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.

Emma Nordin: Emilie Du Châtelets analys av lycka: Upplösning av polemiken mellan illusion och förnuft. Uppsala universitet: inst. för idé- och lärdomshistoria, C-uppsats, höstterminen, 2012. The 18th century is a time period known for its battle with superstition, illusion and falseness. With the Torch of Reason the philosophers of the time were set on vanquishing everything untrue and lead mankind into what they themselves called the Enlightenment. Happiness had moved from Heaven to Earth in science, truth and pleasure.

Few studies enlighten the problem associated with the dialectical relationship between adults and adolescents and how that affects the construction of identity for adolescent?s, in relation to two areas that are closely bordering to each other but differs socioeconomically whereas one area is much weaker on resources than the other. These two areas is Högberget and Haganäs, which are situated in a larger city in Sweden.For us to be able to enlighten this problem we have chosen to use an inductive research approach so that we can explain how adolescents construct their identity and how the organized spare time, in addition with the influence of adults, impacts on adolescents construction of their identity.Therefore we have used interviews as method, both group and individual, so it can regulate which theories that influence our study. The two theories that wires through the entire study are firstly Peter L. Bergman and Thomas Luckmanns theory on social construction where the idea is that the human being is an active social being that constructs its own reality.

The purpose of this study is to examine how school meals are organized in a selection of Stockholm's secondary schools and to examine the relationship between school meals and the different parameters that indicate each school's symbolic capital and educational capital. By looking at the statistics from each school on the basis of the final grade average, percentage of pupils with foreign background and gender, I examine whether it is possible to see a relationship between how schools organize meals and which pupils attend the school.  In my study, I systematically went through each school's website and tried to identify how school meals at each school are organized. To increase the validity of the study, I have also conducted a questionnaire survey by mail addressed to school principals.   In order to analyse and understand my results and put them in relation to my current knowledge about the schools in my sample, I am using Bourdieu's theoretical tools that a given aid, both in methodological and analytical purpose. Based on Bourdieu's theories of symbolic capital, cultural capital and educational capital, I can understand and analyse school meals are organized and focused as part of schools' symbolic assets in competition with other schools.   The first part of the study shows that there are four different organizational models for school meals, fully equipped kitchen and canteen, heating kitchen and canteen, school meals in restaurants and school meal card.    In the second part, I have examined the relationship between the type of organization for school meals used and the symbolic resources available at the school. I can conclude from the results that it is difficult to find a correlation between the symbolic resources and the different categories. But even though it is not possible to see all the schools' symbolic assets equally clear, there are still some very telling examples. In many ways, these examples can be seen as polar opposites to each other based on Mikael Palme?s concepts ?goal rational? and ?education oriented? schools..

The purpose of this study is to interogate the tension-laden relationsship between men (of the dominant classes and ethnicities) and feminism. Closely linked to this lies the question of how valid and relevant official Swedish goals of gender equality can be to the Centres for Women´s Studies and Gender Research in Sweden.The essay is mainly an in-depth qualitative study concerned about questions such as; how does feminist researcher in Sweden perceive the question of men in/doing feminism and what are the implications of these perceptions for the Swedish goals of gender equality? Thus, in this study I´ve interviewed six feminist researchers, five women and one male, about their view of men doing/in/and feminism and about the adequacy of equality goals to the Centres for Women´s Studies and Gender Research in Sweden.The main questions I posed in this essay was prompted by the Swedish political scientist Bo Rothstein accusation of two feminist Swedish researchers, Yvonne Hirdman and Maud Eduards, of deliberately harassing men interested in feminist theory and striving to create women-only spaces at the different Centres for Women´s Studies and Gender Research around Sweden. This would according to Rothstein violate the Swedish goals of gender equality where equal representation is essential.However, the empirical material shows a benign attitude towards men doing feminism and the interviewed all stressed the importance of diversity among feminist scholars and students.As for the Swedish goals of gender equality, the interviewed expressed diverse and contradicatatory answers concerning how valid those goals should be to the Centres for Women´s Studies and Gender Research in Sweden.Contrasting the empirical material, my own argument in this essay circles around a critique of the validity of the Swedish goals of gender equality to the Centres for Women´s Studies and Gender Research in Sweden. Seeing men as a group with groupbased experiences, perspectives and interest puts the female dominance at the Centres for Women´s Studies and Gender Research in Sweden in another light, making the absence of men not a question of harassment but a question of male privilege to stay ignorant and indifferent of gender relations..

The vision of this thesis was to create a concept that can be used as a base for amachine construction. The purpose of this project was to use different methods todevelop a concept that on the best way meets the sat up requirements. This projecthas been divided into three stages/parts; principle, primary and the final solutionstage.This thesis has been conducted in collaboration with Västkustägg AB. It is aconstruction project designed to construct a machine that will automatically putlabels on the egg packages. Västkust AB wanted to automate this process.

This essay provides an attempt to reflect the notions of violence, right or law and fate in Benjamin?s Zur Kritik der Gewalt, in order to clarify his very dense historical-philosophical reflection on the constitutive relation between violence and law. In contrast to what is most often the case, this essay will not address the notion of divine violence in a direct sense, but mainly focus on Benjamin?s discussion on right and law. The complex of his historical reflection, his attempt to articulate what he calls the ?historical function? not only of violence, but also of law, is crucially related to the notion of fate.

Over the years, what people have considered as the center of Stockholm City has gone from the medieval Stortorget in Old Town to the contemporary Sergels Torg. But more recently it has become unclear how the area really works. It is difficult to say where the actual central part of Stockholm lies, because while the Central Station is where the majority of people arrive into town, it is not necessarily close to Sergelstorg (considered the center of town) or other attractive commercial areas. There's also another issue with where the center of Stockholm is located. The railways and roads running along Klarabergs Viaduct acts as a divide between the areas of Kungsholmen and Norrmalm; these rails, roads and water separate the two areas from each other. In response to this problem of area division, a plan is being made to construct a new district near the center to mend the gap between the districts. The idea is that the center of Stockholm city will become more lively and attractive. The plan includes building new housing, commercial areas and a larger terrace called Mälarterrassen. In addition, improved mobility within the area is being planned by having better public transportation lines like City banan and tram named Spårväg City construction, as well as more pedestrian areas shall make the area become a district to thrive in.How the area will actually operate in the future is still unclear and many questions still exist about how the area will be able to compete and, above all, integrate with the other districts. The parts considered to be most important for the area is the scale of residential property and an attractive area that keeps people in the area and to encourages them to pass through the area. Perhaps the best solution would be to have something special planned in this area that can attract people in the community ? a city park, for example?.

This essay concerns the notion of how immigration politics, defined as a political discursive structure that explains and justifies how and why the movement of people into a state's territory is restricted and controlled, has come to present its purpose not as solidarity with the 'immigrants' wanting to enter the state but as a protective measure for the state's citizens. By using discourse theory combined with theories from the International Relations field I attempt to explain why and how such a discourse positions 'immigrants' as a threat to the state.First, I concentrate on why an immigration politics discourse would position 'immigrants' as a threat. I argue that in order for people to construct their identity, the 'outside' what they "are not" has to be repressed. In the same way, the state has to dislocate the "outside" and create threats to uphold its supremacy. These boundaries are set to create a feeling of predictability and security, and ultimately they are a way of making peoples' "world" coherent.

Recent studies made by Margaritis and Psillaki,have shown that a lower debt ratio and higher efficiency are correlated in their studies performed oncompanies in New Zeeland. Other researchers have been able to show a connection between other industries than the one used in our studies,among these are Titman and Wessler. These studies have been done with a great selection of companies in different industries and time periods. However most of these researchers have used traditional ratios and variables.This study aims to find and analyze connections between returns and lower debt ratios in real estate companies listed on the Stockholm stock exchange. Instead of the traditional debt-equity ratio we will construct our own taking long term debts and property assets.

This essay is a discourse analysis of the integration politics of the different parties in the Swedish parliament and the non-parliamentary party ?the Swedish Democrats?, as it is presented on their respective web pages. The overall purpose is to problematize and shed a light on how the current discourse(s) about integration are constituted. Also of interest is how these construct our knowledge and experience of the phenomena. We furthermore want to illustrate the social consequences of such discourses on the construction and organization of identities and groups, and, as a result, the courses of action that becomes available.

The rates for teenage conception and motherhood in the UK are according to recent research, the highest in Wester Europe. The ongoing debate concerning these teenage pregnancies and teenage motherhood has therefore become political in a wide range. The government?s goal is to reduce the number of teenage pregnancies until the end of 2010 to prevent social exclusion among vulnerable young women. However, there is controversy in other research that describes teenage pregnancies more likely to be a result of social exclusion than its cause.The purpose of this study is to examine how young mothers in a borough of London, from their own point of view, experience their situation, their difficulties and possibilities in present and in future.

The trend of social media is a global hit and now both individuals, businesses, celebrities and politicianshave their own social media pages, which means that the visibility increases and focus lies on what'swritten and published by the person. Mediated communication are everywhere around us and affects theway we communicate with each other and also the way we look at ourselves and most importantly how weportray ourselves. The individual's perspective has become a relevant issue with the rapid moderndevelopment. One's cultural identity can be seen as a life-long project.The purpose of this paper is to do an in-depth text analysis to examine how Swedish politicians constituteand construct identities, with a focus on "the self" and the "mediatization self" on the micro-blog Twitter.The theoretical ground for this study is from a discourse analysis point of view that focus on ?the self? andthe ?meditization self?.

Abstract  Title: Från neutralitet till öppenhet? ? En studie av säkerhetspolitikens utveckling i Sverige efter kalla krigets slutAuthor: Jens KindhSupervisor: Patric LindgrenLinnaeus UniversityDepartment of Political ScienceSpring term 2012 When the Cold War ended, a new security situation was unfolded in Sweden. The purpose of this thesis is to describe and compare how the Swedish security policy is organized and how it has changed since the Cold War ended. To do that, I?m going to try answer the following questions:How is the Swedish security policy organized?What defence resolutions have affected the Swedish security policy after the Cold War ended?How has different political actions made its impact on the Swedish security policy after the Cold War ended?My theory is to try explain how the Swedish security policy has changed after the Cold War through a realism security perspective called traditional security, which refers to a realistic construct of the states security policy.

This case study examines how a group of upper secondary school students in a multiethnical suburb of Stockholm reason about the theory of evolution. The theoretical background of the thesis is postcolonial and the questions raised were how spread the creationist thoughts are in the group; in what way the backgrounds of the students are relevant to their thoughts; how the students construct the notion of the theory of evolution; how they position themselves and others in relation to the discourse of the theory of evolution; if there are any differences between students at the collage program of natural science and the collage program of social science, and in that case, what differences; and who or what inspires the young in their thoughts about the theory of evolution. To answer these questions both a survey poll and interviews were used. The result of the case study showed that a majority of the students at the investigated school has creationist ideas and that the students profiled on social science have creationist ideas in a wider extent. Another result is that the religious background seems to be relevant to develop creationist thoughts, while the variables gender, home district and educational level did not differ the creationist group from the whole group.
