Samband mellan tjockleken hos PVD-skikt och förslitningsbeteendet vid svarvning
This project has as main goal to study the influence of the coating thickness, deposited by arc-PVD- technology, on the wear resistance of coated cemented carbide inserts in three different turning operations. An additional effort has also been made to develop a new test method for evaluating flank wear resistance. Three different coating types (Coating A, Coating B and Coating C) have been studied in three distinctive thicknesses (2, 4 and 6 µm) for each type. For two of the coating types (Coating A and B) special studies has been done with the thickest coating, creating two additional coating versions of the thickest coating, by changing various deposition parameters, with the aim to enhance the cohesive properties of the coating and lower the residual stresses at the cutting edge. The results show increased crater wear resistance with increased coating thickness for all coating types, but the amount of increase changes with coating type (Coating A>B>C).
Människan i urskogen : vegetationshistoria i Hamra nationalpark under 2500 år
Pollen analysis of a peat core was used to reconstruct the last 2500 years of vegetation history, with focus on the impact of anthropogenic disturbance, in Hamra National Park, central Sweden. In addition, analysis of pollen in soil samples was performed in an attempt to locate ancient cultivation plots in the National Park.
The analysis of the peat core shows a development of the vegetation that can be divided into four stages of different degrees of human impact: A - virgin forest (c. 500 B.C.-A.D. 1300), B - grazed forest (c. A.D.
Tillämpning av GIS-analyser i MKB
The reason for performing an Environmental Impact Assessment (EIA) is to incorporate environmental concern in different kinds of plans and projects. The purpose of such an assessment is to identify and describe direct, indirect and cumulative environmental impacts.Geographical Information System (GIS) is a tool that can be used to combine spatial extension of both sensitive areas and different environmental impacts in a quick and easy way. Because of that, descriptions of environmental impacts and motivation of different standpoints on a specific issue can be more correct and easier to make if GIS is used as a tool.Hence, GIS can contribute to improve the quality of Environmental Impact Assessments. If the benefits of using GIS are to out weight the costs, geographical information of satisfactory detail, actuality and accuracy need to be available at reasonable prices.In this paper, case studies are carried out for three different geographical analyses to investigate the use of GIS as a tool in EIA. From these case studies, more general conclusions about the benefits and limitations of using GIS for Environmental Impact Assessments are also drawn.
Kommunikation med barn: Skapandet av en bilderbok : En litteraturundersökning om bilderboksriktlinjer samt tillverkning av en bilderbok
Many people believe that the analogue picture book is a dying media due to the increase of digital media. Contrary to popular belief, the publishing of children?s book in Sweden is continually increasing, which makes mapping the field quite significant. But to regulate the creation of a children?s picture book is problematic, because one does not want to impede the personal style of the writer or the illustrator of the children?s book.If the children?s book creator has an understanding of how to better communicate with children, the children?s book might have a grater impact on the child.
EU och folkomröstningarna En undersökning om de europeiska ländernas skiftande karaktär och hur dess väljare agerat i förhållande till detta
33 referendum has taken place in european states regarding the European Union since the fall of the Berlin wall. This thesis aims to initialy identify potential patterns in this group of referenda to launch and test a theory/hypothesis anchored in this pattern.The european states are differing in nature and the standard of living is chosen as the factor that can potentially have affected the outcome of the referenda held. The carrying thought here being that the voters in states with considerably lower standard of living than the european average would have a more positive attitude towards a deepened cooperation among european states.To try this connection between standard of living and how european citizens have placed their votes a main and principal quantitative test is undertaken. It is followed by discussion and arguments about the result of the test.The argumentation goes from being hopefull of the strenght of the hypothesis, to a more ciritical view of its' strength. The thesis is wrapped up in some argumentation about how and why it fails to explain what it was initially intended to do.

En Samhällsekonomiskt utvärdering av Uddevalla kommuns satsning på handelscentret Östra torp
There is an irregularity in the interregional migration in Sweden. An increasing proportion ofthe population is drawn to the metropolitan areas, which creates problems for the smallermunicipalities and towns when their population declines. At the same time, our whole societyis faced with a great challenge: we need to redirect towards a sustainable development, wherethe environmental issues are discussed and dealt with to secure that all present and futuregenerations are given equal opportunities to live a good life.The aim of this study is to, focusing mainly on the environmental dimension of thesustainability concept, examine the attractivity of housing with sustainability claims. Toanswer this, three research questions were used:? Was the migration motive to reduce their environmental impact a part of the decision tomove, among migrants who had moved to housing with sustainability claims?? If the motive was a part of the decision, how much impact did it have compared to othermigration motives?? Which factors in housing aiming at sustainability are considered important by peopleliving in housing with sustainability claims?The research questions have been answered using quantitative data, gained in the form of selfadministeredquestionnaires which were distributed in four different residential areas withsustainability claims in the county of Västra Götaland, Sweden.
Föräldraaktiv tredagarsinskolning och traditionell inskolning ? en undersökning.
Prostitution has been intensely debated in Sweden for nearly four decades. Two major investigations have so far been initiated by the government and numerous propositions have been put forward in the Swedish parliament resulting in the sexköpslag from 1999 that criminalizes purchase of sexual services. The law aims at punishing the buyer and protecting the women in prostitution, thus making it possible for women to be helped by various social interventions rather than punished. Swedish society has undergone major changes in these decades. Globalization, the internet and the membership in the EU have changed the Swedish society and influenced the discourse on prostitution.This paper has a twofold aim, on the one hand investigating if and how these changes have had an impact on the prostitution discourse in texts produced by the government and analyze how female and male sexuality in connection to prostitution is constructed.

Korrelationer mellan agility och unilateral och bilateral effektutveckling hos kvinnliga fotbollsspelare
Bakgrund: Unilateral benträning är ett relativt outforskat område inom träningsvetenskapen. Traditionellt genomförs fysträning för intermittenta idrotter bilateralt, trots att idrottens rörelser sker unilateralt. Det finns många studier som behandlar samband mellan agility och effektutveckling, men få som har undersökt skillnaden mellan unilateral och bilateral effektutveckling sett till agility.Syfte: Syftet med denna studie var att undersöka om unilateral effektutveckling har en starkare korrelation med agility än vad bilateral effektutveckling och agility har hos kvinnliga fotbollsspelare i division 2.Metod: Kvinnliga fotbollsspelare (n=13, ålder 23 ± 4 år) utförde vertikalhopp med tilläggsbelastning på båda benen, vänster ben och höger ben på 20 kg, 30 kg, 40 kg samt för båda benen på 50 kg och T-test och Pro agility test. Effektutveckling i förhållande till kroppsvikten på båda benen (PBbw), vänster ben (PVbw) och höger ben (PHbw) analyserades och korrelerades sedan mot T-test (Ttest) och Pro agility test (Proagility).Resultat: Signifikanta korrelationer hittades mellan agility och både vänster unilateral (PVbw-Ttest, r = -0,578) och bilateral (PBbw-Ttest, r = -0,741; PBbw-Proagility, r = -0,555) effektutveckling, där korrelationen bilateralt var starkast. Ingen signifikant korrelation hittades mellan höger ben och agility.Konklusion: Bilateral effektutveckling hade en starkare korrelation med agility än vad unilateral effektutveckling och agility hade hos kvinnliga fotbollsspelare i division 2..
Naturljud inomhus - En pilotstudie i tre fall
It's an everyday experience shared by many that nature can be of help in relieving pain, reducing stress, support mental recovery etc. In the last three decades or so this experience has also found support in a large number of scientific investigations. Among other things the experience of nature has been shown to reduce stress and pain in patients and to boost concentration and reduce impulsive behavior in children. Most of this research however has mainly been concerned with the visual modality. In this thesis the aim has been to focus on the auditory modality in this context by trying to reveal some effects on people from the exposure of nature sounds played indoors in three different environments: a grammar school class room, a kindergarten play room and a post-surgery wake up room at an intensive care unit.
Kundtillfredsställelse utifrån ett relationsperspektiv
Problem: The main problem this thesis brings up is what impact factors like trust, commitment, communication between a company and its costumers and value can have on costumer satisfaction on the basis of a relationship perspective.Purpose: The purpose with this thesis is to describe the importance of factors that can have an impact on customer satisfaction on the basis of a relationship perspective. To do this the author has looked into a company called Q-steps and conducted an investigation on their costumers opinion of their relationship with the company.Method: An interview was held with Q-steps CEO Sören Levén as the basis of the thesis, as well as a questionnaire that was sent to the company?s existing costumers over the web.Theory: In the thesis the author uses a model that describes factors that can have an impact on costumer satisfaction on the basis of a relationship perspective. This model is based on theories within relationship building in service companies.Conclusion: To be able to develop good relationships to their customers and as a result of this increase the level of costumer satisfaction, Q-steps has to take different variables into consideration. The main focus in this matter should lay on the variables that to a great extent affect the level of costumer satisfaction.
Pluralismens utmaningar - En teoriprövande studie med Belgien och Schweiz.
This thesis is set out as a testing of the crosscutting cleavages theory on twocontemporary cases. The aim is to test the explanation process of the crosscutting theory applied to the political and social situations in Belgium and Switzerland and furthermore to examine potential conflicts in pluralistic states. Our main questionis: How can the crosscutting cleavages theory explain the different outcomes ofsocial coexistence, even with the states numerous similarities? We have examined the two federal states through their social divisions of language, region, religion and socio-economy. Our findings show that both Belgium and Switzerland possess divisions in the above mentioned variables, which in most cases are cumulative structured.
Design av interaktionsmoment för spelarmotivation
The game industry is growing by every year but for some reason the research surrounding it hasn't caught up with its rapid expansion. This study aims at expanding the knowledge surrounding one of those areas, player motivations. An empirical model has been used to identify which interaction has the highest impact on player motivation in story-driven roleplaying-games. By conducting semi-structured interviews with eight different game developers using the GameFlow model to explore the use of interactions to sustain the motivation of the player a new criteria has been identified. This additional criteria was: Alive, and it was shown to have a high impact on motivation in story-driven roleplaying-games.
Det industriella byggandets betydelse för skapandet av de estetiska egenskaperna i bostadens arkitektur - En fallstudie på företaget JM AB
The study aims to investigate the impact of industrialised homebuilding in the creation of the aestheticproperties of the dwelling architecture.The concepts of industrialised homebuilding and the aesthetic properties of the dwelling architecture aredefined by previously developed models. In these models, industrialised homebuilding is described byeight characteristic areas. The aesthetic properties of the dwelling architecture are described by sevenaesthetic qualities.The study was conducted as a qualitative study, and in-depth interviews were conducted. The companyJM AB is the analysed unit that the author of this report has chosen to study. JM employees and by JMhiredarchitects were interviewed.The report concludes that characteristic area planning and control of processes are considered to havepositive impact on the aesthetic qualities if the process is designed in such a way that the creations ofthese are admitted.
