Chemicals are everywhere in todays society, in humans, animals as well as nature, and they are difficult to avoid. The chemical industry is regarded to be the fastest growing industrial sector, accounting for ten percent of the global economy. A large amount of chemicals are used to produce hygiene products and cosmetics, products that in Sweden only are consumed in quantities of 110 tons per day. Researchers find it increasingly difficult to determine which chemicals that are dangerous and which that are safe, and how they might affect us in the long run. Correlations have been found between chemicals, diseases and other health effects such as cancer, allergies, reproductive and endocrine disorders.

Simulations of simulink models using Kalman filters are often very time-consuming. This problem depends mainly on the fact that the Kalman correction has to be performed at each sample instance through the whole simulation. The goal for this thesis work is to reduce that time-consumption for the filtering part (the integration partis treated in a complementary report) of a simulation. Furthermore a Matlab routine to perform parameter tuning and finally a graphical user interface is developed.The filtering part of the simulation in this thesis is based on an Extended Kalman Filter (EKF). The time optimization of this filter considers searching for the possibility to replace the today?s existing Matlab functions that is used to perform the filtering calculations.

Arbetarstadsdelen Hagalund i Solna byggdes vid förra sekelskiftet och kom tidigt att anses förslummad men har sedan kåkstaden revs på 1960-talet omladdats till kulturhistorisk idyll. Som ett led i miljonprogramsbebyggelsen under tidigt 1970-tal byggdes nya Hagalund vilken snart kom att betraktas som nyslum. Mitt syfte är att analysera olika beskrivningar av gamla och nya Hagalund och undersöka varför en stadsdel kom att stämplas som ful, farlig och olämplig av utomstående men av de boende kom att upplevas som modern, trygg och bekväm. Jag har intervjuat arton personer som bor eller har bott i stadsdelen Hagalund och fått deras sense of place av sitt Hagalundsboende. Flera av familjerna har varit stadsdelen trogna i över 30 år och är in place med Hagalund.

This paper discusses the world heritage of Falun and its influence on the marketing of Falun as a destination. The reason for this study is the fact that world heritage nominations can lead to an increased pressure on the destination and an increase in popularity for the place. A world heritage is something unique and odd that can be used in the marketing of the destination in the purpose of attracting tourists, company investments and so on. It has been vital for the study to interview people that work with marketing or have important rolls within the world heritage.With this background the study is focused on three major questions:What meaning does the world heritage have in the marketing of Falun?Is the world heritage important for Falun? If yes: For who and why?Which organisations/persons in Falun have the greatest influence on the marketing process?In order to answer or discuss this question there are discussions in the paper regarding the notions of place marketing as well as the importance of a well outlined marketing strategy as a basis for the formulation of a product portfolio and segmentation strategy as well as strategy for developing a strong profile on the market.The answers to the question are relative and can have a different view in the future.

The aim of this study is to analyse how female neopagan practitioners form their identitiesindividually as well as collectively. Using Ernesto Laclau?s and Chantal Mouffe?s discourse theory and Anthony Giddens? descriptions of late modernity and self-identity, I intend toinvestigate my informants? construction and upholding of a meaningful identity and sense ofself. I will also look at how the neopagan movement can be viewed as a phenomenon closely interwoven with the overriding tendencies in our contemporary society. Neopaganism is an umbrella term that is used to describe a number of modern nature religions that take their inspiration from pre-Christian traditions.

The purpose of this paper is to examine how teachers comprehend LUS as a development program, but also how they think about one of the points in the program. The study is based on interviews with five teachers working with ages between preschool to ninth grade.The results show that the development program is splendid, it doesn?t come with a lot of paperwork and it has a humanistic approach. When it comes to point 18a which is the main examination, the teachers mainly agree with each other. They all talk about preunderstanding, reading speed and the amount of literature as the main characteristics to be placed at point 18a.

Abstract The purpose of this work is to investigate children?s perception of Swedish birds. Through qualitative questions there were twelve children interviewed. I showed the pictures for the children of different animals that we discussed but with focus on birds. The children could partly distinguish which of the pictures that represented birds and who did not.

This study focuses on romantic friendship between women in three Swedish novels written between 1836 and 1857: Sophie von Knorring?s (1797?1848) Illusionerna (1836), Fredrika Bremer?s (1801?1865) En dagbok (1843) and Marie Sophie Schwartz? (1819?1894) En fåfäng mans hustru (1857). Also, the connection between women and passion as well as the interesting occurrence of step- and foster mothers is looked upon in the study.The romantic friendship is freely expressed in these novels; love between women is neither presented as unnatural or unchaste. It both challenges the heterosexual matrix? claim on intelligibility and its rules for how desire should be expressed.

In recent years there has been a growing interest directed towards focusing on the importance of clear evidence for interventions in social work. To enable the measurement it?s necessary to develop concrete models with manuals on how social work should be designed. Evaluation of the benefits is made in relation to how well the method can detect evidence of clear measurable results. When measuring the result it?s of importance to emphasis on pre and post the situation, not the situation where social work takes place.

In this essay I aim to examine how the landscape of Mönsterås might have looked like during the Bronze age in order to get a better understanding of the house urn that C J Ekerot found in a cairn in Fälle. Mönsterås is an area which has a quality of permanence, from Stone Age to Iron Age with its culmination during the Bronze Age. I will discuss the use and symbolic meaning of the house urn. The house as a symbol during the Bronze Age seemed to have had an important place in the cosmology. I will also discuss the importance of cairns, especially in the archipelago areas.

This is a study of the novel Mes mauvaises pensées (2005) by the French writer Nina Bouraoui. I use an intertextual comparative method, where I read the novel against three intertexts: Marie Cardinal Les mots pour le dire (1975), the David Lynch movie Mulholland Drive (2001) and novels and photographies by Hervé Guibert. Main focus is on the relation between body and language. Using the psychoanalytic theories by Julia Kristeva I examine the melancholy of the narrator in Mes mauvaises pensées. The melancholic subject mourns a Thing which is the unrepresentable archaic mother.

This master essay deals with the changes in the use of and the abandonment of the Avebury monument and the change of the surrounding landscape during the late Neolitihic, about 3000 B.C, and into the Bronze age, about 1500 B.C. The change in the way people supported themselves, the development of agriculture, brought along many other changes as well. I am in this paper dealing with these issues, how and what lead up to these changes, the peoples own part in the development, and I am also looking into the fact that these changes might not have meant an end of old ideologies, but rather a development in the expression of beliefs where the monuments of the neolithic no longer had a place in society..

The purpose of the study was to look into the subjects which the students express when they cry out to their recreation instructor, if there are similarities and differences in the subjects when they turn to their recreation instructor or when they instead turn to their teacher, which different roles and positions the students place their recreation instructors and the teachers in. I have used focused observations during three days in two different schools. Using the ideas of J.Butler on performative perspective, I´ve analyzed the way the students have positioned their recreation instructors and teachers through speech and actions. My conclusion is that students early on see hierarchical structures in school and help maintaining them..
