This thesis work is made by Torbjörn Johansson on Karlstad University for Uddeholms AB. The assignment in this thesis work was to investigate tough cutting in three different tool steels: Vanadis 4 Extra, Vancron 40 and Sverker 21. The research was to compare the wear of the tool after cutting in each one of the tool steel alloys. The research was also made to see if the tool cutting in Vancron 40 has a better wear than the tool cutting in Vanadis 4 Extra and also compare the results with Sverker 21. All three of these alloys are a part of Uddeholms AB:s range of products, and is used in applications like forming tools and knife tools. Vancron 40 is a powder steel with a very good combination of mechanical properties like ductility, adhesive strength and hardness.

Train travel has increased in Sweden, and future increase of train transports putdemands on the already vastly exploited railroad net. The increased need of capacitycan be seen in the ongoing and planned expansions of the railway track. One part ofthe railroad infrastructure which is affected by an increase of travellers is the design ofthe station platform. Since the platform is the place where the traveller meets thetrain, dangerous situations can occur in this environment. A number of studies focuson single safety risks, albeit there is no research to show the full picture of safety inthe platform environment.This study aims to treat and put together a compilation of risks for the traveller in theplatform environment in the form of a checklist, which can be used as support inplanning and design of a safer platform environment for existing or planned platforms.The thesis has, through case studies of five ongoing projects within the NationalRailroad Administration (Banverket), interviews with train company personnel andinternational railroad administrators, identified and treated safety (and security) risksin the platform environment.The conclusion of the study is that the relations between the traveller, the physicalplatform environment and the project organisation are important to explore andexploit when designing effective safety measures.

The efficacy of screening for breast cancer with mammography has been a subject of controversy during the last decades. However, the general opinion is now that screening reduces mortality in breast cancer (Zackrisson, 2006). It is nevertheless important to weigh the efficacy against the harm and costs associated with screening. Cost-utility and cost-effectiveness analysis of screening have generally failed to incorporate side effects such as anxiety and discomfort related to screening tests and the following diagnostic tests (Gyrd-Hansen, 2000). This study seeks to include such side effects in a cost-utility analysis.

The society is developing fast and the development is constantly on-going, new technology results in new opportunities and new problems for both companies and consumers. The use of Internet has heavily increased around the world; this means that the companies can use Internet as a channel of communication to reach the consumers. The most recent type of marketing is web marketing. The fact that web marketing is constantly changing raise the question of how effective different types of web marketing are.The purpose of this study is to investigate four selected types of web marketing. This is achieved by comparing the response from the consumers and the cost for the different types of web marketing.

This final thesis aim to create a support that can decrease the uncertainty when planning the cable drum flanges lines that produces cable drums in the interval 100 to 320cm in diameter at Vida Packaging in Hestra. The purpose attains through finding an optimal batch size that minimizes the total storage cost and order prime cost, without degenerate delivery capacity to the customer.

Alkohol är en del av vardagen för många svenskar idag. När denna konsumtion övergår till ett missbruk uppstår det problem för individen och för samhället som stort. I denna studie har författarna genomfört en Cost of Illness studie för att beräkna samhällskostnaderna för alkoholmissbruket inom Hammarö kommun.Resultatet visar att kostnaden för samhället som helhet, för detta missbruk uppgår till 29 434 297 SEK, år 2013. Den största kostnadsbäraren är staten med sina 15 967 819 SEK av den totala kostnaden. Kommunen står för 10 230 270 SEK av den totala kostnaden.

It is of increasing importance to in the most effective possible way, manage and control all the transactions of raw materials, products and information that are exchanged between an organization and all its operators. These flows and the need for strategy and managing the processes of planning, implementing and control of the supply chain, has given name to the concept supply chain management. Supply chain management involves all movement and storage of raw material, and all the processes that is needed to manufacture a product from origin to consumption. Globalization, technology and increasing time and quality-based competition are all driving forces behind the concept and reasons for an increasing interest in supply chain management.The purpose of this essay is to by using a qualitative case study examine which decisive success factors that can be identified for effective supply chain management. We have compiled different theories on the subject to use for analyzing a case study Li & Fung, who is a successful supply chain management company.

The purpose of this essay was to examine how youths are described in certain written statements that are produced by the social services. The statements that this study has focused on, are those written with the purpose of serving the court with suggestions of treatment-measures when a person between 15 and 18 is suspected of having committed a crime. The main issues were: How is the content in these statements described and what do these descriptions tell the reader? Do the images of youths in the statements differ, depending on the degree of intervention for the suggested treatment-measure? The essay is based on a qualitative content-analysis of 50 statements and the material has been analysed from a social-constructive theoretical perspective.The study shows that the youths in the statements are described through descriptions that reinforces a positive or a negative image of the youth, and that these descriptions are described as either utterances or facts. Depending on the degree of intervention for the suggested treatment-measures, the information in the statements differ in that descriptions that are likely to reinforce a positive image of the youth are more frequent in the statements where no or less intervening treatment-measures is suggested.

In Sweden, prostitution is politically defined as a social problem, more precisely, as a form of male violence against women. The definition is distinctly manifested in the government bill Kvinnofrid, characterised by the unique Swedish law that prohibits the purchase of sexual services.This thesis examines how the Swedish solutions of prostitution are carried out. By interviewing central actors working with prostitution in different ways we aim to answer the question: What measures are taken to decrease prostitution and what implications does the Swedish solution have?The analysis is divided into two parts. First, we analyse the concrete measures taken against prostitution ? what is done, how, and why? Second, we analyse the complexity of prostitution measures by applying complementary analytical perspectives: the symbolic and the discourse perspective.The study shows that measures taken to decrease prostitution vary and depend on individual actors? understandings of the political definition.

The aim of the study was to examine if and how the social service and the social welfare secretary provides against threat and violence in the encounter with clients. The study is qualitative and carried out with six semi-structured interviews with social welfare secretaries and participation observations at the social welfare offices in three municipalities. The theoretical starting points used were symbolic interactionism and strange loops. The result shows that social service and social welfare secretaries both use measures to prevent threat and violence to occur. The precautionary measures mainly used by social services are ; looked doors, alarm device, loose objects removes and interview rooms are furnish in purpose for the social welfare secretary to flee the room at urgent need.

This thesis lays the foundation of the future routines of effective error repotring fortraffic devices in the raiway sector.If a device, for example a timetable display, stops working it is vital that the device isfixed as fast as possible so that the travelers dont miss any important information.The methods that are used today are old and not very effective. It can take time forthe repairmen to find the right device or locating the broken component. At the sametime he is supposed to maintain telephone contact with central control throughoutthe whole session.The need for a new, more effective, system is vital to make the whole repair pfocessmore effective and let the repairmen work without having to contact the centralcontrol by phone.I started this work by examining the possibilities of assigning every object with aunique identifier (ID tag) that could be accessed by a manual scan device. The ideawas that the ID tag could holw information about the object and be obtained byscanning the ID and get the information presented on a mobile device.The work also included building a internet application that enabled the reader to seeand change the information on the ID tag.The result was a database that stored information of different objects which could beobtained by scanning the ID tag and presented by a internet application..

This thesis explores some issues regarding estimations of the cost of capital on the Stockholm Stock Exchange through reverse engineering of the Residual Income Valuation model and through usage of the Capital Asset Pricing Model. Previous studies are in conflict of whether the risk premium changes considerably over time or not. Furthermore, the risk premium estimated by CAPM tends to be fairly stable. In this study, reverse engineering of the cost of capital implied by analysts? forecasts shows a significant difference in the risk premium over time.
