Detta examensarbete är utfört vid Hägglunds Drives AB i Mellansel där man utvecklar och tillverkar hydrauliska radialkolvmotorer som Compact, Marathon och Viking. Compact motorn har problem med läckage vilket lett till att Hägglunds Drives AB beslutat att studera det problemet närmare. Syftet med arbetet är att experimentellt studera läckageproblemet. En testrigg för radial tätningar har tagits fram där olika tätningar kan testas. Testriggen kan variera temperaturen på oljan, trycket i tätningshuset och det dynamiska radialkastet.

The globalization of political and economic processes is a growing moral concern for theologians and political philosophers alike. My thesis aims to outline, analyze, and compare church studies of globalization with global theories of justice.To do this, I draw upon recent studies of globalization made by the World Council of Churches (WCC) and the Lutheran World Federation (LWF). The WCC and LWF are two global reaching church organizations. They have a common aim of uniting churches for ecumenical dialogue and are involved in social, economic, political, and ecological questions. The WCC and LWF analyze globalization by applying biblical and theological principles from the Christian tradition.

This thesis deals with the theories of ecological and environmental justice and applies them onto Swedish politics. Confronting the divide in the literature between anthropocentric and ecocentric perspectives, its aim is to seek points of agreement within this important field of environmental politics. In the theoretical discussion, definitions are made of the concepts sustainability, justice and responsibility. These definitions try to link ecological and environmental justice arguments with a focus on the global level.The object of analysis is the former Swedish governments? bill ?Common responsibility: Swedish politics for global development? which was accepted in 2003.

Resande, globalt engagemang och arbete utomlands av olika former är företeelser som förändrar människors syn på världen. Dessa tillhör samtiden och de blir därmed aktuella och relevanta att diskutera. Att vi lever i en global värld påverkar våra livsvillkor och innebär i sin tur nya möjligheter och förutsättningar för individen. Begrepp som är centrala att diskutera blir därmed livsstil, engagemang, svenskhet och världsmedborgarskap..

Syftet med studien var att undersöka om det fanns något samband mellan global självkänsla och subjektivt välbefinnande bland svenska ungdomar. Hänsyn togs till ålder och kön togs när 142 elever enkäterades på en gymnasieskola. En bivariat analys gjord med Pearsons korrelation visade att det fanns ett starkt samband mellan global självkänsla och subjektivt välbefinnande. Vidare visade en multiple variansanalys (MANOVA) att det fanns signifikanta könsskillnader gällande subjektivt välbefinnande, men inte global självkänsla. Med multipel regressionsanalys (MRA) kunde det slås fast att kön hade ett samband med subjektivt välbefinnande, medan självkänsla kunde prediceras utifrån ålder.

The company LightLift Esystems AB manufactures patented motorized lift systems for the illumination of halls with high ceilings. The company wants a new design for singular heavy lights in order to be more competitive.This project consists of the development of the new design under the requirements and specifications imposed by the company. The new design must support lights up to 300kg and keep the overall dimensions as low as possible without modifying the driving unit.This document contains all the designing steps followed to reach the final solution as well as the material selection, manufacturing process and assembly of all the parts that form it.The solution obtained shows to be very competitive with other alternative products, since this new design triples their maximum load capacity while the dimensions are very similar.In this context, the optical appearance was also very important to the company and so it was another main objective of this project. From an aesthetical point of view, the final solution proves to be very compact and versatile since it can either be hidden behind a false ceiling or covered by a plastic case that gives the design a very nice look.Finally, the solution achieved fulfils all the requirements and specification previously imposed. It is reliable, compact, cheap to manufacture, easy to assembly and it has a good optical appearance. .

Examensarbetet utfördes vid produktionsenheten för Hägglunds Drives AB i Mellansel, Ångermanland. Syftet har varit att föreslå förändringar inom produktionssystemet för att den totala ledtiden för hydraulmotor Compact CA skall reduceras. Arbetet har baserats på en analys över hur produktionsstyrning och orderhantering skall fungera för att en ledtidsreducering från fyra veckor till nio dagar skall vara möjlig. Ledtiden har i arbetet definierats som den tid som åtgår från att en order läggs fram till att en motor är leveransklar till kund. Vidare har arbetet fokuserats på de sex huvuddetaljer som ingår i varje motor och som tillverkas från råämne till slutdetalj.

Chapter 1 defines the aim of the project and gives a general orientation about ground heat extractors. In chapter 2 physical processes that could be expected to be involved in the heat transport around a ground heat exchanger are discussed. It is shown from a literature study what amount of moisture transport due to thermal gradients there could be expected in a ground heat exchanger. The conclusion is drawn that the moisture gradient (Sr) is of same magnitude as the driving temperature gradient (°C). At the expected amount of increased moisture around the pipes the moisture transport could be considered to have a little effect on the brine temperature.

IS/IT-strategier ligger till grundlag för tillämpningen och nyttan av informationssystem samt informationsteknologi i en organisation. Det är en övergripande plan för verksamhetens användning av IS/IT-stöd, och har stor inverkan på organisationers effektivitet. Globala verksamheter opererar i olika miljöer och länder, något som behöver tas med i planeringsprocessen av en IS/IT-strategi. Uppsatsen behandlar de faktorer som har inverkan på utformandet av en IS/IT-strategi i en global verksamhet. Tänkbara interna och externa områden från IS/IT-miljön samt verksamhetsmiljön granskas, för att sedan analyseras utifrån den globala organisationens förhållanden.

This thesis describes the universalization, improvement and further development of acompact crane support frame for flatbed trucks. The work has been conducted at Eloch Fordonsteknik AB (henceforth EFAB) in Uppsala.The aim of the work has been to shorten the assembly time of the product. By doingso, the product can be kept on shelf, which in turn results in shorter lead time. Thishas been done by universalizing the support frame to be compatible with most of thechassis EFAB works with. Additionally, the entire construction has been made lighter,which will make it a more attractive choice for customers.A pre-study was conducted and information was gathered internally, as well asexternally, in order to ascertain that no limitation or possibility was overlookedduring the course of the project.One such limitation has been the geometry of the truck bed that the support frameshall be compatible with.

Purpose: The purpose of this study is to find out how much influence underlying factors have in connection to the internationalization of Born Global firms. Methodology: This study has a qualitative approach in which data is obtained mainly through interviews and secondary data which consists previous theories about the internationalization in small and medium sized firms and recent theories that entitle these firms as Born Global. Conclusion: Based on the existing theories and the qualitative data, we have concluded that the underlying factors for the Born Global firm?s internationalization are abilities and opportunities to create insidership in relevant networks. The most crucial underlying factors for Born Global firm?s internationalization are the ability to create processes to break old patterns of thoughts and the ability to ally with right partners. .

While the call for regulations against greenhouse gas emissions are louder then ever before, demand for oil is also at an all time high. Oil companies face the dilemma of making sound business without being perceived as environmental villains. In this essay I will examine how BP, one of the largest companies in the world, broke rank with the industry and devoted itself to being an environmental friendly oil company. The actions and motives of this change will be evaluated through up-to-date theories about company motivation to environmental adaptation. We see that BP:s transformation can be well explained through Simone Pulvers theory about the socially embedded company.
