When a combined heat and power plant produces heat and power it often faces a deficit of heat load during the summer or other periods of time. This heat is often unnecessarily cooled away or the power production has to be reduced or shut off. If it is possible to store heat from periods with low heat demand to periods with high heat demand one can get many benefits. Among these benefits are: increased power production, decreased operation with partial load, uniformly distributed load.To be able to store heat in situations like this long-term thermal heat storages are needed. In this thesis five different types of stores are presented: rock cavern storage, tank storage, pit water storage, borehole storage and aquifer storage.

The present essay concerns the Levinasian understanding of responsibility in relation to the two spheres that Levinas introduces in his second major work Otherwise than Being or Beyond Essence, namely the Saying and the Said. The essay investigates some of the different meanings that the concept responsibility takes on in regard to these two spheres, and thus also in regard to the separation between the ethical and the political that is apparent in the book. Is it possible to find a politically uttered responsibility in Levinas Otherwise than Being or Beyond Essence?The essay wants to emphasize the continuous transition between the ethical or the Saying and the political or the Said, and vice versa, with the purpose of showing how the two spheres may be conceived simultaneously. By posing the relationship between the two as a reciprocal rather than a oppositional one, the essay aims to suggest that an understanding of responsibility at once must be ethical and political.

Abstract?Political participation by the citizen?- Citizen proposals in Karlstad municipalityEssay in Political Science, C-levelAuthor: Tobias GustafssonTutor: Michele MichelettiIn Sweden the political parties are losing more and more of their members. That in combination with a tendency that the participation in the elections is getting lower is a problem for the representative and parliamentary political system in Sweden.In order to strengthen the democracy in Sweden and to make the gap between the citizens and the elected smaller there has been some democracy-projects. The purpose of these democracy-projects is to make the political participation by the citizens, between the elections, higher. One of them is ?citizen proposals to the municipality?.The purpose of this essay is to examine this democracy-project in order to see what influences it might have on the local democracy.

John A. Warden III is one the most mentioned air power theoretic of his time.He has written a number of theories concerning air power and the best way to use this to win wars.The author of this paper gives a short resume of what he consider are the central thoughts in John Warden´s theories. These thoughts result in four factors; Enemy as a system, centre of gravity, parallel attack/concentration and finally air superiority. These factors are then being used to inves-tigate if NATO used Wardens theories during the Kosovo war in 1999.The reason for the author to choose the Kosovo war specifically is due to the fact that NATO during the war only used air power as an instrument to get Serbia´s president Milosevic to the negotiation table but also the fact that this would turn out to be quite a challenge for NATO.The conclusion is that out of the four factors only one is traceable throughout the entire operation, and that is air superiority. Regarding the other three factors they can only be found in parts of the operation..

The purpose of this essay has been to compare different constitutions, and their outlook on citizenship, rights, obligations and natural duty. This has been done in the light of the political philosophy, in order to give the answer to four questions. These questions are: Which rights and obligations can be seen in the constitutions, and how can it be interpreted. Can there be signs of any political philosophy in the constitutions?  Are there any differences between the constitutions regarding citizenship, rights, obligations and natural duty? If so, what are the differences? Can the rights be seen in a further extent than the obligations in the constitutions?I have conducted a qualitative comparision study and analyzed the political philosophers and made a classification scheme of their views.

This essay is about power, democracy, solidarity and equality in preschool. I examine three different situations to determine if I could have acted more sensibly in my interactions with the children. I portray: a ?children?s choice meeting? where children select an activity, a so-called emotional gathering and a dialogue at the lunch table about a popular movie that we plan to watch together afterwards. The purpose of this essay is to examine which norms and values form the basis of my actions, and if so, how these lead me to use my power to shape the children.I have chosen to use hermeneutic and norm-critical perspectives where I investigate and examine my norms and values and how I react and act, both consciously and unconsciously.

The aim of this work was to study if the edge of the forest is more resistant to heavy winds than the trees located further in from the edge, and how this edge effect changes between different types of tree species and site types. The data was collected from an electric power line going from the north to the south of Sweden. The mean value of the clearcutted area around the power line was 120 meters. The main direction of the storm in January 2005 was west-southwest and thus the power line was a perfect place for gathering a large data set. The main parameter studied was the damage frequency at the edge of the forest compared to the trees located further in from the edge (up to 100 m from the power line). Tree species mixture, soil moisture class, soil type, topography, stand height, stand height of the stand on the other side of the power line and wind exposition was estimated. The results showed a distinct edge effect. The edge of the forest had clearly lower damage frequency for all tree species. A marked difference was observed between tree species and damage frequency.

North Korea is considered to be the most autocratic dictatorship in the world today. Its citizens are denied their most basic human rights and North Koreas ambition to pursue nuclear weapons is looked upon with great fear from the international community and the US in particular. Some experts say that the threat from North Korea is far greater than the one possessed by Saddam Hussein. Although North Korea seems to inhabit all the necessary criteria for an US military intervention the United States has openly declared its diplomatic ambitions with the state. Why?With the use of realist and social construction theory this study will bring clarity to why the United States prefers diplomacy instead of a military intervention.

The aim with this paper is to examine the political background of the schools comission to integrate pupils with special needs in the public school. These following questions are examined: What political documents are the elementary? Which ones are juridically binding for the schools? What are the experiences for  parents of children with special needs in the school? The method used for this paper is mainly litterature-studies. The four documents which are examined are: skollagen, Läroplanen 94, FN:s barnkonvention och Salamancadeklarationen. The theoretical frame for this paper is political documents, curriculums and how schools concretize the special education.

The purpose of this essay is to analyze the democratic views in the two latest party platforms, belonging to the two Swedish political parties Vänsterpartiet and Sverigedemokraterna. This by applying Robert A. Dahl's democracy model, Polyarchy, and Carol Pateman's democratic Participatory model, on to the party platforms. By doing so, my hopes were to determine if the two political parties can classify themselves as democratic parties. The result shows that both Vänsterpartiet and Sverigedemokraterna meet the majority of the democratic demands created by Robert A.

The wind power increase of Gotland as well as other parts of Sweden during the last ten year period has meant that this renewable energy source has increased its share over other fossil sources. The year of 2011 became the first when the wind power produced more energy than an average nuclear reactor. Now that wind power is in an expansive phase, the land issue will be of great interest. Land with good wind resources will be of interest to wind energy developers. The problems that this essay is based on are; how can landowners altering the economic conditions at a wind power establishment? What opportunities and obstacles exist for landowners who choose to set up wind power on their land? The purpose of this essay is to highlight the economic conditions that exist for landowners for the establishment of wind farms, with regard to compensation for the leasing and return on invested capital.

Minimizing power consumption is a critical part of many embedded design projects. Thechallenge is to limit the power consumption of the system and at the same time providesatisfactory service to the user. With regards to microprocessors, the main way of limiting powerconsumption during program execution is to adjust the frequency and the voltage at which theprocessor operates.To enable the implementation of real-time scheduling with support for dynamic voltage andfrequency scaling, an exhaustive study of the Freescale i.MX31 embedded microprocessor isperformed. Specifically, the power consumption relationship to all relevant frequency andvoltage settings is investigated. In addition, to enable frequency and voltage scaling in a real-timeenvironment, a complete timing analysis of proposed voltage and frequency scaling methods isperformed and their suitability for use in real-time systems is evaluated.To integrate voltage and frequency scaling capability into OSE RTOS, a software module hasbeen developed for this operating system.

The background of this paper is the dual role that the social worker can have, of beeing both supportive and controlling in the meeting with clients. It is also about the power the social worker can have, how they handle the power in their profession and how they remain to it in the relationship with the client. The study is qualitative and built on interviews with eight social workers that work in different areas in the social services. We have chosen to see this dual role as if the social workers have to, in their daily work, handle the roles as one authority role and one supportive role towards the client.The purpose of this study is to understand how the dual role as the social worker has in the profession, as a helper and a authority, is expressed in the work and relationship with the client. We have turned this purpose into two questions: How do social workers with authority remain to the dual roles of the profession? How do the social workers describe and understand power?We don´t want to generalize in this study, we want to give an example of the social workers own experiences about the dual role.

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.
