A change towards using more biofuels than fossil fuels is taking place in Sweden, and in many other parts of the world. This makes the use of fuel pellets increasingly popular, causing a greater demand for sawmill sawdust products. There is a trend towards the use of multiple types of shredders, instead of a single type in each sawmill. The purpose of the study was to characterize the different flows of saw particles that can be found at Sävar såg when cutting thick or thin wood with different cutting techniques. The saw particles size, shape, moisture content and heat value were analysed by the cutting stations: first cutting fast and slow, second cutting fast and slow, grading fast and slow and planning.

This thesis deals with query formulation in full text retrieval. The variables studied were query expansion and query structur[INS: e :INS , and the aim of the thesis is to study their co-effects on retrieval performance in a probabilistic system. The expansion was made with synonyms, and the structure by expressing facets and phrases. The study was performed using QPA, Query Performance Analyzer, which includes InQuery retrieval system and a sub-collection of TREC documents with its topics. The measurement used was precision at 11 DCV points.

The purpose of this study is to explore the factors affecting an individual's working life mobility and how this mobility is perceived by the individual. The study has a qualitative approach and the theoretical part is based on Castells', Giddens' and Bauman's theories of modern society and employment in relation to the individual. The study concludes that external circumstances in combination with internal driving forces are the reasons behind changing careers. The process is predominantly perceived as positive, especially education tends to strengthen self-identity. Work in general is regarded as important for a person's identity and new career changes are expected in the future..

The purpose of this master thesis is to investigate whether exhibitions and silent pedagogy can be used to develop more inspiring environments in the public library. Silent pedagogy is a term from the field of museum education describing the silent communication with visitors that takes place in exhibitions through introduction and orientation, layout and installation, as well as signage. In the 1980s, articles in a Swedish library magazine discussed the pedagogical importance of library exhibits and how they make the patrons aware of the library?s resources. This led us to museum education and a desire to investigate whether its theories were transferrable to the library context.

The Swedish energy system will be influenced by many future changes, such as energy and climate policy objectives. The installation of more renewable electricity could increase by using solar energy. Over the recent years, grid-connected photovoltaic (PV) systems have increased dramatically in Sweden, partly due to various support systems and compensation models. These support systems have been designed to make it easy for individuals and businesses to invest in self-generated electricity and thus contribute to the transformation of the energy system.The introduction of a higher proportion of solar energy may in turn affect the Swedish electricity system. This could mean that the electricity companies will be facing a number of changes in the near future.

Chlorinated solvents are common contaminants in soil and water. Under anaerobic conditions microbes are capable of transforming chlorinated solvents into ethylene which would result in a remediation of the contaminated area. In order to use natural attenuation as a remediation method evidence of continuous degradation is required. Furthermore, the degradation must occur at a sufficient rate and continuous monitoring of the site is needed until the demanded levels are achieved. A field study was performed on the basis of data from a dry-cleaning facility contaminated mainly by perchloroethylene.

This thesis investigates the overall risks of flooding over the Design Basis Flooding Level (DBFL) at the Swedish nuclear power plants (Oskarshamn, Ringhals and Forsmark), using statistical data and methods, but also considers historical events which might affect the overall risk of flooding at the specified sites.Considering the nuclear accident which happened in Fukushima in conjuction with the earthquake and tsunami which struck eastern Japan on 11 March 2011, operators and licensors of nuclear power plants all over the world conducted reviews and investigations on the overall risks posed to the plants from external events. One important such event is extreme water level.One part of the thesis includes an extreme value analysis (using Generalized Extreme Value distribution and Generalized Pareto distribution) of water level data from SMHI (Sweden's Meteorological and Hydrological Institute) measured at stations close to the Swedish nuclear power plants. The results of the statistical studies indicate that considering the return period used in the thesis (100 000 years), the water levels at the Swedish nuclear power plants are not expected to exceed DBFL.The other part of the thesis consists of a historical study of extreme weather-related events. The results of this study indicate that no historical events seem to have occured which would indicate a higher risk of flooding than the one suggested by the statistical study. .

The purpose of this thesis is to find out the reasons and perhaps some answers to the problem as we see it, the sickness benefit expiration of those who experience this. By this said we have also taken into account the different laws and adjustments in the long-term sickness benefit, but also major reformation of the security net in the Swedish society. The efficiency of the law on passive long-term sickness absence was added in July 2008, but was later in January 2010 supplemented. The purpose of this law wasn?t only to reduce the long-term sickness absence but also to reduce exclusion.

The purpose with this studie was to examine how individuals with experience of a long-term drugabuse describe their transformationprocess, and if this process has contributed to a change in their selfdescription. The studie was delimit to examine the transformationprocess, not in relation to what sort of abuse the informants had, or in relation to gender. The studie anwered questions concerning motivation to stop abusing, how the informants started the drugcareer, and how life as an abuser is described. In the studie qualitative method was used, five semi-structured interviewes were made with individuals who had a long-term addiction in the past. Symbolic Interactionism was the theoretical frame of referense that was used for analyse.

The purpose of this study has been to examine how female probation officers construct the concept of women who commit crime. This have been done by examining how the probation officers describe the phenomenon from their own point of view, how they perceive society's view of the phenomenon, how they describe the women's self-images and how their own perceptions affect the treatment of these women. To fulfill this aim the study is based on qualitative interviews with five female probation officers. We analyzed their statements by using Gender theory, Goffmans stigma term and Beckers deviant term. The result of this study shows that women who commit crime are described more as victims than offenders and that they are constructed as deviant in two ways; both in relation to the law but also in relation to their gender.

The purpose of this thesis is to examine whether parents that obtain long-term maintenance support in Enköping, consider the support as adequate when trying to meet their children's basic needs. The thesis also intends to investigate whether parents experience that their children, because they receive income support, have been socially excluded or stigmatized in their daily lives because of the family?s maintenance support. Further, the thesis aims to examine if there are any discrepancies in the above mentioned issue in relation to how long the parents have received maintenance support. Theoretical starting points used in this thesis mainly consist of the child perspective, social exclusion and the stigmatization theory.

The purpose of this study is to examine young adults', 18-19 years old, attitudes towards corporal punishment and with the help of social constructionism, grid-group theory and relevant concepts analyze the results and compare it with previous research. The research questions introduce various factors such as gender, origin and personal experiences of corporal punishment that may affect the attitudes. In order to fulfill the purpose and answer the research questions, a quantitative research method has been selected. There was 118 participants in the survey. The study was conducted by means of surveys in high schools in Örebro. Social constructionism made us realize how the community, perceptions and expectations might influence attitudes. Grid-group theory gave us an insight into how different family structures may explain why attitudes toward corporal punishment of children differ between individuals.

The aim of this essay was to investigate the effects of adopting a site to the UNESCOs World Heritage List. Thefocus laid on the example of the Decorated Farmhouses of Hälsingland, which was the most recent Swedishadoption. With the question of impact of the World Heritage List in mind, the region of Hälsingland became themain focus. The study was made with particular focus on Gästgivars, a farm located in the municipality ofBollnäs, to which the theory of social life of things was applied. The result of the World Heritage was, in the caseof Gästgivars, an increase of the cultural value and social status.This case study has shown that the impact of the nomination has not been immense, but suggests that longtermeffects can show.

This paper examines if European integration has had an impact on national political parties by looking at the stances of the Swedish Green Party and the Left Party on the issue of the European Community and the European Union over time. With the development of the European Community and the European Union, national political parties face the challenge of an emerging political arena. European integration research has recently become more involved with what is called europeanization and political integration within the member states them self, this paper aims to provide further leverage to the thesis that national political actors undergo some degree of europeanization and are politically integrated in the EU, by examining manifestos of two historically eurosceptic Swedish political parties. The theoretical framework provided by neo-functional integration theory as well as europeanization is used to examine the empirical material in order to see if the political parties at the focal point of this study can be said to have undergone a change in political policy regarding the EC and EU, both in quantity and content. The analysis show that indeed both parties has undergone a change and what might be considered a europeanization, considering that the presence of the EU as a political issue seem to have risen in prominence and importance in the examined manifestos.

This work is a GIS study of fishing rights distribution between different categories of ownersand properties in the Stockholm Archipelago. The purpose was to create basic data used toestablish fishing laws and restrictions within the Stockholm County.Stockholm?s archipelago consists of a unique environment and is the natural life andreproduction environment for ? of Sweden?s reproducing fish species. The increasingpressure from fishing, tourism and weekend population increases the need for an efficientfishing administration to prevent impoverishment and to ensure the biological diversity inSwedish fishing waters. There is an increasing need to review fishing administrationmethodologies, as well as studying the categories of ownership and properties located insensitive areas and areas influenced by physical disturbances in order to establish effectivelaws and restrictions.The Swedish fishing rights for an area are currently not connected to the ownership of theproperty to which it belongs.
