Miljökontoret i Luleå har sedan 1997 gett tillstånd till ett antal minireningsverk i Luleå kommun. I april 2006 fanns det totalt 42 hushåll med minireningsverk. Syftet med examensarbetet har varit att ta reda på vilka typer av minireningsverk det finns i kommunen, hur de fungerar, vad som egentligen kommer ut från anläggningarna och om serviceavtal finns. I examensarbetet finns en litteraturstudie över vad avloppsvatten innehåller och allmänt hur minireningsverk fungerar. De reningsverk som finns i kommunen är från tre olika tillverkare, arbetet innehåller en beskrivning av dessa anläggningar baserat på det material som finns från tillverkarna.

A B S T R A C TTitle: Democracy- Choice of the people or the voice of media? (Demokrati- Folkets styre eller Mediernas Makt?)Number of pages: 36Author: Carolina VallinTutor: Else NygrenCourse: Media and Communication Studies CPeriod: Autumn term 2006University: Division of Media and Communication, Department of Information Science, Uppsala UniversityPurpose/Aim: The purpose with this essay is to discuss which influence media has on the democracy.Material/Method: Qualitative explorative research method is used to see how much space the newspaper Dagens Nyheter gave to the parties represented in the parliament, and compare the results with the numbers the parties received in the general election 2006.Main results: This research showed similar results in the survey made of DN and the numbers the parties received in the general election 2006. Media can?t decide how people should vote in a election, but they can influence what citizens think and talk about by having the power to choose which information that shows on the agenda.Key Words: Dagens Nyheter, Agenda setting, Media, Power and Democracy..

Different Perspectives is a study of detainees' and guards' experiences of the remand prison. The result of the study shows that the remand prison brings forth the individuals anxiety, stress and fear. The individual detained in remand prison have a great need for contact with their families, but also with the guards. In the remand prison there is always a great level of control and always some kind of power practised. It is the guards who have the power and the competences to make the individuals detained in remand prison follow the rules and do what they have been told.

Taking a qualitative approach, this research investigates different theories and methods for creating parks that people will cherish and visit during their daily life. It also takes on the task to understand how principles of developing recreational values in a small forest is affected by the addition of a new element to the landscape, i.e. a major highway. Data was collected through the combination of focused literature review and study trips. This provided a framework which in turn was applied to the subject of the study, i.e.

The interest in small-scale electricity in Sweden has increased strongly in recent years. The interest is noticeable both among politicians to increase the share of renewables in the energy mix, and among electricity consumers to partially replace purchased electricity with self-produced. This has resulted in a significant increase of electricity production in low voltage grids in recent years, and the trend appears to continue in the coming years. The majority of the new production plants are solar cells, followed by wind turbines, and it is also in these the greatest efforts are made in this paper.Distributed generation is often seen as something positive since it will contribute to reduced transmission losses and reduced voltage drop in the networks, and that it increases the share of electricity from renewable sources. In cases where the grids are not strong enough, or in other ways not adapted to manage the installed production, power quality may be adversely affected.

The purpose of this thesis has been to develop a tool for modelling and simulating the nuclear plant Ringhals 3. The model should be used to improve the knowledge on the dynamics of the plant. Ringhals 3 is being upgraded to produce more power and a tool for analyzing the new operating conditions is needed.The work in this thesis has consisted of improving and developing an existing model of Ringhals 3 made with the modelling tool Dymola. The model has been validated by comparing the results of a simulated house load transient with data from the actual plant. Validation shows good agreement with data from the real plant.

The purpose of this study is to develop a general understanding of the areas of alliances and service quality as well as their relation to each other, through a consumer perception. Further, to discover more detailed and close up knowledge of customer perceived service quality within airline alliances. This is done by identifying particularly significant dimensions in the service process that have an influence on the perceived service quality.The thesis is based on qualitative study using a critical incident technique to explore the issue of service quality. In the research of the material the iterative approach has been used. The primary information sources are the interviews with customers-members of airline alliance.

Today in Sweden, apples are mostly cultivated for direct consumption, i.e. dessert apples. Apple breeding aims at developing cultivars with new and improved qualities in order to meet the demands of different target groups and to increase the interest in apples on the market. Different target groups have different views on the qualities of an apple. The consumer, for instance, wants an apple that is tasty and beautiful, while the grower, in addition, wants an apple cultivar that is healthy, has good winter hardiness and a predictable, annual productivity.

The society of today is largely dependent on electricity and the dependence does not show any signs of declining. Reliability of supply will become increasingly important in the future and it is therefore important to investigate factors affecting the failure rates in electrical components.Sweden was hit by several severe storms during the 00?s. As a result of this many overhead lines in forests were cablified. In urban areas underground cable systems have been the norm for many years.

The public sector is a major purchaser of goods and services. By setting requirements for environmental and social considerations in public procurement, an authority has the possibility to use consumer power to influence the actors in a market. The purpose of this paper is to investigate public procurement of textile products in a municipality, in order to gain knowledge about factors that may be important for the use of environmental and social criteria. Håkan Hydén´s (professor in sociology of law) norm model was used as the basis of the analysis, where the conduct was investigated along three dimensions of the norm ? willingness, knowledge and system conditions ? in order to identify underlying factors that can influence the process.The results ? analyzed by using interviews and documents ? show that the procurer's willingness, motivation and knowledge are important factors in this context, as well as the political priority of the municipality.

This study aims to examine play as a phenomena from a phenomenological approach. This I do by discussing a dominant approach to play, an perspective which is reproduced in the context of pre-school and in where the play and learning is in single focus. Using alternative perspective on play, mainly by Gadamer and Bakthtins philosophical thoughts about the feast or the carnival, contents differ significantly from educational or developmental psychology perspectives. I open up for an understanding of what play as ontology can be understood as, and thereby enable second readings. I illustrate this thought by an empirical example from a pre-school context which where created alongside with the children in the study.

The transformer is one of the most common and most important electric machines for power companies. Cost of investment and the economic worth of a transformer are counted in millions of SEK. Because of that, proper maintenance actions that may lead to longer technical life time should be the aim in all situations.The aim with the report was to perform transformer diagnosis by dissolved gas analysis on Umeå Energi AB´s power transformers and a risk assessment. The report should also contribute to longer life time for the transformers.Oil samples were taken from each transformer two times. The first sample in summer 2013 and the second in April 2014.

This report present the design and manufacturing of a wide-band driver amplifier placed in radar module for airborne applications. The major goals for the amplifier were a high efficiency and to deliver a predefined output power. To reach the second goal an additional preamplifier had to be constructed. The amplifiers were constructed in three steps: Design and Layout in the software Microwave Office, Mounting components and Verification. The driver amplifier was decided to be a push pull configuration consisting of two parallel transistors biased in class AB.

This essay is about the planning of Stockholm's border regions (areas on the outskirts of the city) during the first seven years of the 21st century. It describes how planning decisions are made in reality, in respect to a 'green' perspective. By describing what a "markanvisning" is (the right to negotiate with the city about a certain piece of land) and by discussing examples of what has happened with a hundred applications for markanvisning, this essay shows how Stockholm's border regions are planned. In the majority of cases it is the initiative of the future developers that begin the planning and construction processes. Research shows that the application to get a markanvisning in Stockholm does not follow a clear, structured system. However, the existing system in Stockholm does work and it seems like almost all the employees within the municipality, the politicians, and the future proprietors are happy with the current situation. Interviews have been held with key individuals involved in the planning process.

To get rid of our dependence on fossil fuels we need to make use of renewable energy sources like wind power to a greater extent. Even though wind power is a renewable energy source it can still cause some problems for the close environment. One of the problems is shadow flickering. When the sun is low and the wind blows in a direction so that the rotor blades are positioned at right angles to the sunbeams and ?cut? the sunbeams off.
