This thesis was performed at Vendig AB which is a company that develops and sells products such as belt scrapers for conveyor. The thesis is divided into two parts, one part where it´s investigated which tension force is required to tighten Vendig AB´s scraper Hampus against the belt in a correct way. The second part is called mechanical design and here a new and more compact tension device is developed.Field studies has been conducted at a couple of Vendig AB´s costumers to get a knowledge base about how Vendig AB´s products are used, how they function and the environment they operate in. During one of the field studies the force between the scraper and the belt was measured. The result from the measurements, together with a report from LKAB [1], were evaluated and summarized in a table.

The aim of the study was to examine if and how the social service and the social welfare secretary provides against threat and violence in the encounter with clients. The study is qualitative and carried out with six semi-structured interviews with social welfare secretaries and participation observations at the social welfare offices in three municipalities. The theoretical starting points used were symbolic interactionism and strange loops. The result shows that social service and social welfare secretaries both use measures to prevent threat and violence to occur. The precautionary measures mainly used by social services are ; looked doors, alarm device, loose objects removes and interview rooms are furnish in purpose for the social welfare secretary to flee the room at urgent need.

Nation building is vital in post-war states to bring the people that have been at war together. To restore peace in a state, many different actors need to work together to bring stability, safety, and advancement to a new nation. There are several methods of nation building, and this thesis evolves around three of them. This is a qualitative study where three theories on nation building are used to analyze the development of nation building, and the obstacles Bosnia and Herzegovina still has to reach a national identity. Several studies are used in this thesis to show how the development has evolved in Bosnia and Herzegovina.

A product and design development of a household device which shall dry food waste has beencarried out in collaboration with Smedlund Miljösystem AB.This project has been implemented through several brainstorms and a questionnaire study.A great insight of how it is to work in a project in real work life has this project been givenme. This is a slightly less straight road to a conclusion than in the academic world that I amused to..

 Syfte: Att undersöka huruvida patienterna upplever det postoperativa förloppet avseende smärta i hals, heshet, smärta vid sväljning samt generellt obehag beroende på om endotrakealtub (ETT) eller i-gel supraglottic airway device (SAD) använts i samband med generell anestesi vid elektiv kirurgi.Metod: I denna kvantitativa tvärsnittsstudie samlades informationen in på formulär. Parametrarna skattades av patienterna med hjälp av visuell analog skala (VAS). 60 patienter tillfrågades konsekutivt till studien och 13 föll bort vilket resulterade i 47 patienter som fullföljde studien.Resultat: Gällande graden av smärta i hals, heshet, sväljsvårigheter och allmänt obehag postoperativt så skattade sammanlagt sju deltagare i grupperna med ETT och i-gel ett VAS värde över 3. Patienter som haft ETT upplevde signifikant mer heshet, och sväljsvårigheter än patienter som haft i-gel.Slutsats: Denna studie visar att patienter som får ETT eller i-gel skattar sina besvär avseende smärta i hals, heshet, sväljsvårigheter och allmänt obehag i en låg frekvens. Dessutom påvisas att majoriteten av de som skattar besvär gör detta i de lägre segmenten av VAS skalan..

While designing an intranet for people with mobile work there are things you have to consider. This thesis is aim to bring understanding to the difficulties involved in these kinds of situations. Our focus is to develop ideas that motivate the assistants to use the intranet. We have looked into the profession of personal assistants and wish to highlight their problems to access the intranet. And we will as well demonstrate their needs for communication.

Is it possible to convey spirituality through art and material culture? Is it possible to renew art within the traditional church so that it appeals and is understandable for the modern man? These are the fundamental questions of my master´s work, which has it´s starting point in a public commission for an artistic contribution to the new Pentecostal church in Kalmar. The work also addresses the question whether there is a need for symbolism, art and sacred objects also within the Pentecostal movement, a traditionally strong image hosting environment. If so, how is it possible to bring this in to the church without completely breaking with the tradition and ideology of the movement? I want to communicate the Christian message in a renewed way, and in this particular project also highlight the importance of using images also within the Pentecostal movement.

The mouse (Mus musculus) is the most commonly used mammal in biomedical research and can easily be restrained by both hand and by a device. Restraining animals causes stress that not only decreases the animal?s wellbeing, but may also influence the research results. The first aim of this study was to train mice to voluntarily stand still using positive reinforcement training. Another benefit of teaching a mouse to stand still is that you can avoid anaesthesia for some procedures.

Most of the portable electronic devices use a battery as a primary power source. Nowadays, when the applications are becoming smaller and smaller and more power efficient, the designer needs to concentrate more on reducing power consumption, using secondary power sources and introducing power storage devices. Multiple power source availability and a power storage device on the board will make the applications much more useful and efficient in everyday use. This thesis proposes a power supply unit (PSU) for wireless sensor platforms which is capable of supplying a sensor node with energy from multiple sources, as well as status information from the PSU. Present power storage devices, like electric double-layer capacitors (EDLCs) and batteries, have become more and more common as their characteristics have developed.

This thesis is a process oriented case-study. The studied case is a interactiondesignassignment of a databasevisualisation and the process. The goalis to do this according to the ways of a screenwriter.When the computers spread from the military and university's into homes all around the world the computers and the programs had to becomeeasier for the users to understand and use. User interfacedesign became more and more important and companies like Apple put a lot of resources intothe designprocess. This quite new and evolving area of research, interactiondesign, has been forced to search for methods in other areas like lm, gamedesign, psychology and behavioural science.

We are getting smarter. Our knowledge of the world around us is increasing rapidly and our population spend a big portion of their time in school studying it. But art and craft are moving out to give room for more theoretical subjects. Today many of us can not even fix a torn shirt without help. We buy new ones, they are cheap enough.

This thesis is the result of the investigation and solution of a mechanicalproblem regarding flywheel malfunctions. A flywheel is, in short, a devicethat relies on a rotating object?s moment of inertia to store energy overshort time spans. This project is part of the development of a fourthflywheel prototype at the division for electricity at Uppsala university,which uses magnetic levitation to keep a hollow cylinder rotating at veryhigh speeds inside a vacuum chamber. Should the magnets fail however, orsome other error occur that leads to an uncontrolled state of rotation, thecylinder needs to be stabilized mechanically by a device usually referredto as ?back-up bearing?.
