A new build in the Swedish nuclear power system would entail increased re-quirements for the proposed repository, which is adapted after the reactors of today. With a fast reactor, capable of burning nuclear waste, operating in parallel with the light water reactors, the increased requirements on the repository could be reduced.In this thesis, simulations of a light water reactor and a fast reactor have been performed by using the Monte Carlo code Serpent to investigate the changes in the fuel inventory. The light water reactor in the study is a boiling water reactor and the fast reactor of the type sodium-cooled fast reactor and they have been used for three different operation scenarios.By studying the fuel composition and the results from the simulations of the three scenarios conclusions can be drawn. Conclusions regarding the change of the fuel inventory and decay heat in Clab as well as the interim storage facility and in the repository. Depending on the operation alternative the changes dif-fered significantly and especially regarding the mass of burned actinides for different fuels in the fast reactor.The lowest increase of fuel assemblies was meet when using 50 years old fuel with 20MWd/kg U burnout and 2,0 % enrichment for start up of the fast reactor and 30 years old fuel assemblies with 50MWd/kg U burnout and 4,7 % enrichment for the further operation of the reactor.The increase of the number of fuel assemblies was 3174, which is equivalent to 641tons of heavy metal.

The purpose of this study is to illustrate how some teachers in multicultural school environments reflecton and experience the educational work with national tests in the third grade for students who do not have Swedish as their native language. The research questions I have chosen to work with are:How do teachers experience working with national tests in groups of students where there are children with Swedish as a second language?How do the teachers reflect on the students linguistic preconditions relating to the national tests in these groups of students?What strategies in their teaching on national tests do the teachers use when it comes to students with Swedish as a second language?In this study I have chosen to use a qualitative interview method. Since the purpose of the study is to understand how teachers reflect on students with Swedish as a second language the obvious choice was to interview teachers who work in a multicultural school. In my thesis I have chosen to use sociocultural theory, Cummins four quadrant model and context for theoretical approach.

AbstractThe Energy Declaration is a law that will come into effect October 1: Th 2006. This report has Värnamo municipality as principal and shall clarify what the estate owner in general and Värnamo municipality in particular need to know about this law. Another part that is going to be dealt with is how large the future need for energy experts in this field will be, and which competence that will be demanded for them.The work will in general deal with simplified energy declarations for apartment houses and public buildings, since these buildings are the first to be involved with energy declarations.The energy declaration will consist of a number of important components.? Energy power i.e. how much energy the building consume? If the ventilation control is done? If the radon measurement is carried out? Recommendations of measures to improve the energy power? Reference value to compare the buildings energy power againstAccording to the law the declaration shall been made by an independent expert, which will need certain information for this.

One of the city of Stockholm?s main objectives is to have a society completely free from fossil fuels. To achieve this, several investments regarding improvements in energy efficiency and renewable energy are currently being planned or implemented. One of these investments is a project called Hallbara Jarva which is located in the suburbs of Stockholm. The purpose of this thesis is to examine the prospects of an investment in photovoltaic cells from an energy-saving and economical point of view. The analysis is limited to three buildings within Hallbara Jarva and is intended for the property owner.  Solar energy is a type of renewable energy source and is commonly divided into solar heating and solar power.

The purpose of this study is to explore specific pedagogical activities that benefit the student's verbal language development and to learn more about how our schools use teaching methods to achieve the ambitions in the governing documents in Sweden. The aim is finding the correlation between theory, research, governing documents and the educational work in our schools. This study contains an empirical survey in intention to see how teachers, pupils and school administrators experience school activities, to see if those activities are formed with the intention for pupils to reach the learning goals according to the governing documents.The aim of this study has been achieved by relating empirical data with theories and previous research on conversation analysis. Goffman's and Norrby's research on the importance of dialogue and previous research on dialogicity studied by Dysthe, Vygotsky and Bakhtin are presented. Those are related to empirical data and show that most teachers realize the importance of integrating dialogues in daily activities and in different learning contexts.

The objective of this study was to examine three common mobile phoneplatforms in relation to their network traffic features. The platforms to beexamined are Android, iOS 5 and Windows Phone. After the investigation wascompleted a prototype application was implemented in order to demonstratethese features in the most suitable platform. The application will function as atelephone call exchanger. In addition, the application must also send the userstatistic to a Web server, accept contacts from a Web server, as well as having aspecial administration part in which the userstatistc can be presented.

The purpose of this study was to examine social workers working process in social assistance with focus on the child´s perspective. We were interested in learning about the existence of variations in approach and attitude between two municipalities. Question to be answered about what methods and approaches used by social workers to include the child´s perspective in the process of social assistance. Another question to be answered about what the manner in which social workers took into account the child´s perspective when the families apply for social assistance in relation to the operations and requirement. To fulfill the purpose, qualitative methods were used.

The Swedish government has made the decision to transform the talking book system from an analogue system to a digital system called DAISY by the end of 2004. The purpose of this Masters thesis is to examine how public libraries are affected by this system change. This is carried out by studying the current situation in public libraries concerning the transition to DAISY. This qualitative oriented study is primarily based on interviews with four librarians and three library managers at six public libraries. Management by objectives is here seen as a suitably theoretical framework since public municipal libraries are partly regulated by the governments goals and laws.

The aim of this paper is to elucidate and analyze history teacher's didactic choices in the conflict between unequal educational materials and the requirements of equality in the curriculum of Swedish secondary school. The empirical data consists of interviews with five secondary school history teachers, observations of their lessons as well as analysis of their tests. The starting point was to investigate teachers' didactic work in the role as a bridge between the non-equal historiography presented in textbooks in history and the curriculum?s demands for equality. Three different approaches have been observed in the teachers' didactic work when considering gender perspective into their teaching: that women become extensions in a male-dominated historiography; that another part of the story is presented when a gender perspective is considered; and that the gender perspective is included in history teaching and becomes an integral part of all the content of the subject.Several of the teachers acknowledged that gender equality is less prioritized than the courses core content and related assessment criteria.

In this report an MCNP (Monte Carlo N-Particle) model is described for the reactor vessel at Ringhals 2. The model is validated against the specific activity in neutron dosimeters, extracted in 1977, 1984 and 1994. The validation showed that the calculations of the model are within the requirements of a maximum of 20 percent uncertainty for every neutron dosimeter except one, extracted after the first cycle. The uncertainty of this cycle was mostly due to the operation data rather than to the MCNP model.The model has been used to investigate various questions concerning radiation damage. The reliability of the traditional measure of radiation damage, fast neutron flux (En > 1MeV) has been evaluated.  This has been done by taking the ratio for this and another measure of radiation damage, DPA (Displacement Per Atom), for various positions and layers.

A common problem in forestry is plant death caused by frost. The risk of frost is highest on wind protected, flat or low-lying areas in the terrain. Here you often have regeneration problems with Norwegian spruce which is especially sensitive to spring frost. Swedish tree experiments have shown that the black spruce can be a suitable alternative on these areas, for example on moisture frost prone areas. The species originates from North America and its pioneer tree characteristics make it more frost hardy than Norwegian spruce.

This thesis seeks to investigate how an agreed written form requirement is met in an electronic environment. Swedish Contract law is applied since Sweden lack specific regulation for electronically closed agreements. Since contractual freedom prevails in Swedish law, it is up to the parties themselves to decide if the formal requirements to be applied.In order to assess whether the written requirement is fulfilled in the electronic environment, a purpose-oriented analysis should be made. When the purpose of why a written form requirement applies has been clarified, the analysis continues to assess whether the objective can be achieved with the modern form of communication. The method is called functional equivalence and means that when an electronic media fulfill the same functions as the paper medium so will the electronic medium as a starting point to give the same legal effect as if it were the case of a written paper document.

The purpose with this study was to systematically examine scientific studies of audiologic group rehabilitation. The definition of audiological rehabilitation was explored, different variables that influence the result and how the outcome measures should be done and its relationship with the goals of audiologic rehabilitation. The method used was a literature study. Pubmed and Cinahl were used for the search of literature. Some articles were searched from scientific studies reference lists and also advice from the supervisor.The result from the different studies shows that the effect of rehabilitation varies as there are many aspects that have an affect on the outcome measure.

AbstractIn urban societies people spend more and more time indoors, which put great demands on the indoor environment. If the ventilation is to manage the removal of unwanted substances in the indoor air, a good mixing of the air is required. The question arises that, whether the buoyancy forces will counteract a good mixing of the indoor air or not?This report aims to clear up the difficulties whether you need to consider the buoyancy forces or not, when adjusting a ventilation unit. For studying the indoor mixing of the air a two dimensional model is constructed in COMSOL Multiphysics.
