The aim of this master thesis was to create a dynamic model for the processes in a solid fuel boiler of the moving grate type. Another aim with the model was to keep it as simple as possible but still able to catch the dynamics of the processes in the bedplate of the boiler. The creation of the model had its origin from drying and combustion equations used in earlier modeling work of boilers. The represented model has been used to simulate different kinds of disturbances in a boiler and different ways to control the boiler. These tests show that controlling a number of parameters in the bed of the boiler is an effective way to keep the grate stable during disturbances.

This report aims to provide an insight into the particle physics of today, and into the research that goes on within the field. The focus is partly on the recent discovery of the Higgs boson, and partly on how software can be used to simulate processes in particle accelerators. Basic concepts of particle physics and the search for the Higgs boson are discussed, and experimental results, including those from the Large Hadron Collider, are compared with simulations made in MadGraph 5. Furthermore, simple new models of particle physics are created in FeynRules, in order to make simulations based on the models. To support the presentations of these aspects, some of the underlying theory is built from the ground up.

Hammarby Sjöstad is a new district of southern Stockholm built with focus on reduced environmental impact by recirculation of materials and sustainability. The environmental goals aim to cut the water consumption by half and a separate storm water treatment. Thus, the wastewater will be more concentrated and will originate from the households only. The Sjöstad project includes the idea of a local treatment plant for the household wastewater. To evaluate this possibility, Sjöstadsverket, an experimental treatment plant was constructed.

With the farming methods of the past century the agricultural landscape has changed. This has led to the fact that many habitats and species have been significantly reduced. Sweden is committed to the preservation of biodiversity through various conventions and laws. In the EU's Common Agricultural Policy there are currently agro-environmental schemes, which were created as an instrument for reducing the negative impacts of agriculture on nature and environment. Within this system any farmer who perform environmental measures are financially compensated for this.

The purpose of this thesis is to shed light on a present trend of professionalization in Swedish local environmental politics, which have recently seen a decline in active participation of the citizens in favor of an increased governmental regulation. With the aim to closer investigate this relatively new phenomenon, the paper is a qualitative single case-study of environmental policies in the Swedish municipality of Karlskrona. In this case, the municipality is obviously balancing between regarding the interests of the national level and the interests of its own citizens at the same time. This motivates the use of system-theory, and relates to the classical political paradox between participation and efficiency which is also a present theme in the paper.This text-analysis based on interviews with personnel and documents from the municipality shows a visible trend of professionalization in the local politics of the municipality of Karlskrona, from a large grade of participation and a strong bottom-up approach in the days of Agenda 21 to now being more strongly top-down defined by national environmental objectives and principally operated on a professional level..

Discussions about the democratic deficit of the European Union have gotten more intense and the criticism usually points towards a great gap between the citizens and the EU politics. In this study the political communication policy is being put under the scope to investigate to what extent the policy is designed to counter the democratic deficit, supported by the theory of deliberative democracy. The analysis examines three aspects of the deficit ? decentralization, participation and the distribution of information ? and makes research into the communicative measures that have been implemented. The importance for EU to make deliberation possible is stressed throughout the essay and in the conclusion I argue that improvements still need to be made.  .

This thesis is based on the implementation of a bilateral rural development program in Burkina Faso. The main purpose of this study was to put the actual implementation process of a bilateral development program in view. This was done by investigating how two dominant perspectives in the implementation literature can explain what in fact happens during the realization of an aid program. A further aim of the thesis was to explore the limitations of these two dominant theories, in order to get a full understanding of the complexity of the realization of an aid program. Based on the implementation theory, this study shows that the realization of an aid program can be understood from three different angles.

According to the theory of environmental Kuznets curve there is a relationship between carbon emissions and GDP. The relationship has an inverted U-shape. Carbon emissions rise initially and then decreases once a certain level of GDP is obtained.This essay interprets earlier studies in the field of environmental economics and uses public choice to seek answer on how the population acts on aggregate level. This essay analyses 115 countries in cross-sectional data. The analysis shows that there is a significant relationship between carbon dioxide emissions and GDP that is increasing at first and then decreases for a certain level of GDP.

The aim of this study is to obtain a deep knowledge about identity creation of preschool child-ren at the age of four to sex with creative pictures and its aesthetic learning processes with childrens perspective as a starting-point. The issues that I have used in this study are how childrens identity creation relates to the aesthetic learning processes in the preschool enviro-ment, how children experience the figuration of their own identity related to other individuals and the enviroment by taking different positions in aesthetic learning processes and how childrens identity creation becomes visible in preschool.In order to explore preschool childrens identity creation in aesthetic learning processes the qualitative research-oriented approach has been implemented with unstructured observations and the informal interview as the methods for data acquiring.This studys theoretical points are sociocultural perspective and symbolic interactionism. Both these theoretical perspectives emphasize the significance of communication, taking different perspectives and learning in an interaction between an individual and enviroment within given sociocultural frames of referens which results in an individuals identity development.Results from the study show that childrens painting is more than an occupation with a picture as a product. Childrens painting is rather a playfull aesthetic expression form and a relation-oriented, dynamic learning process which is related to the enriching of individual self, the consciousness and the creation of meaning within preschools frames of reference.My expectation is that my study will contribute to didactic discussions about childrens iden-tity creation while using aesthetic expression forms..

Sweden experienced a decline in exports of 16 percent in the period after the financial crisis. The decline has created a lot of question marks regarding the traditional exports which has started a process with the aim of finding Sweden?s next cash cow in export.Sweden adopted stringent environmental laws early which positioned them as a strong nation in environmental awareness. The stringent environmental legislation meant that the Swedish companies were required to minimize the environmental impact, which created a demand for eco-efficient products. Despite the early demand for eco-efficient products, the international success of the Swedish cleantech companies has been modest.The government can increase firms international competitiveness by encouraging, supporting and promoting activities on the domestic market.
