This thesis describes possibilities for Metso Paper to lower their costs of spray pipes for their pulp wash press TRPE, with maintained good functionality and quality.Information that can be used by competitors has been censored in this version of the essay.To find solutions, alternative suppliers have been contacted and asked to quote. There has also been a new spray pipe designed. The manufacturing costs of the new design have been calculated.The thesis also contains a concept generation of an alternative product to the spray pipes in installations where a high pressure washer is used.To be able to ask other manufacturers of spray pipes to quote, a demand specification based on the currently used spray pipe was made. This was then sent to two alternative suppliers.An investigation of earlier used spray pipes, and the currently used, shows that the nozzles are a big part of the total costs of the spray pipes. To attempt to reduce the nozzles high cost an concept generation was made to find the best solution for a new design.There was a request that it should be possible to change the internal brushes in the spray pipe without cutting and welding.

Regionalization has become a catchphrase in European countries during the last twenty years with the establishment of the European Union. An ideational development has occurred during time towards emphasing more politicially powerful regions with the idea of new regionalism. Sweden represents a deviant case study, where regions historically have been politically weak and where Sweden has been characterized as a strong unitary state. The aim of this paper is to analyze the political debate in the Swedish parliament concerning the implementation of a stronger regional level (storregioner) during 2007-2010 and to determine if the debate can be characterized as a case of depoliticalization. The theory of depoliticalization have been introduced by Richard Katz and Peter Mair to explain why political parties through external pressure from europeanisation and globalization tend to become more consensual with similar political agendas, leading to a diminished the lef-right scale.

This report contains a degree project made by the mechanical engineering students Lennart Andersson and Daniel Jansson. The project has performed in assignment by SOMAS Valves AB in Säffle. SOMAS are leading in development on control and on/off valves. To maintain this position they always want to improve their products. One way in this development is valves that are more tightened.The purpose with our project was to investigate another seat design on a HiCo (High Cobalt Alloy) seat to a SKV 150 PN 25 valve and compare this to an original HiCo seat.By modifying the seat on a ball valve we want to achieve a valve that leaks lesser then a valve whit original seat.

This study will analyze and interpret the performance art piece The Last Strawcreated by the artist group High Heel Sisters. The aim is to search for potentialfeminist strategies in their deconstructive ways of incarnating gender and bodiesusing the notion of performativity and phenomenological theories.My study shows that the diversity of this art performance creates a complex platformwere discussions about gendered corporeality and spatial power relations are beingnegotiated..

The Swedish government have a goal that wind turbines shall produce 30 TWh by the year 2020, compared to about 3,5 TWh produced in Sweden during 2010. To minimize the disturbance that wind turbines create the Swedish Environmental Protection Agency has stated a guideline value that noise from wind turbines at nearby residents shouldn?t exceed 40 dBA, at 8 m/s wind speed. With advanced calculation models, like Nord 2000, the emitted sound from future wind turbines can be calculated at an early stage to optimize the power production without exceeding the 40 dBA. When the turbines have been built there is a need to verify that they really are within the guideline.

As EU?s authority increased the number of lobbies in Brussels grew. Today there are approximately 15 000 lobbyists in Brussels. EU decisions and EU directives can have a huge impact on companies and organizations. They can however influence these decisions and directives through lobbying.

The purpose is to analyze if the students have any use of their computer education at a senior high school level or if there is a demand for them to proceed studying. Does the students background have any importance or is it their own motivation that makes the student advance to higher education.In this report we ask ourselves the question, if the students have any use of the knowledge gained at senior high school in computer studies at a higher level. Do the students have any chance for employment based on their senior high school grades in computer studies after graduation?  Do the schools that follow the senior high school guidelines within programming and databases give these students an advantage towards those that have not received the same fundamental education?The method used for the survey is a group questionnaire.  The questionnaire was distributed at one and the same time and then collected to examine the results. The survey results showed that students who seek work based only on their senior high school grades, received only a temporary position for different lengths of time.

Aim: The aim of this study was to describe nurses' experience of occupational stress and factors that contribute to occupational stress. Method: The method used was a literature review. Results: The analysis resulted in five themes which describe nurses' experiences of occupational stress and factors that contribute to occupational stress.

This bachelor thesis in mechanical engineering was performed during the spring2015 in collaboration with Composite Consulting Group in Laholm. TheComposites Consulting Group works mainly with design and details of differentcomposite projects, their main area is FE-calculations, 3D-modelling andmechanical tests with composite materials.The aim of this bachelor thesis was to simplify the calculation process of solidmechanics for sandwich panels by simulation with computer software. The goalwas to decrease the time for the design and calculation process of the constructionand the cost of the practical tests. Our task was to build a static three dimensionalmodel with the computer software Abaqus, where the result should correspondwith the practical pressure tests in laboratory.The project started with collection of material data from Composites ConsultingGroup and by learning the software Abaqus, simultaneously a specification wasdeveloped in corporation with the company. Later on, a static wheel pressuremodel in the software Abaqus was produced which simulated the behavior of thesandwich panel during static wheel-pressure by a pallet truck.

Our society has become increasingly digitized, and all around us information flows constantly. Knowledge about valuing different sources of information, and not least the information itself, are becoming increasingly important. Media and information have come to play a big role in our society, and knowledge of media and information literacy becomes important to learn in school. High school students are at the beginning of their adult lives as educated citizens.In this study, we measured high school students experience of media and information literacy, during their three years in high school. Students answered a questionnaire, with questions based upon theoretical concepts in media and information literacy.

In this study, the sea trout (Salmo trutta) spawning migration was studied in the river Själsöån, Gotland, to assess the main external factors determining upstream migration and seasonal changes in fish parameters. Additionally population trends were studied by examination of old data. The most important external factors for upstream migration were the air pressure, air temperature and wind direction. No significant difference was found between when males and females migrated upstream. Larger females in better condition started migration earlier than the smaller females in poorer condition.

Water hardness indicates the concentration of calcium and magnesium ions in water. Water with high concentrations of these ions is described as hard water and water with low concentrations is described as soft water. Water that is too hard or too soft can lead to technical and economical problems. In collaboration with Midvatten AB, groundwater hardness in the Badelunda esker between Leksand and Avesta has been mapped, and an attempt has been made to explain the variations. For this purpose, different GIS programs, such as ArcView, ArcInfo, IDIRISI, and one geochemical modelling program, PHREEQC, has been used.
