Biogas is increasingly used for fuel in for example vehicles and it´s produced in a biogas processconsisting of the steps of pretreatment, digestion and gas cleaning. The pretreatment is a method usedto increase the gas production and / or destroy pathogens. The digestion is the stage when anaerobicmicroorganisms convert bio-mass of a substrate to a raw gas containing about 65% of methane. Thegas cleaning is used to increase the methane content to about 97% so the gas can be used for motors invehicles. The biogas part of the Ekeby sewage plant in Eskilstuna is using multiple substrates.

The purpose with this essay is to look at how categories of "us" and "them" are created, reproduced and categorised. The areas of politics and media are in focus, though they are powerful and influential actors in generating discourses.The method is qualitative analyses of current research and analyses of discourses, contexts and resources from an intersectional perspective. Intersectionality presents a theoretical tool for complex understandings of power as it takes its point of departure in an understanding of power as multidimensional and one where gender, ethnicity and class are constitutive and bearing principals. Intersectional analyses aim to understand how these dimensions are created and changed in relation to each other and how they interact with specific gender orders in specific contexts.The analyse shows that "immigrants" are in a subordinate position compared to "Swedish" when it comes to resources, contexts and discourses. The analyse indicates the relation of power between "us" and "them", where "us" have the power and with that preferential right of interpretation in discourses, contexts and resources.

The aim of this study is to increase knowledge about how a group of newly graduated social workers reflect on the practical daily work and their positions working with clients who are in need of social and/or economic resources. More precisely the purpose is to find out how these seven newly graduated social workers viewed working with clients during theoretical and practical studies. The aim is to analyze which techniques and methods could be seen in these narratives. Furthermore the aim was to find out if and how these seven social workers reflected on the power relation between social worker and client.The material of this study consists of seven semi-structured interviews. Throughout gathering the data and analyzing it, the qualitative method in form of narrative approach was used.

The district heating load is seasonally dependent, with a low load during periods of high ambient temperature. Thermal energy storage (TES) has the potential to shift heating loads from winter to summer, thus reducing cost and environmental impact of District Heat production. In this study, a concept of high temperature borehole thermal energy storage (HT-BTES) together with a pellet heating plant for temperature boost, is presented and evaluated by its technical limitations, its ability to supply heat, its function within the district heating system, as well as its environmental impact and economic viability in Gothenburg, Sweden, a city with access to high quantities of waste heat.The concept has proven potentially environmentally friendly and potentially profitable if its design is balanced to achieve a good enough supply temperature from the HT-BTES. The size of the heat storage, the distance between boreholes and low borehole thermal resistance are key parameters to achieve high temperature. Profitability increases if a location with lower temperature demand, as well as risk of future shortage of supply, can be met.

In recent years, moisture damages have been noticed in rendered, undrained stud walls. The design is built on the principle one-stage tightening which means that there is no air gap in the construction. The damages have occurred when water has permeated through the rendering in leaking connections and fittings for windows, doors, canopies, balconies, terraces and awnings. Behind the plaster carrier, which consists of either polystyrene or rigid mineral wool, plasterboard has often been used as a wind protection barrier. In many cases the wind protection barrier and the underlying wooden studs have been exposed to mould and in some cases even rot.

The main aim of this study is to examine the development policies of Sweden and the European Union from a postcolonial perspective. Sweden and the European Union are increasingly coming to be viewed as normative powers rather than military powers. So how does the colonial past of the western societies affect the policies of today? Are there any signs of the power structures of the past, and if so, how are these power structures manifested in the development policies of today? Since both Sweden and the European Union have come to be viewed as normative powers they are compared with each other to highlight their similarities and differences. The results of the study shows that both Sweden and the European Union can be seen as carriers of western values and interests.

This paper develops a theory for understanding negotiation situations involving states and indigenous peoples. Using relevant constructivist theory as a starting point, the paper develops a theory about understanding the relationship between power and culture implicit in the concept of the state. This relationship is examined in negotiations situations involving states and indigenous peoples. States are constituted by social structure and are representatives of the national culture. At the same time states are actors within the international system and a part of the culture of Westphalia.

This study concerns the complete oeuvre by the British author Helen Zahavi: Dirty Weekend (1991), True Romance (1994), and Donna and the Fatman (1998). Her novels are here read as a trilogy dealing with the dialectics of gender and violence in 20th century discourse, drawing on theories of how the construction of subjects is produced by power, of the relation between power and sexuality.The heroines of Zahavi?s novels try their best to move about in a world where their freedom of movement is limited to their female identity. In Dirty Weekend the protagonist tries to shoot her way out, claiming revenge on every man that is forcing himself upon her. She gains some freedom of movement by refusing subordination, but does not really change the order of power.

The purpose of the essay is to discuss from the theory about the established and the Outsiders if the Culture Centre Blå Stället can serve as a meeting point between the majority of the people and the minority of the people in Gothenburg. The idea of Blå Stället is that it shall work as a house available for everyone and as a cultural meeting point between people in and outside Angered. I argue if Blå Stället really is a place where people from Gothenburg as a whole go or if there are some hindrances for their visions. My study is comprised of interviews with three of the staff at Blå Stället. With the theory about the established and the outsiders I want to show that the division in the city between ?them? and ?us? has to do with differences of power.

The objective of this research was to study how two newspapers in Sweden, Aftonbladet and Expressen are creating an image of the Stockholm suburb Rinkeby. The method used to do the study was qualitative content analysis. Ten articles were chosen, five off either newspaper and were found on the internet homepages of the newspapers on 15 November of 2013 and 27 January of 2014. Several theories were used in the study. Agenda setting theory, a media theory that explains the power of media, Figuration theory developed by Norbert Elias that deals with power struggles between different groups in society.

Simulation is a vital tool during development of JAS 39 Gripen, since money and time can be saved.The Auxiliary and Emergency Power System, AEPS, is a subsystem of the secondary power system in Gripen. It has the function of providing the aircraft with electrical and hydraulical power before activation and after deactivation of the main engine. The system also functions as backup in case of a safety critical problem in the main power supply system. The system basically consists of a control unit and an auxiliary gearbox. The gearbox is driven by an air turbine.

This thesis assignment at C-level is focused on calculation models and prediction methodswhish can be used in the stage we call ?prospecting? of possible windmill locations. Thelocation is southeast of Halmstad at the Farm ?Stjernarpsgods?. The rapport has two mainareas directed towards this task.

In many clinical applications, it is desirable to transmit sensor information wireless. In earlier research, investigation transmit ECG signal using Bluetooth, was performed. However, when Bluetooth has some drawbacks it is of interest to investigate alternative methods, one such method is ZigBee. Bluetooth has higher data rate speed (1Mbps) than ZigBee (250kbps). However, Bluetooth consumes more power.

In recent years it has become more and more evident that man has contributed to much of the climate changes that have taken place during the last century. A major challenge today is to reduce emissions and energy usage at the same time as the global population is growing. To contribute to a better environment, Stockholms Stad has set at target of becoming fossil fuel free by the year of 2050. The construction of new districts is done with this goal in mind; energy efficiency and renewable energy sources are examples of methods to achieve this.Solar energy is considered to be a sustainable energy source and the most common techniques to harvest solar energy in Sweden are solar cells and solar collectors which produce electricity and heat respectively. This report aims to investigate whether an investment in any of these systems would prove to be economically beneficial at Kvarnholmen, a district under construction in eastern Nacka, Stockholm.Since the finished blueprints only cover a small portion of Kvarnholmen, the report examines the possibilities for a house where construction has already begun, Nya Kvarnen.
