Förutsättningarna för ett parallellt generation IV system vid svensk nybyggnation av kärnkraft.
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.
Epoxidised linseed oil as hydrophobic substance for wood protection : technology of treatment and properties of modified wood
Public concern about the release of toxic compounds from wood-based products drives legislation towards enforcing industries to find and use more sustainable solutions for wood treatment. Plant oils are good alternatives to treat wood, minimizing or even neutralizing the impact on the environment. Wood modification with epoxidised linseed oil (ELO) and acetic acid as catalyst has proven a suitable method to impregnate and protect wood. However, the mixture presents a serious inconvenience because of the quick polymerization of the ingredients that limits its practical application. Therefore, this study was designed to evaluate an alternative method using a two-step process which bypassed the problem above.
Diskussionsforum på internet : Demokratiserande potential, eller en potentiell fara för demokratin?
In recent years, the right-wing extremist site Avpixlat (?Unveiled?) and the anti-racist blog Inte rasist, men... (?Not a racist, but??, IRM) have established themselves as political actors and platforms for political discussion in Sweden. However, we know very little about them and their impact on democracy.
Immunokastrering av hangrisar :
Active immunization against gonadotropin-releasing hormone (GnRH) is an alternative to surgical castration of male pigs to avoid boar taint. The aim of this study, including 128 pigs, was to evaluate the effect of a GnRH-vaccine Improvac® on performance and on social and sexual behaviour. Male pigs were assigned to three treatments; surgical castration at four days of age, immunization against GnRH and no castration. Vaccination was performed eight and four weeks before slaughter. Surgically castrated male pigs had significantly lower daily weight gain during the suckling period than entire male pigs (235 vs.
Kulturarv, efterfrågan och musikalisk mångfald En fallstudie kring bibliotekariers och användares uppfattningar om musikbibliotekets uppdrag och roll
The main purpose with this Master's thesis has been to through a case study investigate and analyze the music library activity at the Public Library in Lund, in order to find out according to which ideas and principals this activity is run by. It also discusses how you at the music department handle your task as intermediary of music and how well this coincides with the users expectations. To give the research more depth a special analysis has been made, assuming the perspective of the B&I-researcher Sanna Taljas' three perspectives regarding the music department. She identifies three perspectives in maintaining a music library, which she calls the general education, alternative and demand repertoire.The examination is based on an empirical research, where five librarians were interviewed and fifty users have responded to a survey, but the essay also includes a literary study carried out to explore which ideas there are regarding the music department's missions and roles in the existing literature.Librarians and the user's opinions coincide quite well. What distinguish the most are the opinions surrounding the competency of the music library.
ATT VÄLJA, VÄLJA OM OCH VÄLJA RÄTT: En kvalitativ studie av vad det är som styr kommuners utformning av öppenvårdsinsatser för ungdomar
The aim with this study was to examine what it is that govern the way that municipalities develop the non-institutional care for youth. An extensive development of non-institutional care for children is a visible trend in municipal social service and probable reasons for this development are, among other things, research that show inadequate results of the institution care and economy. Our main questions at issue were how the municipalities argue the priorities that have been done within their youth care services with regard to the non-institutional care and how they reason considering this? Furthermore we asked why the municipalities have chosen to develop their non-institutional care for youth the way they have and on what grounds they make their choices? This study consists of eight qualitative interviews with politicians and employees in four different municipals along with analysis of relevant documents. We have found that what governs the way that municipalities develop the non-institutional care for youth has to do with that the municipalities found it vital to find alternative solutions to the expensive and ineffective institutional care, that they comprehend that the quality of non-institutional care are higher then of the institutional care and that the non- institutional care is seen as more effective with regards to economic results and achieved treatment results.
Att vinna eller försvinna när alla får varsin dator : En-till-en-satsningar och dess inverkan på delaktighet, självbild och lärande för gymnasieelever i behov av särskilt stöd
The purpose of this study was to investigate how high school students felt that the computer helped or hindered participation and self-esteem in the learning situation and if the students experienced any differences between when they had been relatively alone in using a computer compared to when everyone had their own computer. The starting point was the national one-to-one projects made to give every student access to a personal computer and how it affected students in special educational needs and previous research. The theoretical approach was based on socioculture/activity theory and theories of self-esteem. Ten high school students in grade one at a senior high school that previously had started up a one-to-one project was interviewed. The results showed that the students primarily used the computer to write and to search the Internet, but even as a alternative or compensatory tool.
Svartgran ? ett alternativ när allt ser mörkt ut? : en kartmodell för att visa lämpliga ståndorter för odling av svartgran
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.
Systematisk riskexponering i svenska hedgefonder: Svenska hedgefonders exponering mot riskfaktorerna i Fung & Hsieh (2004) under perioden 2006-2007
This paper aims to investigate the systematic risk exposure of Swedish hedge funds using a modified Fung & Hsieh (2004) asset-based style factor model. The results show that the average Swedish equity hedge fund and fund of funds had a significant positive exposure to the equity market portfolio and the spread between small cap and large cap stocks (SMB) during the sample period. This is consistent with our a priori expectations and previous international studies. We do not find the expected systematic fixed-income related risk exposure for the fixed-income hedge funds and fund of funds in the sample. The empirical material used in this study is taken from a publicly available fund database maintained by the Swedish Financial Supervisory Authority (Finansinspektionen).
Flickors kroppsuppfattning och måltidsmönster : Förändring under pubertet och moderns betydelse
Within the ambulance care in Uppsala County a vacuum splint is used to immobilize fractures on extremities. The research available on which method of immobilizing to prefer during pre-hospital treatment is limited. The purpose of this pilot study was to examine the perceptions of the ambulance personal in Uppsala County on the issue of usability of SAM-splint and vacuum splint when immobilizing extremities. The project was also aimed at researching if SAM-splint could be seen as an alternative or a complement to vacuum splint, and to get an apprehension on any evident differences in patients? perceived pain when treated with the two different approaches. A descriptive comparative study was carried out. All patients, regardless of age and sex, with the need of immobilizing supposed fractures, were included. Patients with suspected femur fracture, collum fracture, or where pre-hospital care was not possible or in question, was excluded.
Detektering av in- och utandning vil bilkörning med hjälp av Matlab
Volvo Human Monitoring (VHM) is an ongoing project at Volvo Cars where they measure, amongst other parameters, inhalation and exhalation through a device called Respiratory Inductance Plethysmograph (RIP), on drivers. RIP measures changes in the cross-sectional area of the chest and abdomen. When the driver is in motion, such as when she is turning the vehicle, the cross-sectional area changes and noise in the RIP signal may arise.The noise results in a large number of manual adjustments in the analysis of the RIP signal, which is very time consuming and the validity of the device for measuring inhalation and exhalation is questioned.The purpose of this study was to improve the efficiency of the analysis of the RIP signal. The goal was to create a new data processing tool in Matlab that automatically detects inhalation and exhalation from a RIP signal with higher validity compared to the previous data processing tool.In this study, nine tests were performed on drivers while they were driving in different scenarios such as highway, country road and in city traffic. Inhalation and exhalation was measured using a RIP, a pneumotachograph with a tightly sealed facemask and a thermocouple placed between the nose and mouth, which was used as reference to the RIP.The result of this study was a data processing tool that automatically detects inhalation and exhalation with higher validity compared to the previous data processing tool.
Nyttjande av ofrörbrukat byggmaterial : En rapport åt Peab Jönköping
This final year project is made for Peab Jönköping and its target group is the construction industry. The main focus is the use of unutilized building material in the most economical and environmental-friendly way. Unutilized building material is here defined as material purchased for a construction project that for different reasons not has been used. The most important thing to find out was how much building material considered as being waste is actually useable material, and how much less it costs to use that building material instead of throwing it away.When this information was gathered a proposal on how to efficiently use the unutilized building material instead of wasting it was designed. Costs and incomes were investigated and the proposal suggested a storage area where Peab can store their unused building material.
Varför är det så svårt? - En studie av kulturhistoriska museers arbete med hbtq-perspektiv i samlingar
The aim of this two years master?s thesis in Archive, Library and Museum Studies is to analyse how Swedish cultural history museums work to include LGBTQ-heritage (LGBT is the acronym for Lesbian, Gay, Bisexual, Transgender and Queer) in their collections. This work is articulated around three research questions. These interrogate museum practice about collecting and collection management, what it looks like in the already gathered collections as well as the implications such work implies on a broader level. The theoretical framework throughout the paper is gender and LGBT studies as well as queer theory.
Banden mellan historia och arkiv
Freedom of religion or belief is indisputable in Human rights discourse, more discussed is exactly what it is that is included in the concept of freedom of religion or belief (in Swedish: religionsfrihet). This thesis focuses on the freedom of religion or belief in a European context, in particular on the European court of human rights and article 9 in the European convention for human rights. Some criticism has been directed against the Court to the effect that its practice and verdicts don't answer to the pronounced desire to develop a pluralistic and inclusive form of freedom of religion or belief.My aim is to examine, analyse and test three different theories, which all try to develop alternatives to the expression freedom of religion or belief, in relation to six verdicts from article 9 in Europe convention. My basic purpose is to try to find new ways of talking about freedom of religion or belief that might lead to a more inclusive, pluralistic and equal interpretation of that concept.The three theories wich I use are elaborated by Richard Amesbury (associate professor at Claremont school of Theology); Hugo Strandberg (TD at Åbo Akademi) and Eberhard Herrmann (professor in philosophy of religion at Uppsala University); and Martha Nussbaum (professor of law and ethics at the University of Chicago). The six cases from the European court are: X v.
