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.

Objectives: The aim in this thesis has been to generate information relevant for strategic positioning and future evaluations within the scientific field of sport and exercise psychology. This has been done by request, and in collaboration with The Group of Sport and Exercise Psychology at the Institution of Psychology at the University of Umeå.Research questions:  (1) How does the cognitive structure within the field of sport and exercise psychology take shape with respect to research topics in current sport-psychological research, i.e. the research front? (2) How does the social structure within the field of sport and exercise psychology take shape with respect to formal scientific collaboration?Data: 879 articles published between 2008-2011 were used in this study. The population of articles were collected from a set of 5 core journals: International Journal of Sport Psychology, Journal of Applied Sport Psychology, Journal of Sport and Exercise Psychology, The Sport Psychologist, Psychology of Sport and Exercise.

This essay explores how artwork in the public space can be analysed, conceptualized and described by bringing attention to site. Through an analysis of artworks in the yearly art exhibition of Fittja Open 2011, the essay draws attention to site-specific art and structures of power. The principal aim is to present not only the exhibition of Fittja Open 2011 but also other artwork in the public sphere in Fittja, a suburb to Stockholm. From this point of departure other interests evolve that concerns the "image" of Fittja. The analysis, based on research in art history, architecture, ethnology and philosophy as well as qualitative interviews, also focuses on understanding the role of site and the relations between art practice, institutions and site.The result shows that there are problems with a ruptured interface between the artwork and site.

The New National Elevation Model (NNH) is a new high-resolution digital elevation model (DEM) of Sweden from airborne laser scanning. It creates many new opportunities, particularly in the area of flood mapping. NNH is provided by Lantmäteriet in two formats, both in raw LIDAR (Light Detection and Ranging) data and in grid format with two meter resolution. These alternatives have advantages and disadvantages and the aim of this thesis research is to identify these. One of the focuses of the study is data storage and thus data structure analysis, resolution and storage facilities. The research questions are:Why and in what context the different NNH-products from the National Land Survey are used (DEM 2+ or point cloud)?What constraints and opportunities are created by the different options, mainly in terms of different software, resolution, and data storage?The study area is Kärsön in Ekerö municipality located in Stockholms län and has an approximate area of 25 square kilometers. The study is divided into two parts. The first objective is to identify the consequences of using different software to create DEM from pointcloud compared to the DEM2+ model. Height models with a two meter resolution are created in FME and ArcGIS. The models are then compared with the grid from Lantmäteriet, created in TerraScan. The second objective is to examine the impact of the change in resolution, both the storage aspect and both the accuracy aspect. Inverse Distance Weighted (IDW) is an interpolation method which in previous studies proved to have the best results on high resolution LIDAR data. This model was tested and compared with a model from FMEs built-in function and the model from Lantmäteriet wich are based on triangulation (also proved a good method in previous studies). The grid created in TerraScan has good properties such as accuracy.

Purpose: To contribute to the understanding of the relationship between private labels and the retailer brand in grocery retailing. Methodology: We use structured interviews as a cross-sectional method for quantitative data collection. The existence of the relationship is tested through correlation analysis and regression analysis. Theoretical perspective: Perceived quality of private labels and of retailers are the main theoretical concepts for this thesis. Additionally, we introduce the concept of loyalty to show the benefits of a positive consumer image.

Syftet med denna studie är att förklara varför konsumtionen av ekologiska kläder haft en svag ökning sett utifrån konsumenternas perspektiv.

Inadequate data quality has a negative effect for organizations, however utilization of modern technology and data analysis may shape new values for organizations. Our research has found that the quality of information in field reports for error reporting varies significantly. In many cases, the information in the field reports are deficient in such way that the field report need additional information from the sender, thus risking prolonging lead times in the error reporting process. More efficient use of information has become possible with today?s technology.

Compared to all existing ethnic groups in Sweden, the integration of Somali women has failed the most within the aspect of employment. This bachelor?s thesis investigates the obstacles in the integration of Somali women by focusing on one case, a project named ?Kvinnokraft?, partly financed by the European Socialfund.By interviewing eight key actors, opinions about obstacles in the project have been identified. A theoretical framework that incorporates integration, project research, multi-level governance and intersectionality contributes to explaining difficulties in integrating Somali women.The empirical findings show that there are individual, social and institutional holdbacks. Stereotypical perceptions were common amongst officials, which contributes to a creation of an inferior position in the structures of the society for Somali women.

The aim of this study is to point out variations of practices in the relationship between professionals of service occupations and their clients. The material consists of four openly conducted thematic interviews with male professionals who work in the environment of their clients' homes.The main theoretical approach of this analysisis undertaken with ethnicity in mind.The practices identified aim to throw light on the boundaries between the differing cultures of professionals and their clients.The analytical termsboundary reduction and boundary maintenanceare used in this research.The two-stage analysis points out different practicesused, in chronological order, during contact between professionals and their clients. This is followed by a statement of the themes which connect, primarily fromthe professional perspective. The results indicate an intimate connection between intercultural and transcultural aspects through the use of cultural transparancy, which is a strategy connecting different roles, aswell as use of loophole tacticsthat afford the possibility of definingspace, place and relationship.It's illustrated how the professionals operate from "within the structures and worldview" of the client, and this analysis also reveals a glimpse of the potential for cultural changein the meeting between different cultures..

The objective of this thesis was to present a design proposal on a modular mechanicalstructure for a nanosatellite. The size of the structure should follow the CubeSatstandards. This standard divides satellites in units (U), where 1U is equivalent to acube where sides measure 100 mm. 2U corresponds to the same volume and size as2 assembled 1U structures, and so on. The focus was to develop a structure in theorder of 3U and 6U.At the integration in the satellite launch rocket, there are a couple of differentinterfaces, where the structure is adapted to common ones; P-POD and CSD.

The purpose of this essay is to investigate the melancholic, poetic language in Bübins unge (Bübin´s brat) by Mare Kandre (1962 ? 2005). In my opinion the novel, which is about a teenage ritual, also gives an imaginary arena for archaic and unmentionable experiences of the libido. It is therefore a witness to the truth of the subjects complex mind. To my assistance I have Julia Kristeva´s theory on the abjection, the successful melancholia and her concepts of the outsider and the catharsis.

Bakgrund och problem: Fastigheter och fastighetsföretag har med jämna mellanrum blivitaktuellt, ibland ser man att de agerar till synes olika. Det vore intressant att såförutsättningslöst som möjligt studera vad ett antal av de svenska fastighetsföretagen gör.Ett sätt att göra det på kan vara genom att ta del av deras årsredovisningar ochsammanställa informationen som visar vad man har gjort samt hur företaget är strukturerat isyfte att underlätta för fortsatt studier av företagen. Det har utmynnat i följandefrågeställningar:Vad gör ett antal av de stora svenska fastighetsföretagen?Samt:Hur kan man gå tillväga för att använda insamlad data i vidare studier för att beskrivaföretagen?Syfte: Att ställa upp informationen på ett sätt som gör att läsaren kan skapa sig enöversiktlig bild av ett antal företags struktur samt beteende under 2009. Att samla in ochställa upp data som ett underlag i syfte att bereda för fortsatt forskning.Avgränsningar: Studien omfattar endast svenska stora fastighetsföretag vars primäraverksamhet är att äga och förvalta fastigheter.

This thesis deals with the issues of participation and influence in the multicultural society. The aim with the study is twofold, first to identify determinants improving participation and influence in this context, and second to see if the ecouragement of a strong civil society in ethnic segregated areas is a possible way forward to a multicultural democracy. This is conducted through a case study of brobyggarna in Malmo, Sweden, and how they as an integration policy is working with these questions. Six qualitative interviews have been conducted with seven persons workning as brobyggare or in close connection with them. Toghether with readings of earlier research this material is analysed through an eclectic model with theories put together in five analythic dimensions, Multicultural democracy, Social milieu, Unequal possibillities to participate and influence and Local powerstructures.

WordPress är ett av världens mest populära Content Management System. Eftersom det har en hög popularitet drar det till sig uppmärksamhet från personer och grupper som av olika anledningar vill utnyttja säkerhetsbrister på webbsidor. Syftet med denna uppsats är att testa säkerheten i olika tillägg till WordPress som externa utvecklare skapat eftersom dessa inte genomgår någon obligatorisk säkerhetskontroll. Insamlingen av data skedde via ett utförande av statiska tester på några utvalda tillägg. Denna teknik grundar sig i en granskning och analys av dokument i form av text, modeller eller kod.
