A evolução da margem continental do sudeste do Brasil tem sido discutida por diversos autores desde meados do século passado até os dias atuais, especialmente no contexto da origem e evolução dos escarpamentos e das bacias tafrogênicas. Buscou-se contribuir com novos dados sobre a evolução da área a partir da aplicação da termocronologia de baixa temperatura (U-Th)/He em apatita, que oferece uma sensibilidade significativa para registrar movimentações tectônicas na crosta superior. Foi possível obter idades em 107 cristais de apatita de 18 amostras do embasamento coletadas no perfil com orientação NW-SE, numa seção entre a Serra da Mantiqueira e o Gráben da Guanabara. As idades corrigidas variam entre 250,1 8,7 Ma e 43,5 1,9 Ma (2 σ) e as não corrigidas entre 174,13 3,03 Ma e 27,07 0,60 Ma (1 σ). O Neocretáceo, o Eocretáceo e o Paleoceno são os principais registros no conjunto de dados, em ordem de importância. No Neocretáceo, o intervalo entre 83,6 e 72,1 Ma (Campaniano) representa o maior destaque nos registros termocronológicos, embora os outros registros (Maastrichtiano e Santoniano) também estejam presentes e sejam importantes. As idades do Neocretáceo destacam a importância dos eventos tectonomagmáticos e soerguimento regional na história térmica dessa área, inclusive com idades (~86 Ma) atribuídas ao contexto de soerguimento da Serra do Mar. As idades do Eocretáceo indicam o registro de eventos térmicos mais antigos, vinculados à evolução pré-rifte. Já os dados do Paleoceno estariam associados ao evento de reativação responsável pela implantação do sistema de riftes continentais (~65 Ma) e as idades do Eoceno, restritas à borda de falha da bacia de Resende (49,7 Ma e 43,5 Ma), à reativação do sistema de riftes nessa área. A dispersão de idades foi interpretada como efeito dos danos de radiação já que muitos grãos apresentam correlação entre idade e concentração de urânio (eU). Os padrões de tempo-temperatura (t-T), definidos a partir dos modelos HeFTy calibrados para o modelo de difusão que considera os efeitos de danos de radiação nos cristais, registraram eventos de resfriamento rápido, os quais mostram correlação direta com episódios de reativação e soerguimento na margem continental e com registros nas bacias continentais e marginais. O padrão de aumento das idades com a elevação, assim como da costa em direção ao interior é observado, mas mostra-se alterado pela ocorrência de idades mais jovens associadas à complexa evolução dessa margem continental com desnivelamentos de blocos vinculados à tectônica pós-rift, numa situação que ressalta a influência dos episódios de reativação. As estimativas de denudação total variam entre 1,2 e 2,8 km. As taxas de erosão variam entre 15,2 e 35,3 m/Ma. A evolução da área indica não apenas a influência de um evento específico mas, possivelmente, uma combinação de episódios que se alternaram e/ou atuaram em conjunto em determinados períodos. Os eventos de reativação mais antigos, combinados com os mais recentes, exibem os seus remanescentes na paisagem (serras da Mantiqueira e do Mar e os grábens e bacias sedimentares) e assumem papel fundamental na evolução da área. Os registros de tais episódios podem ser observados nas histórias térmicas das rochas e nos depósitos correlativos nas bacias sedimentares marginais e intracontinentais. / This doctoral dissertation involves low-temperature thermochronologic investigations to constrain the Mesozoic and Cenozoic tectonic reactivation of the continental margin of southeast Brazil. The study area is located in a segment of the Neoproterozoic Ribeira belt in southeastern Brazil, which occupied a central position in Western Gondwana. Lately, during the Mesozoic and Cenozoic, fault zones related to the development of the continental rifts in southeast Brazil reactivated. Using apatite (U-Th)/He thermochronology (AHe), we have presented the results of analysis on 107 apatite crystals of basement samples collected from a NWSE transect in the Mantiqueira Mountains to the Guanabara Graben, as well as from the NESE transverse faults. The data range from 27.07 0.60 Ma to 174.13 3.03 Ma (1 σ) for uncorrected ages, and from 43.5 1.9 Ma to 250.1 8.7 Ma (2 σ) for corrected ages. The Neo-Cretaceous, Eo-Cretaceous, and Paleocene are the main recorded AHe ages, in order of importance. The Eo-Cretaceous ages indicate the occurrence of older thermal events related to a pre-rifting phase (~121 Ma). The Neo-Cretaceous ages signify the importance of tectonic and magmatic events, and regional uplifting for the thermal history of the study area, including ages related to the Serra do Mar Mountains uplift (~86 Ma). Paleocene ages seem to be related to the reactivation (~65 Ma), which was responsible for the continental rifts in the southeastern Brazil. Finally, the Eocene ages (49.7 Ma and 43.5 Ma), which are from samples restricted to the Resende Basin border faults, indicate a continental rift reactivation. We investigated the age dispersion data, which were interpreted as an effect of radiation damage. Several samples show correlations between apatite (U-Th)/He age and effective U concentration (eU). We have applied HeFTy thermal modeling to obtain timetemperature (t T) paths using a radiation damage diffusion model. Inverse modeling of (U-Th)/He age data suggests rapid cooling episodes for all samples. The main thermal events recorded by the HeFTy models show a direct correlation with the timing of regional tectonic events: reactivation phases, continental margin uplift, and the sedimentary record. Apatite (U-Th)/He ages increase with distance from the coast and with elevation. However, these patterns are discontinued by samples of younger ages as a result of the reactivation process of pre-existing structures in the Brazilian continental margin. The total estimated denudation range from 1.2 to 2.8 km. The erosion rates range from 15.2 to 35.3 m/My. Thus, the multi-episodic thermal events, which led to the formation of important regional tectonic and geomorphological features (Mantiqueira Mountains, Serra do Mar Mountains, grabens, and sedimentary basins), seem to play a fundamental role in the evolution of the Brazilian continental margin. The records can be found in the thermal history of rocks and its correlated deposits in the continental margin.

Neste trabalho estudamos problemas de reação difusão em domínios unidimensionais que surgem de materiais compostos e obtemos resultados comparando os fluxos do problema original e do problema limite quando a difusão fica muito grande em partes do domínio. Provamos que os autovalores e autofunções do operador linear ilimitado associado à equação limite têm a propriedade de Sturm Liouville e provamos que as soluções do problema de reação difusão têm a propriedade do decrescimento do número de zeros ao longo do tempo. Estes resultados são usados para provar que as variedades instável e estável de pontos de equilíbrios são genericamente transversais e que o fluxo no atrator para o problema de reação difusão é genericamente estruturalmente estável. Estes fatos permitem obter a equivalência topológica dos fluxos restritos aos atratores dos problemas original e seu problema limite. / In this work we study some reaction-difusion problems in one dimensional domains that arise from composite materials. We obtain some results comparing the flux of the original problem and the flux of the limit problem when the difusion becomes large on parts of the physical domain. We prove that the eigenvalues and eigenfunctions of the linear unbounded operator associated with the equation have the Sturm Liouville property and also that the solutions of the reaction difusion equation have the property that the zeros do not increase with time. These results are used to obtain that the stable and unstable manifolds of equilibrium points are generically transversal and that the flux on the attractor for the reaction difusion problem is generically structurally stable. Using this we are able to prove the topological equivalence of the fluxs restricted to the attractors of the original and the limit problem.

Undersökningens syfte är att studera dialektutjämning och regionalisering i övre Norrland genom att undersöka fyra markerade dialektala drag – norrländsk förmjukning, oböjd predikativ i pluralis, norrländskt som och he/hä ’det’ – utifrån de utomspråkliga variablerna geografi, ålder och kön. Undersökningen har genomförts genom att lyssna på intervjuer av fyra informanter per ort från följande fem orter: Piteå i Norrbotten, Burträsk i Västerbotten, Sorsele i Lappland, Aspås i Jämtland och Anundsjö i Ångermanland. Materialet är inspelat för projektet SweDia 2000. Studien visar att norrländsk förmjukning finns på alla orter men används i huvudsak av äldre. I inlandet (Aspås och Sorsele) har man kategoriskt dialektvarianten medan man vid kusten växlar i sitt bruk. Oböjd predikativ i pluralis är vanligt på alla orter och står starkt emot eventuell utjämning. Norrländskt som används på alla orter och i högre grad av yngre än äldre, de yngre har även mer frekvent bruk. He/hä ’det’ finns hos nästan alla informanter på de nordligare orterna, däremot inte alls i Aspås och Anundsjö. Draget är starkt men används mer frekvent av de äldre. Dialektutjämning och regionalisering av dialekter sker i övre Norrland och olika drag klarar sig olika bra; norrländsk förmjukning ligger i riskzonen för att försvinna medan de övriga dragen står starka.

La zone de déformation compressive des Brooks Range et des British-Barn située entre l’Alaska (Etats-Unis) et la région du Nord Yukon (Canada), en position arrière-arc, se développe dans un contexte cinématique et géodynamique depuis longtemps débattu. L’histoire tectonique du bloc continental Arctique d’Alaska, situé dans l’avant-pays de Brooks Range, est diversement interprétée dans les reconstructions de l’ouverture du bassin canadien. La chaîne de Brooks se développe à partir du Crétacé inférieur et sa mise en place se poursuit au Cénozoïque. Mieux contraindre son histoire d’exhumation, en relation avec le raccourcissement est essentiel dans cette région arctique où la cinématique des plaques, associée à l’ouverture du bassin canadien au Nord, fait l'objet de nombreux modèles géodynamiques controversés. La relation avec la subduction active Pacifique au Sud et les grands décrochements en arrière de la subduction fait de cette chaîne, en position arrière arc, une zone-clef pour affiner les reconstructions géodynamiques régionales et notre compréhension des processus orogéniques. Si le lien n'est pas établi entre la déformation mise en jeu dans cette subduction au Mésozoïque et la déformation dans la chaîne de Books, ce lien est en revanche assez bien documenté à l'heure actuelle. Il est donc légitime d'appréhender les événements sud-alaskans dans l'étude de cette chaîne de Brooks. La croissance de la chaîne au Cénozoïque est également mal comprise. Or, il s’agit d’un exemple quasi-unique de chaîne en milieu arctique active durant le Cénozoïque et qui a donc potentiellement enregistré des bouleversements climatiques majeurs, en l'occurrence depuis l‘optimum climatique à la transition Paléocène-Eocène, le refroidissement Oligocène jusqu’à la mise en place de glaciers et de la calotte nord-américaine au Quaternaire. Cet orogène est donc clef pour étudier voire quantifier l'impact du climat sur la construction topographique nord-alaskane. Ce travail a combiné une étude thermochronométrique basse-température multidatation (FT, (U-Th)/He) dans les massifs granitiques et dans les sédiments, qui ont fait l'objet de modélisation thermo-cinématiques via Pecube, dans le but de contraindre la construction orogénique depuis 100 Ma jusqu’à l’actuel. En parallèle, une approche structurale de terrain (Nord Yukon et Brooks Range) et l'analyse de données de subsurface ont été menées. Les données thermochronologiques, couplées à des analyses thermométriques RSCM et de la modélisation thermique soulignent la mise en place de reliefs au Crétacé supérieur avec une exhumation modérée (0.2 km/Ma) qui se poursuit jusqu'à la fin de l'Eocène, où les taux d'exhumation dans les chaînes de Brooks et British-Barn sont clairemement orogéniques (1.25-1.29km/Ma), et associés à la migration de la déformation vers les bassins adjacents. Ce travail souligne une migration de la déformation du SO vers le NE. Dans les deux segments de la chaîne un événement d'exhumation distinct est identifié à l'Oligocène : celui-ci est clairement associé dans la partie interne de la chaîne de Brooks à la mise en place hors-séquence d'un duplex crustal ; et associé à la migration de la déformation compressive en mer au large de la chaîne de British-Barn. Si le calendrier tectonique est semblable dans ces deux zones d'étude, il existe une différence majeure dans le style de déformation entre ces deux régions. Le front de déformation semble beaucoup plus éloigné de la chaîne et les failles beaucoup plus espacées dans la partie canadienne, éloignement et espacement probablement liés à l’épaisseur de sédiments syn-sédimentaires présents dans le bassin... / The kinematics and geodynamics associated with the compressional deformation in the Brooks Range and British-Barn Mountains, respectively in Alaska (USA) and North Yukon (Canada), in a back-arc setting has long been debated. In particular, the tectonic history of the Arctic Alaska continental block located in the foreland of the Brooks Range has been diversely interpreted in the plate reconstructions proposed for the Canadian basin. The Brooks Range mountain chain develops from the Lower Cretaceous to the Cenozoic. Constraining its exhumational history and its link with shortening evolution is essential in this arctic area where plate tectonics, associated to the Canadian basin opening in the North, has led to controversial geodynamic models. Tectonic coupling with the active Pacific subduction in the south as well as major seismogenic strike-slip faulting make this orogen a key area where to refine the regional plate reconstructions and understanding of orogenic processes. The Cenozoic evolution of the Brooks Mountains is poorly understood although it is a nearly unique example of arctic orogen, which have potentially recorded major climate changes like Paleocene-Eocene Thermal Maximum, the Oligocene cooling and Quaternary glaciations. This orogen is a key to study and quantify the climate impact on the north-alaskan topographic growth. This study combined low-temperature thermochronometry (FT, U-Th/He) on granitic and sedimentary rocks, which were thermo-kinematically modeled using Pecube in order to define the orogenic evolution of this arctic region since 100 Ma. In parallel, a field-based structural study (North Yukon and Brooks Range) was combined with the analysis of subsurface data. Thermochronological data, coupled to thermometric RSCM analyses and thermal modeling first define a slow exhumation period (0.2 km/Ma) from Upper Cretaceous up to the Eocene. With the Eocene, exhumation rates drastically increased to reach 1.25-1.29km/Ma as the deformation also migrates from SW toward NE. In both alaskan and canadian parts of mountains ranges a clear Oligocene exhumational event is identified. This event is linked to out-of-sequence crustal duplexing in the internal part of the range in the Brooks Range, contemporaneous with the propagation of deformation offshore, along British and Barn Mountains...

This study focuses on the University of the Highlands and Islands (UHI) modelled on a federal, collegiate university based on a number of existing and geographically dispersed Further Education (FE) colleges and research institutions. The inclusion of FE colleges and their geographical dispersal distinguishes it from most mainstream institutions. The UHI was heralded by its advocates as a distinctively radical enterprise designed to meet the fast-moving challenges of the twenty-first century by embracing new technologies and overcoming geographical barriers. After attaining Higher Education (HE) status in 2001, the policy goal of fostering a research culture emerged as a prominent concern for the UHI. This study explores the policy drive to foster such a research culture, focusing on the period from 2003 to 2008. The study was informed by a constructivist grounded theory methodological approach and the data gathering included twenty-six semi-structured interviews to ascertain how this policy drive was received within the UHI partners. The study found that a unified research culture was not perceived to have embedded throughout the partners, with the exception of one or two research institutions where it can be said to have pre-existed. Against this backdrop, the study identified emerging discourses encapsulating how the policy drive was perceived by a wide spectrum of different actors throughout the UHI. Two different types of performativity discourses proved to be central in shaping the policy aspiration, namely a ‘RAE performativity discourse’ and a ‘Further Education (FE) performativity discourse’. Both discourses can be seen to have influenced the trajectory of research expansionist policy within the UHI by setting up a normative space privileging certain identities, subjectivities and associated actions at the expense of others. In highlighting both the structural and socio-cultural barriers to the policy of promoting research, the study aims to contribute to wider debates on institutional policies for building research capacity in a dual sector/hybrid institutional setting. In terms of offering direct benefits to the UHI, by analysing the different sort of assumptions and realities that shape the meaning of a research culture within the UHI, this study may help inform future policy making on research expansion within UHI partners. The study concludes by making a number of practical recommendations which the author believes will help move research from the periphery to a more central stage within the UHI partners.
