Abstract The accident in 1986 at the nuclear power station in Chernobyl, Ukraine, dispersed radioactive cesium over large areas of Europe. The half life of 137Cs is 30 years and this radionuclide also behaves like potassium, which means that it can easily be taken up by the vegetation or be adsorbed in to the structure of clays, principally illitic clays. When radiocesium decays ionizing radiation is emitted, which is harmful to humans that are exposed, either directly or indirectly through food intake. It is there-fore important to know what happens to the cesium that is dispersed into the environ-ment. In this project a simulation model was constructed to simulate the adsorption and transport of radiocesium in the soil and plant uptake.

This basic data of knowledge for a future maintenance programme concerning the park at Kungsholmen is made up of 3 separate parts. 1.) A historical documentation 2.) A mapping and documentation of the objects status of today. 3.) An analytical evaluation complemented by a maintenanceproposal for the historic park. The aim of the document is to serve as a future basic data for decision making, based on the aim to preserve and develop the described cultural values of the object. The different parts can be used separate or altogether in order to define or redefine new goals..

I denna uppsats studeras förekomsten av värden i geometrikapitel i läromedel för gymnasieskolans Matematik A. En metod baserad på innehållsanalys som använts i en tidigare studie om förekomst av värden i algebrakapitel har vidareutvecklats. Sammanlagt 955 uppgifter i geometrikapitlen i fem olika läroböcker har analyserats. Resultatet visar på en skillnad mellan intentionerna i gymnasieskolans styrdokument och det utrymme olika värden ges. Även skillnader mellan det utrymme studerade läromedel ger åt olika värden har påvisats..

Vilka diskurser ger elever och lärare uttryck för i pianoundervisning? Syftet med min uppsats är att undersöka hur pianoelever och pianolärare på kulturskolan och inom ett studieförbund genom språket ger uttryck för en mängd förhållningssätt och attityder. Vad sägs i samtalen kring deras undervisning och vilka diskurser och tankekollektiv bildar dessa åsikter tillsammans? Jag har använt mig av fyra djupgående intervjuer och två videodokumentationer för att dels studera elevernas och lärarnas uttryckta upplevelser men också för att ta del av det som verkligen sker under lektionstid. Teoretiska utgångspunkter har utgjorts av kritisk diskursanalys, institutionsbegreppet och interaktionsteori.

This study analyses social age as a phenomenon and if unaccompanied refugee children has a social age that, according to the Swedish culture, do not correspond with their biological age and if so is, the reason for that. Furthermore, our study has discussed the potential consequences of the effects for the unaccompanied refugee children and the social age when interacting with Swedish society. According to our study, the social age is effected by other factors besides cultural norms, values and role expectations that a society has on a specific biological age. The results in this study shows that social age is a vital component to someone?s identity.

The purpose of this study was to examine how commitment to a cause on a local basis had developed in four smaller groups during one decade. In 1996 I interviewed representatives in Åsele, Borrby, Hasslarp and Tving about their commitment and citizen initiative. Now, ten years later, I followed it up by interviewing them again. I wanted to know if the groups/associations still existed, if they had achieved their goals as they where pronounced ten years ago and how a strong commitment on a local basis can develop during ten years. Which phenomena decide whether the group develop or phase out? I use the term citizen commitment instead of citizen initiative to stress the fact that it is no longer an initiative but an on-going commitment.

Syftet med denna kvalitativa studie är att undersöka vilka etiska normer som finns i lärares resonemang om vardagens problemlösning och konflikthantering. Vidare syftar studien till att undersöka hur lärare resonerar om sin handlingsberedskap och sitt beslutsfattande samt vilka etiska normer de grundar sina beslut på. Vår datainsamling har skett genom ljudupptagning av halvstrukturerade intervjuer med fem lärare. Lärarna har dagen innan intervjutillfället fått ett fall med olika etiska dilemman som de ombetts att läsa och reflektera kring. Intervjuerna har utgått ifrån fallet, men lärarna har uppmuntrats att relatera till egna erfarenheter av etiskt svåra situationer i läraryrket.

Drinking water is produced from raw water and is either from groundwater or surface water. This thesis aims to find out if the cleaning process of raw water is sufficiently effective. This is important because consumers are otherwise at risk of waterborne infection caused by pathogens. There are three groups of pathogens; bacteria, virus and parasite. These have different characteristics which mean that they require different water treatment to be separated.

Summary The estate of Johannishus is situated in the south of Sweden and in the province of Blekinge, about 8 kilometres from the city of Ronneby. The main building together with the park represents the province´s only example of a well preserved estate environment from the early 1800th Century, and was declared as a historic monument in 1982 because of its unique role in the province. Johannishus Park has during 300 years developed in close relation to the main building, the landscape and the surrounding infrastructure. Each century and owner has had an influence on the park, which has resulted in an interesting visible cross-section of 300 years of Swedish garden history. Most noticeable today are the traces from late 19th Century, but in its oldest parts the park contains structures from the early 18th Century.

This thesis discusses how the education in the Master of Engineering program can change to become more into line for the students needs, especially for the women, both directly in the education situation and later in their occupational roles. This is done using a gender perspective. Both the education and the occupation today is characterised by masculine norms and values. The education lacks gender perspective and is created by men, for men. The thesis gives concrete proposals on how to change two existing courses to better fit the students.

The subject of this essay is the target audience consisting of males in the ages of 25-40 living inStockholm with academic background. The main subject is to describe the target audience in awider perspective and to look at their social media habits and see if there are any differencesbetween the younger and older half of the target audience and to compare the results with theoryabout generation x and y. The split of the target group is made in the middle of the target age rangeso the two subgroups consists of informants in the age of 25-32 and 33-40. The study will beconducted through semistructured qualitative interviews. The aim of the study is to see if there areany differences in social media habits and some basic values between the two subgroups..

Through participant observation in a local promoter group of hardcore punk shows inGothenburg and qualitative interviews with its members I have investigated links between taste in music, values and social structures in the hardcore punk scene. The theoretical framework of this essay is built upon the concept of subcultural capital, which is adapted from Pierre Bourdieu and developed by Sarah Thornton and Keith Kahn-Harris. The result shows how members among the hardcore punk scene create and preserve distinction towards others, while the distinction becomes important benchmarks for including and excluding practices in the scene..

Due to fast growing and rapid changes in markets today, most of the organizationsthat are trying keep up with these changes have a high demand for software that areof high quality and comes with a low price. To meet these goals software companieshave to implement new methods to develop software that are suited for rapidchanges. The concept of agile methods can fulfill this need. Our purpose with thisthesis was to investigate how well agile methods could be applied in organizationsthat could be identified as adhocracies. A case study was conducted in anorganization which we could identify as an adhocracy.

The building industry consumes approximately 40 % of the total energy consumption in Sweden, where the using stage is dominating with 80 %. There is a lot of work in progress to reduce energy use in the building industry, and the demands from authorities regarding energy use increases. As a part of this work Building and planning department of Sweden has established a requirement that has been applied since 2006, and restricts a maximum energy use for buildings.The requirement includes that an energy simulation must be done in advance to demonstrate that it is possible to meet the demands.Reality is however more complex than an energy simulation program, that frequently underestimates the energy use of buildings. The purpose of this thesisis to study and analyse deviations between estimated and actual energy use in modern apartment buildings. The study includes four apartment buildings in Stockholm, Gothenburg and Jönköping that were built in 2007-2009.
