Utvärdering av den biologiska reningen av processavloppsvattnet vid GE Healthcare i Uppsala
GE Healthcare operates in Uppsala (Sweden) and develops systems, equipments and medium to purify medical substances. Discussions with the local authority concerning planed far-reaching changes and upgrades of the biological process techniques for sewage management, aroused the question about revising the terms of permit for the activity. Therefore it seemed necessary to evaluate a newly installed biological process technique, which is the background of this thesis. The evaluated biological treatment process was built in 2003 and consists of a biological reactor filled with moving bed carriers with a high surface area for biological growth. At the time of the project the biological wastewater treatment plant consisted of a flow equalization facility and two following parallel biological processes; a biological reactor with moving bed carriers and a tower trickling filter.The aim of this thesis was to survey the function of the biological reactor with respect to the reduction of organic matter.
Löslighet och metylering av kvicksilver i en förorenad sjö (Ala-Lombolo) i Kiruna kommun :
Transformation of inorganic mercury (Hg) to methyl mercury (MeHg) is a biotic process that is proposed to be conducted primarily by sulphate reducing bacteria (SRB). The formation of MeHg is of great interest because it is the mercury species that biomagnifies to the greatest extent in the aquatic food webs; about 90 % of all Hg in fish is MeHg. Our understanding of factors involved in the production of MeHg is very important for making a reliable risk assessment. The purposes of this study were to investigate the different factors that control the solubility of Hg and the production of MeHg in a contaminated lake sediment.
The lake Ala-Lombolo, Kiruna municipality, is well-known to be contaminated by mercury from different sources. Sediment cores were sampled at three different locations (N, SW and SE) in the lake and divided in three different layers; 0-5, 5-10 and 10-15 cm.

Konstruktionen av Amerika : Om objektsbildning och hur objektet Amerika skapas i två historieböcker för gymnasiet
The aim of this essay has been to show how the object America is constructed in two of the most used history books in Swedish high school. The theoretical framework used in this paper is based on the post-structural discourse analysis as presented by Michel Foucault. More specifically can be said that Foucault´s theories about formation of objects have been used as a tool to show how the image of America is constructed in the books. Later this paper also discuses which subject positioning the studied books take, also this inspired by Foucault´s theories.The study is presented with long quotes from the studied material to reach a transparency that enables the reader to see which dictums the conclusions are based on. This also makes it easy for the reader to judge whether or not the conclusions are reasonable.
Betydelsefulla faktorer som bör ingå i en marknadsföringsmix för modeprodukter till barn
In a society where children are getting a bigger influence over the family?s consumption and where more products for children are purchased, the market for children products has expanded. This growth is due to a higher amount of older parents which have a god economy and are choosing to spend more money on products for their children. Also the fact that parents use fashion products for children as a way to reflect their own status and that children are becoming more fashionable and aware of trends have contributed to the markets expansion. All together this leads to a grown importance of knowledge for marketers concerning the market.
?Vi kan bli ett Barbielag!? : En studie om yngre barns sociala relationer och identitetsskapande i ett postmodernt konsumtionssamhälle
One of the main goals in this study is to investigate how young children's identity formation and social relationships are depicted by today's consumer society. In order to reach the goals of the study I also concentrated myself on questions regarding the reflection of symbolic aspects consumption in younger children's interaction and preschool-teachers' ideas about how and in what ways children's consumption patterns are created and developed nowadays. In order to answer the presented research questions I used the theoretical arguments of researchers in the field of pedagogy Gert Biesta in connection with the ideas and concepts of the consumer society characteristics developed by the sociologist Zygmunt Bauman.The thesis' methodological approach consists of a combination of semi-structured interviews with teachers and observations of children's interaction, which contributed to a systematic investigation of the thesis' problem area and served as a tool for obtaining answers to the research questions.The results demonstrate that consumption occupies a lot of space in young children's lives, which means that it greatly affects their social relationships today. Both consumption and knowledge of the known brands prove to be the child's path to the desired community on the one hand, and the children's way to the consumer world on the other (hand), which in turn points to an obvious dependence between children's consumption and their social relationships.The results also show that there is a tension between the perception of identity formation as preschool-policy-document on the one hand and the attitude of the identity prescribed by consumer society norms and regulations on the other..
Varför bildas politiska partier? : En studie av Sjukvårdspartiet i Värmland
AbstractWhy do Political Parties emerge? ? A Study of "Sjukvårdspartiet i Värmland"Political Science, Johan UtterThe political parties have important roles to play in contemporary society. They act as bearers of power and presents the voters with finished packages of ideas on how society should grow, develop and change.

Many theories have been developed over the years concerning matters related to political parties, but one area of research remains largely unexplored, namely the topic on why political parties do emerge in the first place.
Spatiella mönster och lager av organiskt klor och klorid i barrskogsjord i sydöstra Sverige
The concentration and storage of organic chlorine and chloride were determined in soil, to a depth of 40 cm, in a coniferous forest in the Stubbetorp catchment area in south-east Sweden. Also, the spatial distribution of the two forms of chlorine was determined. Soil samples were collected at 49 of the nodes in a grid with approximately 105 m between the nodes. The analysis of spatial variability suggested that no spatial autocorrelation was present either within the variable organic chlorine or chloride. This means that no sample was more influenced by another nearby sample, as compared to other samples further away.
"Flerspråkigheten kan öppna många dörrar i min framtid" : Hur ryskspråkiga minoritetsungdomar i Estland upplever sin flerspråkighet och dess betydelse för identitet
Issues related to multilingualism and its importance to each individual and the whole society are the subject of today?s school debate. The mere fact that the aspects of multilingualism are discussed actively not only in a school environment but even in the mass media and other communities proves that multilingualism is an important and complex phenomenon in our lives.The subject that I have chosen to study into is about the importance of multilingualism for minority individuals and the conditions for their multilingualism. The aim of this research is to investigate the importance of multilingualism for identity formation among several Russian-speaking young people who were born and raised in Estonia, as well as to try to understand the factors that were relevant to these young people's multilingualism and their view on it. Six young people aged 16-19 were considered in this study.
Etniskt diskriminerad i arbetslivet? : En fråga om trovärdighet
Archbishop KG Hammar has attracted attention for his liberal position in theology. His view on the role of language and communication is central in several books and articles he has published as leader of the Church of Sweden. One of his main theses is the fact that meaning is created in the encounter between text and reader. He often reiterates: God is relation. This non-traditional dynamic stance has a broad impact not only on theology.

Stadens offentliga rum ur ett socialt hållbarhetsperspektiv - Jubileumsparken, ett offentligt rum för unga?
The public spaces of the city from a social sustainability perspective, Jubileumsparken, a public space for the young, aims to see how public spaces can be open and accessible to all young people in the community. New public spaces can be created and formed by urban planning. A public space that is undergoing considerable development is Jubileumsparken, which is situated in Gothenburg. This area constitutes the case study for this thesis. Due to the commercialization in the neo-liberal society of today, there is a risk that economically weak people, such as the young, the unemployed or students, can?t take part of all public spaces.
