    Charging effects in niobium nanostructures

    Full text link
    Three types of metallic nanostructures comprising niobium were investigated experimentally; in all three types, electric transport at very low temperatures was governed by Coulomb blockade effects. 1. Thin film strips of niobium could be tuned into resistor strips by an electrochemical anodisation process, using microfabricated masks and in situ resistance monitoring. These resistors showed a transition from superconducting to insulating behaviour with increasing sheet resistance, occurring at a value approximately equal to the quantum resistance for Cooper pairs, h/(4e^2). 2. Combining the anodisation technique with lateral size minimisation by shadow evaporation, devices in a single electron transistor-like configuration with two weak links and a small island between these were made. Direct evidence for the Coulomb blockade in the anodisation thinned niobium films was found when the transport characteristics could be modulated periodically by sweeping the voltage applied to a gate electrode placed on top of the structure. 3. Conventional single electron transistors with Al base electrodes, AlO_x barriers formed in situ by oxidation, and Nb top electrodes were made by angular evaporation. The output current noise of such a transistor was measured as a function of bias voltage, gate voltage, and temperature. The low frequency noise was found to be dominated by charge input noise. The dependence of the noise on the bias voltage is consistent with self-heating of the transistor activating the noise sources.Comment: PhD thesis, 177 pages, 42 figures (images downsampled

    Adaption of Girlhood : Norm-Confirming and Norm-Breaking in Girls’ Books Translated from English to Swedish and Finnish between 1945–1965

    This interdisciplinary thesis is the first more comprehensive study of girls’ book translations in Sweden and Finland. The study examines adaptation of the image of girlhood in girls’ books translated from English to Swedish and Finnish between 1945–1965. Girls’ literature and girls’ books are children’s literary genres about girlhood, about girls’ lives and what it means to be a girl in a certain historical context. Girlhood is depicted in relation to norms for how girls are expected to behave, which means that the girl protagonists often both confirm norms by adapting to the expectations of society and rebelliously challenge these norms. Translations of girls’ books are influenced by norms of girlhood, narrative norms, and translations norms. These result in adaptation, a translations practice where translations are adapted to the norms of the target context (the target culture and the publisher) and to the target audience, in this case young girls. The frame of reference is the polysystem theory, according to which all genres and literary works belong to the literary polysystem, a network of partly overlapping systems in which tensions arise between the center with higher prestige and the periphery with lower prestige. The objective of this study has been to analyze how the peripheral position of girls’ literature within the general literary polysystem and the internal relations between the center (Bildungsromane with higher status) and the periphery (series books with lower status) within the girls’ literary polysystem influences the amount and type of adaptation in girls’ books. The ways in which this peripheral position impacts the image of girlhood in the books is also examined. A further aim has been to analyze whether the Finnish girls’ book system has been influenced by the Swedish system due to Finland’s peripheral position in the Nordic translation system. The qualitative material consists of three Bildungsromane by L. M. Montgomery, Jean Webster, and Laura Ingalls Wilder, and three series books by Helen D. Boylston, Carolyn Keene (a pseudonym), and Helen Wells, as well as their Swedish and Finnish translations. These books represent the series that, according to my initial quantitative survey, were the most prominent among the girls’ books published in both Swedish and Finnish in 1945–1965 (52 books). To contextualize the material, a paratextual analysis of publisher correspondence and the covers and cover texts of the translations has been conducted. The analysis shows that the Nordic countries were a uniform system with Sweden and Norway at its center, as books and series came to Finland via these countries, and Swedish and Norwegian translations were used as source texts for three of the Finnish translations in my study. This interdisciplinary study has three methodological starting points for the analysis of the effects of adaptation on the image of girlhood. The primary descriptive translation studies method consists of a comparative and categorizing adaptation analysis, my linguistic method involves an analysis of semantic-pragmatic features and pragmatic language functions, and my literature studies method is a narrative analysis of character indictors in relation to gender stereotype schemata for masculine and feminine narration, which represent norm-confirming and norm-breaking narration. The results demonstrate that both target-oriented abridged translations and source-oriented faithful translations appear in both the Bildungsromane and series book material. Thus, the amount of adaptation does not correlate with the polysystemic position of the translation. This indicates that the polysystem hypothesis that translations with a peripheral status are likely to be target-oriented is not supported within the girls’ book genre. Instead, adaptation occurs according to commercial, didactic, and pedagogical norms regardless of the polysytemic position. In the adapted translations, the image of girlhood is influenced by downplaying of character traits associated with norm-breaking girlhood, and by an increase of plot-oriented narration, which is the norm within children’s literature.Denna avhandling Ă€r den första mer omfattande undersökningen av flickboksöversĂ€ttningar i Sverige och Finland. Flicklitteraturen och flickboken Ă€r en barnlitterĂ€r genre som handlar om och förhĂ„ller sig till att vara flicka, att göra flickskap i en viss tid och pĂ„ en viss plats. Flickskap Ă€r bĂ„de anpassning till och uppror mot samhĂ€llets normer eller förvĂ€ntningar. DĂ€rför uttrycker gestaltningen av flickskap ofta bĂ„de normbekrĂ€ftande och normbrytande. ÖversĂ€ttningar av flickböcker pĂ„verkas av normer för flickskap, normer för berĂ€ttande och översĂ€ttningsnormer. Dessa leder till adaption, som innebĂ€r att översĂ€ttningar anpassas till mĂ„lkulturens och det utgivande förlagets normer och översĂ€ttningens mĂ„lgrupp, som bestĂ„r av unga flickor. Adapterades eller anpassades gestaltningen av flickskap nĂ€r flickböcker översattes frĂ„n engelska till svenska och finska under perioden 1945–1965 och i sĂ„ fall hur? Var översĂ€ttningarna kĂ€lltrogna eller mĂ„lanpassade? FramhĂ€vdes normbekrĂ€ftande eller normbrytande drag? Var praktikerna enhetliga i Sverige och Finland? Denna tvĂ€rvetenskapliga studie söker svar pĂ„ dessa frĂ„gor genom en kombination av översĂ€ttningsvetenskapens, litteraturvetenskapens, sprĂ„kvetenskapens och arkivforskningens metoder. Studiens material bestĂ„r av tre bildningsromaner av L.M. Montgomery, Jean Webster och Laura Ingalls Wilder med högre status och tre lĂ„ngserieböcker av Helen D. Boylston, pseudonymen Carolyn Keene och Helen Wells med lĂ€gre status samt deras svenska och finska översĂ€ttningar. Dessa böcker representerar de serier som enligt en inledande kvantitativa analys var mest framtrĂ€dande bland de flickböcker som utgavs pĂ„ bĂ„de svenska och finska under perioden 1945–1965 (52 böcker). För att kontextualisera materialet har Ă€ven dels förlagskorrespondens, dels översĂ€ttningarnas omslag och omslagstexter analyserats. Analysen av förlagskorrespondensen och översĂ€ttningarna visar att Norden under perioden utgjorde ett enhetligt fĂ€lt med Sverige och Norge som centrum. Författarskapen kom till Finland via dessa lĂ€nder, och svenska och norska översĂ€ttningar anvĂ€ndes som kĂ€lltexter för tre av de finska översĂ€ttningarna i materialet. Resultaten av analysen av adaptioner i materialet visar att bĂ„de mĂ„lkontextanpassade förkortade översĂ€ttningar och kĂ€lltrogna översĂ€ttningar förekommer i sĂ„vĂ€l bildningsroman- som lĂ„ngseriematerialet. DĂ€rmed stĂ„r mĂ€ngden adaption inte i relation till översĂ€ttningens status. I de anpassade översĂ€ttningarna sker anpassningen enligt kommersiella, didaktiska och pedagogiska översĂ€ttningsnormer oberoende av översĂ€ttningens status. FramstĂ€llningen av flickskap pĂ„verkas dels genom att karaktĂ€rsdrag som förknippas med normbrytande flickskap nedtonas, dels genom att berĂ€ttandet blir mer handlingsorienterat, vilket Ă€r normen inom barnlitteratur.Helsinki: Unigrafia, 202

    The geometry of manifolds with asymptotically flat ends

    This monograph thesis is divided into two chapters. In the first, "A study of ALF structures", we prove that the structure at infinity of a ALF manifold is essentially unique, i.e. any structures associated to a complete non-compact Riemannian manifold that is asymptotic to a circle fibration over an Euclidean base, with fibres of asymptotically constant length, are related by a rigid motion plus low-order terms. The proof is based on showing the existence of harmonic coordinate-like functions. In the second, "A study of fibred boundary metrics", we show the existence of a unique transverse diffeomorphism associated to a fibred boundary metric, i.e. a map that transforms a fibred boundary metric into another with no transverse components. Furthermore, we demonstrate that a diffeomorphism that maps a fixed fibred boundary metric into another can be uniquely decomposed as a composition of an isometry on the boundary and a small diffeomorphism. We present several examples of such transverse diffeomorphisms together with their decompositions. We conclude this second chapter by introducing the notion of linear mass at infinity of a fibred boundary metrics, and give a full classification of the 3-dimensional case associated to asymptotically euclidean fibred boundary metrics. Denna monografiavhandling bestĂ„r av tvĂ„ kapitel. I det första, "A study of ALF structures", visar vi att strukturen vid oĂ€ndligheten för en ALF mĂ„ngfald Ă€r vĂ€sentligen unik, dvs. att strukturer som Ă€r associerade till en fullstĂ€ndig icke-kompakt RiemannmĂ„ngfald som Ă€r asymptotisk mot en cirkelfibrering över en Euklidisk bas, med fibrer av asymptotiskt konstant lĂ€ngd, Ă€r relaterade genom en Euklidisk transformation plus lĂ€gre ordningens termer. Beviset bygger pĂ„ att visa existens av harmoniska koordinatliknande funktioner. I det andra, "A study of fibred boundary metrics", visar vi existensen av en unik transversell diffeomorfi associerad till en randfibrerad metrik, dvs. en avbildning som transformerar randfibrerad metrik till en annan utan transversella komponenter. Vidare, sĂ„ visar vi att en diffeomorfi som avbildar en viss randfibrerad metrik till en annan unikt kan delas upp som en sammansĂ€ttning av en isometri pĂ„ randen och en liten diffeomorfi. Vi ger flera exempel pĂ„ sĂ„dana transversella diffeomorfier tillsammans med deras uppdelningar. Vi avslutar det andra kapitlet med att introducerade begreppet linjĂ€r massa vid oĂ€ndligheten för randfibrerade metriker, och vi ger en full klassifikation av det 3-dimensionella fallet för asymptotiskt Euklidiska randfibrerade metriker. Esta tese estĂĄ dividida em dois capĂ­tulos. No primeiro, "A study of ALF structures", provamos que a estrutura no infinito de uma variedade ALF Ă© essencialmente Ășnica, i.e. quaisquer estruturas associadas a uma variedade de Riemann completa e nĂŁo compacta que seja assimptĂłtica a um fibrado circular com espaço base Euclidiano, com fibras de comprimento assimptoticamente constante, estĂŁo relacionadas por um movimento rĂ­gido seguido de termos de ordem inferior. A demonstração baseia-se em mostrar a existĂȘncia de funçÔes harmĂłnicas com um comportamento semelhante a coordenadas. No segundo, "A study of fibred boundary metrics", provamos a existĂȘncia de um Ășnico difeomorfismo transversal associado a uma mĂ©trica fibrada de fronteira, i.e. um mapa que transforma uma mĂ©trica fibrada de fronteira em outra sem componentes transversais. Por conseguinte, demonstramos que um difeomorfismo que mapeia uma mĂ©trica fibrada de fronteira em outra pode ser decomposto unicamente na composição de uma isometria na fronteira e um pequeno difeomorfismo. De seguida apresentamos diversos exemplos de difeomorfismos transversais em conjunto com as suas decomposiçÔes. ConcluĂ­mos este segundo capĂ­tulo com a introdução do conceito de massa linear no infinito de uma mĂ©trica fibrada de fronteira, e fornecemos uma classificação completa do caso tridimensional associado a mĂ©tricas fibradas de fronteira assimptoticamente euclidianas. QC 2023-08-21</p
