This thesis deals with numerical simulation of earth pressure against tubular bridges in the software Plaxis. Plaxis is a FEM (Finite Element Method) software based on numerical calculations for which approximate solutions are developed through an iterative process. The program is specifically designed for soil and rock mechanical tests, such as voltage and deformation calculations in soil.The Royal Institute of Technology conducted in 2005, field tests on tubular bridges of corrugated steel, which was part of Ersa Bayoglu Fleners PhD (Bayoglu Flener, 2009). She studied how two different tubular bridges deformed during installation and filling. Tests and measurements were made during filling.

People live longer. There is a growing need to increase the knowledge of aging and of the need among the elderly for medical care in the near future. As a step towards meeting this need, a survey among the elderly in Skåne is made by the division of Geriatric Medicine in Malmö University Hospital. This survey is called Gott åldrande i Skåne, GÅS. A frequent decease among the elderly is Mild Cognitive Impairment (MCI).

The aim of this study is to analyze how problems are represented within SOU 2008:27. Further more, the aim is to analyze how the new subject plan for history can bee seen as a product of this document. The method used, and the theoretical frame of the study, is based on Carol Lee Bacchi?s ?what´s the problem represented to be?? approach, which basic principle is that policies are filled with representations of problems and that these representations need to be examined. These problem representations are then themselves subject for scrutiny, the second step being an analysis of the texts presumptions and assumptions concerning view of man and perception of knowledge. The results show, among other things, that a problem representations can be found in the SOU; the school system is too vague and unclear.

This thesis has been carried out within the bachelor program for mechanical engineering at Karlstad University in collaboration with BAE Systems in Karlskoga. The purpose with this work was to design a mechanism and associated parts for loading and unloading of shots between primary and secondary magazine in BAE's new 40mm's ship gun.Parts designed or redesigned among other things a transfer mechanism for shot at loading and unloading, well as a hatch mechanism which makes the shots do not fall out of the primary magazine when making separate use. Various important details have been designed to maintain a good functionality of the mechanism.The construction work has mainly been carried out in the CAD software Solid Edge and its associated FEM module. The construction work has also been carried out on rough calculations for constructed details in order to ensure that they meet the stringent requirements of military use in tough marine environment. Two of the most critical parts of the structure where analyzed with the FEM module for estimating the stresses in the material at the applied load.The final design, which is a result of the thesis, meets the requirement specification and the set targets.

Previous research on philosophy for children in schools has almost exclusively focused on how it is perceived by students. The aim of this study is to focus on how it is perceived by five teachers and other adults involved in implementing philosophy for children in schools, in total four teachers participated and one adult who worked with implementing took part in the study. The theoretical background is composed of Olga Dysthes view that knowledge is not only constructed but that the object that one intends to gain knowledge of has to be interacted with and how she applies this view dialogues in the classroom. The study was conducted by interviewing the participants. The results found that the teachers saw philosophy for children as something more than a tool to work with questions that were important to students, they were also viewed as a way to work with language and building solidarity within the class.

Purpose:The purpose of this study is to describe and explain the international music company reports of its intangible assets to examine whether similar methods can be applied to the Swedish market.Method:The study was based on a qualitative and abductive research approach. Collected data is mainly from secondary sources in the form of auditor approved consolidated financial statements.Conclusion:The Swedish music companies activate their intangible assets only partially or not at all, despite the fact that assets in the form of music catalogs, rights, contracts and advances are those that generate revenue for the companies. The study has resulted in a description of how the companies are doing on an international level with the IASB and FASB's regulation. With this report, we have found flaws in the way the Swedish companies prepare their accounts according to the current regulations. In the analysis, these shortcomings are highlighted and to what extent these international standards can be applied in the Swedish companies to take a step towards a more accurate picture and a harmonized and comparable accounting..

At Forsmarks Kraftgrupp AB (FKA) forces on pipe systems due to transient flow are frequently calculated as a step to verify their structural integrity. In nuclear industries these forces are often calculated with a one dimensional thermal-hydraulic analysis-code called RELAP5. When calculations regarding more complex geometries are needed, the three dimensional code Fluent is often used. This code is highly time consuming and requires large computational power.This projects aim is to compare calculations of pressure, flow and forces carried out by RELAP5 and Fluent for an arbitrary pipe section during transient flow conditions. This has been accomplished by constructing a simple geometry for which a transient flow is simulated in both programs.

The preschool should lay the foundations for lifelong learning in a good educational activity. Preschool curriculum is designed to enhance the quality of the educational activities. To translate the curriculum in business, the importance of early childhood special education knowledge. With regard to the completion of theoretical knowledge requires the ability to translate theory into real action. Professionalism is essential to anchor the curriculum in daily operations.The study's purpose was to investigate preschool teachers' perception of professionalism and how the implementation of the preschool curriculum in their daily business functions.The study was an interview with four pre-school professionals with the spread in age and experience.

With growing economies and better living standards in many parts of the world today, there is a need of expanding the capacity of generating electricity. The alternatives for renewable energy technologies are not fully developed and have still some problems to conquer.The company Minesto has developed a technology that is called Deep Green. It is designed to gain electricity from tidal currents. Deep Green works in a similar way as a kite that is attached to the seafloor with a moving wire. It contains of a wing that moves due to the water current.

There is always a need for more effective ways to store energy in order to reduce the human impact on the environment. One step on the way can be the use of flywheels as kinetic energy storage devices. Low frictional losses are essential for a flywheel to be effective. To minimize these losses active magnetic bearings (AMB) can be used to keep the shaft centered instead of the more conventional ball-bearings. AMBs use actuators and a fast control system that needs correct and noise-free measurement data of the shaft position and the current in the actuators to work properly.This thesis explains the process of constructing power electronics and a current measurement system for active magnetic bearings (AMB).

Bovine Respiratory Syncytial Virus (BRSV) is a common cause of respiratory disease among young cattle. The virus causes severe losses; the herd mortality rate can sometimes be as high as 20 %. In this study the avidity (i.e the antigen binding force) of BRSV specific antibodies was measured to see if there was a difference between antibodies produced during an acute phase of infection and antibodies produced by earlier infected animals. A commercially available ELISA-testkit against BRSV-specific antibodies was used and an incubation step with 6M urea was added. The effect of the urea is that it breaks the weak bonds between antibodies and antigen while the stronger bonds remain intact. Four different groups of animals were included in this study; seven calves that were naturally infected, three acutely infected calves with known time of infection, five cows that were seropositive during several years and four experimentally infected calves that had been a part of a vaccine trial. The results of this study showed that antibodies produced during the acute phase of an infection had a low avidity and that the avidity increased with time after infection.

AbstractTo take the role of another is an important and a central part of human interaction. When we take the role of another we not only learn about them but also we learn about ourselves and how we interact with other people.  Social work in this form, working with directly with families in crises, is much about understanding other people?s perspective and feelings. It is important to know the strategy of one?s work and which perspective to work from.

The main purpose of this essay is to investigate the legal position for employers concerning protection against what employees can express about one?s employer in social media.It may regard dissatisfaction concerning employment, tort or so-called whistleblowing. The spread through social media may be comprehensive and thus cause more damage to the employer.Employees within the public sector as well as in the private are protected by the liberty of speech, which is constitutional, even the protection of sources or the right to criticize can offer some protection. This gives the employees the possibility to widely express themselves in private social media as long as it can?t be classified as a violation, which per se is very rare.However, certain differences between the both sectors will be pointed out.There are still no constitutional rights regarding social media, but a grey area has emerged concerning the legal position.

When planning new wind farms, the cost for the internal electrical grid is estimated to account for 8-9 % of the total investment cost. On top of that, the cost for accumulated reduced income over several years (due to electrical losses), has to be added. The economic lifespan is relatively long (about 20 years) which means that an error in the loss calculation could lead to a bad decision basis. The accumulated reduced incomes due to electrical losses can be higher than the initial investment cost for the internal electrical grid.Today, Statkraft Sweden is using a template number when estimating the electrical losses in a wind farm. The actual losses are probably lower than the template number which could lead to an unnecessary high loss cost when planning a new wind farm.The aim of this M.Sc.
