AbstractThe future of ethanol is depending on good solutions for the production. ENA energy power plant produces electrical power and district heating by heating biofuel. By building an integrated bioenergy plant surplus steam could be used to produce ethanol as fuel to vehicle.This would mean that ethanol is produced renewable energy and the energy for the process derives from the surplus of power.  ENA energy, MDH (the University of Mälardalen) and the energy authority has initiated a research project were different bioenergy combinations integrate with existing power plant.  As a part of the project which size an integrated factory should be to gain the best efficiency for the plant was investigated. Consideration will be taken to the cost of the production in order to be competitive to the price of imported ethanol.  Etanolens framtid vilar på bra lösningar för framställning.  I ENA energi kraftverk i Enköping produceras el och fjärrvärme genom eldning av biobränsle.  Genom att bygga ett integrerat bioenergikraftverk där skulle man kunna använda överskottsånga till att framställa etanol som fordonsbränsle.

As a consequence of increasing wind power installations in the Nordic grid the last years, the need for regulating power has become larger. In the Nordic grid, regulating power is mainly provided by hydro power. One part of the regulating power is called frequency control, which ensures that the grid frequency is stable and close to 50 Hz.However, setting the turbine into frequency controlled operation may cause stress and wear of the components in the mechanical control system. Frequency controlling implies large and frequent servo forces and longer travelling distance of the sliding bearings in the Kaplan turbine.Based on one selected Kaplan turbine, Selsfors G1, measurements and MATLAB calculations have been performed in order to determine forces and movements of the linkage system. With these forces and movements as input, stresses and fatigue have been determined as well as sliding distances, bearing pressures and wear of bearings during a typical lifetime of 40 years.The results indicate that no severe wear exists on the bearings during 40 years of service.

AbstractEssay in political Science (c-level) by Karin Forsling, Spring 2007A school for the best interest of the child? - The Swedish School System according to the UN Convention on the Rights of the Child.Supervisor: Stig MontinThe purpose of this essay is to investigate how the Swedish governments work with the im-plementation of this convention and what progress has been made. The inquiry of this study is to describe how the changing in the Swedish School System correspond to the national strat-egy for implementation of UN Convention on the Rights of the Child in Sweden and how the political protagonists.I have read some of the most relevant documents from the authorities and organisations work-ing with children?s rights in Sweden and papers and communications from the political pro-tagonists.Since UN Convention on the Rights of the Child was ratified by Sweden in 1990 the work for implementation has been quite successful but there are still lots to do. There are still some problems in School such as bullying, insulting, insecurity and lack of peaceful and harmoni-ous school environment.

The increasing significance of social economy as a concept is linked to general global processes such as the crisis of the welfare state, neoliberal globalization, anti-bureaucracy tendencies and decentralization, but also to a growing political interest in human rights and social development. In Sweden the idea of the social economy generates wide support within civil society as well as within the government and across party political boundaries. Furthermore, what is problematic in this context is the fact that the discussions on the subject tend to be relatively uncritical and often it seems as if though the expansion itself is the main objective. The emphasis on cooperation and the third sector in terms of welfare production implies a set of risks in relation to state responsibility, democracy and the autonomy of civil society. This paper aims to explore those risks and how they can be dealt with within the Swedish context..

Kärnkraften har så länge den funnits varit en omdebatterad energikälla. Syftet med denna uppsats är att utreda och få en bild av hur och på vilket sätt natursynen hänger ihop med åsikter om kärnkraft. Jag har redogjort för vad energi är, kärnkraftens historia i Sverige och som energikälla samt beskrivit för- och nackdelarna med kärnkraften. För att kunna ge en bild av kärnkraft och natursyn har jag genomfört kvalitativa intervjuer med personer som på olika sätt är insatta i problematiken kring kärnkraften. Min undersökning visar bland annat att natursyn är ett komplext och stort begrepp som vi bör vara medvetna om hur det fungerar i arbetet för att förbättra miljön..

AbstractTitle: 2008- the year of the mobile-TV-markets expansion? (2008- ett år för mobil-tv-marknadens utbredning? Drivkrafter hinder och aktörer).Number of pages: 50Author: Hilda EngstrandTutor: Lowe HedmanCourse: Media and Communication Studies CPeriod: Fall Semester 2007University: Division of Media and Communication, Department of Information Science, Uppsala University.Purpose/Aim: The aim of this research paper is to identify the main operators on the mobile-tv-market and to map out the main forces behind its growth. What are the driving forces that creates a new disribution-market? Also to study how political media-regulation effect and urge the mobile-tv- market.Material/Method: Interviews with people from the mobile-tv-market. To read public-documents, press releases and reports from the government, media-companies and organisations has also been a method used to gain information.Main results: That the mobile-tv-markets growth is a result of several driving forces.

At the Congress of the Swedish Trade Union Confederation (LO) in 1991 a decision was made to reform LOs politics of gender. In the new resolution class and gender were established as equal causes of oppression. This was a giant leap from LOs traditional politics, where the dimension of class had always been considered more important than gender. The present thesis discusses how gender was constructed in LOs discourse after 1990 by analysing their official publications about gender politics called Klass och kön. The key terms in the analysis are continuity and change.

Written declarations in the European Parliament have not been given muchattention in the field of political science. The scope of this Master's thesis is toexamine whether symbolic politics are present in written declarations and howthis may show. In this study, the aspects of symbolic politics of writtendeclarations of the sixth parliamentary term are examined using a taxonomy foridentifying symbolic politics developed by Peter Santesson-Wilson. Thetaxonomy is applied on 15 written declarations, all adopted by the EuropeanParliament, dealing with a variety of EU-related issues, ranging from July 2004 toJuly 2008.The main findings of the study show that symbolic politics is a presentphenomenon in nearly all written declarations (13 out of 15 cases) subject to thisstudy.In the final chapter of this study inter alia symbolic politics as a deliberateaction is discussed in the view of written declarations. Irrespective of this, onecould say that symbolic politics are institutionalised in the European Parliament,at least when it comes to written declarations..

On December 20, 2001, the Swedish citizen Mehdi Ghezali was captured on the border between Afghanistan and Pakistan. Ghezali spent the following 930 days in U.S. captivity, without being charged with any crime. My aim in this essay is to analyze how Ghezali was portrayed in three Swedish newspapers under and after his captivity, two nationwide and one local newspaper based in Ghezali's hometown. My purpose is to see whether Ghezali's identity is constructed differently in the three newspapers, as regards The Other, Stereotypization, etc.

This essay is aimed at exploring how governments inclination to adhere to international human rights law develops in the wake of interstate conflicts. It examines how human rights in Eritrea and Ethiopia has developed after the war in 1998-2000 by examining the historical background to the war, and reviewing country reports from United States State Department and Amnesty International between 2001-2005.The result of the paper shows that Eritrea's adherence to human rights suffered setbacks, and that some of these happened due to the aftermath of the war. Ethiopia also had some lesser setback primarily due to internal turmoil. The essay concludes that states adherence to human rights in postconflict situations depend on if the war severely weakened the state, in which case the state becomes more repressive in order to cling to power..

In this thesis a method for evaluating investments in small scale hydro power is presented. An analysis of the future position that small scale hydro production will have on the Nordic electricity market is also carried out. This is done by an inventory of technology and economic and environmental aspects. The inventory is also a guide as to how the project should be implemented.Hydrolyzer is the name of the Excel tool developed to evaluate investments. The tool requests input data from the user and then evaluates the investment and generates a sensitivity analysis.

The chosen task in this thesis is to compare two projects of importance on the impact on the approach to graffiti in Norrköping and Göteborg. My main source for empirical findings was interviews. I have examined the Norrköping project Canslit including legal graffiti walls and a graffiti school and the political process around it. This was compared to the Göteborg project kulturprojekt Röda Sten, which is a cultural center that happens to be covered in illegal graffiti. The conclusion was that due to the very detailed plans and well-functioning communications between actors in the Norrköping project, this has resulted in a creative, tolerant approach to graffiti still with low rate of illegal graffiti.

Within the political science research it is common to examine the effects on the national parliaments caused by European integration. In this Bachelor Thesis the aim is instead to show what involvement of the national parliaments in the European Union implicates to the European integration process.The object of examination is the introduction of the parliaments as supervisors of draft legislative acts, this is also known as ?the Early Warning Mechanism?, through the ratification of the Lisbon Treaty. An analysis of answers from the national parliaments in the tests of three pilot cases, conducted by the COSAC, is made with help of Institutional theory and an Europeanization perspective.The main findings show that the mechanism of early warning probably will not become an obstacle for continued European integration, but it could slow down the process in some areas. Most probably though is that the mechanism forces the national parliaments to adapt and to be better equipped to react at events taking place at the European level.

The goal for this master thesis project has been to investigate the power quality in adistribution grid, which has a high fraction of dispersed power production due towindmills. The study has been done on a grid in Laholm South of Halmstad, whereapproximately 45 windmills are connected to the distribution grid owned by SHKEnergi. The investigation has been focused on to two radialy fed 20 kV lines, wheretwelve windmills are connected.Voltage variations have been studied by creating a model of the grid in the simulationprogram SIMPOW. The largest deviation that has been found in any point of the gridis ±1.9 % of the nominal voltage. This deviation is a result of varying powergeneration from the windmills and the voltage regulation at the connection point ofthe line.
