Konstruktion av anordning för att undersöka förslitning av syrebärarpartiklar för kemcyklisk förbränning
The purpose of this work is to design and construct a device able to measure the mechanical attrition of oxygen carrier particles. Those particles are used in chemical looping combustion and in the present situation there is a lack of knowledge in how the attrition process work and in which extension. To find already tested solutions trying to answering this problem a literature study wascarried out and the best solution found was the so called Grace-Davison Jet-Cup method. This method is supposed to emulate the attrition caused by a cyclone separator and its advantages are that it is possible to use small test amounts, 5-10 g, and a thirty minutes long test will be enough to acquire useable results. An device was designed based on the Jet-Cup method with some slight modifications.
Nyttoforskning. En studie av den svenska forskningsfinansieringen för humaniora och samhällvetenskap med Riksbankens Jubileumsfond som exempel.
In this paper I argue that the development of innovation ideas within the financial system of scientific research might have a counterpart within the financial system of the social sciences and the arts. The ideas of innovation share a common way to evaluate science in terms of how well it can contribute to economic growth. In the past two decades a similar development can be observed within Riksbankens Jubileumsfond (RJ), one of the largest external financiers of the social sciences and the arts in Sweden. The idea of evaluating research used by the innovation ideas has grown popular within RJ, only it seems they evaluate research in terms of how well it fits into an international research community rather than how much it can contribute to economic growth as is the case within the innovation ideas. By examining the different ways of financing research that RJ has used during the last 2 decades, this paper aims to introduce a new perspective in which it is possible to understand the development within this type research funding as a part of a bigger system of development..
Bibliotek, Finkultur och TV-spel : En diskursanalys av debatten kring TV-spel och bibliotek
This bachelor´s thesis analyzes the debate in a number of Swedish media regarding the introduction of video games as a new medium in the public libraries. The theory and method used is discourse analysis. Three questions were asked: how the introduction of video games as a new media in libraries is discussed, how is it motivated and in what way the authors of the articles analyzed are speaking about new media and the mission of the library. The selected articles were divided into four themes and the analysis resulted in the identification of two main discourses, one which is positive to the introduction and integration of new media in the libraries? collections, and one which has a more negative approach and uses quality and culture as an argument. The conclusion is that video games are a medium so widely used that librarians have to decide whether or not they want to include it in the libraries? collections, and by deciding this they reveal their attitude towards the mission and purpose of the public library..
Vägval: kortast, snabbasteller hälsosammast : En försöksmodell i GIS för ruttoptimering och beräknad inhalation av luftföroreningar för cykelrutter
Cycling is one of the most sustainable transport modes available and it is widely promoted inmany urban areas. The health benefits from cycling has shown to be substantial, includingdecreased risks of diseases related to overweight and enhancing brain capacity. However, inurban areas cyclists can temporaly be exposed to high levels of air pollution, resulting inhealth risks as opposed to health benefits.The objective of this thesis is to develop a rasterbased test model in GIS that estimates theinhaled dose of air pollution for cyclists based on relative particle concentration in differenttransportation micro-environments. The method used is a least-cost path approach,calculating three different routes; shortest, fastest and least dose for four different trips withinSödermalm, Stockholm.The results show that the inhaled particle dose can be greatly reduced, 39% - 58% for three ofthe routes, by choosing the least dose route. One of the most interesting findings is thesubstantial increase of dose when high levels of particles are combined with uphill cycling.The conclusion for the thesis is that a raster-GIS model can be very useful for estimating doseof different air pollution particles and chemicals along cycling routes.
Digitala bibliotek i kulturpolitiken Om idéer och legitimitet.
The aim of this Masters thesis is to examine ideas used to legitimate Swedish digital libraries, with a focus on the cultural heritage, their relation to cultural policy and an eventual crisis within the latter. Which ideas are linked to digitalisation? How do the arguments for creating digital libraries differ between central actors? How do the digital libraries relate to cultural policy and an eventual legitimacy crisis? These are the questions this thesis seeks to answer. The theoretical starting-point consists of a legitimacy discussion and its connection to Swedish cultural policy. The method used is idea analysis.
Kartläggning av spånprodukter vid Sävar såg
A change towards using more biofuels than fossil fuels is taking place in Sweden, and in many other parts of the world. This makes the use of fuel pellets increasingly popular, causing a greater demand for sawmill sawdust products. There is a trend towards the use of multiple types of shredders, instead of a single type in each sawmill. The purpose of the study was to characterize the different flows of saw particles that can be found at Sävar såg when cutting thick or thin wood with different cutting techniques. The saw particles size, shape, moisture content and heat value were analysed by the cutting stations: first cutting fast and slow, second cutting fast and slow, grading fast and slow and planning.
Sju husmödrar berättar : en etnologisk studie om husmödrar under mitten av 1900-talet
This thesis is about how ideology affects the way leadership literature measures good and bad leadership qualities. The paper argues that ideological influences in leadership literature, from a teacher perspective, complicate the understanding of leadership in its practice and theory. The methodological tool used in this thesis is an idea- and ideology analysis approach applied on leadership literature that is used in teacher education. A theoretical discussion about the definition of leadership and its possible ideological connotations sets a frame for measuring ideological influences in the texts. The analysis from the textbooks showed clear signs of ideological influences when talking about leadership.
Introduktion av mat till barn som ammas : Vad BVC ger för information och hur föräldrar gör
In 2001 the World Health Organization (WHO) issued a revised global recommendation for exclusive breastfeeding for a child ´s first six months. The aim of this study was to investigate what information parents receiving from the Child Health Care about introduction of solids to breastfed infants and if they follow the recommendation. A further aim is to document reasons for introduction of solids at the selected time and describe what food parents start with.The method has a descriptive and a qualitative design. Users of several Swedish parenting websites were asked to participate in the study. A total of 27 users completed the anonymous open-ended questions posted on the websites.
Om Gud vill får jag stanna ? en studie av hur nyanlända asylsökande upplever det mottagande de fått i Sverige.
The purpose of this essay has been to investigate how newly arrived asylum seekers experience their first month in Sweden. The focus has been on the introduction week that is given within the first month of their arrival, although the study aims to treat the reception that is given in general. This is important because the refugees are in a sensitive state, leaving their country for different reasons, and coming to a new place wich they know nothing or little about. The questions at issue has been the following; * What are the refugees´ views of the information and the treatment they´ve been given during their first month in Sweden? * Which are the possible reasons for the refugees experiencing the reception the way they do? The methods I´ve used have been observation studies during the introduction week, plus interviews with participants of this introduction.
Exponera mera : ett arbete om skyltning på bibliotek
This Master s thesis deals with the display of library media, whether it is conceivable and desirable to draw inspiration from the retail business when displaying articles. The questions asked are: are there, in the retail sector, well established display ideas and - if so - what do they look like? Are the similarities in conditions, between the branches, sufficient? In conveying the ideas to libraries, are the potential differences not obstructive? Is there, among librarians, a positive attitude towards further development of library display techniques? The results were achieved by interviewing shop window dressers and librarians. In addition, a survey was sent to the library managers of 65 public libraries in southern Sweden. The results show that there are established ideas and methods of displaying materials, and that the ideas are manifested in frequently used techniques.
Idéer om folkbiblioteket ? en idéanalys av ett urval kommunala biblioteksplaner
The aim of this master?s thesis is to examine which ideas about the public library that appear in a selection of municipal library plans and to examine if these ideas are unanimous. The comprehensive questions are: Which ideas about the public library appear in each municipal library plan? How do the ideas agree in the different municipal library plans? The sub questions are: Which judgements of reality appear in the different library plans concerning each municipality and its library needs? How do the municipalities define the concept of development and future demands in the municipality on the basis of the judgements of reality? Which recommendations do the judgements of reality give and how is the plan of action that is established in each library plan justified? Which fundamental views of reality, i. e.

Konstruktion rörklammer
This report describes the development process of a pipe clamp used on exhaust system for cars. It is made based on the manufacturers desire to improve and make the clamp easier to manufacture and to reduce its price to their customers. This should be done either by manufacturing the clamp in one piece without an expensive and work intensive welding process, or by generating ideas of how to develop a brand new type of clamp. Investigating the market for similar products was done to eliminate intrusion of other manufacturers? patents but also to generate ideas.
