Magnetiskresonanstomografi, MRI, är en användbar teknik inom flera områden, i denna uppsats ligger fokus på användning inom medicin. Fysiken som ligger bakom MRI presenteras, som t ex uppdelning av energinivåer och kärnmagnetiskresonans. Uppbyggnad och tekniken som ligger bakom MRI har även studeras. Sedan har det gjorts jämförelse mellan MRI, röntgen och datortomografi. Utöver litteraturstudierna har simulering gjorts. I denna del har en modell för hjärnan byggts i programmet Comsol Multiphysics.

The Sand Catcher                                                       The thesis project The Sand Catcher investigates the encounter between permanent structures and an ever-changing landscape. The migrating sand dune Råbjerg Mile in northern Denmark is 40 meters high and moves more than 15 meters every year. By introducing a solid structure on the site, the fast movement of the sand dune is emphasised and thereby our view of time and space.Through intuitively building models with varied openings and densities I investigated how architectural elements react with sand. From these experiments a series of spatial features and effects were found, generated from the meeting with the sand.The Sand Catcher is a solid and permanent structure. The sand is the liquid element that generates new spaces, circulations and experiences.

Often, the green is handled as an opposite to the built, but if it could be seen as a part of the built and the society, the planning will be easier to handle. The thesis work wants to create a method that treats villages in an analytic way in a context; with green, blur, grey and all the other colors that together are the completeness.This master's thesis is made to be used as foundation in detail plannng in the municipality of Örkelljunga. Target audience is on one hand those who work with planning and green matters in Örkelljunga municipality, but also other planners who work with landscape.Literature in the field of green city planning has been studied and 30 methods for analysis have been valued. The method for analysis that has been used in this work is a merging of ten different methods and has included literature studies, sketches, interviews and work on spot. The ten methods are consciously chosen to together make one comprehensive and true image of the village, as far as it is possible.

This study illuminates one part of the mathematic teaching in school, which is mathematical problem solving in groups. It examines teacher?s and student?s ideas about what conditions it takes to be able to learn in groups. Further on, it studies the importance of group structure when it comes to working with mathematical problem solving in groups from a process focused and/or a product focused learning. Through observations of student groups and interviews with the students and the mathematic teachers, the material has been compiled and analysed under three different headings: conditions for learning in a mathematical problem solving situation, importance of group structure in a mathematical problem solving situation and process versus product.

ABSTRACTThis thesis focuses on the OPEC oil crisis of 1973 and its impact on the Scandinavian countries of Sweden and Denmark. Starting from Walter Carlsnaes theory of energy vulnerability, the concepts of vulnerability and national security are tested on the selected cases and an array of policy alternatives are assessed. Posited available options like oil stockpiling, conservation, renewable energy and international coordination are evaluated as means for ameliorating the vulnerability of the nations. The theory chosen is further expounded with a consensus element to reinforce its explanatory power. The thesis utilizes a wide range of material from parliamentary records to daily newspapers in an attempt to shed some light on the interplay between economics and politics.Sweden and Denmark evince diverging developments despite their common starting point with exceptionally high oil dependencies and can be located on different ends of the energy policy gamut.

BakgrundAntalet svenskar som sparar i aktier har på 20 år mer än fördubblats. Värderingsmetoderna har genom tiderna förändrats. Kassaflödesvärdering dominerar för tillfället tillvägagångssätten att värdera företag/aktier. Det debatteras huruvida kassaflödesvärdering är en pålitlig metod eller ej. Det finns flera kassaflödesmodeller att välja bland.

Background for the research problems: Small companies are very important for the economic stability and development, something which the economic crises in recent years have underlined. Therefore it?s important to minimize administrative costs for smaller companies and also in other ways facilitate their further development. For these reasons accounting has been simplified and auditing abolished for smaller companies in many countries. In Sweden auditing for small companies was abolished nearly three years ago.

The purpose of this study was to analyze the level of the uniform way of interpretation from the Swedish asylum officers at the Swedish Migration Board, of asylum investigations for asylum seekers who claim sexual orientation as reason of refuge. The interviews with the officers were analyzed in relation to the policy document with investigation- guidelines and methodology.The results of the study showed that there was a uniform way to conduct asylum investigations and interpret the policy document, this despite that the document was found to be ambiguous in certain aspects. The uniform interpretation of the asylum officers was explained by the knowledge and understanding that exists within institutional organizations. This because the asylum officers at the Swedish Migration Board might have similar experience, knowledge and also the demands related to asylum investigations.The uniform interpretation demonstrated a strong similar common understanding of investigative work within the agency. This suggests a certainty that the investigations are carried out in a similar way regardless of which asylum officer within the institution conducting the investigation which indicates a well-functioning ?rule of law? for the asylum seekers. .

The purpose of this thesis is to create a deeper and also a better understanding about how each of the professional secrecy and obligation to report are perceived from auditors and further investigate how the potential conflicts based on independence and ?can be suspect? are handled by the auditors. The purpose has been achieved through interviews with four different accounting firms.The interviews were conducted with Grant Thornton, BDO Mälardalen AB, PwC and KPMG to answer the research questions. Subsequently, a hermeneutic approach was used to since the interpretation of the interviews was considered as important to obtain knowledge of the respondent?s perception about the topic.

The proportion of women entrepreneurs in Sweden is, as in many countries, smaller than the proportion of men entrepreneurs. Sweden has therefore created political measures with the ambition to increase women entrepreneurship. However, knowledge about the determinants of women entrepreneurship is needed in order to enable the promotion of it and, at the same time one can question the treatment of women entrepreneurs as a homogenous group. The purpose of this thesis is to investigate the determinants of women entrepreneurship and whether these determinants fluctuate regionally. If this proves to be the case, a more spatial/individual approach should be used, when creating measures to promote entrepreneurship.

The study examines conceptions of identity among girls with foreign background. The aim was to study how identity is understood by the girls based on ethnicity, images of the origin, the value of gender and the meaning of the family. The theoretical approach was post-colonial theory based on Stuart Hall in combination with gender theory by Yvonne Hirdman. The study was conducted using qualitative individual interviews of open character with six girls. They were aged 17-18 years old and were born in Sweden or had lived here since the age of six.

The aim of this master thesis is to investigate how parents? in multilingual families perceive language learning and reading for young children, and how their practice of this can be understood in relation to their language situation and cultural background.This study focuses on the interaction between parents? and young children in the light of the literacy practice. Important concepts such as early childhood literacy and family literacy have been used to study language, culture and literacy practice as phenomena that interact. The theoretical framework is a sociocultural perspective. Through qualitative interviews with seven parents?, it was found that multilingual families have a strong ambition for their children to learn all the languages spoken in the family.

Background: Each year approximately 30 000 people suffer from stroke in Sweden, often with substantial mental and physical consequences. Those who suffered from stroke handled the situation by mourning what they had lost and by accepting their changed body and life situation. For those who provide care for people who has suffered a stroke help and support was required. The caring science perspective was based upon caring and suffering. Aim: The purpose of this study was to describe family caregivers? experiences of caring for persons who had suffered a stroke.
