Water is our most important provision and its quality is above all dependent on the geological conditions in the area from where it is extracted. Due to geological properties there are certain areas with an elevated risk of high uranium levels in the ground water, which in turn constitutes a risk for human health. Consumption of water that contains a high concentration of uranium implies a health risk due to the chemical characteristics of uranium. Livsmedelsverket (The National Food Administration) and Socialstyrelsen (The National Board of Health and Welfare) therefore recommend that precautionary measures should be taken when the uranium concentration in ground water exceeds 15 micrograms per litre. In particular, drinking water collected from wells in areas with uranium-rich bedrock may have a harmfully high level of uranium. One of the wells of the Ärla water purification plant, located near Eskilstuna, Sweden, contains water that exceeds the guideline of 15 micrograms per litre. One interesting technique for removing uranium from drinking water is adsorption to reactive filter materials.

This examination project is carried out for Waséns Traffic School in Linköping. The task was to develop a completely new windows application and a webpage that connects to the same MySQL database. The windows application (ATSV) is a program intended to carry out all the administrative tasks that a clerk at a traffic school may need: pupil management, reservations, billing and register functions. The applications was developed in C++ using Visual C++ from Microsoft. The connection to the MySQL database was made possible by using the class package MySQL++.

Since 1928 the Swedish accounting and taxation has been closely linked by law which today as the European Union works with its harmonisation of the European accounting systems brings up difficulties. The Union strives to integrate the countries different ways of accounting in order to make it easier to use and understand foreign information. The Swedish connection between accounting and taxation means that a harmonisation would change the whole system as its known today. The purpose with this study is to examine what the link between the two means and how a decoupling would affect Swedish accounting and auditing. We also want to examine how the Swedish taxation office, who currently uses the accounting as a ground for taxation, could guarantee the quality of the declaration without a proper underpinning. The study shows that a decoupling could lead to an increase in quality on swedish accounting and that the administration would become more difficult to handle. The risk of dividend of untaxed profits is not seen as a problem in this context.

The purpose of this essay is to investigate how parents of children with ADHD or autism experience the transition between preschool and preschool classes. To get answers to my questions, I interviewed five parents representing three different schools in one municipality. I have chosen to use a qualitative research interview inspired by phenomenology. The results of this study show that parents perceptions differ, in terms of how well the transition work for children, and how support and treatment are at a transition. For children with a documented diagnosis, schools have an action plan for those in the gray area there are no procedures.

This is a paper about the effects from smoldering fire on lithic objects from an archaeological view. The introduction gives the background to this paper, a short orientation to forest wildfires and why the work is limited to: flint, quartz, quartzite and slate. Material and methods describes the stone materials and the setup that was used in the temperature logged tests with three replications for each type of material. The fuel in the burnings was peat on a bottom of sand. Flint showed a more drastic effect from heat compared with the other materials. Slate seems to have greater tendencies to change to darker colour and luster at lower temperatures than the other materials.

This paper aims to examine how, and if, music is being used integrated in other subjects thanmusic in school. The study is based on qualitative interviews and I haveinterviewed fourteachers, regardless of whether they use music a lot or not.The questions the study is basedon are if there might be a connection between theteachers' own feelings for music andwhether they use music inschool or not, how music is being used and does the use of musicgive any effects?The result of this study shows that there can be a connection between the teachers ownsfeelings for music and the fact if they use music when they teach or not. One of the teachersI?ve interviewed had bad music experiences and didnot use music in her teaching.

This thesis discusses the representation of bodies in todays non-fiction television in Sweden. I have chosen to focus on deviant bodies (sexual, deformed or unhealthy) on display in reality-shows and documentaries on SVT, TV4 but especially on the commercial channels TV3 and Kanal5. Also discussed are the viewers emotional and bodily reactions. Altough these shows are different from one another in many respects, I argue that there is also a common thread between them. From a sociological and cultural perspective, and with help of some historical examples, I try to illustrate how we view these shows and what their function is.

Semi-natural grasslands have a high biodiversity and host ecologically and economically valuable ecosystems and species. Restoration on these types of land is often done by removing trees and scrubs, mowing, grazing, changing the soil by removing nutrition or changing the structure of the ground. Another way of restoration is planting seeds of common grassland plants. By comparing 18 scientific publications I investigated if the restoration was affecting the plants in a positive way and if the effect was similar for insects. By comparing the publications, time seemed to have an important effect on insects. They needed time to recolonize restored areas.

Policy document conversion in practice ? a qualitative study of five upper grade teachers approach to the 2011 policy documents in history.This essay examines five upper grade teachers approach to the new 2011 policy documents in the history school subject, as well as it?s impact on the teachers class room activities. Also, the study examines what factors have influenced this conversion process. Colleagues, the school management and the Swedish Skolverket (the Swedish school management organisation, controlled by the Swedish government) are in this study the main external influences that are studied. The study is carried out with an organisation theoretical approach, witch states that controlling the schools practical activities is hard, taking in to account a great variety of ?problems? that follow a teachers every day work.

Popular culture is a phenomenon of growing importance in the society today. Children and teenagers are increasingly using popular culture in their everyday life to reflect and answer questions about their identities and the meaning of life. Swedish primary and upper secondary schools are expected to prepare their students for adulthood and to provide them with tools to explain understand and problematize contemporary society. From this perspective it is relevant to question whether the schools achieve this and whether the instruction given there represents the contemporary society. For the purpose of knowing more about how popular culture is perceived and dealt with in the Swedish education system, this study examines how eight textbooks in Religious Education (RE) and the national curriculum for upper secondary school discuss and treat popular culture.  The study focuses on when and in what ways the textbooks mention popular culture and if the curriculum provides any supportive base for including popular culture in religious education.

We are working on the development and design of an approach to agents that can reason, react to the environment and are able to update their own knowledge as a result of new incoming information. In the resulting framework, rational, reactive agents can dynamically change their own knowledge bases as well as their own goals. An agent can make observations, learn new facts and new rules from the environment, and then update its knowledge accordingly. The knowledge base of an agent and its updating mechanism has been implemented in Logic Programming. The agent?s framework is implemented in Java.

The purpose of this work is to investigate what students in grades 4 to 6 at a school in southern Värmland know about cyber bullying. It also aims to find out whether there is or has been any cyber bullying in grades 4-6 at the school. The issues at work are what do cyber bullying? Is there a difference between cyber bullying in the different grades? (4-6 grades) Are their differences in cyber bullying when it comes to sex? And there is no connection between the mental bullying and cyber bullying? The material for the work was collected through a questionnaire survey conducted with students in grades 4 to 6. The survey was conducted anonymously, they were asked what sex it was and what grade they are in.

The swedish education system in general and the swedish gymnasium in particular is at the point of a thorough reform of the guidelines in education. One major difference given in the guidelines is that the former core subject of arts education is abandoned in favour of making history a mandatory class. This despite the curriculum outlined in 1994 remains. Through comparativ text analysis of the documents and reports outlining this reform and defining the curriculum as well as the guidelines for the education system this study aims to point out the reasons for this change. Through in depth interviews with teachers, educators and authorities in addition to readings of contemporary research on arts in education the study will depict a larger picture of the scheme of things.

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.

Over the past 40 years 600 000 ha of lodgepole pine (Pinus contorta ssp. latifolia (Engelm.) Critchf.) has been planted in Sweden (280 000 ha on SCA's forest land alone which represents about 15% of the company's total forest land area). In the early 70's SCA situated a number of experimental stands in order to investigate different aspects of the exotic tree, primarily growth rate. To be able to compare the two species plots with scots pine (Pinus sylvestris L.), this species was also planted at the same time and under the same conditions. A number of questions should always be raised when exotic species are introduced in an ecosystem. Invasiveness, the pathogen situation and purely ethical issues should be discussed.
