This thesis work is the last part of the Master of Science education inmechanical engineering at KTH, Stockholm.The aim of this project was the development of a Multi-zone modelfor NOxformation in Diesel engines. Because of the stringent emissionlegislations, great effort is made to decrease the fuel consumption and theharmful emissions of internal combustion engines. Computer simulationsplay a decisive role in this context because they substitute the expensiveand time-consuming laboratory tests.The model is based on a multi-zone approach and uses the wellknownExtended Zeldovich Mechanism which gives a relation to calculatethe NO formation rate using the concentration of different gas speciesinvolved in the process.All the most important phenomena involved in the Diesel combustionhave been modelled. A special attention is then paid to the equilibriumconcentration calculation; this is a significant part of the model whichstrongly influences the following steps.A Simulink model has also been developed. This second version isbased on the previous model and it is made especially to allow theconnection with other external softwares, GT-power in this case.

Varje år befinner sig cirka 95 000 barn på sjukhus i Sverige. För att kunna möta dessa barn på en adekvat nivå samt att kunna vara korrekt i sin profession krävs det att sjuksköterskor besitter stor kunskap och respekt inom sitt område. Barn kan uppleva att de har en minskad kontroll över sin verklighet när de har blivit sjuka och hamnar i en ny miljö. Avsaknaden av kontroll och osäkerhet kan leda till ovisshet samt oförutsägbarhet. Osäkerheten bidrar till en känsla av att mista greppet om situationen barnen befinner sig i.

In recent years, global organizations safeguarding financial stability has started to track commercial property markets. One of the reasons for this refers to the fact that commercial property constitutes a large share of bank lending. Simultaneously, bank exposures to commercial property are extensive and risky since collateral values are strongly correlated to borrowers cash flows. Since banks are viewed to play a key role for financial stability, studying the relationship is well motivated. To better understand how commercial property markets interact with financial stability, this paper develops an econometric model for studying the commercial rental market.

The deregulation during the last decade within the airline businesses have called upon a more fierce competition among airlines. This fact forces airlines to continuously focus on service development in order to offer attractive solutions to satisfy customers changing needs and stay competitive. This paper focuses on service development at Scandinavian Airlines. The aim of this case study is to examine the sources of information used in service development and new service development at Scandinavian Airlines. Further the aim is to examine whether information derived from customers can be shown to play a more important role in either service development or new service development.

The aim of this Master?s thesis is to examine how the introducing of municipal library plans has influenced some compulsory schools in Malmö. I wanted to know if the library plan is a possible way to improve the quality of the school library. Through qualitative interviews with four school librarians and four headmasters, I investigate their knowledge of the library plan and their opinion of the possibilities to realize the directions of the plan. The theoretical framework is based on a model of organizational culture by Bakka, Fivelsdal and Lindkvist.

The world is in a stage of climate crisis where the average temperature is rising, with consequences such as, melting ice sheets, increasing sea levels, and floods. The climate panel of the UN, IPCC, has stated that this is a reaction of anthropogenic emissions of greenhouse gases. The most important gas is carbon dioxide, which contributes with 80 per cent to the on going climate crisis.The increasing emissions of carbon dioxide are connected to human consumption patterns. This puts pressure on the earth, as humans demand more and more resources. Today the earth needs one and a half year to regenerate the resources humans? demand of it, by the year 2030 we will need two planets in order to cope with this increasing demand of resources.At a global level it is established that richer countries have a stronger consumption pattern than poorer, and thus generate higher levels of carbon dioxide emissions.

The purpose of this essay is to examine how the supernatural and the occult are portrayed inpopular culture. To be able to do this, I have chosen to perform a discourse analysis of the twofirst novels in the L. J Smith series The Vampire Diaries. The novels are called TheAwakening and The Struggle.I apply the following questions in my analysis to narrow down the perspective further.?In what situations are supernatural used in the books and what part does it play??How does the supernatural affect the main characters and how is this portrayed in the novel??How is the supernatural portrayed depending on the gender of the character?I will focus mostly on the vampires since they generally are the ones who introduce thesupernatural elements into the story.I am applying gender theory in my discourse analyses of the novels, to hopefully be able togive a wider picture of the supernatural in relation to gender in the novels.I begin with analyzing the main discourses in the story, revolving around the supernatural.Secondly I analyze what impact the supernatural has on the main character.

The subject of this paper is the mediation of norms about sexuality, from personnel working at the Swedish ?ungdomsmottagning? (youth centre for service and counselling about sexual health), to the visiting teenagers. The purpose of the empirical study is to investigate how the staff understands the part of their work that implies giving advice about sexuality; how they work, which norms they have about youth sexuality and how they see their roll as advisers. To answer these questions, I have interviewed six staff members working at different youth centres. Three of them work as social counsellors and three as midwifes.The main area of work at the centre consists of individual appointments, but another important task is meeting with school classes visiting for purposes of study.

The purpose of this essay has been to describe and compare the personal qualities that the Swedish newspaper Dagens Nyheter (DN) tried to associate Barack Obama and John McCain with during the American presidential election campaign 2008. The main question to be answered is: What social and physical characters as well as what personal experiences, interest and resources did DN tried to emphasize regarding John McCain and Barack Obama during the American presidential election campaign 2008. The theoretical starting-point has been John B Thompson?s theory of the mediated publicity and John Corner´s theory of political persona and spheres of action. Various DN news texts, in all 38 articles, have been examined by content analysis from 25th of august to the 4th of November.

This report describes a study of how educationalists, from one preschool group, approach to and respond to children ?s creative activity in preschool. To answer the survey ?s purpose I used four research questions, which is the following:-What function do the educationalists give the creative activity in the working?-How do they see the importance of thecreative activity for thechild and its development?-How doeducationalists considerthat theyrespond to the child's creative activity?-Is thereany norms surrounding creative activity in preschool?The theoretical base of the study is rooted in the sociocultural perspective, where creative activity and visual arts can be seen as mediating cultural tools. The method is a qualitative interview of five preschooleducationalists.

AbstractPolitical Science, level III thesisSpring semester 2010Author: Emelie AlfredssonSupervisor: Tomas Mitander"A Changed Leadership? - A study of the EU leadership from a institutional standpoint, related to multilateral environmental negotiations"The EU has for a relatively long time considered itself a leader in the environmental policy area as a whole as well as in multilateral environmental negotiations. This study attempts to classify and identify the European leadership with the purpose of relating it to the institutional framework of the Union. The treaties of the European Union decide its ability to act and its institutions the right to engage in different policy areas, the environmental area being the focus of this study. With the recent ratification of the Lisbon treaty this study aims to make out if the type of leadership the Union showed during the Kyoto negotiations has changed with the new treaty, into a new type during the COP-15 meeting in Copenhagen.

Abstract Back ground: Home based care is a meaningful activity giving patients and their families a chance to live their lives as close to normal as possible. Advanced palliative care is today provided at home, although geography does play a role in shaping that care. A rural setting can mean that conditions for such care differ from those in urban areas.Purpose: To describe the experiences of district nurses in palliative home care settings in a rural community.Method: Semi structured interviews with seven district nurses. The interviews were recorded digitally and transcribed in a precise fashion. A method of qualitative analysis of the contents, inspired by Burnard, was used to analyze the material.Results: Palliative care places high demands on the competency and experience of district nurses.

The aim of this Master?s Thesis is to study readers and authors of Harry Potter fan fiction, in order to answer the question of why they read and write fan fiction about Harry Potter, and which factors determine what kind of fan fiction stories they read. The empirical material consists of three qualitative interviews with fan fiction readers and authors, and a textual analysis of four internet forums for discussions about Harry Potter and fan fiction. The theoretical background is based on reception theory and reader-response criticism. The results show, that commitment to, and interest in, the source material is an important reason as to why the participants of the study read and write Harry Potter fan fiction.

The aim of this study is to identify the dominating discourse in Swedish newspapers concerning perpetrators who committed sexual offence against children. The study is based on the idea that the media representation play a significant role to the public opinion and awareness of the perpetrators. The study is based upon a selection of 103 articles published between January 2003 and November 2013, taken from four of the biggest daily newspapers in Sweden; Aftonbladet, Dagens Nyheter, Expressen and Svenska Dagbladet. The methodological and theoretical approach in the study has been the one of discourse analysis through which one dominating discourse along with two subsidiary discourses could be identified. The discourse considered to be dominating is the one who presents the perpetrators through the discrepancy between the actions committed and the description of the perpetrator.
