New energy resources that can replace petroleum diesel are needed and biodiesel may be an excellent substitute. During storage and use, biodiesel can oxidize and form peroxides, leading to degradation of the fuel. It is therefore important to determine the peroxide content of the fuel. In this thesis the triphenylphosphine method, which involves GC-MS analysis has been compared to the standard iodometric method which involves titration with sodium thiosulfate. Working standards were made to see how well the iodometric method worked and also in order to make a calibration curve in GC-MS.

The purpouse of this study is to find out how and if a Content Managment System (CMS) can benefit from applied User Experience Design (UX). A work project has been executed where a client wanted the students to create a user friendly CMS for adding content to a global hotel review site. A prototype of a CMS was created based on literature studies about UX and CMS. The prototype of the user friendly CMS was then tested through user tests and interviews with key users. After input from the key users the prototype was changed until the users were satisfied with it..

This paper investigates the presentation of Islam in textbooks used in the study of religion in high schools. The papers focus on two main questions concerning the ways in which Islam is presented in the analysed textbooks, and how the new curriculum has influenced the portrayal of Islam in the materials. Here, the paper utilizes a method of critical discourse analysis with Faircloughs three-dimensional analysis. The paper then concludes that the presentation of Islam is negative in nature, with the content and view of Islam having been simplified and stereotyped. Often the textbooks studied frame Islam as being an aggressive and oppressive religion, especially in matters con-cerning women.

The aim of this master thesis is to evaluate the performance of the content-based image retrieval system ImBrowse from a semantic point of view. Evaluation of retrieval performance is a problem in content-based image retrieval (CBIR). There are many different methods for measuring the performance of content-based image retrieval systems, but no common way for performing the evaluation. The main focus is on image retrieval regarding the extraction of the visual features in the image, from three semantic levels. The thesis tries to elucidate the semantic gap, which is the problem when the systems extraction of the visual features from the image and the user?s interpretation of that same information do not correspond.

With a growing population on earth the amount of end-of-life vehicles (ELVs) and other scrap steel increases. The European Directive 2000/53/CE? requires a minimum of 95 % reuse and recovery and 85 % re-use and recycling no later than 1 January 2015, for end-of life vehicles. This imposes a need for more efficient recycling and recovery. Despite this shredder residue (SR) is commonly land filled.This report investigated the magnetic fines residue generated at Stena Metall shredder facility in Halmstad, Sweden.

This project investigated how elevation and vegetation type influences variation in plant litter phenolic content and protein precipitation capacity among and within common plant species for two different vegetation types, heath and meadow, in a subarctic ecosystem in the Abisko region of northern Sweden. As nutrient availability generally decreases with increasing elevation as a result of decreasing temperature, I hypothesised that phenolic content would increase with elevation and be higher on the heath than the meadow. To test this, the total phenolic content and protein precipitation capacity was estimated in leaf litter from 13 species in both heath and meadow vegetation across an elevational gradient ranging from 500 to 1000 meters above sea level (m.a.s.l.) in the study region. The results showed that elevation and vegetation type both had a strong impact on both variables. Total phenolic concentrations decreased with elevation for the meadow, and were greater for the heath than the meadow.

With this study we aim to learn more about the process in creating an identity onFlashback Forum. We have observed four members of the forum to find what themesdefine thier way of making an identitity. Besides to our empirical material we foundearlier research that could support our study. The methods we used was qualitativesince we wanted to get a deep understandning for their behaviour. We found thattheese three themes were central: Language, Content and the feeling of beingAnonymous.

This qualitative study is done with the purpose of creating understanding for the theoretical democratic content in educational materials for Civic Education courses 1a1 and 1b during GY-11, so teachers create an intentional approach when using educational materials in their democratic education. This was motivated as important considering the reduction in obligatory Civic Education for the vocational programs. The study was conducted using a hermeneutic qualitative reading method where the educational materials, more specifically two series with one book for each course, was read with purpose of creating understanding for the democratic content according to ideal democratic models: deliberative democracy, participatory democracy and electoral democracy. A text voice analysis was also conducted using Bakhtins theory of dialogic and monologue text that contributed to the general result concerning the democratic content. The results show that the electoral democracy ideal is dominant in all educational materials, there is hence no striking difference between the democratic content in 1a1 and 1b educational materials.

Purpose/Aim: The purpose of this thesis is to define and analyse how Swedish record companies work with digital musical content distributors. A more narrow aim is to show how the record companies and with the digital musical content distributors iTunes Music Store and Spotify create incentives for consumer?s to use legal digital music channels through the Internet. To further circle the core of the problem following questions have been asked: How does the record companies provide iTunes Music Store and Spotify with digital content and what is done by the record companies to retain control over the material? How do the record companies view digital musical sales and what incentives are given to consumers to buy music digitally? Finally, What position of power do iTunes Music Store and Spotify have on the digital content arena?Material/Method: The data collected for this thesis is retrieved through personal interviews with representatives from three of the four major record companies Universal Music, Warner Music and EMI and their Swedish branches.Main results: The consumer?s access to digital content through iTunes Music Store and Spotify is of the utmost importance and is a prerequisite.

Problem definition and purpose: A debated question in journalism today is if the mass media have the power to affect norms and values in the society. There are therefore many who believe that the media must works for democratic and equitable news coverage. Studies have shown that there are still many differences in how women and men are being portrayed in the Swedish media, even if Sweden is one of the most equal countries in the world. This inequality may affect the democracy and equality in the society negative.Previous studies have mainly been using gender as the only explanatory factor to explain the difference of coverage between men and women in the news content. The purpose of this study will therefore not only be to compare the coverage of the Green Partys two spokespersons, Åsa Romson and Gustav Fridolin, from a gender perspective but also to take in count other factors that could contribute to differences in the news coverage.Method and material: To find an answer to the purpose of this thesis a quantitative content analysis have been done on a total of 238 news articles in which Åsa Romson and/or Gustav Fridolin occur.Main results: The results of the content analysis show that Gustav Fridolin occurs more frequently in the news than Romson does, and that the articles he appears in is lager than the articles in which Romson appears.

This study?s aim was to explore how the social media Twitter is used by Swedish political leaders and how they manage the relationship between having both private and public conversations in a new public sphere, the social sphere. In Sweden, studies in this area are yet to grow. We achieved our aim by responding to our three questions at the issue: What kind of content is published in each of the politicians Twitter stream? Are the politicians private or public persons on Twitter? Are the politicians using Twitters interactive functions? We conducted our analysis by performing a quantitative content analysis.

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.

The aim of this study was to investigate how the content of the syllabus for Physical Education and Health at Uppsala University correlates to selected parts of the core content of the Gy11 syllabus for Physical Education and Health 1 in Upper Secondary School. Furthermore we aimed to investigate the perceived competency of recently graduated and still studying teachers of Physical Education and Health within the selected parts of the core content.The selected parts of the core content are:Exercise, sports and outdoor activities that develop a comprehensive physical abilityThe adjustment of tension and mental training.The methods used were a qualitative comparative text analysis of the syllabuses for Physical Education and Health at Uppsala University and Gy11 Physical Education and Health 1 in Upper Secondary School, as well as a quantitative survey conducted with recently graduated and still studying teachers of Physical Education and Health.The results were that there is an obvious correlation between the content of the syllabus for Physical Education and Health at Uppsala University and the Gy11 syllabus for Physical Education and Health 1 in Upper Secondary School. Moreover the survey shows that the respondents felt confidence in their ability to teach exercise, sports and outdoor activities that develop a comprehensive physical ability. The survey also shows that the respondents felt less confidence in their ability to teach the adjustment of tension and mental training..

This study was made on former agricultural areas that had been planted with spruce or pine, in the county of Västerbotten. The goal of the project was to investigate suspected deficiency of boron in these areas. Several objects have been reported for possible deficiency and some of these have the characteristic symptoms of boron-deficiency. The hypotheses are that 1) Boron deficiency is present at several of the investigated objects. 2) Planting of forest on cultivated postglacial sediments leads to a successive podzolisation with a decreasing content of organic matter in the mineral soil, due to decomposition, and a decreasing pH in the soil, even on locations that have been added lime. To be able to confirm or reject the hypotheses a number of tests were performed.
