This report is made as a literature review, focusing on the work done to increase understanding of efficiency in the categories of substations and secondary heating systems, with respect to the deviation from the theoretically possible cooling off in the distribution network as well as the economic benefit that appear. The main purpose of a considerable part of the literature used in this report addresses the issue of identifying individual causes of reduced cooling in district heating systems. These literature resources have been compiled and summarized as part of the report.The technology of district heating is associated with benefits such as better use of the energy in a fuel. This is the case of cogeneration plants where serial generation of electricity and thermal energy increases efficiency compared with the parallel generation where heat is generated locally and electricity is generated centrally. Serial generation thus allows for lower primary energy demand.

Syfte/Purpose Syftet med uppsatsen är att undersöka sambandet mellan aktiens omsättningsvolym och dess avkastning under olika marknadsförutsättningar./The purpose with this essay is to observe the correlation between the stock turnover volume and the return under different situations on the market. Metod/Method Den metod som jag har använt mig av är en kvantitativ undersökning. Genom att utföra en kvantitativ undersökning har jag gjort det möjligt att undersöka ett stort antal aktier. Jag har jämfört utvecklingen av 60 stycken, slumpmässigt utvalda, aktier vid både en positiv samt negativ trend av index./The method that I have used is a quantitative study. By execute a quantitative investigation I have been able to study a large amount of different stocks.

X-rays are a potential risk for animal health care personnel. The present study will examine the risks for scattered radiation to the personnel, if no lead gloves are used when holding an animal during the x-ray examination. Furthermore, how the impact of the exposure values and body parts examined, affect the scattered dose to the hands of the holder. Also, the distance between the animal and the hand that holds it was evaluated to see the impact on scattered radiation exposure. Tested by a survey, to animal health care students, the frequency of the usage of lead gloves in Swedish animal hospitals was studied. According to the results from the analysis, animal health care personnel don't need to use lead gloves every time they hold an animal or a cassette during x-ray examinations.

What role does the state play in economic development? This thesis seeks to investigate the relationship between a strong state and economic development. To define the concept of a strong state I focus on the relationship between the scope of state functions and the efficiency of which these functions are implemented. The concept of a strong state is in this thesis defined as the efficiency of the state functions. By using a database constructed by three economists; David Kaufman, Aart Kraay and Massimo Mastruzzi as a measurement of a strong state I test the relationship with economic development empirically.

During the twenty-first century the price of forest land in Sweden has increased heavily. Buying forest land has become more common and the stakeholders have grown in number. The countries around Sweden have through the globalization become connected in the market of round wood and wood products. The price of forest land and round wood are also close connected. The goal with this report is to make a comparison of forest land prices between Sweden, Denmark, Norway, Finland, Estonia and Latvia and to see how the prices have developed in the period 2000-2011. The prime factor in the comparison, except the direct price difference between the countries, is the round wood prices. The round wood prices give information about the economic situation in the countries and play an important role in the return on the forest land. The prices of forest land shifts heavily between the countries.

Research about what differences and similarities exists between UNHCR and UNRWA in the opinion of a refugee?This examination focuses on a study between The United Nations High Commissioner for Refugees (UNHCR) and THE United Nations Relief and Works Agency for Palestine Refugees in the Near East (UNRWA). Both organizations are UN-related and are in charge of refugees, however they differ by the fact the UNHCR controls all of the world?s refugees with the exception of the Palestinian refugees, for which UNRWA. The aim of this work will be to examine the definition of refugees as well as their entitlements and in what way they differ depending on which organization they belong to.As theory I have, among others, used Rainer Bauböck?s book ? Transnational Citizenship?.

At present indoor tethering of dairy cows is still common but is not predicted to take part of modern dairy production. When conducting scientific studies of cattle it is generally necessary to tether the animals to maintain a controlled environment. Studies confirm that tethering and confinements of cattle severely affects the development of stereotypies in cattle. The feeding regime and feeding level have an immense affect on the stereotypi level in cattle. The aim of this experiment was to study dairy heifers that had never been tethered before the start of the experiment, to evaluate the affect of tethering on the development of stereotypies and the impact of the feeding regime on the behavior of the animals. Sixteen dairy heifers were tethered in a tie stall and divided in two groups with different treatments. Heifers in treatment E were fed restrictedly with silage and treatment EH was fed with the same amount of silage but also straw ad libitum.

This in an essay concerning the use of humor in male communication. Primarily, I have focused on studying how jokes can be used as a sanction for the training of members in a (male) group. I have found great inspiration in Goffman?s thoughts on a social face and the use of humor to protect this perceived face.Initially I started to reflect on men?s reluctance to discuss masculinity and their thoughts about the meaning of being a man. Every time I tried to hold a serious conversation, my male friends made a joke out of it.

The purpose of our research was to explore the social situation of unaccompanied children. We also aimed to reveal the relation between their social situation and their identity development. The overall purpose were to describe their social situation, the value of significant others, how different languages influence their identity development and finally how their origin affects their future dreams.In order to achieve the best result in our research a qualitative method was used. This was based on qualitative interviews and was disposed around a very loose set of questions in order to let the interviewees lead the way. The analysis of the result was conducted on the basis of a set of theories and concepts in order to understand the identity development.

Management of large carnivores involves more than just the management of animals, people also have a large influence. The Swedish parliament decided in 2009 that the county boards should use co-management to a greater extent in management. This shows how important human dimensions are.We know from previous research that the majority of people in Västerbotten are positive toward large carnivores and the management done by the state, however there is a negative minority which should not be neglected. This paper contributes with an examination of attitudes toward large carnivores, wolf, bear, lynx and wolverine, in Västerbotten County. The data for this study were derived from a survey that was sent out to 150 randomly selected persons in every commune in following counties: Norrbotten, Västerbotten, Jämtland, Västernorrland, Dalarna, Gävleborg and Stockholm.

Today's consumers are demanding more and more from companies and are no longer as easy to im-press as they used to be. It is now the consumers that hold an increasing amount of power over com-panies and not the other way around. This change in consumer behaviour has caused an identity crisis for traditional advertising, and companies are now searching for new ways of reaching their target audience. The purpose of this combined qualitative and quantitative case study is to examine possible risks and possibilities that a retailing company face when communicating through Facebook. Data has been collected through in-depth interviews with company representatives combined with a quantitative study of the company's Facebook followers in order to answer the questions of (1) which possibilities and risks a retailing company face through the use of a Facebook fanpage and (2) if there is a differ-ence in the attitude and behaviour of active respectively passive followers that may have been caused by a retailing company's marketing communication on Facebook.

The public sector in Sweden outsources its core business to a very large extent, whileinsisting on running its IT operations internally in a traditional way. IT as a service ingeneral and cloud computing in particular has become incredibly popular in recentyears, offering cost efficiency and greater ability for the business to concentrate on itscore activities, which is why it should be a promising alternative to the traditional wayof running IT internally. To achieve an understanding of why IT as a service has yetto take off in the public sector, a study of its use of IT/IS, what the effect of IT as aservice is, and the opportunities and challenges that cloud computing represents, isnecessary.The study, which was conducted using a qualitative hermeneutic approach, was initiatedby a literature review, followed by six in-depth interviews with five respondents,all of which hold many years of experience in the area. The outcome of the interviewsindicated that IT as a service should represent a promising and feasible way of reachinghigher levels of cost control, and a greater focus on core activities. Furthermore,the results indicated that Swedish legislation along with a high level of businesscomplexitymight be reasons for the low amount of IT as a service in the public sector.Through careful analysis and examination of the business? current situation, as well ascomprehensive knowledge of Swedish legislation with regards to the implications ofLagen om offentlig upphandling, the public sector can avoid IT as a service becomingmore expensive and more complicated than necessary, and achieve cost efficiencyalong with a greater focus on its core activities through it.Future research could examine the possibility of a framework for the integration ofcloud services within the public sector?s IT/IS environment, and whether there is aspecific size of a cloud implementation at which it?s more cost efficient to go withtraditional IT operations..

To make wave power more competitive on the market Uppsala University leads projects that examine how to accomplish better efficiency in the production. One of these projects is described in this report and examines whether it is possible to make the production of dovetails more efficient by using an industry robot of type ABB IRB6000 S3 M91. This project is using an already presented working method, from a previous project, which involves that the robot picks up the dovetail and moves against fixed cutting machines where the dovetail will be drilled, threaded and milled. Drilling and threading are the sub operations that will be examined in this project where experiments are made with the presented working method and with equipment from Uppsala University.Experiments show whether it is possible to drill the holes in the dovetail within specifications by using the specific robot and the presented working method. The threading operation is examined theoretically if it is possible to accomplish by using the same working method.

This literature review aims to investigate, expose and explain August Strindberg's religious position in his partly autobiographical work Inferno, published in Swedish in 1897, in relation to Peter Berger's socialization theory. Strindberg says in the beginning of Inferno that he goes from being an atheist, occultist and Swedenborgian to finally return to his ancestral religion, Christianity. This is questionable, as Strindberg seems to be religious in its atheistic era, and occultist during his Christian period. Strindberg's own religious views seem not always match what he portrays, compared to what he writes in his correspondence and diary entries. This literature review aims to highlight the influences of Strindberg affected to clarify his religiosity which is implicitly and explicitly depicted in Inferno.
