Kommunal självstyrelse - en myt? : En lokalhistorisk studie av Borgviks kommun 1861-1924
The hypothesis of this study is that the local government act in Sweden 1862 was an instrument for the state to keep its´ political influence on the local level. It did not open for local self-government. The swedish historians Dahlkvist and Strandberg description of the Swedish local government act support this hypothesis, as does the analysis of political scientists Pettersson and Söderlind. The general opinion that the local government act opened for local self-government does still exist among many swedish historians.This study had two aims. The first was to investigate the actual extent of self-government in Borgvik, a small municipality in Sweden during the period 1861-1924.
Standardisering av snöröjningsplan : Instruktioner, råd och tips för snöröjning av tak med stora spännvidder
The Swedish winters 2009/10 and 2010/11 were rich in snow and many roofs collapsed, mainly largespan frames. Investigations were made and the amount of snow was not the primary cause, insteadthere were several other causes. One of these was that in some cases roofs were shoveled in anunfavorable manner which affected the load patterns negatively, so causing the roofs to collapse.Most people lack the knowledge of how shoveling will affect the roof. Had there been an increasedunderstanding regarding shoveling, some roofs could have been prevented from collapsing.Through both qualitative and quantitative research in the form of interviews and calculations thetheoretically best ways to shovel a selection of roof types is presented in the report. The roofstructures covered are 3-compartment, continuous and Gerberspliced metal roof decks.
GROT-transport från norra till södra Sverige
The European Council agreed in 2008 on a climate and energy package to combat global warming. This package is valid for each EU member country and means that greenhouse gas emissions must fall by at least 20% and the EU's energy use to 20%, consisting of Renewable Energy in 2020. The Swedish Government has set stringent climate and energy with the intention to set an example for the rest of Europe. For example, renewable energy sources account for at least 50% of energy use and our climate emissions to fall by 40% by 2020. A combination of these goals and a steadily rising oil price has led to an increased demand for wood fuel in the form of such branches and tops.
Kvantifiering av osäkerheter i lyftkraftsmodellen
With today´s power uprates in BWR reactors the bundle lift force has become aproblem. The lift force is calculated using a best estimate approach and the resultfrom the calculation should pass the existing lift force margin. Lift force margin isdefined so that the lift force may not exceed 80 % of the fuel weight. The margin issupposed to cover all the uncertainties that exist in the lift force calculations.However, no uncertainty analysis has been conducted to quantify the uncertainties.In this report the uncertainties in the lift force model have been quantified. Each inputparameter to the lift force model which has been assumed to have an uncertainty isassigned a probability distribution.
Att synliggöra de osynliga : En analys om fyra kvinnliga irreguljära immigranter och om hur deras relationer till andra människor påverkar deras livssituation och identitet
The objective of this paper is to describe and analyze female irregular immigrants and their experience of how relationships with other people affect their lives and identity.A qualitative method is used in the study, because my main purpose is to analyse the respondents? lives and life experiences. The analysis is based on a symbolic interactionism perspective. The results are also analyzed based on previous research and the concepts underlying the paper; irregular immigrants, discrimination, power and identity.In summary, the respondents have a clear picture of how they live and experience their relationship to others and themselves and how this affects their lives and identity.Their experiences affect their lives and influence their behaviour and identity when they interact with others. Their own view of their situation means that they are afraid to seek care or report sexual abuse, threats or other similar conditions.
Den permanenta krisen : En narrativ studie om orsakerna till det första kriget mellan Ryssland och Tjetjenien
The aim of this study is to increase the understanding of the causes of the first war between Russia and Chechnya. Empirical data consists of four half-structured interviews with former Russian and Chechen war participants that tell about their perspective of the causes of the war between Russia and Chechnya. The study used narrative method and the theoretical framework consists of International Relations theories such as Realism, Geopolitics, Liberalism and Marxism. Geopolitics sees the geostrategic interest, territory as a cause of war. According to realism warfare occurs because of the state?s endeavor after power and influence in term of territory.
"Som politiker ska man vara noga med att inte lägga sig i"- Om politisk påverkan i socialt arbete
This study is about the perception of politics in social work. The aim of the study was to seehow people working with social work in municipalities describe their perception of how politicsaffect their work. The study was conducted in two municipalities in middle Sweden,which had a transfer of power in the 2006 election. Six people; two social workers, two executivedirectors and two politicians was interviewed about their perceptions about politics, ifthe ideological direction of the municipal matters, and how politics effect social work and theorganization. As analyze method organizational theory with focus on change and power wereused.
Undersökning av titanföreningar för tillverkning av standarder vid användning av röntgenfluorescens
SECO Tools manufactures tool inserts for all types of metal cutting machining. (Ti,W)C is a common raw material used in the production. At arrival, the material (Ti,W)C is always analyzed. Titanium has previously been analysed with x-ray fluorescence spectrometry, but as the calibration has previously been performed with two different types of titanium (rutile and metallic titanium), the results has differed. Because of that, this thesis project has been devoted to analyze titanium, to find the best titanium compound for producing standards.The work has been performed using literature studies and many experiments in the laboratories at SECO Tools inFagersta,Sweden.
Det regionala partnerskapet - ett verktyg för Skåne att samverka?
Because of a more globalised world the national states have been forced to make structural changes at both national, regional and local level to cope with different challenges. The regional community has become an important area which has resulted in a policy of more self governing, both for the regional and the local level.The aim of the thesis is to study the relation between regional and local level in the partnerships organisation. To fulfil the aim of the thesis, a case study of Region Skåne is used. The analyse is based on expressions such as cooperation, conflict, power and influence.The result of the thesis confirms that the opinion between the regional and the local level is very different. The representatives from Region Skåne experience the cooperation as quite good because it creates an opportunity for discussions and a possibility to learn from the other actors which in turn creates a qualification in the exchange of knowledge.
Strömkontroll till aktiva magnetlager med noggrann och störningsreducerad strömmätning
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).
Transient kallstartssimulering i GT-POWER
Etanol är ett intressant bränsle för framtida motorer där låga emissioner och bränsleförbrukning blir allt mer relevant. Etanol är både förnyelsebart och har intressanta förbränningsegenskaper med ett högt oktantal och snabb förbränning. Användning av förnyelsebara bränslen reducerar utsläppen av koldioxid samt medför att vi inte längre behöver förlita oss på de fossila oljedepåerna.En egenskap hos etanol är att bränslet kräver mycket värme för att förångas. Det medför att kallstarter blir ett problem då det är svårt att få bränslet att förångas och antändas då motorn är kall. Kallstartsförsök har gjorts på en direktinsprutad encylindrig motor med skiktad förbränning.
Vägen till framgång : En semiotisk analys av Tv3s representation av myten om det goda livet.
In the research field of the cultivation theory focus has shifted from TV in general to studying specific genres instead. It is proposed that there are similarities in otherwise different shows and that these shows give it´s voyeurs a solution to their problems. The purpose however of this study is to investigate how the myth about the good life is posed in Tv3´s supply. The theories used in this study are closely linked by their meaning. Narrative talks about the fact that texts, video in this case, contain stories. Ideology is the set of visions and beliefs one person has on the world and myth makes social, historic and cultural decided power orders in to facts.
