synthesized through the Pechini method, the process started from the synthesis of the polymeric resin, formed by the citric acid reaction, glycol ethyl, water and the desired oxide salts, kept in thermal blanket at 150 C, under constant agitation for 2 hours, following two thermal treatments at 300 C for 2 hours, and then one at 900 C for 3 hours. After the thermal treatment the pigmenting systems were characterized through XRD, UV-Vis reflectance spectroscopy, scanning electronic microscopy, Raman spectroscopy and thermal analysis, determining the phases present, the colorimetric parameters, band gap values, micro-structural agglomerations and thermal and chemical stability to glass enamel. Single phase pigments were obtained in the binary system CeO2-Pr6O11, with addition of up to 10% Pr6O11 synthesized through OM and up to 3% Pr6O11 synthesized through the Pechini method, whereas the binary system CeO2-Fe2O3, presented single phase only in OM synthesis, with concentrations up to 2% of Fe2O3. More intense shades were obtained in pigments with addition of up to 5% mol praseodymium oxide in the CeO2-Pr6O11 system, and with up to 3% mol iron oxide in the CeO2-Fe2O3 system. The ternary system CeO2-Pr6O11-Fe2O3 presented secondary phase PrFeo3, remaining this phase even with the addition of mineralizers. The pigments applied to low temperature frits (LTF) and windscreen glass (WSG) showed chemically and thermally resistant at 800 C, free of surface defects on the ceramic plates, presenting better dispersion and color homogeneity.<br>A presente pesquisa estudou os sistemas pigmentantes à base de óxido de cério (CeO2) dopados com óxido de praseodímio (Pr6O11) e hematita (Fe2O3 - óxido de ferro), sintetizados pelo método de reação de estado sólido (mistura de óxidos - MO) e pelo método Pechini. Paralelamente foram sintetizados pelo método MO, pigmentos do sistema ternário CeO2-Pr6O11-Fe2O3 com adição de mineralizadores. As amostras sintetizadas por MO foram homogeneizadas a úmido, em álcool isopropílico, em um moinho de bolas horizontal por 18 horas e secas em estufa a 110 C, e tratadas termicamente a 1300 C por 3 horas. Nas amostras sintetizadas pelo método Pechini partiu-se da síntese da resina polimérica, formada pela reação de ácido cítrico, etileno glicol, água e os sais contendo os íons metálicos dos óxidos pretendidos, mantida em manta térmica a 150 C, sob agitação constante, por 2 horas, sendo tratadas termicamente duas vezes a 300 C por 2 horas, e, na sequência, a 900 C por 3 horas. Após tratamento térmico os sistemas pigmentantes foram caracterizados por difração de raios X, espectroscopia de reflectância na região do UV-Vis, microscopia eletrônica de varredura, espectroscopia Raman e análise térmica, sendo determinadas as fases presentes, os parâmetros colorimétricos, valores de band gap, aglomerações micro estruturais e a estabilidade térmica e química frente à esmaltação vítrea. Pigmentos de fase única foram obtidos no sistema binário CeO2-Pr6O11, com adição de até 10% de Pr6O11 sintetizado por MO e com até 3% de Pr6O11 sintetizado por Pechini; já no sistema binário CeO2-Fe2O3, fase única somente em sínteses por MO, com concentrações até 2% de Fe2O3. Tonalidades mais intensas foram obtidas nos pigmentos com adição de até 5% mol de óxido de praseodímio no sistema CeO2-Pr6O11, e com adição de até 3% mol de óxido de ferro no sistema CeO2-Fe2O3. O sistema ternário CeO2-Pr6O11-Fe2O3 apresentou fase secundária PrFeO3, persistindo esta fase mesmo com adição de mineralizadores. Os pigmentos aplicados em frita de baixa temperatura (FBT) e vidro de pára-brisa (VPB) se mostraram resistentes química e termicamente a 800 ºC, sem presença de defeitos superficiais nas placas cerâmicas, apresentando melhor dispersão e homogeneidade da cor.

Previous issue date: 2005-09-30<br>Universidade Federal de Minas Gerais<br>In the last few years, the study of ceramic materials has increased very fast, mainly studies related to advanced ceramics. The several applications of these materials as ceramic pigments in nanometric scale justify more and more the need for a better understanding of the influence of the dopant addition on the final properties. In this present work, it was studied structural and morphological properties of ceramic pigments based on CeO2 doped with different molar percentages of praseodymium, nickel and cobalt. These properties were also analyzed under the influence of oxidizer
(O2) and inert (N2) atmospheres applying different calcination temperatures. The goal of this work was to obtain nanosized ceramic pigments with. The chemical route adopted to obtain materials was the polymeric precursor method. It was obtained stable nanosized pigments, being observed the predominance of the dark red, brown and gray colors for
systems doped with praseodymium, nickel and cobalt, respectively.<br>Nos últimos anos, o estudo de materiais cerâmicos vem evoluindo muito rapidamente, principalmente os estudos relacionados com cerâmicas avançadas. As diversas aplicações envolvendo estes materiais, tal como pigmentos cerâmicos com partículas nanométricas, justificam cada vez mais a necessidade de uma melhor compreensão da influência da adição de dopantes nas propriedades finais. No presente trabalho propõe-se analisar e estudar as propriedades
estruturais e morfológicas de pigmentos cerâmicos a base de CeO2 dopado com diferentes porcentagens molares de praseodímio, níquel e cobalto. Estas propriedades, também foram analisadas sob a influência da adição de atmosfera oxidante (O2) e inerte (N2) nas diferentes temperaturas de calcinação. Um dos principais objetivos foi o de obter pigmentos cerâmicos com tamanho de partícula nanométrica. O processo químico adotado para a obtenção dos pós foi o método dos precursores poliméricos. Foram obtidos pigmentos nanométricos estáveis, observando-se a predominância das
cores vermelho marrom e cinza escuro para os sistemas de céria dopados com praseodímio, níquel e cobalto, respectivamente.

Ce travail de thèse porte sur l'incorporation de charges minérales d'oxyde d'erbium, Er2O3, et d'oxyde de praséodyme, Pr6O11, dans une matrice polymère de type élastomère, ceci dans le cadre d'un projet industriel de remplacement du plomb dans des équipements de radioprotection. L'objet de cette thèse était d'améliorer la dispersion des charges au sein de la matrice par le biais de procédés de traitements chimiques de ces particules. Divers types de fonctionnalisations de surface ont été employés afin de compatibiliser celles-ci avec une matrice organique, notamment par greffage de composés de type acides phosphoniques. Plusieurs acides phosphoniques ont ainsi pu être utilisés avec succès pour la fonctionnalisation des deux types de charges. La caractérisation de ces différentes fonctionnalisations représente une part importante de ce projet. Des techniques d'analyse innovantes, aussi bien directes qu'indirectes ont été employées dans ce but, à savoir de la Py-GC/MS pour la détection des composés ancrés à la surface des charges, de la fluorescence X et de la spectroscopie infrarouge dans un objectif de quantification, mais aussi des études cinétiques de sédimentation des charges dans un milieu liquide organique. Finalement, des composites ont pu être obtenus par mélange des charges, traitées et non traitées, avec une matrice polyuréthane. Des essais de traction ont permis de montrer clairement une amélioration des propriétés mécaniques de certains des composites, grâce à la fonctionnalisation des charges par les acides phosphoniques<br>This thesis focuses on the incorporation of mineral fillers of erbium oxide, Er2O3, and praseodymium oxide, Pr6O11, in an elastomeric polymer matrix, in the context of an industrial project to replace the lead in radiation protection equipment. The actual purpose of this thesis was to improve the dispersion of the fillers in the matrix through chemical treatment processes of these particles. Various types of surface functionalization were used to compatibilize them with an organic matrix, in particular by grafting compounds such as phosphonic acids. Hence, several phosphonic acids have been successfully used for the functionalization of both types of fillers. The characterization of these functionalizations is an important part of this project. Innovative analysis techniques, both direct and indirect have been used for this purpose, namely Py-GC/MS to detect the chemical compounds anchored to the surface of the fillers, X-ray fluorescence and FTIR spectroscopy with a quantification target, but also a study of sedimentation kinetics of the fillers in an organic medium. Finally, composites were obtained by mixing the fillers, untreated and treated, with a polyurethane matrix. Tensile tests have clearly shown an improvement of mechanical properties for some of the composites, due to the functionalization of the fillers by phosphonic acids

Beynon, Richard Jonathon. "'Ugly Lovely' : being a work of creative writing with accompanying critical commentary." Thesis, University of Sussex, 2013. http://sro.sussex.ac.uk/id/eprint/47227/.
Testo completoAbstract (sommario):
The title of the creative work is ‘Ugly Lovely'. The 20,000 word critical discussion of the creative piece has no title, other than that it offers a critical consideration of the relationship between the literary composition and contemporary or traditional achievements in the genre. The creative work concerns a taxi driver named Don, living in the south Wales port of Swansea. He finds his life and culture unsatisfying, but is unable, because of his own lack of will and energy, to leave. His passengers, some of whose lives have an orbit beyond the small-ish Welsh city, bring his sense of dissatisfaction into focus. The work follows a sequence of episodes during which the driver meets and reflects on the remarks and actions of subsequent passengers, and considers his own family and life. Structurally, the work takes the form of a story-cycle concerning or emanating from Don or from the passengers in his taxi. The passenger narratives sometimes present complete stories or self-contained episodes, sometimes broken or partial narratives. All episodes stand in relief against the other fractured narrative running through the work, the driver's self-reflection and re-evaluation of the family life and up-bringing. Thus: 1) Taxi stories – involve the characters who step in and out of the taxi. These stories centre upon a cast of characters who enter the driver's working world, but also present to reader the a secondary cast of characters introduced by the passengers, through the stories they tell. The role and status of the driver shifts as the work progresses. At the close of the work, though the driver's future, like the futures of his town and nation, remains unassigned, he approaches it with a firmer sense of purpose (if not direction). 2) Connected family narratives - gradually present fragments from the history and lives of the main figures in the driver's family. Through these frequently conflicting and contesting narratives, the work delivers a number of perspectives on the history of the town in which the family lived and through which the taxi stories now move. These separate narratives are arranged out of linear sequence, in an order which has greater correspondence to their emotional importance, and in response to triggers set within the various passenger narratives. The contesting nature of the family stories raises questions in the reader's mind about which narratives are privileged, and which reliable. As the work progresses, the realisation comes that none of the narratives is privileged, that all may be unreliable and all contest for dominance and primacy in the driver's mind. The critical element In providing a ‘critical consideration of the relationship between the literary composition and contemporary or traditional achievements in the genre', this commentary will present I. a general introduction to the creative work, II. discussion of the narrative form and organisation of the work, comprising: a. consideration of the ways that the work is shaped by modernist concerns and structures, particularly those of the modernist ‘city novel', b. consideration of the way that the work is structured to present a collection of linked and inter-related narratives, broadly referred to as a short-story sequence III. discussion of the extent to which the work can be placed within the canon of Welsh writing in English; in particular: a. the ways in which the work constitutes a recognisable piece of Welsh writing in English and the extent to which it treats the concerns of one of the national literatures b. the ways in which the work makes considered and constructive use of its setting in Swansea.

Radcliffe, Mark. "What happens to bruised or damaged nurses?" Thesis, University of Sussex, 2014. http://sro.sussex.ac.uk/id/eprint/51407/.
Testo completoAbstract (sommario):
This project is largely creative in nature offering the first half of a now published novel entitled Stranger Than Kindness and a textual and critical analysis of that novel that explores the experience of traumatized or ‘bruised' nurses. The novel, half set in 1989 and half set in 2013, follows the clinical and personal traumatization of two nurses and their tentative steps towards restoration. It reveals a backdrop of a sometimes subtle institutionalized brutality and a culture that lends itself to the individual collection or absorption of difficulty. It uses gentle magical realism to counterpoint the gritty backdrop of the pre-community care asylum of the 1980s and the neoliberal, free market setting of the modern world of healthcare in the second half of the book. It's dénouement is a celebration of whimsy in the face of hard industrialized science. The novel reveals the capacity of the nurse to collect emotional residue, trauma or bruising and be both changed and hurt by the experience of care to the point of being damaged. It essentially resorts to poetics to explore the ‘felt' world of the nurse or carer. In tone and in theme the book is a novel of the emotions. Valuing an emotional literacy over medical rationalism, it seeks to gently reclaim the idea that caring for others is a pursuit or enactment of embodied wisdom rather than just the exercising of scientific knowledge. The critical discussion uses the text of the novel to make three observations in relation to the research question. The first is that the question is political. It is strikingly unaddressed in policy responses to ‘The Francis Report' (2013) and perhaps in terms of mainstream research it is unaskable because it addresses the felt world. In the same way that the novel explores a hierarchy of values in the caring profession, the ensuing critical discussion reveals a hierarchy of knowledge. The second observation is that it is our tacit understanding of what reason is and how we make sense of the world we have constructed that helps make questions about bruised or damaged nurses somehow beyond convention. Iain McGilchrist's The Master And His Emissary (2009) offers a way of making sense of that by exploring the contemporary imbalance between the logical and linear thinking of the left hemisphere and the integrative and imaginative right hemisphere. We have come to prize the measurable over the experiential or contextual and reflective to such an extent that we organize the world accordingly. The third observation, which emerges from the first two and the novel, is the suggestion that nursing is assuming an ill-fitting Cartesian epistemology that cannot do justice to its breadth or holistic need. I suggest that a philosophy that took clearer account of the body, the senses and the felt world would more comfortably accommodate and legislate for the needs of the nurse and the profession of nursing. An embodied realism (Lakoff and Johnson, 1999) that emerges from Damasio (2000, 2012) and Merleau-Ponty (2005) offers the potential to restore a more balanced and less reductionist philosophy that might enable a fuller and more person-centred response to the nursing crises. A further more general observation the thesis makes is that fiction can inform social science and offers a way in which it can do that. Thus it finds itself in a tradition of narrative inquiry (Clandinin and Connelly, 2000). However, it also notices the potential paradox in valuing art as a sociological resource: something that offers us knowledge, meaning and even moral review while turning to cognitive neuroscience to legitimize that methodology.

Eckstein, Sue. "Homage or damage - the scope and limitation of autobiographical fiction." Thesis, University of Sussex, 2011. http://sro.sussex.ac.uk/id/eprint/7583/.
Testo completoAbstract (sommario):
The thesis comprises a novel – Interpreters and a critical commentary. Interpreters The novel explores the notion of identity, the interpretation of the past, the secrets and lies inherent in families, the parent/child relationship and the collective and personal guilt of a generation who grew up in Nazi Germany. It is a work of fiction that has grown out of memory and imagination, informed by original research, family memoirs, and oral history. Interpreters tells the story of Julia Rosenthal, a successful anthropologist, who returns to the suburban estate of her 1970s childhood. During her journey, both actual and emotional, the unspoken tensions that permeated her seemingly conventional family life come flooding back. Trying to make sense of the secrets and half truths, she is forced to question how she has raised her own daughter – with an openness and honesty that Susanna has just rejected in a very public betrayal of trust. Meanwhile her brother, Max, is happy to forge an alternative path through life, leaving the past undisturbed. In a different place and time, another woman is engaged in a painful dialogue with an unidentified listener, struggling to tell the story of her early years in wartime Germany and gradually revealing the secrets she has carried through the century. Critical commentary Autobiographical fiction as a genre can be laden with moral and ethical issues, and I have made their examination the centrepiece of my critical commentary. I have focused on the contractual understanding of the relationship between the author, reader and those written about, the issue of who “owns” memory, and issues relating to a writer's responsibility – and the limits of that responsibility – to their sources. I have examined the tension between “truth” and “fiction” and whether this is something that is particularly problematic in the writing and reading of autobiographical fiction. I have also considered what happens to the writer and the reader when the rules are broken by fake memoir, particularly fake memoir related to recent history and, most particularly, to the Second World War and its aftermath. My reflections on my own novel and its genesis are complemented throughout by discussions of other, mostly twentieth century, authors' and critics' works.

Pestell, Alex. "Geoffrey Hill : poetry, criticism and philosophy." Thesis, University of Sussex, 2012. http://sro.sussex.ac.uk/id/eprint/39686/.
Testo completoAbstract (sommario):
This thesis examines the role played by philosophy in the poetry and criticism of Geoffrey Hill. Despite countless references to philosophy throughout Hill's critical authorship, there exists no study of any length on this vital aspect of his thought. Through close readings of his poetry, criticism, and archival material, I attempt to demonstrate that philosophy has played a more crucial role in Hill's work than has hitherto been assumed. Hill's sceptical attitude to philosophy is intimately connected with his understanding of poetry as a sensate form of cognition. My thesis examines the ways Hill's poetry and criticism responds to the challenges imposed upon this scepticism by a tradition of philosophy that emphasises the importance of the aesthetic to its analyses of modernity's contradictions. I argue that a tradition of Anglophone Idealist thinkers, from S.T. Coleridge, via T.H. Green and F.H. Bradley, to Gillian Rose, is of sustained relevance to Hill's work, shaping the way he thinks about politics, ethics and literature. In particular, German Idealism's attempts to negotiate universality and particularity via an emphasis on the aesthetic bases of critical thought lay the groundwork for an understanding of poetry as a mode of cognition. Reading Hill's poetry from For the Unfallen to Oraclau/Oracles, I try to show the ways in which problems traditionally conceived of as philosophical can be cognised in prosody and syntax. In part a vindication of Hill's elevation of poetry over philosophy, these readings also show the degree to which Hill's ‘craft of vision' is indebted to conceptual and aesthetic models supplied by philosophy.

Testo completoAbstract (sommario):
In this thesis I explore the complex nature of James Joyce's relationship with Giordano Bruno in The Day of the Rabblement, Stephen Hero, A Portrait of the Artist as a Young Man, and Ulysses. I employ an historicist methodology, and examine Joyce's encounter with Bruno in the context of the discursive environment of contemporary Roman Catholicism, specifically in relation to the triumph of Ultramontanism within the Church and the emergence and suppression of Roman Catholic Modernism. I argue that an historicist examination of this relationship provides an extremely effective means of realising some of the urgency and offensiveness of Joyce's critical engagement with contemporary Catholicism. I discuss the manner in which Joyce's encounter with Bruno's writings and legacy in the 1900s steeled him in his own struggle with Catholic orthodoxy, and I explore the significance of the heretical trace of Bruno's philosophical and cosmological writings in Joyce's novels from 1904 to 1922.

Lowe, Sarah Elizabeth. "Players and performances in early modern Gloucester, Tewkesbury and Bristol." Thesis, University of Gloucestershire, 2008. http://eprints.glos.ac.uk/3394/.
Testo completoAbstract (sommario):
This thesis is an analysis of the responses in the early modern period of civic and church authorities to local and visiting groups of players in Gloucester, Tewkesbury and Bristol. It is also an examination of the venues in which these groups performed. Reactions to these groups varied, and this study explores how these, both positive and negative, were affected by economic, legal and cultural factors. The thesis proceeds chronologically, and is thus divided into twenty-year intervals in order to draw the most effective comparisons between the three urban centres over a number of decades. The first period under examination, the 1560s, records the early reaction of the three settlements to the phenomenon of the Elizabethan travelling company. The relationship between the regional authorities and the patrons comes to the fore in the second period, the 1580s, as the dominance of the ambitious Earl of Leicester grew in the region. Legislation decreeing the withdrawal of mayoral control over itinerant troupes at the close of the sixteenth century, the third period, released civic officials from previous obligations and this influenced the level and character of their hospitality towards the ‘noble’ companies. Although evidence is scarce, the records of Gloucester, Tewkesbury and Bristol contain clues to an attitude towards these entertainers during the reign of James I, the final period under scrutiny. The study is based on the extant economic records for the region, as these contain much fruitful information. This thesis consciously places itself in dialogue with the internationally acclaimed REED Project, and draws on the information collated by the editors of the volumes for Bristol and Gloucestershire. A parallel examination of the entries into municipal records of the three towns, and the areas around them, in conjunction with genealogical and topographical evidence, has allowed for an interpretation of the data in a wide regional context, revealing that although each town tolerated players in their municipal spaces, with the officials personally entertaining the companies on some occasions, the reception of the companies varied significantly from town to town and across the historic period.

Testo completoAbstract (sommario):
Le contexte environnemental (réchauffement climatique) et politique (augmentation du parc EnR) entraîne une mutation du paysage énergétique français. Le méthane de synthèse est présenté comme un vecteur énergétique permettant le stockage et le transport de l’électricité renouvelable en surproduction tout en recyclant le CO2 (Power-to-Methane). Un des objectifs de la thèse est de développer un catalyseur actif en co-méthanation d’un mélange post co-électrolyse H2/CO/CO2/H2O/CH4 (projet ANR CHOCHCO). Le catalyseur synthétisé est de type Ni/CZP. L’optimisation de la synthèse coprécipitation par l’utilisation combinée du sel précipitant (NH4)2CO3 et du tensioactif CTAB a mené à un catalyseur performant (absence de poison alcalin et augmentation de la surface spécifique) capable de produire du CH4 à basse température (250 °C) avec un rendement élevé. Le catalyseur a montré une résistance satisfaisante à la désactivation par dépôt de carbone et par frittage, indispensable pour le fonctionnement intermittent du procédé. Un modèle cinétique, de type Langmuir-Hinshelwood, a pour la première fois été développé sur un catalyseur de type Ni/CZP<br>The environmental (global warming) and political (increase of the renewable electric farm) context leads to a mutation of the French energy landscape. Synthetic methane is presented as a energy carrier for storing and transporting renewable electricity in overproduction while recycling CO2, a process called Power-to-Methane. One of the objectives of the thesis is to develop an active catalyst for the co-methanation of a post-co-electrolysis mixture H2/CO/CO2/H2O/CH4 (CHOCHCO ANR project). A Ni/CZP type catalyst was synthesized in this purpose. The optimization of the coprecipitation synthesis by the combination of the precipitating salt (NH4)2CO3 and the surfactant CTAB has led to a high performance catalyst (absence of alkaline poison and increase of the specific surface area) able to produce CH4 at low temperature (250 °C) with a high yield. The catalyst showed a satisfactory resistance to carbon deposition and sintering deactivation, which is a key point for the intermittent operating conditions of the process. A kinetic model, of the Langmuir-Hinshelwood type, was developed for the first time on a Ni/CZP type catalyst

Smith, Warwick. "War and space in English fiction, 1940-1950." Thesis, University of Sussex, 2016. http://sro.sussex.ac.uk/id/eprint/61022/.
Testo completoAbstract (sommario):
This thesis argues that a preoccupation with space is a characteristic feature of English fiction in the years following the outbreak of the Second World War and, more specifically, that the war's events caused this heightened interest in the spatial. Writing from the 1940s exhibits an anxious perplexity in its spatial descriptions which reveals an underlying philosophical uncertainty; cultural assumptions about spatial categories were destabilised by the war and this transformation left its mark on literature. Writers in London during the war were among civilians shocked by new sensory assaults and dramatic changes to the urban landscape. These material facts exerted pressures on the collective imagination and a major part of the literary response was an urgently-renewed interest in the problematics of space. The primary literary focus here is on Elizabeth Bowen and Henry Green, though work by other writers including Graham Greene, Mervyn Peake and William Sansom is also discussed. I draw on the philosophy of Maurice Merleau-Ponty to illustrate the challenge phenomenological thinking posed to prevailing cultural conceptions of space in this period and to suggest how the war directed writers' attention to the role that embodied perception plays in composing spaces. I also examine how technological change, particularly development of the V2 rocket, shook established spatial thinking and I discuss how conceptual categories such as adjacence, linearity and sequence were further disrupted by the political divisions of post-war Europe. Documentary and diary sources are used to support literary evidence. English fiction changed abruptly and significantly in the 1940s because of a fresh spatial understanding emerging from the war which shaped the culture of the Cold War and the space race. This change demands reassessment of a decade often dismissed in literary history as a dull interlude between temporally-dominated high modernism and a postmodern ‘turn to the spatial.'

Testo completoAbstract (sommario):
The ether was proposed by Enlightenment natural philosophers as an undetectable substance filling the space between the stars, that held them in place and supported the propagation of their light across space. In The Subtle Ether: A Memoir of the Space Between, insights from the history of the ether are threaded through my experience of clearing the family home after the death of my parents, and inform a reflection on ‘spaces between' memories, family members, and between ourselves and the world. This thesis both proposes and practises writing creative nonfiction as a method of first person enquiry that bears a familial resemblance to contemplative traditions, and that can acknowledge and mourn the hiddenness of things by writing into the ‘space between' ourselves and the world. Seeking a new synthesis which meshes experience, emotion, observation, and reflection on the insights of science, I employ mixed modes of lyrical, aesthetic, philosophical and personal inquiry. The central claim of this thesis is that awareness and acceptance of hiddenness as the nature of all things counteracts human hubris. While drawing from the example of continuous, open-ended questioning the scientific search for the ‘ether' offers, this thesis both argues and demonstrates that scientific and analytical methods alone cannot address this hiddenness, and that creative practice can be an effective way to think about and communicate what cannot be directly known. I argue that the desire for complete knowledge is a form of acquisitiveness and control, and that recognising the limited scope of human senses and reason undercuts human centrality and sole agency. Crafting an artwork out of contemplation of that which cannot be directly observed opens a space of reflection in which a paradoxical truth can be held in awareness; that the external reality we observe is other than us but also inseparable from us.

Testo completoAbstract (sommario):
Part 1 of this thesis comprises a biography which, for the first time, places Marion Angus within her historical, family and social context. A version of this was published as the introduction to my edited collection The Singin Lass: Selected Work of Marion Angus (Polygon, 2006). Assumptions made about the poet's activities and attitudes derive from critical reading of archival material: her published 'diaries', letters and prose, as well as her poetry. The appraisal of her work places it within literary contexts. The development of her linguistic awareness of the Scots language is traced and the extent of her commitment to it noted. I conclude that assessment of her work has frequently been affected by erroneous judgements about her lifestyle and that the poetry, which has greater depth than it sometimes is given credit for, illuminates her struggle rather than defines her character. Her strength and resilience, as well as her contribution to Scots literature, should be respected and admired. Part II comprises three extracts from Blackthorn, a novel based on aspects of the life and work of Marion Angus. My starting point was the marked contrast between her earlier prose and her later poetry. This, I believe, reflects an actual family crisis which is central to my narrative. The extracts presented here (dated 1900, 1930 and 1945-46) present a credible alternative to inaccurate assumptions which were made about her life. I explore two actual significant relationships in her life: with a sister who becomes wholly dependent on her, and with a younger friend who looks after her in her final year. In the absence of any firm evidence of lovers, I speculate on other relationships.

Barber, Rosalind. "Writing Marlowe as writing Shakespeare." Thesis, University of Sussex, 2012. http://sro.sussex.ac.uk/id/eprint/39699/.
Testo completoAbstract (sommario):
This thesis consists of two components: a 70,000-word verse novel and a 50,000-word critical component that has arisen out of the research process for that novel. Creative Component: The Marlowe Papers The Marlowe Papers is a full-length verse novel written entirely in iambic pentameter. As with verse novels such as The Golden Gate by Vikram Seth, or The Emperor's Babe by Bernadine Evaristo, its inspiration, derivation, conventions and scope owe more to the prose novel than to the epic poem. Though there is as yet no widely-accepted definition, a verse novel may be distinguished from an epic poem where it consists, as in this case, of numerous discrete poems, each constituting a ‘chapter' of the novel. This conception allows for considerable variations in form and tone that would not be possible in the more cohesive tradition of the epic poem. The Marlowe Papers is a fictional autobiography of Christopher Marlowe based on the idea that he used the pseudonym ‘William Shakespeare' (employing the Stratford merchant as a ‘front'), having faked his own death and fled abroad to escape capital charges for atheism and heresy. The verse novel, written in dramatic scenes, traces his life from his flight on 30 May 1593, through the back-story (starting in 1586) that led to his prosecution, as we similarly track his progress on the Continent and in England until just after James I accedes to the English throne. The poems are a mixture of longer blank verse narratives and smaller, more lyrical poems (including sonnets). Explanatory notes to the poems, and a Dramatis Personae, are included on the advice of my creative supervisor. Critical Component: Writing Marlowe As Writing Shakespeare This part of the thesis explores the relationship between early modern biographies and fiction, questioning certain ‘facts' of Marlovian and Shakespearean biography in the light of the ‘thought experiment' of the verse novel. Marlowe's reputation for violence is reassessed in the light of scholarly doubt about the veracity of the inquest document, and Shakespeare's sonnets are reinterpreted through the lens of the Marlovian theory of Shakespeare authorship. The argument is that orthodox and non-Stratfordian theories might be considered competing paradigms; simply different frameworks through which interpretation of the same data leads to different conclusions. Interdisciplinary influences include Kuhn's philosophy of scientific discovery, post-modern narrativist history, neuroscience, psychology, and quantum physics (in the form of the ‘observer effect'). Data that is either anomalous or inexplicable under the orthodox paradigm is demonstrated to support a Marlovian reading, and the current state of the Shakespeare authorship question is assessed. Certain primary source documents were examined at the Bodleian Library, at the British Library, and at Lambeth Palace Library. Versions of Chapters 2, 3 and 4, written under supervision during this doctorate, have all been published, either as a book chapter or as a journal article, within the last year (Barber, 2009, 2010a, b).

Testo completoAbstract (sommario):
The non-fiction introduction to The Wyvern’s Tale: A Thought Experiment in Bakhtinian Dual Chronotope Occupation documents the evolution of the novel, The Wyvern’s Tale, from the ideas that inspired it to its current incarnation as a full-length novel intended for an adult audience. It comprises an explanation of the novel’s main concept, Bakhtinian dual chronotope occupation, as well as an idea-focused account of the creative-writing process. Detailed in the introduction’s theoretical premise is the relationship between Mikhail Bakhtin’s theories of chronotope and the carnivalesque and the ideal of the divided union in Chalcedonian Christology. This relationship revolves around the state of existing in two time-spaces at once. The novel, The Wyvern’s Tale, explores this dual existence imaginatively using the setting of parallel worlds – the every-day world and a fictional world called Wyvern – as well as a protagonist, who functions in the fictional world as a Christ-figure. Particular thematic emphasis is placed on differing perceptions of truth and reality, and on the transformative power of costumes. The novel’s outcome, dependent on the reader’s decision as to whether dual chronotope occupation is possible or impossible, is respectively either hopeful or tragic. It attempts to reflect the outcome of the life and death of Christ depending on whether his co-existence as God and man was real or imagined.

Testo completoAbstract (sommario):
'The Politics of Place in the Work of Hugh MacDiarmid' argues that there is no fundamental contradiction in MacDiarmid's politics, his Scottish nationalism and international communism issuing in a radical Scottish Republicanism that synchronizes the local and universal, seeking to unify the cultural and political divisions of Scotland. This thesis suggests that MacDiarmid challenges the metropolitan location of culture through a provincialist poetry and politics energized and exasperated by intimate relationship with home. It analyses the connections between MacDiarmid's ideological valorization of difference and the Scottish places from which his politics evolve. Chapter One suggests that modem Scottish cultural politics is still thirled to the imperialistic dualities of the metropolitan Scottish Enlightenment. MacDiarmid's strategic essentialism reasserts an autonomous cultural and political practice that aims to make Scotland whole. The chapter traces MacDiarmid's communism to his defiance of the churchy parochialism of Langholm. Using uncollected newspaper material, Chapters Two and Three illustrate the internationalism of MacDiarmid's localism in Montrose and Whalsay. From examining how engagement with specific places shapes MacDiarmid's politics. Chapter Four returns to analysis of the ideological construction of Scotland. The chapter explores how education has formed ideas of Scotland crucial to its political position and bound up with the specialized Scottish educational system's suppression of a Scottish Republican tradition, whose energies MacDiarmid uncovers and endeavours to release through an autodidactic generalism. Prioritizing this particularity of local culture. Chapter Five argues that the apparent contradictions in the modernist MacDiarmid's politics are best understood in terms of global capitalism's construction of mass culture, a division of labour he opposes through an internationalist poetry of generalist knowledge. This thesis finds theoretical alliance with the internationalism of Marxism and postcolonialism, synthesizing these with an autochthonous critical apparatus, declaring Hugh MacDiarmid a major modem component of a tradition of radical Scottish Republicanism.

Testo completoAbstract (sommario):
In order to counter what I regard as premature and reductive formulations of a 'native' British postmodernism, I identify a specific tendency in contemporary writing which I name the domestic surreal, and which I trace through the poetry of John Ashbery, Frank O'Hara, Roy Fisher, Christopher Middleton, John Ash, Peter Didsbury and Ian McMillan. Through close reading and a comparative approach, I uncover key preoccupations with idiosyncratic perception, shared experience, urban space and poetic play. I also describe a network of allegiances and influence among these writers which reveals the domestic surreal to be one of the contemporary manifestations of an imaginative tradition which stretches back through the Surrealist and Cubist movements to Baudelaire and Rimbaud. For the poets of the domestic surreal, engagement with an aesthetic tradition is inextricably linked with their response to contemporary conditions. Drawing on dialectical and poststructuralist perspectives, I propose that the domestic surreal attempts to resist the constraints of social and aesthetic consensus in Britain and America in the period following the Second World War.

Testo completoAbstract (sommario):
碩士<br>國立成功大學<br>資源工程學系碩博士班<br>95<br>In this study, ZnO varistor doped with Pr6O11, Co3O4, were prepared using traditional solid-state reaction method. In order to decrease the sintering temperature, trace additive, Na2CO3, was added as a sintering aid. The effects of the additive, sintering temperatures, cooling rate on the microstructures and electrical properties of (Pr,Co,Na)-added ZnO ceramics were investigated using XRD, XPS, FESEM, and EPMA.
The observed results can be described as follows:
1. The samples added Na2CO3 possessed better varistor properties.
2. Better varistor properties can be obtained for the samples with much crystalline PrOx phase.
3. For the sample with a slow cooling rate, O2 had a much time to diffuse at grain boundary which resulted in the more adsorption of O2 on the surfaces of the grains. Therefore the superior varistor properties were obtained for the sample with a slow cooling rate compared to the sample with a rapid cooling rate. For the sample with a rapid cooling rate, PrOx phase was observed to be rich in triple point, which resulted in the degradation of varistor properties.
In conclusion, the Pr-doped ZnO ceramics added with Na2CO3, sintered at 1200oC, and at cooling rate of 2oC/min can obtain the best varistor properties: α is 19.6 , Eb is 637.6 V/mm, and IL is 285μA.

碩士<br>國立成功大學<br>資源工程學系碩博士班<br>97<br>In this study, ZnO-Pr6O11-Co3O4 based varistors were prepared using a conventional solid-state reaction and sintering process. The effects of Fe2O3 addition on the microstructure and varistor properties were investigated. PrOx phases were found to locate at grain-boundaries uniformly as proper amount of Fe2O3 was added. This will promote the diffusion and chemisorptions of excess oxygen ions at the grain-boundaries, which enhances the varistor property. The energy barrier heights of the grain-boundary for the samples were measured using impedance spectroscopy and observed that when the Fe2O3 addition concentration was increased to 0.001mol%, the barrier height can be increased, which improved the varistor behavior. However, as the addition concentration of Fe2O3 was increased above 0.005mol%, most PrOx phase(s) were found to locate at the triple points, and form the second phase, ZnFe2O4, which resulted in the deterioration of the varistor property.

Testo completoAbstract (sommario):
This thesis is a biographical study of Sir Philip Gibbs (1877-1962), one of the most famous and widely read English journalists of the first half of the twentieth century. Prior to the outbreak of World War One he reported on the great crises facing Britain domestically and the technological advances which came to symbolise the age. Industrial unrest, Ireland, the suffragette movement, royal births, deaths and coronations, and the sinking of the Titanic were all topics which Gibbs reported on and interpreted for his countrymen. Advances in technology such as the advent of automobiles and the nascent years of aviation in Britain took their place in his articles alongside broader European events such as revolution in Portugal in 1910 and the Balkan War in 1912. Though well regarded prior to 1914, it was his work on the Western Front which was to win him fame and, to a lesser extent; fortune. As one of five official correspondents accredited to the British Army on the Western Front, his articles, which appeared on both sides of the Atlantic, did much to shape civilian attitudes during World War I and its immediate aftermath. Many critics, however, have dismissed Gibbs' work as propaganda and his acceptance of a knighthood in 1920 as little more than a reward for his participation in a conspiracy of silence. His articles, books and correspondence will be used to examine his life, subsequently contributing to an understanding of the role of the war correspondent during the tumultuous war years from 1914 to 1918.
