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.

AbstractWe are interested in group meetings of the self-help group Alcoholic Anonymous and the emotional energy created therein. We examine which impact self-help group AA has on its group participants regarding: group meetings, dealing with alcoholism and identity. Group membership has great value for individuals; it provides social identity and possibility to self-value. Previous research shows that group members of self-help groups who have been sober for a period of time experience higher self-esteem and less anxiety compared to non-members. Our thesis is based on a hermeneutic approach.

Title: Overreaction on the Swedish stock market Seminar date:2008-01-30 Course:Nek K01- Bachelor Thesis in Economics (15 ETCS) Authors: Advisor:Oskar Herbe and Ludvig Persson Hossein Asgharian Key Words:Overreaction, Anomalies, Market Efficiency, Contrarian investment strategies Purpose:The purpose of this thesis is to test if the overreaction hypothesis as originally described by De Bondt and Thaler is a good explanation model for the Swedish stock market. Further, our intension is to divide the stock market into three segments by company size, in terms of market capitalization, to control for size effects. Method:We have conducted this study by analyzing Swedish stock data in the period of 1989-2007. Within this time span, using overlapping formation periods, we have constructed two types of portfolios, winner portfolios and looser portfolios. The portfolios represent the 30 per cent best performing respectively worst performing stocks in terms of returns.

This Master´s thesis aims to aquire knowledge about volunteers attitude toward work. It emphasis is on the differences between volunteers and non volunteers. There are four research questions used in order to fulfill the aim in a scientific manner. The essay aims to get in depth knowledge regarding whether or not the respondents feel that they have gained advantages in work life due to the fact that they are involved in volunteer work. One of the pivotal questions is if there is a possibility to see a pattern that binds together the reasons for volunteer work and the attitude toward work.

International Contract Law presently offers three sets of principles: the UNIDROIT Principles of International Commercial Contracts (the UNIDROIT Principles), the Principles of European Contract Law (the PECL) and the Draft Common Frame of Reference (the DCFR). These sets of principles contain general principles which are intended to serve as model rules. The three sets of principles have been published, but they have not been adopted. The UNIDROIT Principles and the PECL are not meant to be adopted either. There are different opinions as to whether the sets of principles can be considered to be a source of legal status at all.The sets of principles have been referred to in Swedish law.

A storm in January 2005 felled 75 millions cubic metres of forest in South Sweden. Previous studies of wind damage in thinned stands indicated the importance of early thinnings. The risks of wind throw increased by increasing age and height of the stands. Previous studies also indicated increasing risk of wind throw along the strip roads. The aim of the present study was to investigate wind damage in Norway spruce stands in South Sweden in relation to time of the first thinning and different pattern of strip roads (width, length and direction).

Abstract.In Sweden today, a collaboration was formed between the Swedish Sport Confederation andthe Swedish upper secondary school education. While this process was taking place, theSwedish Sport Confederation also tried to collaborate with the Swedish Academy. However,at the time the Academy did not have any involvement with the former.The purpose of the study was to research when and how the Swedish Sport Confederationcreated a collaboration with the Swedish Education Systems both on a National and Locallevel. I have also done a research on both the Knowledge Society and Elite sport talents tofind out if Elite sport will be affected in any way because of the existence of Knowledge Society,and also the reactions of the sports talents if any. My final pursuit was also to find out ifthe Knowledge Society can bring about a quick change to this silent conflict between theSwedish Sport Confederation and the Swedish Academy.For my study, I have used two different theories.

The aim of this master's thesis is to study what attitude public libraries in Sweden show towards video games. By using critical discourse analysis as both theory and method we analyse several texts emerging from a debate mainly discussed in blogs. Main topics in the debate are video games in the library, the purpose of the public library and Library 2.0. Our analysis focus on views expressed concerning the work and purpose of the public library, the librarian and the library user - and to identify the main visible discourses in the discussion.Our findings consist of two discourses representing two different views in the debate. We call these two discourses the general educational discourse and the interactive discourse.

There are several methods and models within the areas of software engineering on how to proceed during a software development process. For each of these methods and models there are benefits and drawbacks, depending on how you choose to look at them. A difference of principle between the different models is that they either advocate iterative development or not. In parts of software engineering one makes use of different methods depending on which is most fitting in a specific situation. There are several methods on how to recieve more qualitative data from the end-users during the requirement collection, but the reappearing pattern is still user centric participation, which means that the user participates more actively in part of or the entire development process.

Designmönster är beprövade och återanvändbara designlösningar på återkommande designproblem inom en viss kontext. Designmönster handlar om att inte behöva uppfinna hjulet om och om igen. Designmönster fångar lösningar och kunskap inom mjukvaruutveckling.Vi har försökt beskriva och förstå hur IFS och Intentia tar sig an arbetet som omfattas i våra frågeställningar. Våra frågeställningar har varit hur designmönster kan hittas, dokumenterasoch katalogiseras samt hur designmönster kan spridas till medarbetare.Vi har i denna undersökning anslutit oss till de tankegångar som finns inom hermeneutiken och vi har därför valt att använda oss av en kvalitativ metodteori, vars drag ligger mer åt dethermeneutiska perspektivet. Vi har genomfört intervjuer med representanter från ovan nämnda företag.Undersökningen har visat att bägge företagen har grupper med erfarna utvecklare som finner nya designmönster.

The aim of this study is to describe a number of type stands of lodge pole pine in Norrbotten with respect on stem volume and total biomass. Further questions to answer is if there is stand characteristics that make the stands more suitable for pulpwood in early thinning, or if it is better to apply whole tree harvest. The study shall also give an indication if bio energy can be an economical interesting alternative for Sveaskog. Sampled trees represented the variation in the different stands. Five trees were selected from each stand to represent that stand. Stem volume and biomass (kg dry weight (DW) per hectare) for each fraction was calculated.

The classic view of trout (Salmo trutta) life history is that trout begins its life in freshwater, migrates to the ocean after about 1-4 years and then returns to freshwater to spawn. As trout fry have been caught at the mouth of the River Emån, near the Baltic Sea, researchers have speculated that some trout emigrate during their first year of life. The purpose of this study was to describe the variation in the length of time trout reside in freshwater before they migrate to the ocean for the first time. Another purpose was to investigate whether it was possible to discern where and how long the fish spent in freshwater and saltwater during different parts of their lives. Between 2007 and 2009, 23 adult trout were captured in the River Emån in southeastern Sweden.

The spontaneous blink rate is found to be a non-invasive but functional, reliable and useful way to monitor central dopaminergic activity. Dopamine is associated with a range of functions such as reward, motivation and learning. It plays an important role in goal-directed behavior and in maintaining a behavior once a task is learned. As far as the author knows, there are today no publications that discuss the topic regarding the possible link between training and spontaneous blink rate in dogs. Therefore, eight privately owned dogs were included in this study to determine if there was a significant difference in the spontaneous blink rate before and after the process of learning a task.

In this textual analysis I have examined the book Att följa Jesus by Ulf Ekman and information from Word of Life's official website. The aim of this study is to see how a religious leader is shaping the identity of the groups members after a certain pattern that differs from the surrounding, secular society. The research focus  of this essay includes several aspects:  how a culture is formed in a religious minority in contrast to the prevailing cultural context; how the material can be explained by Paul Pruyser?s theory on the psychological worlds; how what Ulf Ekman writes about distinguishing themselves from the environment differs from how other religious minority groups distinguish their identity;  and,  how the psychological world, expected behavior, and context of Word of Life can be structured by Valerie DeMarinis? model of assessment. I have placed Word of Life in a realistic illusionistic world developed from Paul Pruyser?s theory of psychological worlds.

Mast cells have for a long time been known to accumulate around tumors (Maltby et al., 2009). Studies show that they may be important and sometimes essential in tumor angiogenesis, tumor growth and metastasis of tumors (Soucek, et al., 2007; Xiang et al., 2010). In an expression array study (Wensman et al, submitted manuscript) performed on mouse mast cells exposed to tumor conditioned medium, the gene 4-1BB was among the most up-regulated genes compared to control medium. 4-1BB codes for a membrane receptor protein of the tumor necrosis factor superfamily and has been shown to be important in T cell regulation in tumor diseases. This study was performed to investigate if human mast cells up-regulate 4-1BB when they get exposed to tumor conditioned medium.
