During the 19-century a global warming has been observed, which includes increases in global air and ocean temperatures, widespread melting of ice and snow, and rising global sea level. There is a clear connection between emissions of greenhouse gases caused by the human and the increase in temperature. Climatic changes caused by global warming can be stopped trough decreased emission of fossil fuels, for example by an increased use of biogas. Biogas is a renewable energy source which is produced through anaerobic (oxygen free) digestion of organic material. The gas is a mixture of methane (CH4) and carbon dioxide (CO2) and can be among others used as fuel in vehicles.

The increase in sales of the so called smart phones has meant that there has also been a requirement to determine new applications for which they are suitable. One of the largest platforms for smart phones is Android and the task of this thesis is to develop an application for a company that wishes to create interactive radio for the Internet. In addition to ordinary radio features, the company would like the application to be able to present images and a small web page called Canvas. The overall aim ,of this thesis, is to build a fully functional media player that is compatible with the majority of the commonly used Android based mobile units. To fulfill the overall aim, nine explicit goals were targeted.

This paper studies the fragmentation and reuse of early christian monuments ("eskilstunakistor") in churches in Östergötland during the medieval period. This is found to have been done in two stages. The first stage shows a collectivization of society. Within religion the change from ancestoral cult towards the saints' cult is important as the fragments are reused like relics. During the second stage the collectivization has been fulfilled, and the reuse is instead part of the christian churches' strategy for incorporating old powerful symbols from the landscape into their own church building..

Swedish libraries are currently discussing andimplementing the classification system Dewey (DDC).Most libraries in Sweden have used the Swedishclassification system SAB until recently. In 2008 TheRoyal Library of Sweden (KB) decided to switch fromSAB to DDC. Many academic libraries chose to followKB?s example and by January 2011 a switch was made atKB and at many academic libraries.The aim of this master thesis is to examine and analysethe library sector?s discussion that occurred before andduring the Swedish switch from SAB to DDC. The mainquestion asked is; What is being discussed about Dewey2010-2011 and in what manner? To organize and anlysethis discussion discourse analysis is used.

Title: I saw it on Facebook ? Youth presentation of self on FacebookAuthors: Nicole Dreher & Anders SkoglundPresented: 01.06.2010Purpose: The purpose of this thesis was to examine how the, in the study, participating youths make their presentation of self on their Facebook profiles.Methodology: The method used in the thesis was a social semiotic analysis focusing on the social semiotic concepts: semiotic resource, semiotic potential, affordance, denotation and connotation. A social semiotic analysis of composition was also used with the purpose to gain a deeper knowledge of the social semiotic affordances of Facebook?s composition.Theoretical perspectives: The theoretical base of this thesis consists mainly of Erving Goffman?s theory on presentation of self in everyday life as well as relevant theories to youth culture in sociology and identity in social psychology.Conclusions: The results show that the youth?s presentations of selves mostly takes place in their profile picture, status updates, groups, fan pages and through their communication with other users on their wall. The borders between front and back stage on Facebook entirely depends on the norms that the reader expects the profile owner to uphold.

This essay describes the phases of funeral rituals between the Syrian/Assyrian, and compares the homeland with Sweden. It describes the stage of rituals according to Victor Turner schema of separation, margin or limin, and aggregation. The rituals religious significance agrees with Clifford Geertz?s theory about the importance of religious beliefs for the human being.

I have made an inquiry about stage communication, small talk and on-stage rhetoric. The essay is divided into different parts. There is a background part that gives a short overview about other research and literature that has been made on the subject. A background has been put together to help you as a reader to understand the complex science can be. Here you will find work written by Dorothy Irving and Åke Lundberg among others.

This report is about the experiments with mixing of the separated water and the vacuum pump seal water at Hellisheiði power plant. This is done to prevent silica scaling and clogging in pipes and reinjection wells as well as eliminating vacuum pump seal water from the plant. The experiments were done in four stages: the first stage comprised of tests with different flows of separated water at 70°C, the second stage was carried out by mixing the separated water at 70°C and the seal water with different amounts of the seal water, the third and the fourth stages were like the first and second but with the separated water at 120°C. The results show that this method is good if the mixture is around 50/50 separated water and seal water, to control the silica scaling in the separated water and to be able to reinject the seal water with the separated water. This does not eliminate the silica scaling in all of the separated water because the amount of separated water is much more than the amount of seal water that comes from the plant. .

During its lifetime, a road goes through a number of different stages; pre-study,inquiry of the road, work plan, documenting stage, building stage and operatingstage. The operating stage is the one that takes the longest time and costs themost. Those have a tendency of becoming unnecessarily high because the projectengineers don?t always take the management and maintenance prerequisites intoconditions.To decrease the management and maintenance costs, the Swedish RoadAdministration SouthEast has been in need of a work procedure that makes theroaddesign engineers take the management and maintenance of the road intoconsideration. This shall be achieved by a checklist where the most commondesigns that lead to increased management- and maintenance costs are compiledand listed.Through interviews with project leaders in management, the most commonproblems have been identified, analyzed and summarized under the headlineswinter-road, vegetation, road equipment and road designs.To elucidate the problem from several points of view, interviews wereimplemented with project leaders in investment and roaddesign engineers.

Emissions of radionuclides to the atmosphere can lead to wet deposition on plants in the event of rainfall. An increased level of radioactivity in the plants may occur due to interception and retention of the radionuclides. If the content of the plants is above the threshold limit value, entire yields may have to be destroyed. In order to prevent contamination or decrease the content countermeasures can be taken. The impact of the biomass, leaf area index (LAI) and growth stage of the plant on the interception and retention is important to know in order to decide which countermeasures to use. Weather may also be an important factor. In this work the interception and retention of 134Cs and 85Sr by spring wheat, ley and spring oil-seed rape was studied.

My thesis is a combination of theory and practice, where theory is meant to create a context and a background for my interpretation proposal. I wanted to ?access? the ideas that are always in the background of the reasoning which underlies both planning in a larger scale, and the design of a place. I wanted to make a ?work of ideas.? In the process of shaping the proposal, I wanted to be deleted from the site itself.

The gap between practise and theory is often described in negative words in teachers? professional lives. Learning study is a model for teachers´ professional development where a theoretical framework is used to enhance practice. The theoretical framework used by teachers in learning study is variation theory. In this study the research object is variation theory and the aim is to present how variation theory becomes a guiding principle to understand teaching and learning processes.

This master thesis concerns whether Swedish non-financial listed firms act in accordance with the optimal capital structure theory and/or pecking order theory. The examined period is 1998-2004 and we discover that Swedish companies neither follow optimal capital structure theory nor pecking order theory. From our results we conclude that there exists no single point of the capital structure which is optimal. Rather it seems as if the optimal point lies in-between an interval from 0 to the industry average, where firms tend to be indifferent to their debt-ratios. Our results show that Swedish companies prefer internal financing followed by equity and as last choice debt issuance..

This treatise analysis what functions light has in theater. It was inspired by Rosalinda Krauss essay Sculpture in the Expanded Field but builds mostly on the following three books Linda Essig Lighting and the design idea (2nd ed), Nigel H. Morgan Stage lighting for theater designers and Francis Reid The stage lighting handbook (6th ed). It discovers nine unique functions of light (performance style, dramatic style, image,illumination, 3D space, 3D form, selectivity, environment, atmosphere) and develops a graphical mapping of them based on a mapping by Reid. The functions performance style, dramatic style, image are superior the others.

This text concerns itself with war, the just war theory, and the application of that doctrine on the ?war on terrorism?. I present different views on the theory's place in the discourse, its relevance for unconventional wars followed by the analyses of above mentioned empirical situation.Particular interest is given the criteria concerning proportionality, both ad bellum and in bello, due to in part its difficult nature, and the attention it has received from others. This paper asks the question: Is the just war theory adequate for analysis of modern war?There are few alternatives.
