MCNP-modell för beräkning av neutrondos och DPA på reaktortanken vid Ringhals 2

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.

Alpin permafrost i Kebnekaisefjällen : Modellering med logistisk regression och BTS-data

Denna studie är ett försök att modellera den alpina permafrostens utbredning inom Kebnekaisemassivet i norra Lappland. En karta som visar sannolikheten för permafrostens utbredning har skapats med hjälp av data från Bottom Temperature of Snow cover (BTS) - mätningar samt statistisk modellering genom logistisk regression.Fältstudien genomfördes under mars till april 2011 med totalt 56 BTS-punkter från 1073 till 1805 m.ö.h. Permafrostförekomsten bestämdes vara en funktion av höjden. För att utreda detta användes stepwise selection som är en metod för att identifiera statistiskt signifikanta variabler gentemot en beroende variabel. De andra parametrarna som testades var topografins sluttningsgradient, riktningen av den maximala lutningen och den potentiella solinstrålningen.

Den svettiga sanningen : Bedömning och betygssättning i ämnet idrott och hälsa

Aim and questionsThe purpose for this study was to investigate how marks and mark settings are formed in physical training at some compulsory schools. We also wanted to see how the criteria for marks are formed. These were the main questions during this study.? How do the students find the evaluation and the making in physical training?? Are there differences between different student groups when it comes to their experience around estimation and marking in physical training? (gender, marks, schools etc.)? How do the teachers motivate their marking in physical training?? Are there any differences between the criteria for marking between different schools?MethodThe study was carried out during the spring 2005 at eight schools in a municipality in the middle of Sweden. The study involved 339 students opinion polls and 12 teacher opinion polls.

Omslag till böcker och DVD-filmer : en jämförande studie av visuell kommunikation i omslagen till Män som hatar kvinnor och Niceville

This thesis is about covers of books and DVD movies. I have tried to find out if the visual communication of the covers differs between the book and movie with the same story. Do they appeal to different target groups? I have also been trying to find out what designers can do to increase the visibility of covers among others. Are there certain rules to follow for making a cover visible?To reach a conclusion I have been studying components in advertising pictures, since covers work as a kind of advertiser for the product.

Indexering av skönlitteratur: En undersökning av folkbibliotek som inte köper indexerade poster från Bibliotekstjänst

The aim of this thesis is to investigate how the indexing of fiction for adults looks like in the public libraries that don?t buy indexed records for fiction from Bibliotekstjänst (BTJ). The questions that I want these libraries to answer is: - Public libraries that index fiction for adults themselves: 1. What tools do they use when indexing?, 2.

Skiftarbetets potential i byggbranschen

Two elementary schools are now being built in Gråbo (in the municipality of Lerum),Röselidsskolan and Ljungviksskolan, which are both designed with solar thermalcollectors for the schools domestic water heating. During the summer while thelargest amount of solar heat can be generated, the activity hence the domestic wateruse in the schools are heavily reduced. Both schools are connected to the local districtheating system which makes it possible to use the solar collectors to deliver heat tothe district heating.The purpose of this thesis is to evaluate the two systems mentioned above and todetermine which system is more suitable to apply on a school. The building whichconditions were used for this evaluation is Röselidsskolan.A solar heating plant of each system type was dimensioned from the expected andknown conditions of the building. The purpose with the dimensioning was to makethe solar plants replace the ordinary energy source as much as possible.

Effekt av psykodynamisk psykoterapi : - Analys av symptomförändringar från terapistart till avslutning.

Inledning: Syftet med denna studie är att, utifrån ett insamlat material vid S:t Lukas mottagningar i Stockholmsområdet, undersöka symptomförändring från start till avslutning i psykodynamiskt inriktade psykoterapier.Frågeställningar: Den övergripande frågeställningen är om patienter och terapeuter bedömer att terapierna haft någon effekt och i så fall vilken. Vidare om bakgrundsfaktorer och självbild påverkat symptombelastningen.Metod: Studien har genomförts med hjälp av självskattningsformulär som fyllts i före och efter behandling. Patienterna har fyllt i Symptom Checklist (SCL-90) och terapeuterna ett frågeformulär där de skattat patienternas besvär. Efter inomgruppsjämförelser har jämförelser gjorts med ett normerings-material.Resultat: Det sker en signifikant symptomlindring under terapierna. Störst är förändringen när det gäller depression, ångest och interpersonell sensitivitet samt i det sammantagna genomsnittsvärdet.

Jämförelse av solhybrider

Research in solar energy is taking big steps in both solar heating and solar electricity. It´s not only the technologies alone, but also the combination of both solar electricity and solar heating which is what is called a solar hybrid. The idea of a solar hybrid is that a solar cells efficiency decrease with increased temperature and can with help from a solar collector be cooled and the heat can be utilized. This thesis report compares heat production and electricity production with respect of, in first hand, a solar hybrids geometry in the cooler. The theory chapter describes solar heating and how different solar cell technologies work and their environmental impact at the production and how compatible these technologies are for the solar hybrid.

Likhet och särart - en studie av Internationella biblioteket och dess besökare ur ett mångfaldsperspektiv

The underlying purpose of this study is to see whether a library focused solely on providing literature in other languages than Swedish serves as a unifying, integrating force, or as an agent for division and exclusion. The study focuses on the International Library in Stockholm. The authors have created a profile of the visitors of the selected library, concerning their characteristics, their library habits and their perceptions of the International library. This profile has then been compared with the staff?s perception of the visitors as a group.

The influence of active bomas on habitat choice of the common warthog (Phacochoerus africanus)

The common warthog (Phachocoerus africanus) is a relatively long-legged pig with noticeable curved tusks, a short neck and three pairs of facial warts. It has four recognized subspecies. The common warthog is a non-migratory ungulate living on the African savannah. It is a hindgut fermenter and predominantly dependent on high-quality foods. It prefers open areas for grazing but use bushes for cover.

Governance och genus- en pilotstudie om att analysera ett nutida stadsvetenskapligt begrepp från ett genusperspektiv

Following essay discusses the possibilities of using a gender perspective when studying local governance within a Swedish context. Governance is an international concept used to describe a more lose, informal and network based way of doing politics The main purpose for conducting this essay is that traditional theoretical frameworks used in the study of local politics are not enough to fully conceptualize the complexity of our changing political environment.After a broad summing up of what had been done in the recent decades within Swedish political science on the topic of local politics and gender I came to the conclusion that so far nothing had been written on governance. The next step was therefore to conduct a pilot study to cover the subject matter of governance and gender. The study was based upon interviews with five female politicians in Malmoe city.Results showed that governance, in terms of informal networks did exist, and had influence over the local politics. Some of the networks were male dominated.

Ekonomiska konsekvenser för skogsbruket vid avsättning av mark för viltvårds- och jaktändamål : en fallstudie på Svenska Jägareförbundets fastighet Öster Malma

The value of game for hunting from a social economic viewpoint is an interesting topic that is currently being investigated in a Swedish research program. The amount of damages that the game stocks cause to the forestry is, and has been in focus for a longer period of time. Something that I saw as missing was an investigation of how much an active game keeping measure might cost in lost incomes for forestry in terms of reduced acreage for forest production. This question was the foundation for this investigation, which purpose is to give interested persons with decent knowledge of forestry an example of how cost estimation for forestry resembling the example that is studied can look like. The measures that has been taken is a felling of forest in different ages on both sides of a forest dirt road to create increased asset of forage for the game, and at the same time give hunters that have their post along the dirt road a better chance of seeing passing animals early and increasing the possibility to shoot good shots. The area, which is a part of The Swedish Association for Hunting and Wildlife Management estate Öster Malma, is also used as an example for guests who wish to learn more about managing ungulates. These guests have now got the opportunity to get information on how big the costs are for the measures that have been taken. The main conclusions of this work is that changed timber prices and foremost a change of interest rate makes big differences on the result of the calculations.

Översättning och validering av pVHI : för barn 6 till 10 år

Studies indicate that between 6-9% of all children has some type of voice problems. Voice problems in children may have different etiology and can affect all ages. In Sweden, there is a lack of a standardized questionnaire addressed to children with voice problems and their legal guardians. The purpose of this study was to translate and validate the Pediatric Voice Handicap Index (pVHI) in Swedish children aged 6 to 10 years. The study was carried out through an internet-based assessment form for children referred to speech and language pathologist/ phoniatrican due to voice disorders in Sweden and a matched control group of children without voice problems.
