Hägglunds Drives in Mellansel, Sweden, manufacture radial piston hydraulic motors foremostwithin applications in the industry. These motors have several sliding contacts, one of these, isthe contact between piston ring and cylinder bore. The radial piston hydraulic motors advantageis to produce high torque in very low rotation velocity, this result in that the maximum slidingvelocity between piston ring and cylinder bore, during the whole stroke, is very low. Theconsequence of this low sliding velocity is that the contact between piston ring and cylinderbore, during the whole stroke, is bound to the boundary lubrication regime. This result in, thatthe piston ring is exposed to wear, thus affect the service life of the complete hydraulic motor.To minimize wear of piston ring, it is essential to determine the oil film thickness between thepiston ring and cylinder bore.

In this essay I have examined how teenager and leaders handle conflicts on a recreation centre in Nacka, outside of Stockholm in Sweden.I have made qualitative interviews with two leaders and ten teeangers. Also I have read researchlitterature about conflicts and how to handle them. Then I have made observations watching how leaders and teeangers communicate and behave.The purpose of the examination is to describe differences with constructive and destructive handle with conflicts. I have also shown how conflicts can give possibilites for the involved people to get to understand themselves, the other parts and the whole complex social behavior better.But that demands that the involved people choose a constructive solution where both parts cooperate, understand eachother and can see how themselves have contributed in developing the conflict.I have worked as an employee at the recreation centre two evenings a week in sex months. During that time I have observed conflicts and different strategies among teeangers and leaders.My conclusions are that conflicts give opportunities for people to grow as human-beeings and get a mentally richer life.

The aim of the following thesis is to examine if the ideology behind the copyright laws of today poses a threat to creativity and the cultural heritage. The organizations Association of American Publishers and Authors Guild are subject to an ideology- analysis which seeks to examine their ideological views on copyright and the possible threat to creativity such a view brings. The conflict between the two organizations and Google Book Search is used as a context where the ideology is being brought to light. Stanford Law School professor, Lawrence Lessigs work is used as theory and an alternative to the examined view on copyright. The result suggests that the organizations see copyright as the only effective incentive to creation and therefore they think stronger intellectual property laws are needed.

This study aims at using discourse analysis to analyze SFI students attitudes to religion and religiosity in an SFI-context. The questions are: How is the discourse constructed and maintained by religion and religiosity of SFI students in an SFI context? How do SFI participants experience that their religion has affected their time at SFI?Using a case study approach, interviews were conducted with a group of SFI students. The results show that the religious discourse in SFI is influenced by the SFI-context and affected based on the current education discourse that exists there. Furthermore, the discourse is designed and maintained by the participants private religious beliefs and the religion of the majority of the group, One canhere speak of a strong social unit forming a plausibility structure The power structure that emerges is that the majority has the power to define the significance of religion and place within the SFI context. In the SFI-context the participants view is that religion is something private that should not be expressed in the school environment.

This essay discusses the use of history, and primarily how the current Swedish society perceives and uses the Viking age. The analysis is based on a literature study as well as a case study of the planned theme park in Fullerö north of Uppsala, Sweden. The aim of the essay is to understand the regional debate which arose in media regarding the planning of Fullerö Park and how it reflects the contemporary use of history. Research about the use of history has become increasingly common in recent years and deals with how history is actively being used in society in order to meet its existing needs. These needs varies among different groups and individuals and results in a multitude of usages, where the interests of the different actors may be contradictory.

Tycho Hedéns Väg in Uppsala has evolved from being a through fare passage and highwayto the oversized road frame running through the city it is today. At the present time, dueto the relocation of the E4 highway east of Uppsala, Tycho Hedéns road creates a barrierbetween the north eastern area of Uppsala and the remaining parts of the city centre. Theroad is designed to endure heavy traffic and high speed limits, generating a surrounding urbanarea were inhabitants are complied to follow the standards set for a high traffic-accessibleenvironment. Furthermore, the heavy traffic has led to the turning of both urban roadsidesaway from the actual road. The aim of this project and proposal is to show the possibilities ofhow the innate features of Tycho Hedéns road can be used more advantageously to mend thecity area of Uppsala.

The study is quantitative and the purpose was to examine the effects of ethnicity and education on three working-related identities and striving among 80 participants. The participants consisted of foreign-born people living in Sweden and people who were born in Sweden, with different educational background. Each groups consisted of 20 participants. The result showed that the highly educated participants had higher professional identity. The participants with lower education level had a stronger colleague identity than the higher educated participants and the Swedish-born participants had a lower identity.

Med Köpenhamnsskolans säkerhetiseringprocess som analysverktyg kan man tolka institutionaliserandet av apartheidpolicyn som en följd av att rasfrågan i Sydafrika under tiden efter andra världskriget säkerhetiserades. Den vita identiteten formades, med ett postmodernistiskt perspektiv, i och med denna process. Den samtida politiska diskursens konstruerade föreställningar om ?vi? och ?dem? blev en förutsättning för samhällets uppfattning om apartheidsystemets legitimitet. I och med apartheidregimens fall reverserades emellertid rasfrågan i säkerhetiseringsprocessen och introduceras åter som politisk fråga.

When discussing local development attention is often given to the problems involved. Factors like decreasing population and inadequate infrastructure are two examples. Local politics has, however, lately been argued to have possibilities to affect its own development and its chances to achieve growth. Some of the most important factors from this debate are to make a community attractive for people and companies, committed leadership, the local business world with entrepreneurialism and a good business climate. These factors serve as a starting point for this discussion where focus is on the possibilities to achieve growth on the local level and the politics that is used for this purpose.To illustrate the chances to affect local growth I apply the theoretical perspective of regime theory and thereby examine the governing coalitions "power to" govern and not "power over" as the earlier theoretical perspectives in the area.

Fire is an important ecological factor, but its consumption of coarse woody debris, CWD, has hardly received any attention. In this study, I investigate the consumption in relation to the time of initial flame exposure and propensity for continued combustion of standing CWD of pine (Pinus sylvestris). Two types of CWD were studied. Firstly, wood that had been dead for one to ten years. Secondly, wood that had been dead for several decades. In the burning experiments, logs of approx.

The aim of this thesis is to study the views of public librarians on the subject of controversial video games and how they work with them at the library. The purpose of the study is to answer these questions: What content is controversial in video games according to the librarians? How do the librarians handle the controversial games at the library? Does it exist a conflict between the users and the librarians about the controversial video games? Is it possible to see any underlying reasons or tendencies in the librarians answers? Five qualitative interviews were performed to answer these questions and the collected data was analyzed using the terms, value rationality and instrumental rationality which were collected from a theory by Geir Vestheim. The results showed that the librarians see violence, sexism and racism as controversial content in video games. They handle the games at the library by limiting the access for children with age limits and by not buying the most controversial games in some cases.

Denna uppsats är en kritisk granskning av Samuel P. Huntingtons modell att förstå världspolitiken utifrån, som han presenterar i boken The Clash of Civilizations and the Remaking of World Order. Granskningen utgår från en analys av hans grundläggande begrepp, ?civilization? och ?clash?, och från ytterligare en analys av hur hans modell skiljer sig från andra modeller om världen. Med hjälp av dessa analyser diskuterar jag rimligheten i den tes som han ställer upp och konsekvenserna som hans förutsägelser och policyrekommendationer får, för att sedan kunna bedöma om hans modell är användbar eller inte.

In 1993 the internal market within the European Union was formed and ensured free movement of goods, services, capital and people. This led to the removal of trade barriers between members of the European Union. When opening up for competition, price differences between countries decreased and more jobs were created. A single currency was introduced by eleven countries in 1999 with the goal of reducing transaction costs, eliminating exchange rate risk and to further simplify trade. In 2001 Greece joined the collaboration and introduced the euro.

The purpose of this thesis was to trace and discuss tendencies in the debate of the computerization of the libraries, in Swedish library press during the period of 1970-1999. The set-out was the issue of how the library journals, as representatives and mouthpieces of a by tradition humanistic profession, coped with a revolutionary innovation related to a field (data technology) which they hadn't any knowledge or even interest in. The examination included three Swedish library journals: Biblioteksbladet with connection to Sweden?s most established library organization (SAB); Bis which is founded upon a socialistic base and; DIK-forum rooted in the union. The analysis of the debate was partly based on three different sets of values related to data and systems development.
