Water is the most essential resource for life. In cases where drinking water is processed from surface water it is important to ensure the raw water is of good quality, and is suitable for processing through the water treatment plant.The drinking water for Västerås is sourced from Västeråsfjärden, in the western side of Lake Mälaren. The city itself is home to marinas, ports, a wastewater treatment plant, the Svartån outlet, sewage pumping stations and stormwater outlets. Because of the negative effects these activities have on surface water quality, Mälarenergi AB is interested in relocating the raw water intake point to Granfjärden, 10 km east of Västeråsfjärden. At Granfjärden the intake point would be less exposed to the activities in Västerås, and could be placed at a greater depth, resulting in better water quality.In this Master?s thesis the water quality and the pollution risks at Västeråsfjärden and Granfjärden sites are compared.

The overall purpose with this thesis has been to study the strategic development of the Swedish Green Party, Miljöpartiet de Gröna. From its first appearance in the Swedish parliament 1988 to its decision to cooperate with the Social Democrats and the Left Party in 1998, the Greens has gone from a radical antiparty to a pragmatic support party. The analysis has concentrated towards identifying the causal factors behind this strategic move made by the Greens, and to determine how this party change has affected the party's strategic goals. In order to do so, a qualitative case study has been conducted where an integrated theoretical approach has been used. By studying official statements and internal debates the thesis concludes that the strategic change made by the Greens was due to the evolvement of a new dominant coalition of within the party.

The purpose of this investigation is to show how politicians state primary goals and how they break them down into secondary objectives within the sector of Child-and education area. This is supposed to create a general image on how the targeting process is handled within the public activity. Finally, this will lead us to what is necessary for the targeting process to work successfully within the public activity.  We have implemented a qualitative study within the two chosen municipalities. This case study is based on personal interviews that are conducted through semi structured questions.

The purpose of this thesis is to show how to use vulnerability testing to identify and search for security flaws in networks of computers. The goal is partly to give a casual description of different types of methods of vulnerability testing and partly to present the method and results from a vulnerability test. A document containing the results of the vulnerability test will be handed over and a solution to the found high risk vulnerabilities. The goal is also to carry out and present this work as a form of a scholarly work.The problem was to show how to perform vulnerability tests and identify vulnerabilities in the organization's network and systems. Programs would be run under controlled circumstances in a way that they did not burden the network.

A central question is what view of communication is dominating in a municipality in the southern part of Sweden. The study deals with communication theory from two different perspectives; the view of transmission and the view of creation of meaning. Falkheimer and Heide (2003) claim that the view of transmission is one-way communication where the receivers apprehend passivly. In the view of creation of meaning the goal is to develop and strengthen the common notion that exists in a group. Empirical studies were done, that consisted of qualitative interviews with politicians, directors of the municipality, and principals from three childcare and school areas, and also from one upper secondary school.

Lucida drömmar (LD) innebär att drömmaren inser, under drömmens gång, att omgivningen och händelserna runtomkring är en dröm och inger förmågan att kunna påverka och reflektera över händelserna i drömmen. I lucid dreaming treatment (LDT) får drömmaren lära sig att förändra mardrömmars händelseförlopp. Dock blir inte alla lucida och många tror att det är själva känslan av kontroll som ger en effekt. Studien kommer utforska om kontroll utgör en nyckelkomponent i LDT genom att undersöka sambandet mellan LD och locus of control (LoC), depression och subjektivt välbefinnande där LD verkar som en medierande variabel mellan å ena sidan LoC och å andra sidan depression samt subjektivt välbefinnande. Deltagarna (n = 54) i undersökningen har fyllt i formulär gällande frekvens av drömmar och LD samt formulären Rotter?s 29 item internal-external scale, Center for epidemiologic studies depression scale, International positive and negative affect schedule short form, Satisfaction with life scale och Pittsburgh sleep quality index.

When going through a stem cell transplantation a patient is forced to undergo protective isolation to inhibit risk of opportunistic infections related to the low leucocyte count as a result of aggressive pre-transplant chemotherapy treatment. Protective isolation has shown to have an impact on patient experiences during treatment and the aim of this study is to elucidate experiences of protective isolation of patients undergoing hematopoietic stem cell transplantation and to deduce patient perceptions of the role of nurses in protective isolation care. The presented study was performed as a mixed qualitative and quantitative survey at a hematopoietic ward in Sweden. Results were analyzed by Mayring (2000) and by descriptive frequency charts and show that patients in protective isolation experience alienation, necessity, safety and anxiety with regards to their protective situation. Considering the role of nurses patients perceive their role to be attendant, informant and acting as an executioner of medical implementations.

The Swedish forest policies have earlier mainly been focused on two goals: production and environment. The production goal aims to benefit the economical gains from forestry while the environmental goal primarily aims to shield the ecological values of the forest. With the introduction of the Swedish environmental code and the environmental objectives it was made clear that the overall objective for Swedish community development, including the forestry sector, is sustainable development. Sustainable development includes supporting economic, ecologic as well as social values of which the latter seems to have been forgotten in the forestry sector. This was recently brought to attention to the sector and the debate how to handle the social values is now ongoing.The legislator has not been unaware of the social values since they have since long been at least somewhat included in the preliminary works.
