Löslighet och transport av sällsynta jordartsmetaller i Källfallsfältets gruvsandsmagasinHugo de Campos PereiraSyftet med detta arbete har varit att kartlägga vilka mekanismer som styr lösligheten av sällsynta jordartsmetaller (eng. rare earth elements, REE) i sulfidhaltig anrikningssand vid den föredetta gruvan Källfallsfältet i Västmanland. För syftet har markvatten- och grundvattenprovtagning utförts, tillsammans med laktester och geokemisk modellering med Visual MINTEQ ver. 3.0.Resultaten visade att sulfidvittring är den främsta processen som styr pH i anrikningssanden, och därmed också indirekt REEs löslighet. Däremot är sulfidvittring ingen källa till REE i sig då ämnena inte föreligger sulfidbundna, något som oxiderat tillgänglighetstest NT ENVIR 006 visade.

The aim of this study is to combine queer theories with quantitative methods. In social sciences, queer theories are being widely and increasingly used. Quantitative method is also widely used, and as a traditional method it can be regarded as a cornerstone in social sciences, sociology in particular. However, the two perspectives, queer theories and quantitative method, seem at a first glance to be very different in their understanding of social phenomena. Queer theories have, with some exceptions, mainly focused on qualitative research concerning such phenomena as sexuality, while the field of science is quite diverse.

This essay is a qualitative study of the Swedish joint-stock company Svenska Spel AB?s television commercial from 2008. The commercial is called ?Spela lagom - When I grow up?, and is meant to serve as an informational commercial about being underaged in situations regarding gambling. Using semiotics and rhetoric?s, we are analyzing how elements seen in the commerical affects the rhetorical situation the clip is bound to; how the marketing is done to enhance Svenska Spel?s brand; and what strategies are used to make sure the public service announcements regarding persons involved with underage gambling gets acceptance.

The purpose of this study was to increase the knowledge and understanding of what impact support-groups, such as represented by Qvinnoqulan, can have on women with drug-addiction. The questions at issue for the essay was: How does a selection of women who participate in Qvinnoqulan describe their thoughts, experiences and reflections of the group? What sense has Qvinnoqulan made for the women on a personal level and for contributing to live a life without drugs? To answer the questions a qualitative method was used and five interviews were made with women who participated in the activities of Qvinnoqulan. To analyze the data a social constructionist perspective and an empowerment perspective was used. The result of the study showed that the women were in the process of rebuilding a new life without drugs and reconstructing a new identity.

Our digital society encompasses nowadays different channels, which includes social media where many users consider it as a platform where they can fetch news or exchange news and information. This leads to a large spread of news exchange in a very fast speed, which involves the global users within social media to be a part of this social interaction. This study is focused on how Twitter affects the usage of the user?s news consumption. By reaching out to our specific target audience, which includes Twitter users in Sweden, we made a web based survey with a content of relevant questions.

This is a thesis on D-level. In a previous course, at our program Computer Science, we came up with an idea of how to improve/complement training for new employees who are situated in a stressful workplace at companies who are in a constant need of rehiring. We developed this concept and came up with an idea for a simulator that could train staff as well as relieve stress and tension for new employees. The idea matured and became a Serious Game simulator based on a dual-wield Wii-controlled PC-based simulator with Bluetooth support.The purpose of this paper is to produce a design concept for a simulator as well as conducting research on the topics: mental and physical learning abilities, psychomotor abilities, visual perception, hand-eye coordination, confidence, simulators and Serious Games. The conducted research will be the foundation for the design concept which will be implemented in our co-workers', Henrik Djerf & Daniel Gomez-Ortega, prototype.

Reaching out with a specific message to consumers is the idea of marketing. Advertising is among the most common elements when it comes to marketing a product or a service. There are various ways to provide marketing with a message. A relatively new way that has become larger in marketing is to provide marketing with emotions. It has been shown in several studies that emotions can have a direct or an indirect effect such as ad-attitude and brand-attitude, and that is what our essay is about.

This thesis investigates the dynamics of the relationship between a leader and the followers within a chosen organization. The research on leadership has generally been focused on the leader, and consequently treating the followers like passive subordinates. We pursue a more multidimensional view of the subject, meaning that leadership descends from an interaction between leaders and followers, which makes it relevant to study the dynamics of the relationship from both perspectives. We chose to do a qualitative case study on a middle- and preschool which has won a price for being an ideal place to work at. This price peaked our interest to investigate why the relationships are highly functional in this particular organization.

The objective was to examine the frequency of unwanted behaviors in the Swedish feline population and what factors in the environment, inheritance and past life that have an influence on the frequency. SLU?s web poll generator was used to create a web poll which insinuated that it was a poll with objective to make an inventory of the Swedish feline population. I wanted to avoid that only owners to cats with unwanted behaviors answered the poll. The web link to the poll was sent to SLUs students and posted on Internet forums for people interested in cats.

Since the disintegration of the Soviet Union a lot of hope has been put on civil society to help develop Russia into a more democratic society. This study explores the constructive elements in the relationship between civil society and the state in Russia, and how this enables the work toward political development. By using Julie Fishers theory about political development and organisational autonomy I discuss the varying and often complex ways in which civil society and the state interacts. These are often not mentioned in the liberal tradition, which believes that civil society's most important democratic function is to act as a watchdog for the state.There is very limited political space for NGO's in authoritative Russia. The existing oppositional NGO's are important for the political development, but they are few and their impacts on society are limited.
