Full textAbstract:
L’histoire et la transformation d’un paysage forestier d’une région côtière du centre-nord du Labrador (Canada) ont été étudiées dans cette recherche par l’entremise d’une approche multidisciplinaire intégrant des méthodes associées aux sciences naturelles et aux sciences sociales. Cette étude visait plus précisément à : 1) documenter l’histoire de la végétation durant l’Holocène moyen et récent en relation avec les changements climatiques et les activités humaines; 2) à déceler les impacts des activités humaines sur la composition et la structure de la forêt et 3) à mettre en évidence l’importance économique et culturelle de cette dernière pour une communauté inuite. Les résultats des analyses polliniques et macrofossiles ont permis de retracer les changements ayant affecté les communautés végétales sur une longue échelle temporelle. Ces résultats représentent une contribution importante à l’étude de la paléoécologie terrestre du Labrador, en détaillant l’histoire de la végétation sur près de 5000 ans et en la corrélant à un cadre climatique régional. En particulier, des changements dans les assemblages végétaux ont montré le déclin de l’épinette et l’abondance accrue du mélèze à la fin du 18e siècle, ainsi que la paludification du milieu. Ces changements écologiques sont survenus au moment de l’établissement des Européens sur la côte du Labrador, et seraient expliqués par l’augmentation de la demande locale pour le bois comme matériel de construction et de chauffage. Les résultats dendroécologiques ont, de leur côté, documenté l’historique et les impacts de la coupe de bois sur les forêts durant le 20e siècle. La récolte de bois a affecté la structure d’âge de la forêt, qui est caractérisée par l’absence de vieux arbres et de bois mort. Des épisodes de détentes de croissance ont été enregistrés par les arbres survivants, témoignant du caractère chronique de la coupe. Cette dernière s’est pratiquée de manière plus intensive près de la communauté, mais a aussi été effectuée autour d’anciens établissements en périphérie du village. Les activités de coupe ont été analysées dans leur contexte historique et culturel grâce au volet ethnographique de l’étude. Ainsi, des entrevues conduites avec des experts locaux (chasseurs, aînés, décideurs) ont permis de documenter les patrons d’utilisation du bois et la place de cette ressource dans l’économie de subsistance des Inuit de Nain. Le bois constitue encore aujourd’hui une ressource clé pour les résidents, qui le récoltent principalement durant l’hiver pour leurs besoins de chauffage. Cette recherche amène une perspective nouvelle sur l’écologie historique de la région de Nain, en faisant ressortir les liens entre les changements écologiques et les changements socio-économiques et la manière dont ils ont transformé le paysage forestier.In this research, we used a multidisciplinary research approach that included methods from both the social and natural sciences to study the history and transformation of a forest landscape on the central-north coast of Labrador (Canada). This study aimed more precisely at: 1) documenting the history and vegetation during the middle and late Holocene in relation to climate change and human activities; 2) identifying the impacts of human land use on the composition and structure of the forest and 3) highlighting the economic and cultural importance of the forest for an Inuit community. The results obtained through pollen and plant remain analysis allowed for the reconstruction of plant community changes on a wide temporal scale. These results represent an important contribution to terrestrial paleoecology in Labrador, by providing a 5000 year record of vegetation history and correlating it with a regional climatic context. In particular, changes in plant assemblages showed the decline of spruce at the end of the 18th century, which was soon followed by the increased presence of larch. This pattern appears to be related to the paludification of the milieu. These ecological changes occurred at the time of European settlement on the Labrador coast and can be explained by the increase in the demand for local wood for fuel and lumber. Furthermore, dendroecological results documented the history and impacts of wood harvesting during the 20th century. Wood cutting altered the forest age structure, which is characterised by the absence of old and dead trees. Growth release events were recorded by surviving trees, testifying of the chronic nature of cutting activities. The latter were more intensive near the community, but were also taking place around former small establishments in the region. Wood harvesting practices were analysed in their historical and cultural context through the ethnographic component of the study. Thus, interviews conducted with local experts provided insight on wood use patterns and the place of this resource in the subsistence economy of the Inuit of Nain. Wood is still today a key resource for residents, who harvest it mainly during winter for their heating needs. This research contributes a new perspective to the historical ecology of the Nain region by emphasizing the connections between ecological and socio-economic changes and the way they transformed the forest landscape.

Full textAbstract:
Les mutualismes sont omniprésents dans la nature, mais les conflits d'intérêts qui opposent les partenaires peuvent rendre ces interactions instables. Certaines études théoriques issues de la théorie des jeux ont souligné l'importance du processus de la rencontre des partenaires pour la stabilité évolutive des mutualismes. Le but de cette étude était de comprendre, par une approche expérimentale, comment les conflits d'intérêts entre partenaires et l'émission des signaux facilitant leur rencontre à chaque génération agissent sur la stabilité des mutualismes à transmission horizontale. Nous avons étudié le mutualisme entre le palmier Chamaerops humilis et son pollinisateur spécifique Derelomus chamaeropsis, qui se reproduit dans les inflorescences de sa plante hôte. Dans ce mutualisme, les plantes femelles sont « tricheuses» ; elles détruisent les oeufs des pollinisateurs, induisant ainsi un phénomène de pollinisation par tromperie, très coûteux pour le pollinisateur, et qui constitue une source d'instabilité pour l'interaction. L'étude du mode d'attraction des pollinisateurs chez C. Humilis a révélé un système inconnu jusqu'alors chez les angiospermes ; les pollinisateurs sont attirés par des composés volatils émis par les feuilles, et non par les fleurs. Une première étude comparée suggère que ce mode d'attraction pourrait avoir évolué dans des conditions écologiques particulières chez quelques espèces de palmiers. Par ailleurs, le signal olfactif présente un dimorphisme sexuel sur la quantité de composés volatils. Ce dimorphisme conduit les pollinisateurs à rencontrer plus fréquemment le signal émis par les plantes mâles et à les visiter plus souvent. Toutefois, nous avons montré que la composition chimique du signal était extrêmement variable entre individus. Cette variabilité élude toute possibilité de différencier qualitativement les signaux mâles des signaux femelles et empêche l'évolution d'un comportement de choix actif chez le pollinisateur. Notre étude empirique va à l'encontre des prédictions théoriques et montre que l'incapacité d'un partenaire à « punir» les « tricheurs» peut paradoxalement stabiliser un mutualisme. Ceci s'explique en partie par le fait qu'une espèce mutualiste n'est pas forcément un ensemble homogène d'individus. Ici, les divergences d'intérêts entre plantes mâles et femelles non seulement caractérisent les conflits d'intérêts avec le troisième partenaire (le pollinisateur), mais déterminent également la dynamique évolutive de l'interactionMutualisms are ubiquitous in nature, but according to current theory the conflicts of interest between mutualists should make these interactions unstable. Studies based on game theory have underlined the importance of the process of partner encounter in determining the evolutionary stability of mutualisms. The aim of this study was to understand, using an experimental approach, how the conflicts of interest between partners in a horizontally transmitted mutualism, and the emission of signals facilitating partner encounter in each new generation, interact to affect the evolutionary stability of the mutualism. We studied the mutualism between the paIm Chamaerops humilis and its specifie pollinator Oere/omus chamaeropsis, which reproduces inside the inflorescences of its host plant. Ln this mutualism, female plants are "cheaters"; they kill the eggs of their pollinator, leading to a phenomenon of pollination by deceit, imposing high costs on the pollinator and constituting a potential source of instability for the interaction. Our study of the mode of pollinator attraction by C. Humilis has revealed a unique system, previously unknown in angiosperms. The pollinators are attracted by volatile compounds emitted by leaves, and not by flowers. A preliminary comparative study suggests that this mode of attraction may have evolved more than once in palms, under particular ecological conditions. Furthermore, the chemical signal released shows sexual dimorphism in the total quantities of volatile compounds emitted by plants. This difference leads the pollinator to encounter male plants more frequently and to visit them more often. However, we showed that the chemical composition of the signal was extremely variable among individuals, excluding any possibility of qualitative distinction between signals emitted by male and female plants and preventing the evolution of an active choice behaviour by the pollinator. Our results contradict predictions from theory and show that the inability of a partner to "punish cheaters" can paradoxically stabilise a mutualism. The paradox is partly explained by the fact that the population of a mutualist is not necessarily a homogeneous set of individuals. In this system, the divergence of interests between male and female plants not only conditions the conflict of interests with the third partner (the pollinator), but also determines the evolutionary dynamics of the interaction

La fin du 18e siècle était une période dynamique au Labrador. À cette époque, le phénomène climatique nommé le Petit Âge glaciaire affectait grandement l'étendue de la banquise côtière. L'arrivée des missionnaires et des objets européens enclencha une réorganisation des rôles sociaux chez les Inuits. L'établissement hivernal d'Ikkeghasarsuk, connu sous le code Borden HdCg-23 et le nom de site officiel Koliktalik-6, est composé principalement de deux maisons semi-souterraines construites avant 1776 sur un site dorsétien. La présente étude explore les stratégies d'occupation du territoire par l'analyse des restes fauniques de ces deux maisons. Les espèces de phoques chassées et leurs niches écologiques indiquent que les occupants du site exploitaient surtout les phoques présents dans les eaux libres de glace à l'automne, les phoques annelés au sina l'hiver et les phoques annelés sur la banquise côtière au printemps. Le site d'Ikkeghasarsuk, placé sur une île dénudée et balayée par le vent, aurait permis d'avoir un accès privilégié aux ressources marines diverses, peu importe les conditions climatiques.The late 18th century was a particularly dynamic era on the northern Labrador coast. The climatic phenomenon known as the Little Ice Age created highly variable ice conditions. Missionaries settling on the northern coast and the influx of European goods set off a reorganisation of Inuit social roles. Ikkeghasarsuk, known as HdCg-23 and Koliktalik-6, is mainly composed of two sod houses built before 1776 over a Dorset site. This study focuses on regional occupation strategies through a zooarchaeological analysis of faunal materials sampled from middens associated to the two houses. This indicates that the hunters based at Ikkeghasarsuk exploited open water seals in the fall and ringed seals at the sina in the winter and on landfast ice in the spring. The site, while located on a barren and windy island, would have allowed easy access to marine resources regardless of climatic conditions.

Peu d’études ont porté sur le rhizome du bleuet nain et les effets des pratiques culturales sur ce dernier sont inconnus. Trois expériences ont été réalisées. La première visait à vérifier l’influence d’une fertilisation sur le rhizome et son développement en fonction de l’âge de la bleuetière et de l’étape du cycle de culture (végétation ou récolte) à quatre moments au cours de la saison. Les deux autres ont permis d’examiner l’impact du sectionnement des rhizomes et d’une taille effectuée à différentes hauteurs en bleuetières récemment aménagées. La fertilisation a favorisé le développement de nouveaux rhizomes et la formation d’un plus grand nombre de bourgeons, mais n’a pas influencé leurs teneurs en sucres. Le sectionnement a activé un grand nombre de bourgeons et le potentiel de régénération des segments est lié à leur diamètre et leur longueur. Une taille à moins de 1 cm du sol a stimulé davantage la formation de tiges à partir du rhizome.There have been very few studies on the rhizome of the lowbush blueberry, and as such, the effects of cultural practices on that specific rhizome are unknown. Three experiments have been conducted. The first one dealt with the effects of fertilization on the rhizome and its development depending on the age of the blueberry field and the cultural cycle phase (vegetation or harvest) at four different times during the season. The second and the third experiments dealt with the impact of rhizome severing and stem pruning at different heights in newly planned blueberry fields and their density. Fertilization fostered the development of new rhizomes with a higher number of buds, but did not change their sugar content. The severing stimulated a lot of buds, and it was noticed that the segments’ regeneration potential was linked to their diameter and length. Pruning at less than 1 cm from the ground boosted stemming from the rhizome.

Ces diverses images s'actualisent dans l'espace du cinema, justifiant les utilisations malefiques ou benefiques de ce personnage. Cependant, le corps-taille, ainsi nomme car ce corps n'est defini que par la taille, bouleverse manifestement la narration comme la mise en scene. L'intrusion du nain pose alors les problemes de la taille, du temps et de l'espace dans un lieu revelateur, le cinema, qui comprend aussi ces memes enjeux. Bien plus, ce corps, constitue image par le regard, est devenu une fiction malgre lui. Le spectateur projette angoisses ou desirs inconscients, delivre sur son corps des recits et des mythes, esperant par la combler la difference. Le nain est alors une << chair-fiction >>. Ancienne image de cinema dans les fetes foraines, a la cour de france, il devaste montage et mise en scene dans le septieme art. Sa specificite s'actualise dans la specificite du cinema.

Resumo: O objetivo do presente estudo foi analisar a seletividade do composto NAIN para os subtipos de adrenoceptores beta-1 e beta-2. Com esta finalidade, avaliamos as respostas cronotrópica ( FC ) "in vivo" e "in vitro" e a resposta pressórica (PA) "in vivo". Os experimentos "in vivo" foram realizados em ratos cateterizados e conscientes submetidos a doses crescentes de NAIN (0.003 a 1.0 ug/100g) administradas por via endovenosa. Os resultados obtidos foram comparados aos do isoproterenol (ISO). Observamos que o NAIN não induz aumento significativo da FC, e induz redução da PA apenas em resposta à sua menor dose (0,003 ug/100g). Enquanto que o ISO, tal como esperado, determina um aumento da FC e redução da PA de maneira dose dependente. Os experimentos "in vitro" conduzidos em átrios direitos isolados de ratos e cobaias sugerem que o NAIN é um agonista não seletivo de adrenoceptores beta cardíacos. A reta da regressão de Schild obtida para o metoprolol, em concentrações seletivas para os adrenoceptores beta-1 em átrios de cobaia, usando o NAIN como agonista, apresentou coeficiente angular diferente da unidade, indicando que o efeito cronotrópico positivo do NAIN, nesta proparação, deve-se à ativação de ambos os subtipos de adrenoceptores.
Abstract: The selectivity of NAIN as a beta-adrenoceptor agonist was studied "in vivo" and "in vitro". The effects of the drug on arterial pressure and heart rate in conscious rats were compared with those obtained using isoproterenol. The pA2 value, obtained in isolated guinea-pig right atria for propranolol was compared to that obtained for metoprolol. The results from guinea-pig atrial preparations strongly suggest that NAIN activates both adrenoceptor subtypes since metoprolol was incapable of competitively blocking the chronotropic effect of NAIN (Schild Plot slope different from unity). These results are supported by the increase in heart rate observed in the rat right atrial preparation. In contrast, the experiments in conscious rats did not provide any significant evidence of receptor subtype activation, or was there a clear-cut dose-response relationship. The latter phenomenon may reflect, at least in part, the discrete bioavailability of the drug.

Full textAbstract:
« Il était une fois »… un professeur autrichien, Theodor Vernaleken, qui souhaitait diffuser les récits populaires et coutumes traditionnelles des régions alpines. Ce « Grimm autrichien » les restitue si fidèlement dans ses Contes des Alpes pour les enfants et le foyer et ses Légendes des Alpes qu’il adopte la forme dialectale. Pédagogue émérite, il annote ses récits de nombreuses remarques explicatives rendant ainsi ces témoignages accessibles. Le conte est un récit se déroulant « autrefois » « dans une contrée lointaine ». Les êtres fantastiques surgissent tout naturellement au moment opportun, pour permettre ou empêcher le héros de vivre heureux et d’avoir beaucoup d’enfants. Pour sa part, la légende vise à être crue. Dans ces contes et légendes, les habitants ou un membre de la communauté villageoise ont vu de leurs propres yeux, dans leur village, des êtres surnaturels. Ils nous racontent leur étonnement, leur peur découlant de leur confrontation à cet autre monde peuplé de démons. C’est ainsi qu’apparaissent des homoncules, des géants, des dragons et autres animaux fantastiques, qui parlent, se transforment, etc. L’homme est également confronté à des protagonistes démonologiques tels que sorcières, diables et revenants. Celui qui a transgressé les interdits ne pourra échapper à son destin, tel est le message de ces récits exemplaires et instructifs. Jusqu’à présent, aucune étude exhaustive, ni classification de ce genre littéraire n’a été réalisée. Ainsi, cette étude analysera, par une approche comparative, les récits démonologiques à travers l’étude des êtres fantastiques des textes rassemblés par Theodor Vernaleken“Once upon a time”… an austrian professor, Theodor Vernaleken, wanted to spread popular stories and traditional uses from the alpine areas. This “Austrian Grimm” restores them in his books Tales From the Alps for children and home and Legends from the Alps so faithfully that he writes them in dialect form. Highly skilled teacher, he writes lots of explicative notes on his stories making them understandable. A tale is a story, which takes place “a long time ago” “in a far faraway country”. Fantastic creatures appear quite naturally at the right time to allow the heroes to live happy and have lots of children or to prevent it to happen. As for it the legend aims to be believed. In these tales and legends inhabitants or a member of the village community have really seen supernatural creatures in their village. They tell us about their amazement, their fear from the confrontation with this other world populated with daemons. So dwarfs, giants, drakes and other fantastic animals and so on appear, speak and are completely transformed. Humans are also confronting demonologic protagonists such as witches, devils and ghosts. Who transgresses the interdicts cannot escape from his fate. That is the message of these exemplary and instructive stories. Up to now, no exhaustive survey or classification of this literary genre has been carried out. So, this work will analyse demonologic stories in a comparative way through the study of fantastic creatures in texts gathered by Theodor Vernaleken

TESIS PARA OPTAR AL GRADO DE MAGÍSTER EN ADMINISTRACIÓN
Nayadeth Sepúlveda Vigué [Parte I], José Ricardo Ibarra Castro [Parte II]Actualmente ha habido un incremento en la oferta de vuelos, ya sea por menores precios o por mayor oferta de líneas aéreas. Y junto con esto, también se puede observar que los pasajeros cuentan con un tiempo de espera ocioso antes de abordar su vuelo, el cual pueden utilizar de varias maneras. Pero en el Aeropuerto de Santiago no está presente la oferta de un servicio de Manicure, que es la esencia de este negocio, denominado Air Nails. Las razones del por qué se ha elegido realizar este emprendimiento se fundamentan en lo siguiente: El servicio de Manicure constituye un negocio innovador, único, ya que actualmente no hay competidores directos, y distintivo en el Aeropuerto de Santiago de Chile. El volumen de pasajeros anuales del Aeropuerto, que actualmente alcanza 18 millones y que se espera que para su ampliación al 2020 esta cifra crezca a 30 millones al año. La principal ventaja competitiva y comparativa de Air Nails es que se tiene el permiso para operar y “La Exclusividad” en el aeropuerto, por lo menos hasta los cinco primeros años de duración del contrato. Considerando la evaluación financiera, se puede ver que es un negocio rentable y atractivo, dadas las condiciones de la industria, la baja penetración del mercado, el bajo nivel de riesgo y los flujos futuros estimados: El monto de inversión inicial de $84.915.405 es razonable y aportado en su totalidad por los socios. La evaluación presenta un VAN positivo de $86.392.717 y un Payback de 3,3 años o 33 meses, considerando que el año 1 solo considera 5 meses. El EBITDA a partir del segundo año de operación es de $35.999.943, y supera el resultado negativo del año 1, que sólo considera 5 meses de operación. Los siguientes años, este valor va en aumento sostenido.

The aforementioned detector system, due to the size of the active volume as well as its specific form (well) possess the highest detection efficiency compared with all gammaspectrometric systems currently in use at the Laboratory of Nuclear Physics, Faculty of Science, University of Novi Sad and beyond. Gammaspectroscopy is a non-destructive method that can be applied for the determination of low activity samples without chemical preparation and is the gold standard in radioecological studies, environmental control and so on.The detector systems high efficiency, which was during the preparation of doctoral dissertation put into operation, allows significant reduction in measurement time as well as lowering the minimum detectable activity. In this way, the Laboratory for Nuclear Physics get detection system which can be used for the analysis of samples of low activity for scientific purposes as well as for routine control of environmental samples.For use well type 9``x 9`` NaI (Tl) spectrometer in routine measurements of radiological samples of low activity, there was a need adequate calibration of the detector efficiency of the system with various forms of sample matrix thus the results of measurements made comparable with accredited semiconductor systems in Laboratory for Nuclear physics.

Full textAbstract:
Denna uppsats handlar om namn och referens. Syftet är att jämföra Gareth Evans’ kausalteorimed Imogen Dickies. Efter en introduktion kommer jag att undersöka hur teorierna förklararhur en talare introduceras in i en namnanavändningspraxis, att objekt kan byta namn och attobjekt kan ha en oklar referens.Evans menar att egennamn får sin referens genom en grupp producenter för att sedananvändas i en namnanvändningspraxis i samhället. Producenterna är garanter för att namnetrefererar till objektet, eftersom de kan identifiera objektet såsom känt som NN. En gruppkonsumenter ansluter till producenternas namnanvändningspraxis, med avsikten att refereratill objektet som NN. Så länge som objektet är den dominanta källan till talarens tankar, hadedessa tankar objektet som sin referent.Dickie visar att Evans’ teori har svårt att förklara vissa exempel och föreslår en förbättradteori. Hon definierar principen om referens och berättigande, som, tillsammans med hjärnansbehov att representera, bildar en ram för referensfixering. Dickie identifierar tre grupper avnamnanvändare och visar att de fixerar sin referens på olika sätt. Producenterna genomutpekande, de parasitiska konsumenterna till vemhelst resten av gruppen talar om, och dedeltagande konsumenterna genom en försiktig upptagning av strömmar av vittnesbörd somsammanstrålar på objektet. Så länge som denna upptagning styrs av objektet, handlartrosuppfattningarna om objektet, och fixerar på så sätt referens.Jag hävdar att Dickies teori är en förbättring, även om det finns problem som behöver lösas.This essay is about proper names and reference. Its purpose is to compare Gareth Evans’causal theory with Imogen Dickie’s theory of fixing reference. After an introduction, I willexamine how the theories deal with a speaker’s introduction into a proper-name-usingpractise, that objects can change their names and that an object can have an unclear reference.Evans claims that a proper name gets its reference to an object via a group of producers andthen it is used in a proper-name-using practise in the community. The producers guarantee thereference of the name to the object, because they can identify the object known as NN. Agroup of consumers picks up the name-using practise from the producers, with the intention torefer to the object as NN. As long as the object is the dominant source of the speaker’sthoughts, these thoughts have the object as their referent.Dickie shows that Evans’ theory has difficulties in explaining certain examples and proposesan improved theory. She defines the principle of reference and justification which, combinedwith the mind’s need to represent, gives a framework for reference-fixing. Dickie identifiesthree groups of name-users and shows that they fix their reference in different ways. Theproducers by demonstration, the parasitic consumers to whoever the rest of the group istalking about, and the participating consumers by a careful uptake from testimony streamsthat converge on the object. As long as this uptake is governed by the object, the body ofbeliefs is about the object, thus fixing reference.I argue that Dickie’s theory is an improvement, although there are some problems that need tobe resolved.

Full textAbstract:
Em junho de 1955, o periódico inglês The Architectural Review publicou uma edição especial chamada Outrage escrita pelo jovem crítico Ian Douglas Nairn (1930-1983) que teve um profundo impacto no debate sobre a reconstrução do pós-guerra. Essa dissertação analisa a trajetória intelectual e profissional de Ian Nairn e seu envolvimento com um modelo de intervenção ambiental e metodologia de projeto urbano articulada pela The Architectural Review a partir de 1947 e conhecida com o nome de Townscape. Ao explorar o contexto histórico e cultural na Grã-Bretanha do pós-guerra e o clima intelectual específico na Review essa pesquisa pretende avaliar a esquecida contribuição de Nairn em promover o ideário Townscape na Grã-Bretanha e no exterior. Também pretende demonstrar como esse ideário determinou sua visão e esteve presentes não apenas em seu trabalho para a Review mas também em uma diversa gama de mídia. Não só sua visão era profundamente influenciada pelo ideário Townscape mas podemos afirmar que ele acrescentou ao Townscape algo muito pessoal e essa marca foi importante para a visibilidade dos princípios Townscape e portanto para uma ampla penetração dos mesmos.In June 1955, the English periodical The Architectural Review published a special edition called Outrage by young critic Ian Douglas Nairn (1930-1983), which had a profound impact on the post-war reconstruction debate. This dissertation analyzes Ian Nairn\'s professional and intellectual trajectory, and his involvement with a model of environmental intervention and urban design methodology articulated by the Architectural Review beginning in 1947 and known under the rubric of Townscape. By exploring the historical and cultural context of post-war Great Britain, as well as the specific cultural climate within the Review, this study aims to assess Nairn\'s largely forgotten contribution in promoting Townscape ideals both in Great Britain and abroad. It also aims to demonstrate how these ideals determined his vision and were present not only in his work at the Review but also across a wide range of media. In addition, we also assert that Nairn added his own unique signature, which was key to the increasing visibility of Townscape ideals and therefore to their dissemination.

Full textAbstract:
Detection of diseases in an early stage is very important since it can make the treatment of patients easier, safer and more ecient. For the detection of rheumatic diseases, and even prediction of tendencies towards such diseases, capillaroscopy is becoming an increasingly recognized method. Nail-fold capillaroscopy is a non-invasive imaging technique that is used for analysis of microcirculation abnormalities that may lead todisease like systematic sclerosis, Reynauds phenomenon and others. The main goal of this master thesis project is to provide new tools and techniques for the analysis of capillaroscopy images from the nail-fold area. Image processing and machine learning techniques are applied to images obtained by digital microscopes, like Mediscope as produced by Optilia Instruments AB, Sollentuna. This thesis oers a novel way for segmentation of capillaries from images as well as (semi)automatic capillary width calculation and automatic annotation of capillaries. These tools provide new insights into the structure of capillaries and also reduce the time required for measurement/annotation of capillaries.

Full textAbstract:
Basic information about nail behaviour, under passive and especially iontophoretic condition, lacks in the literature. Thus, this thesis aims to fill gaps in the nail understanding by studying the potential and feasibility of the application of iontophoresis to human nail. The iontophoretic and passive delivery of Sodium Fluorescein (SF) and Nile Blue Chloride (NBC) were studied, in vitro, in order to determine their pathways as well as their depth and uniformity of penetration into the nail. The permselective properties of the nail were investigated by characterizing the contribution of electroosmosis, using mannitol as a marker, and by studying the flux of two inorganic cations, sodium and lithium, during in vitro experiments. Finally, the feasibility of transungual iontophoresis and the extraction of sodium and chloride ions from the body through the nail plate were performed on a group of human volunteers. Iontophoresis led the fluorescent markers slightly deeper into the nail plate than passive diffusion. The delivery of the bianion and of the cation was not different. Both compounds mainly penetrated the nail via the transcellular pathway. Electroosmosis resulted only in a slight enhancement of the mannitol fluxes compared to passive diffusion and the fluxes presented high variability, especially at pH 7.4 and when the current was applied in the anode-to-cathode direction. The delivery of the two inorganic cations was significantly higher at pH 7.0 than at pH 4.0 and supported that nails hold a negative charge at physiological pH. Ions were easily extractable through the nail plate during in vivo iontophoresis and all volunteers' feedbacks supported iontophoresis as an acceptable technique. This thesis demonstrated the feasibility and potential of in vivo transungual iontophoresis.

Full textAbstract:
Syftet med denna studie är att analysera hur manlig och kvinnlig makt konstrueras i fantasyromanen Vindens namn. Ett intersektionellt perspektiv på maktkonstruktioner utgör studiens teoretiska och metodologiska utgångspunkt, med fokus på hur genus-, klass- och etnicitetsaspekter samvarierar i romankaraktärernas maktpositioner. Målet med studien är också att diskutera romanens möjligheter i svenskämnets värdegrundsarbete. Vidare belyses komplexa mönster för maktkonstruktion i romanen som lärare bör vara uppmärksamma på om man använder den som utgångspunkt för klassrumsdiskussioner om hur makt skapas i såväl romanen, som i det samhälle den tillkommit i. Analysen visar att männen karaktäriseras på ett stereotypiskt vis, där deras handlingar lägger grund för maktpositionerna, medan kvinnorna på motsvarande stereotypa sätt karakteriseras som maktlösa utifrån kropp, utseende och underordning. Detta framställs på ett explicit och ibland övertydligt sätt. Mer implicit framställs etniciteters och klasstillhörighetens betydelse för de manliga karaktärernas inbördes maktpositioner medan kvinnliga karaktärer är objektifierade och underordnade i Vindens namn.

Le but de cette thèse est de mieux contraindre les caractéristiques de Draco, notamment son halo de matière noire. J'ai utilisé plusieurs types d'observations : photométriques et spectroscopiques. Les différents relevés photométriques, obtenus avec les télescopes Isaac Newton Telescope et Canada-France-Hawaii Telescope, m'ont donné des renseignements sur la morphologie de Draco, avec notamment la construction de son profil de brillance de surface. J'ai aussi utilisé ces données pour rechercher directement des effets de marée dans son halo. Comme mes images sont plus profondes en magnitudes que celles des études précédentes, j'ai pu étudier la présence de surdensités dans la partie externe de son halo, notamment le long de son demi-grand axe. Le résultat a montré un halo lisse pour Draco. J'ai aussi pu mettre une contrainte sur la forme du coeur de Draco grâce à des images du centre de la galaxie obtenues par le Hubble Space Telescope. Il s'avère que le profil de brillance de Draco est plat en son centre. Les données spectroscopiques m'ont permis de mesurer la vitesse radiale de la galaxie naine ainsi que sa dispersion de vitesse et confirment les mesures précédentes. J'ai aussi pu tracer le profil de dispersion de vitesse en fonction de la distance. Il a montré que Draco possède un profil plat dans sa partie centrale. Tous ces résultats nous renseignent sur les caractéristiques du halo de matière noire. L'absence d'effets de marée dans le halo de cette galaxie naine confirme bien qu'il est massif. La partie centrale du profil de lumière et de la dispersion de vitesse de Draco apportent de fortes contraintes sur sa forme. Ces résultats sont en faveur d'un halo de matière noire avec un coeur plat. Ceci est en contradiction avec les simulations cosmologiques qui prédisent des halos piqués en leur centre. Ce type de contraintes peut donc servir à améliorer les simulations numériques, mais aussi notre compréhension de la formation des galaxiesThe aim of this thesis is to constrain the properties of Draco, especially its dark matter halo. I used different types of observations : photometric and spectroscopic. The photometric surveys, observed with the Isaac Newton Telescope and the Canadian-France-Hawaii Telescope, is used to determine the morphology of Draco, and in particular with the surface brightness profile. I also use these datasets to directly search for some tidal effects in its halo. As my observations are deeper in magnitude than those of the previous studies, I can study the presence of overdensities in the external parts of its halo, particularly along the major axis. The main result is that Draco has a smooth halo. I can also constrain the shape of the core of Draco with some observations at the center of this galaxy, observed with the Hubble Space Telescope. The surface brightness profile of Draco is flat in its central part. With the spectroscopic dataset, I can measure the radial velocity of this dwarf galaxy, but also its velocity dispersion. I find results that are similar to the prvious studies. I also construct the evolution of the velocity dispersion with distance. It shows a flat profile in the center of Draco. All these results give us some insights on the properties of the dark matter halo around Draco. The absence of tidal streams in the halo of this dwarf galaxy confirms that it is massive. The central part of the light profile and the profile of the velocity dispersion give some strong constraints on its shape. These results are in favor of a dark matter halo with a flat core. This is in contradiction with the cosmological simulations which predict halos with steep cores. These contraints can be used to improve the numerical simulations, but also our understanding on the formation of the galaxies

Full textAbstract:
The essay, based on interviews with eight people, deals with name changes from a foreign-sounding name to Swedish-sounding name. The aim is to investigate the reasons behind the name change and whether experiences of ethnic discrimination were among these reasons. Furthermore, I explore the consequences of the name change, and whether the name change was an effective strategy to avoid ethnic discrimination. The study employs qualitative method; I carry out eight interviews with four women and four men, and analyze the empirical material by means of post-colonial theory in which categorizing, otherness and passing are significant terms. The results show that the name change takes place primarily to reduce a sense of otherness, and the discursively locked positions a foreign-sounding name creates. The name change helps the individual to avoid being questioned as much as before, making the individual more likely to pass. The name change facilitates social interaction with others and leads to a greater sense of inclusion, creating more favorable conditions of work and career development. The subject can thus pass from a position of stranger to a more familiar or ambiguous body.

Retaining structures with nails have been used in recent decades to contain excavation works in several Brazilian cities, including Goiânia. The nails are made of steel bars inserted in inclined or horizontal drilling, with small diameter and involved in cement grout, to ensure the stability of vertical excavations by frictional forces developed in the contact between the soil and nail. Therefore, it is important to understand this friction to design retaining structures. There are lots of calculation methods proposed by many authors to design nails and verify the stability of these structures. The main objective of this work was to review some calculation methods, conduct pullout tests in the field and laboratory tests with samples taken in situ, to evaluate calculation methodologies or parameters that best apply to the soil studied in Goiânia. Among several proposals to estimate the media shear stress in the soil-nail interface (qs) based on SPT, that showed better results in this paper are those from graph lower limit proposed by Ortigão e Palmeira (1997), Springer (2006) and a proposal based on Décourt & Quaresma (1978) to calculate pile lateral friction, using the proper parameter b. Other propositions based on soil type and parameters of the soil that showed good fits were Wong (1995) and Juran et al. (1990). The relation between qs and the shear stress of soil (ts) resulted values between 0,55 and 0,85. Displacement readings were performed during loading and unloading phase, was observed that for small loads, plastic deformations occured in the nail, so is recommended in cases of nail’s numerical analyzes adopt elastic-plastic models. Predictions of nail's elastic deformation, based on piles theory showed good results, however significant plastic deformation occured in nails. The results of shear tests were compared with the pullout tests, indicating that the reduction factor of laboratory results is necessary.
Estruturas de contenção com utilização de grampos têm sido cada vez mais empregadas nas últimas décadas com intuito de conter grandes escavações em diversas cidades brasileiras, incluindo Goiânia. Os grampos consistem em barras de aço introduzidas em perfurações inclinadas ou horizontais de pequeno diâmetro e posterior injeção de calda de cimento, de forma a garantir a estabilidade de escavações verticais pelas forças de atrito desenvolvidas no contato solo-grampo. Sendo assim, é fundamental o conhecimento deste atrito para o dimensionamento destas contenções. Existem vários métodos de cálculo propostos por diversos autores para o dimensionamento de grampos e verificação da estabilidade dessas estruturas. O objetivo principal deste trabalho foi o de revisar alguns desses métodos de cálculo, realizar ensaios de arrancamento em campo e também ensaios em laboratório com amostras retiradas de uma obra com múltiplos subsolos, para avaliar as metodologias de cálculo ou parâmetros que melhor se aplicam aos solos estudados da cidade de Goiânia. Dentre as diversas proposições para estimativa da tensão cisalhante média no contato sologrampo (qs) aquelas baseadas em ensaio SPT que obtiveram melhores resultados neste trabalho foram o limite inferior do gráfico proposto por Ortigão e Palmeira (1997), Springer (2006) e uma proposição baseada no Método Décourt e Quaresma (1978) para atrito lateral em estacas, com o ajuste adequado do parâmetro b. Outras proposições baseadas no tipo e parâmetros do solo que apresentaram bons ajustes foram Wong (1995) e Juran et al. (1990). Foram feitas comparações entre qs e a tensão cisalhante do solo (ts) encontrando para esta razão valores entre 0,55 e 0,85. Como foram realizadas leituras de deslocamentos tanto na fase de carregamento quanto na fase de descarregamento, notou-se que para pequenas aplicações de carga já acontecem deformações plásticas no grampo sendo recomendado nos casos de análises numéricas em grampos a adoção de modelos elasto-plásticos. As previsões de deformações elásticas dos grampos, baseadas em teorias de estacas apresentou uma boa aproximação dos ensaios, que entretanto apresentaram relevante deformação plástica nos ensaios realizados. Os resultados de ensaios de cisalhamento em amostras indeformadas dos solos foram comparados com os ensaios de arrancamento, indicando que o fator de redução dos resultados de laboratório é necessário.
