Toxic metals contaminate soil worldwide and thus serve as sever environmental threat. Therefore the purposes of this study were to investigate in which soil fractions that different heavy metals (Fe, As, Cu, Zn and Pb) could be found in contaminated soils and if it is possible to use sieving as a method for decontamination. Soil samples were collected from three different locations, the Nasa silver mine, the Blaiken-mine and Svalget environmental station. The samples were oven dried and later on sieved into six different fractions 8mm, 4 mm, 0.5 mm, 0.250mm, 0.063 mm and <0.063 mm. The fractions 4 mm, 0.5 mm and <0.063 mm from each location were analyzed in an x-ray fluorescence detector.

The aim of this study is to examine how the Swedish writer Aurora Ljungstedt describes relations and desire in her En jägares historier, and what political message she tries to send her audience through that description.I have applied Eve Kosofsky Sedgwick?s theory of erotic triangles to the relationships in En jägares historier and found that they are structured in the way Sedgwick describes. The structure works to uphold and, when needed, re-establish patriarchal order in the book. Most female characters in En jägares historier are ? also in line with Sedgwick?s theory ? no more than articles of trade between men.

The general purpose of this dissertation is to study picture communication in picture books and it addresses the following questions:What is the illustrator?s role in the process of making a picture book? What communicative qualities do pictures have in picture books and how do pictures interact with texts? What methods do illustrators use to visualize the meaning of stories in picture books?A genre analysis, a literature study and an interview of a professional illustrator has been conducted to answer the questions. I found that all objects that make up pictures, the arrangement, colours and shapes contribute to the meaning in diverse ways. Pictures also communicate in a different way than texts. An important difference between pictures and texts in the context of picture books is that pictures are more open for interpretation.

Looking at the debate on nuclear power in Sweden, the issue of risk is central to understanding the difficulties in resolving differences between proponents and opponents. I sought to answer the research question: "how is the concept of risk constructed in the nuclear power debate in Sweden?" Four main aspects of risk construction were defined and investigated to identify differences between sides in the debate. Through a qualitative study of the debate and its actors I found clear differences in respect to all four aspects of risk construction. First, the perception of nuclear power as a "normal risk" is common among nuclear opponents in contrast to a largely probabilistic view among proponents.

The purpose of the study was to investigate how young female Kurd immigrants experienced their existence between two different cultures, namely Swedish compared to the immigrants parents culture. How their experience behavioural conduct between the opposite sex before marriage and if the young female Kurds thought the mass media picture of them was thought of as a correct image of their lives in general or whether they experienced it as a generalisation only. We chose qualitative methods for our study and used suitable literature based on the theories of this subject to be able to understand the problem. To go deeper whit the study five young female Kurds aged between eighteen and twenty years were asked if they would participate in an interview on the subject. These participants proved that they had no problem at all being multicultural.

In this report listed buildings, according to the Swedish Heritage Conservation Act, have been studied with a focus on cases where economical compensation has been given to the owner of the building and cases where the listing of the building has been appealed by the owner. In order for a building to become listed it needs to be particularly valuable from a cultural and historical standpoint. The listed buildings are protected through a list of regulations that determines which parts of the building can or cannot be changed, what methods and materials should be used for changes and repairs, and how the building should be maintained. These regulations should as far as possible be formulated in agreement with the owner, but a building can become listed against the owners will. To decrease the damage this causes the owner he can in some cases have the right to economical compensation. There is also a possibility for the owner to appeal the listing of the building.

The aim with this study is to examine how students and teachers value source criticism. Partly, this regards how teachers practice this in their teaching and how students work with it during lessons ? but also how students value source criticism in situations where the teacher not has pointed out that this topic is part of the actual assignment. Moreover, there is a focus on investigating how students who are critical of the sources take this into account in their daily lives; for example, when they surf on the Internet or when they discuss news articles or other media. This essay is based on interviews with students and teachers, using a qualitative method. The results of this study show that both students and teachers find source criticism to be of major importance.

The purpose of this essay is to examine how same-sex couples experience the second-parent adoption process. To assist us, we have used our questions: how do the couples describe their experiences of the adoption process? Which are the couples? stories about the experience of contact with the involved professionals? What are the opportunities and barriers for same-sex couples to start a family? How do the couples describe their experience of reactions from the community and society, and how do they think the future will look like for same-sex couples? This study has been achieved through a qualitative approach. The empirical data is based on seven semi-structured interviews with same-sex couples or pair members that want to or have had a second-parent adoption. The theory we have used for analyzing the results is phenomenology with focus on queer theory, heteronormativity, and power.

This bachelor thesis discusses firefighting and the use of portable fireextinguishers in the salvageof historic artefacts focusing on textiles. It also looks into the use of multi-purpose dry chemicalextinguishers in a textile context and the impact the actual dry-agent has on textiles afterfirefighting.Literature studies, interviews and tests on different textiles were carried out to write this thesis.During the tests textiles were exposed to the dry agent and also to dry agent plus water toinvestigate the difference in residue. After vacuumcleaning it was clear that when the textile wasexposed to dry agent and water it was almost impossible to remove the chemical without rinsingin water.By examining the residue left on the textile using SEM it was possible to see if a textile was aswell decontaminated after vacuum-cleaning as it looks to the eye. We know that the dry agentoften consists of ammonium phosphate which acts corrosively on many materials and one canassume it damages textiles as well after longer exposure.Buildings housing cultural collections are vulnerable as we cannot easily replace ruined materialwith new.

As the globalization of companies increases day by day, the need for a clear and comprehensible legislation to overcome the problems with transfer pricing transactions increases as well. Incorrect pricing in transfer pricing situations between companies with close economic ties to each other makes countries risk parts of their taxation income.Swedish legislation uses the internationally accepted arm?s length principle to regulate the transfer pricing transactions. Through the correction rule, the rule is upheld that the pricing between two companies with close economic ties to each other must apply to the same conditions as it would have been if it was between two companies without close economic ties to each other.To ensure that enough material is provided to base the assumption whether or not the correction rule has been followed or not, Swedish legislation provides a number of paragraphs to regulate the matter. The legislation is spread all over and is hard to interpret.
