Utvärdering av dimensionell stabilitet i PWR-patroner i Ringhals
Dimensional stability is an important aspect of fuel mechanical design and licensing of new fuel designs for nuclear power plants. Dimensional changes within the reactor can affect the safety margins against overheating of the cladding and the pellets, therefore it is crucial that the dimensional changes are kept to a minimum.The profits per produced kiloWatt hour continue to decrease for the Swedish nuclear power plants. Some reactors are even operated with a calculated loss. To reduce fuel costs and thereby improve the profit some reactors are operated with higher uranium enrichment, so that the assemblies can reach a higher average burnup. This increases the neutron fluence to the pellets, cladding an spacers.
Konstituerade kön i mytologisk allegori : En diskursiv läsning av Olof Rudbecks Atlantica
The intention of this essay is to inquire into the (re-)constitution of gendered/sexed identities in a gothicistic discourse. The used material is the work Atlantica, chapter 5, vol. 2, written by the Swedish historian/Medical professor Olof Rudbeck. I have chosen this chapter for its description of mythological characters relationship with the earth, the sun and the moon. A description based on a concept of strength and reproduction as gendered characteristics.
Territoriell stigmatisering. En litteraturbaserad studie om möjligheten att använda begreppet ?territoriell stigmatisering? i förklaringsmodeller bakom ojämlikhet i hälsa.
Introduction: Public health is based on the determinants of health. They mutually influence each other. Structural factors and life conditions contribute to health inequality both within and between countries. Health inequality can be seen between different social groups, which can be the cause of differences in living conditions, health behavior and disease vulnerability. One of the consequences of this is segregation which means that certain groups live apart, where this distribution can be connected to economic resources and/or ethnicity.
Kvinnoföreningar - rörelser för kulturöverskridande möten och social inkludering
This is an interview based qualitative case study on two Women's Migrant Associations in Malmoe, which I interpret as being part of a women's movement, with characteristics of a new social movement. The aim of this study is to get a deeper understanding on how the collective identity is being constructed, in this women's movement where the membership is not based on an exclusive ethnic identity.I make a two dimensional analysis that departs from a social constructivist underpinning, including the theories Transversial Politics, Postcolonial feminism and New Social Movement Theory.First I analyze the construction of collective identity from the external social and cultural context, and get confirmed that the collective identity of the movement is based on a common experience of social exclusion and a plurality of actions that aims to fight the structural injustices based on gender and ethnic discrimination. Secondly I analyze how the collective identity is being constructed and maintained from the interactions between the members of the movement, from an understanding of Transversial Politics. My findings show that the members of the movement interact in a participatory democratic way which generally corresponds to Transversial Politics. According to Transversial Politics this can lead to a construction of an empowered inclusive collective identity for the members and as my empirical study confirms it also means possibilities for deconstruction of boundaries between social groups..
Den kommunala folkhälsosamordnaren söker sin arbetsroll
Coordinator of public health has recently become a new profession in the field of Health Promotion. During the last few years the pedagogic perspective has been increasingly important for the coordinators as a way of adapting their work methods to the circumstances. The conditions for coordinators of public health differ between municipalities and thus their tasks and responsibilities may vary with the local structure. According to the literature there are several ways to conduct Health Promotion and it is in the hands of the coordinator to adjust the methods to fit local conditions. The purpose of the study was to examine what influences the coordinators of public health and how that affects their work methods.
Evaluation of Capital Structure Arbitrage in the Equity-Credit Markets
Purpose: The purpose of this thesis is to test for the existence of Capital Structure Arbitrage oppertunities in the equity-credit markets. Methodology: The mispricing of Credit Default Swap contracts are calculated and used as input in an Equity-Credit market trading strategy. The returns are then evaluated with a modified Value-at-Risk simulation. Theoretical perspectives: A Merton-based structural model, CreditGrades, is used for credit pricing and a mispricing-convergence trading-strategy between the credit and equity markets is implemented. Empirical foundation: Daily quotes for the Credit Default Swap spread of 37 European firms were collected for a period of two years, as well as equity-prices for the same period and the previous two years, used for model calibration.
Vad innebär barnfattigdom i en välfärdsstat som Sverige? : En jämförande studie om hur begreppet barnfattigdom har förändrats över tid i den offentliga debatten
The purpose of this essay was to study some selected magazine articles by examining how the concept of child poverty is produced in the public debate, and to see if the definition of the term has changed over time. The theoretical approach on which this study is based has been used as a tool to provide better understanding on the subject. Furthermore, theories of consumer society, the "collateral damage" and the theory of welfare regimes have been used. In the previous research presented in the paper focuses on linking children and families living in precarious economic conditions, consumer standards and welfare systems that characterize society.This study has a qualitative approach as it attempts to capture and increase understanding of how the concept of child poverty can be understood from a Swedish context. The study is based on newspaper articles that are studied using a structural text analysis.
System, stabilitet och makt - informationsdiskursen i Organizing Knowledge
TitleSystems, Stability and Power. The Discourse of Information in Organizing Knowledge.AbstractThe aim of this Master's thesis is to inquire into the consequences of an unequal distribution of power between information discourses in the field of knowledge organisation. A deconstruction of Jennifer Rowley's and John Farrows introductory textbook Organizing Knowledge from 2000 is related to the major discourses of information in LIS. Questions posed in this study are: What meaning is ascribed to information in the material studied? Which information discourses are given a dominant position? Which are excluded? and: How does this affect the construction of the library and information science student's identity, in relation to practices of knowledge organisation? The theoretical framework is provided by Ernesto Laclau's and Chantal Mouffe's theory of discourse and combined with techniques for text analysis originating from the work of Norman Fairclough.The analysis reveals a strong domination of a cognitive discourse of information that underlines the importance of information systems for the organisation of knowledge.
Bålstabiliserande träning vid ländryggssmärta : En experimentell single-subject design studie
Bakgrund: Ospecifik ländryggssmärta är en av de vanligaste orsakerna till att man söker hjälp inom primärvården. För långvarig, ospecifik ländryggssmärta är träning ett förstahandsval och fokus har under det senaste årtiondet legat på bålstabiliserande träning. Psykosociala faktorer som self-efficacy och rörelserädsla kan vara viktiga att beakta vid behandlingen då de spelar en roll i hur ländryggssmärtan utvecklas. Syfte: Att undersöka hur skattad smärta, self-efficacy och rörelserädsla samt funktionsnivå förändrades hos enskilda patienter med långvarig, ospecifik ländryggssmärta under och efter en intervention i grupp med bålstabiliserande träning. Metod: Designen var en A-B-A single-subject design (SSED).

This report describes how the system may be exposed to oscillations and how this can lead to resonance. Resonance is a phenomenon that occurs when a system is affected by external periodic oscillations with frequencies close to the system's natural frequencies. Structures subjected to resonance can risk great damage and destruction, why resonance is something that is important to take into account when designing structures. Alternative ways to counteract resonance is to supply damping in the system. Damping means that the resonance decreases instead of letting the amplitude increase.The report discusses some examples on constructions that have experienced the effect of resonance.
Hur sprider vi kunskap? : En kvalitativ studie om Räddningstjänstens kunskapsöverföring
Syftet med denna studie är att undersöka hur Räddningstjänsten sprider kunskap som erhållits från erfarenheter och övning, samt vilka strukturella faktorer som påverkar denna spridning. Med strukturella faktorer avses exempelvis hierarkier, avdelningsgränser, strategier för kunskapsöverföring och belöningssystem. Studiens empiri har samlats in genom semi-strukturerade intervjuer och är således en kvalitativ studie. Urvalet består av sju medarbetare på olika befattningar som bedömts som nyckelpositioner för kunskapsspridning. Studien utgår ifrån olika Knowledge management-strategier och Communities of practice för att förklara skapande och spridning av organisatorisk kunskap. Resultatet påvisar att det finns olika spridningsmetoder för kunskap som består av ett avvikelsesystem, insatsrapporteringssystem samt Communities of practice inom arbetslagen.
Elektromagnetisk och mekanisk design av en 20MW turbogenerator
At the Division of Electricity at UppsalaUniversitythere are ongoing researches, including a research concerning turbo generators.Turbo generators produce a large share of electricity in the world; however they are costly mainly due to the fact that the cooling and ventilation that are needed to eliminate the excess heat from the generators are expensive. Turbo generators work with high efficiency and in this project, the main task is to simulate a generator while taking into account that the generator must be designed against self-oscillation, centrifugal force, exhaustion and heat. The turbo generator must be simulated without being too expensive and complicated.In this project, the dimensions of the turbo generator depend on the efficiency of it, and where the losses are in the generator. Furthermore, the optimum values need to be chosen with the help of the ACE simulation program. The report begins with an introduction describing the project followed by a task description that is dealing with the project.
Bibliotekets roll i integrationspolitiken ett postkolonialt perspektiv
Sweden of today is a so-called multicultural society. In this thesis we wanted to examine how mono, multi- and intercultural issues are expressed in culture-political documents. We also wanted to know how librarians for whom these documents are supposed to be guidelines expressed themselves in these matters. Monoculturalism can be described as a static perspective laid upon culture which emphasises cultural purity. A multicultural society describes a society were the nation consists of many different cultures alongside each other, without a genuinely common core.
