Periods of hypoxia are a recurring issue in Brunnsviken. Main factors that trigger hypoxia in Brunnsviken are eutrophication  due to anthropogenic emission of nutrients, stratification in the water column due to salinity and temperature differences  that prevents mixing and a sill inlet that prevents water exchange. As an attempt to improve the oxygen levels, bottom water is pumped from Brunnsviken causing aerated surface water to flow back into the basin.  The objective of this Master?s thesis was to study the change in dissolved oxygen levels due to pumping.

This thesis is an investigation of Bosnian immigrants and their use of libraries in Borås and Anderstorp. The purpose of the thesis is to investigate if people from Bosnia read in their mother tongue Bosnian and if they read in Swedish too. The essay is based on questionnaires concerning both young and older immigrants' reading and library habits. The survey encompasses 30 Bosnians. In the theory I have described relevant literature and confirmed the importance of identity, language and culture for immigrants.

During the last years around 100 000 immigrants have arrived to Sweden, people with different reasons and different goals for settling down in Sweden. The reason for immigrating to Sweden that will be dealt with in this thesis is following immigration, i.e. when someone moves here because they have relatives living in the country.The reason why it is interesting to study following immigration is that it is an affecting factor for how many that will immigrate to Sweden the following years and may then be used to make a forecast, based on how many first time immigrants there are. To be able to investigate the following immigration analyses are made with time series, logistic regression and Poisson regression. An ARIMA-model has been used to estimate the number of following immigrants in the future.The other part of this thesis will inquire the matter how inclined immigrants are to become Swedish citizens, whether they even apply for citizenship and also how long time it takes from the time when they fulfil the conditions for Swedish citizenship until they apply.

Predation is one of many factors that form the structure of the macroinvertebrate community in lakes, wetlands and watercourses. Earlier studies lack an examination concerning how fish- and waterfowl predation affect macroinvertebrates during shorter periods in the spring. I performed an exclosure study in the shallow eutrophic Lake Tåkern which is located in the western part of Östergötland County, Sweden. The experiment was performed during a three week period (1-21 April 2012) when the water temperature was low and the density of migrating diving ducks was high. The experimental cages used included three out of four different treatments; general predation (open cages), bird exclusion (net with mesh size 90*45mm) and no predation (net with mesh size 1*1mm).

Cannibalism can have major influence on fish population dynamics. A prerequisite for cannibalism is that the cannibal and the potential victim meet, and besides density effects, the encounter rate between cannibals and their victims is therefore also largely dependent on habitat use and habitat heterogeneity. In this study I quantified and compared the potential for cannibalism in stream-dwelling European grayling populations in three rivers in Jämtland by means of habitat classifications. I also analyzed population dynamic consequences of varying the potential for cannibalism in terms of intensity, using a physiological structured population model. Findings based on habitat characteristics were that the potential for cannibalism is in general not favourable in these types of streams.

The purpose of this essay is to illustrate immigrants? and refugees? thoughts and experiences of the process of integrating into Swedish society and to examine which social networks foster the process. The main questions in the study are: * What experiences enable refugees and immigrants to become integrated and fully participating members of the Swedish society?* What is the importance of the social networks with regards to integration into Swedish society? A qualitative method was used and five interviews were completed with SFI (Swedish for immigrants) students. The study shows that knowledge of Swedish language promotes an initiative in contacting native Swedes, and it also determines the success of integration.

Urban density is not new, but rather one side of the continous processes of change underway in the city. During the urbanizing boom of the industrialization, when the cities grew bigger, the first spaces to be built on were vacant and planted areas in the interior of the district. The gardens that once were there were replaced by yardhouses. The idea of urban density is that a dense city means less distance between residential areas and workplaces, resulting in fewer shipments and travelers, which ultimately leads to lower energy consumption and lower emissions. Urban density may lead to shorter distances, but not necessarily. In the wake of urban density the greenstructures of the city is shattered. The possibilities for green areas to contribute to the health of the city and its inhabitants is dramatically reduced.

AbstractWhen immigrants move to Sweden from their native country it is not unusual that they experience some kind of identity crises. Their own experience of their cultural identity can be very problematic and they often lose a part of what they previously saw as their own identity. To handle such crises the immigrants can use different strategies. They can for example accept their disparity, deny it or emphasize it. The aim of this study is to examine how immigrants in Sweden experience that their cultural identity has changed since they moved here from a country that has a culture that is different from the Swedish culture.

The purpose of this study was to explore the experiences of being a homosexual immigrant in the Swedish society. Our questions were how the interviewed homosexual immigrants experience being treated by the people in their surroundings and how they are influenced by their attitudes. We also wanted to know what kind of thoughts they have about affiliation considering origin and sexuality, and what positive and negative aspects they experience from the combination of being both homosexual and immigrants.To get the answers to these questions we used a qualitative method and interviewed seven homosexual immigrants between the ages of 25 and 40 years. We then compared our material with earlier studies of the living situation of homosexual immigrants in Sweden, Denmark and Norway. We also linked our findings to Goffman's stigma theory and to heteronormativity.The main result was that the combination of homosexuality and immigrantness can result in various difficulties.

SammanfattningSyfte och frågeställningar Syftet med denna uppsats var att undersöka hurvida en LCHF (Low Carb High Fat) kost skulle kunna vara en hälsosam livsstil utifrån hur den påverkar olika hälsomarkörer hos normalviktiga personer där en viktminskning ej har eftersträvats. Frågeställningen var följande: Hur påverkar en LCHF-kost med maximalt 30 gram kolhydrater per dag under 3 veckor normalviktiga kvinnors BMR (Basal Metabolic Rate), blodlipider, blodglukos, blodtryck, kroppssammansättning, midje- och höftmått samt deras kroppsvikt?Metod En experimentell studie har genomförts på 8 normalviktiga kvinnor mellan 20 och 35 år. Samtliga försökspersoners BMR, blodlipider, blodglukos, blodtryck, kroppssammansättning, midje- och höftmått samt kroppsvikt mättes vid normala levnadsförhållanden innan studiens start samt efter 3 veckor av en strikt LCHF-kost med endast 30 gram kolhydrater per dag.Resultat BMR sänktes i genomsnitt med 4,4% vilket var signifikant (P<0,05). HDL (High-density lipoproteins), LDL (Low-density lipoproteins) samt totalkolesterol höjdes signifikant (P<0,01) med 21%, 25% respektive 22%.

The purpose of this essay was to analyze if and how teenagers think about immigrants and Swedes, the relationship between them and to find out where these thoughts originate from. The essay consisted of four main questions; do the teenagers think in terms of immigrants and Swedes? How do the teenagers reason in terms of who is an immigrant and who is Swedish? What do they think about the relationship between immigrants and Swedes? Where do these opinions originate from?The study was based on eight interviews conducted with teenagers born in 1987. Our conclusion of the study was that it is not easy to determine who is Swedish and who is not. It was clear in this study though that looks and behaviour were utterly important.

The aim of this essay was to acquire an enhanced knowledge about young immigrants? point of view of integration. During a former practical training semester I became interested in what the young immigrants thought about their own integration, what their conception was about this issue. I found that it had different meaning to different persons, to some it meant assimilation, to others it meant being able to interact with the opposite gender. To examine this I used interviews and interviewed an amount of young immigrants in different stages of their studies in Swedish.

The cat has evolutionary become an obligate carnivore. Today it is common to feed the cat a dry food. Studies have shown that the dry formula can have negative consequences for the cat. A literature study where conducted to investigate whether the cats origin makes it incapable to compensate for the changes a dry food entails. The impact and implications regarding water intake, energy intake and blood glucose concentration when feeding the cat dry food where examined.

This thesis focuses on the problems involving immigrants and their voting behaviour in Sweden. We presuppose that immigrants vote in a far less extent than Swedish citizen according to general statistics. We try to explain and give solutions to this problem. To our help we use both integration theory focusing on multiculturalism and electoral participation theories.Starting off in these two theories, we have further analyzed a number of policies issued to solve the participation dilemma. The policies were issued in order to elevate the socio-economic standards, inform citizens and close the distance between voters and politicians.Our results show that what work best is long term ventures aiming at integrating immigrants to the Swedish society.

The aim of this study is to go into depth and analyze the identity ?immigrant? (invandrare) and how it is constituted in Dagens Nyheter, Svenska Dagbladet and Sydsvenska Dagbladet. An investigation (SOU 2006:21) by Swedish authorities concludes that immigrants are portrayed in an unfavorable way in Swedish media, whilst Gunnar Sandelin in a debate article in Sweden?s biggest morning newspaper (Dagens Nyheter) meant that Swedish media lies about immigrants, creating an image of them that is too favorable that is not in touch with reality. This gives this thesis momentum to further investigate the identity immigrants are given in Swedish media.The theory and method used in this thesis is Laclau?s and Mouffe?s discourse theory.
