The Göta älv-bridge is a welded steelbridge which is located in Gothenburg,it connects the inner city of Gothenburgwith the island Hisingen. Cracks wasdiscovered in the steel in 1999-2000which started an investigation of thebridge to clearify the condition of thebridge. The conclusion was a monitoringsystem based on laser light sent throughan optical fiber.This report describes the bridge, thedamages, the monitoring system and thetraffic on the bridge.Stefan Pup, at Vectura Borlänge was mysupervisor during this work. In myinvestigation the costs of themonitoring system and the costs ofclosing the bridge is compared andevaluated. The biggest investigatingpart is the costs of closing the bridge.The results of my investigations is thatclosing the Göta älv-bridge would cost 1107 300 SEK / day.

The project has been provided by Zenit design group and the goal for this project was tomanufacture and perform tests of a prototype that supersaturates water in a continuous flow ofwater. The project has involved finding and sorting out relevant data in scientific papers, books,communication with foreign manufactures and other platforms for information.The project has resulted in manufacturing of a test rig and an oxygen infuser based onmembrane technology. The test rigs purpose was to perform tests on oxygen infusers fordifferent Comparison test and performance benchmarks in a in a laboratory provided by Zenit.The project led to satisfying results using the oxygen infuser manufactured by the authors withcomparable levels of saturation to the reference infuser.The theory behind this project is based on medical research, belonging terms will be explainedbut the authors have chosen to delimit the project from the medical area. The reason for this islack of knowledge in this area and its irrelevance to the mechanical engineering education insuch..

Currently, the whole globe is faced with serious problems which negatively affect people around the world: increased pollution, excessive waste, and weather pattern changes. ?Left? and ?right? wing political parties alike have embraced ?green? politics and for many of these parties, environmental issues have become a top priority that is very much reflected in their manifestos. This study examines the environmental goals of two of Sweden?s largest political parties and how these ambitions are reflected at a local level.

Med min bakgrund som blivande geografi och idrottslärare har jag valt att undersöka rökning på två olika skolor med skilda socioekonomiska och geografiska förhållanden. Syftet med detta examensarbete var att undersöka vad det fanns för lagar, regler och direktiv för skolan gällande ungdomsrökning. Syftet var också att belysa skolornas förhållning till rökning skiljer sig åt och om det har någon koppling till vilket område de befinner sig i. Detta har undersökts dels genom den svenska skolans olika styrdokument, dels genom en enkätundersökning till rektorerna på två olika skolor. Undersökningen visade att det fanns tydliga skillnader i vilken vilket förhållningssätt dessa skolor hade till ungdomsrökning.

The present study examines the effect of a nine-hour Acceptance and Commitment Training (ACT) intervention for teachers who experience stress. Twenty-two teachers from four different counties in southern Sweden were randomly allocated to an ACT intervention (n=15) and a control group (n=7). The ACT condition received three three-hour sessions of ACT over a six-week period, and the control group received a three-hour stress lecture at one occasion. At a follow-up four-weeks after completed intervention, ACT participants showed significant in-group differences on stress, psychological flexibility, general health, and burnout. At a between group Comparison, only psychological flexibility was significantly enhanced at the follow-up.

Eutrophication of the Baltic Sea and Swedish lakes remains a major problem despite many years of effort to reduce the emissions of nutrients. One major source is waste water systems, especially private sewage systems. These sewages accounts for a very large share of nutrients per capita in Comparison with citizens connected to larger sewage treatment plants. Norrtälje community has the greatest number of private sewage systems in Sweden. Discharges of nutrients, especially phosphorus, to the Baltic Sea from these sewage systems are significant.

Fluids are important to the Visual Effects Industry but extremely hard to control and simulate because of the complexity of the governing equations. Fluid solvers can be divided into two categories, those of the Eulerian point of reference and those of the Lagrangian. Both categories have different advantages and weaknesses and hybrid methods are popular. This thesis examines Smoothed Particle Hydrodynamics, a Lagrangian method for physically based uid simulations. To allow the artist the exibility given by shorter simulation times and increased number of iterations, the performance of the solver is key.

This study was conducted to test the hypotheses that a forest managed by selective cutting can store more carbon than a forest managed by clearcutting. The study was carried out as a meta-analysis. The data that was found was analyzed by performing t-tests on the proportional effect that the two silvicultural methods had on the driving factors of CO2-efflux and carbon stores in coniferous boreal forest. In all areas tested, an effect in favor of selective cutting was found, but not all of them significant however. The soil respiration following selective cutting was significantly lower than that of clearcutting, and the primary production of a clearcut area cannot according to reason exceed that of an area post-selective cutting.

In three areas in the province of Småland studies has been done to investigate how big damage the moose may do to P. abies. An inquiry examination and two different types of surveys were done to find out how big area, which volume and which financial consequences the moose debarking has had on the forest. When the volume was calculated the rot spreading was included. The area that was damaged was stipulated with the answers from the inquiry examination. 59 % of the asked forest owners answered the inquiry.

The purpose of this essay was to study what students at the upper secondary levels thought that they learned in physical education and if there were differences between girls and boys learning. The purpose was also to study different factors that could affect the learning and to show how curriculum and prior research relate to the students learning. In this essay we used the three aspects of health that are mentioned in the description of physical education: the physical, the social and the psychic. The study was based on a quantitative research where 165 students answered questionnaires about their learning. Our research showed that the students did not get the knowledge that the A-course in physical education should provide and that the goals for the course were not accomplished.

Purpose: The purpose with this empirical study is to investigate how many companies have chosen to apply the K2 framework and see why the remaining companies have chosen not to.Methodology: A choice of a quantitative approach has been applied to collect information and create a foundation for the problem. Furthermore a qualitative approach has been selected to cover the remains.Theoretical perspective: This section contains a presentation of the agency theory, the institutional theory, the k-project and a Comparison of K2 and the existing regulation.Results: Three out of 143 companies applies BFNAR 2008:1. 13 out of 143 companies use self-generated intangible fixed assets. Out of 29 contacted companies only three know about K2. The 29 companies are from various lines of business within an area.Conclusion: The conclusion of our research is that the majority of the companies did not reject to use the K2 regulations.

The aim of this thesis is to explore how a bookstore chain and a public library meet the needs of their customers through environmental scanning. The empirical material is derived from six semi-structured interviews with six informants, three from each organization, together with an analysis of internal documents. The method used is a case study and the theoretical framework is based on models used in the process of environmental scanning, as described by Choo, Hamrefors and Hedin & Sandström among others, and which facilitate a Comparison of the environmental scanning of the two organizations. The results of the study indicate that the library, as a public organization with a mission in society, perceives the environment as society as a whole and all its members as their users, whereas the bookstore concentrates on the sectors of the environment that affect their sales. The consequences of these different views are that the library is more active in the environment and uses surveys as a basic source of information, while the bookstore is more passive, and relies on statistics for information.

The aim of this study is to analyze Hinduism in upper secondary school textbooks using a gender-based perspective. The specific material used consists of four textbooks, whereof two are published prior to the curriculum Lgy 11 and two are published after Lgy 11. In order to analyze the textbooks the following methods are used: content analysis, picture analysis and comparative analysis. First, the contents and pictures of the textbooks are analyzed using theories on gender. After this analysis the results are compared to the relevant curriculum and its guidelines for the analyzed subject.

The purpose of this study is to find out teachers view on manipulatives as a way to concretize a certain mathematical content and to highlight knowledge and experiences within the range of using manipulatives to concretize. By answering the questions below different approaches a teacher may have towards the manipulatives and how that may impact on student?s learning will also be discussed in Comparison to mainly traditional and socially constructive theories of learning.What is the teachers view on manipulatives as a way to concretize?What purpose do they have when using manipulatives?According to the teachers, what does it mean to concretize a certain mathematical content?According to the teachers, what connection is there between manipulatives and concretizing?Through interviews and observations conclusions can be made that the teachers are in general positive towards using manipulatives as a way to concretize a certain mathematical content although the definition of what a manipulative is differ somewhat between the teachers. The teachers working with manipulatives do it in a well thought out fashion but more research is needed to furthermore define the purpose of using manipulatives. Few countries spend so much time concretizing and working with manipulatives as Sweden do, but still Sweden score below the OECD-average on the mathematical PISA-tests.

The aim of this paper is to look into the occurrence of home schooling by choice in Sweden. It examines the subject of home education in order to provide an informative overview. It also looks into the legal aspects of the matter to see whether freedom of choice is an issue here when it comes to choosing a certain type of teaching for children of compulsory school age. A further purpose is to provide a Comparison of home education in Sweden and in other countries such as the United States, England and Norway.In order to do this we have carried out a secondary analysis of previous research and have also interviewed teachers as well as people with experience of home educating their own children. To accomplish this, we had to look to England for literature and home educating families as home education is a much more common practise in England.The result of this paper strongly indicates that home schooling is not only a legally viable option to traditional schooling, both in Sweden and the other countries concerned, but that it is also a trend that is expected to increase.
