Svensk Växtkraft is the owner of the biogas plant in Västerås. The company is planning to increase their treatment capacity at their biogas plant. In connection to this work it is also possible to make some energy saving changes to the biogas plant. The objective of this study was therefore to make an electricity and heat survey of the biogas plant, a detailed study of the heat consumption in the sanitation step and also a comparison of energy consumption with the present sanitation method and an alternative strategy where the waste is treated in 55 °C during 10 hours (the current method is heating to 70 °C during 1 hour). The energy survey was conducted in close collaboration with staff at the biogas plant. The current during normal operation was measured, power was calculated and multiplied by the time of usage to obtain the energy consumed.

The DISA method is a universal program developed for teenage girls to prevent depression. The program includes cognitive behavioral techniques are suppose to change negative pattern of thinking, give practice of communication, strategies of problem solution and exercises to strengthen the social network. The purpose of this study is to find out how a group of teenage boys were affected by the DISA program and what factors that may have impacted the outcome. Material from three different studies have been used, a quantitative study in terms of data from self-assessment form CES-D, materials from two semi-structured focus group interviews with the boys and material from a questionnaire filled out by the boys on two occasions during the DISA method. The result of the CES-D indicates that the boys had less depressive symptoms after the final group meeting compared to the first group meeting and also a year later. Analysis of the material from focus group interviews and questionnaire have been made from a communication theory and systems theory perspective and indicate a shift to greater cohesion in the group and demonstrates that communication between the boy-group and group leaders had importance for the outcome.

In today?s fast growing and closely connected society, a reliable and energy efficient transportation system is more than ever desirable. Nowadays the significant part of the transportation sector?s energy demand is supplied by fossil fuels.Improving energy efficiency in combustion engines will result in reduction of fuel consumption and CO2 emissions. A modern internal combustion engine has an efficiency of 30-45 %, where the most energy loss occurs as result of heat losses in the exhaust and cooling systems.

The purpose of this study was to examine the use of manipulative materials in mathematics education with the main focus on grades 4 to 6. With the use of a phenomenological approach all the aspects of this phenomenon was examined. Qualitative interviews, participant observations and comparative content analysis of textbooks has been conducted to investigate the use of manipulative materials in mathematics education. The results indicates that the teachers that were interviewed possesses good knowledge of this teaching method. However these teachers struggled to find time to put this method into practice and there was not enough teachers to attend these classes.

The purpose of this study was to investigate the relationship between locus of control and behavior in a work group. The investigation was performed using two methods, self-report and observation, which were used in order to provide a description of how the individuals experienced their own behavior in a group context as well as of how they actually could be observed to behave. The 31 participants were divided into five groups. During the procedure each group received a task, which was to be discussed and solved by the group members together. Observations were carried out using IPA.

Studies conducted on event marketing have mainly focused on larger events. Managerial implications, marketing techniques, and theories in the field have hence dominantly addressed events of larger nature. Event marketing however is a growing phenomenon in the marketing mix. Brands are using event marketing to a greater extent. Brands are increasingly using small events as a marketing tool in order to create brand awareness and brand image; this goes for both small brands and large brands.

The report aims to investigate how well a certain type of affordable embedded single board computer can hold up against today's more expensive computers in a computer system by doing various tests on a system with the specified requirements. The system has a Raspberry Pi as the single board computer which task is to control a camera based on coordinates obtained from a server as well as capture and stream a video signal on a network.The researches were conducted to check how much network traffic a single-chip computer sent in different video formats and how much CPU utilization was required. Studies were also made to ensure the accuracy of the camera control. The researches have been experimental, where several tests have been performed and analyzed.The results show that a sufficiently good accuracy can be obtained from the camera steering unit, in which two different servos have been investigated. When the video format MJPEG and H.264 are used, the single-chip computer is able to transmit a video signal up to 1280x720 at 15 fps.

The aim of this study is to compare the modernist novels Astarte (1931) by the Swedish writer Karin Boye with Estación, Ida y vuelta (1930) by the Spanish author Rosa Chacel and the reception of these literary works in contemporary academic research. The theoretical ground of the study consists of feminist and critical theory, with traits of discourse analysis.Astarte and Estación were in large part forgotten and ignored by the Western Canon of literature during most of the 20th century, but have lately gained more attention as important modernist novels by researchers (from the feminist, poststructuralist or hermeneutic theoretical fields) who primarily examine the experimental forms figured by the texts in relation to the deconstruction and shattering of human homogenous ?essence?.The results found in the study show that the literary forms of both novels can be associated with a kind of illusion rapture, which relate to the modernist inclination to what Frederic Jameson calls artificial narrative; a form technique that points back at itself to emphasize its own characteristic of being a constructed and subjective illustration of reality. The contemporary interest in these artificial literary forms expressed by Astarte and Estación is therefore probably a consequence of the vibrant academic debates carried out during later decades concerning the conception of human gender and identity as construction and performance. .

As the European Landscape Convention is brought into action, planning in Sweden has got to become increasingly considerate of the landscape and its character. To render this possible, a basic requirement is that we find a functional method for analysis. The Landscape is a synthesis of the interplay between place and man. It is made up of our physical environment and shows the result of our actions throughout history. Our surroundings affect us in many ways, financially as well as emotionally. This is why an analysis of the landscape has to be inclusive of many types of information. I have performed a landscape analysis, according to the British Landscape Character Assessment-method, in Svedala kommun.

AimThe aim of the study was to develop a method for the survey of play movement demands and temporal patterns in order to enable a descriptive study of the defensive players in American Football. The overall aim was to  improve the understanding of how American Football is played to create opportunities for enhancement of current or developing new training methods to better suit football.MethodFifty plays from a Division 3 college football game on video from 2005 was divided into sequences of action for one player each from the defensive line, linebackers and defensive backs and analyzed with the video analyzing software cSwing. Every players sequence of action was recorded in a spreadsheet and noted on a scaled football field where distances were measured and together with time stamps from cSwing velocity was calculated.ResultsUsing this method it was possible to describe the play movement demands and temporal patterns which was the main task of the study. The defensive end worked on an average 4.61 seconds per play, the distance was 12.4 meters and average speed 2.5 m×s-1. The linebacker worked on an average 4.35 s per play, 13.7 m and at a mean speed of 3.0 m×s-1.
