Tyr ? A historical and comparative study of configurations and formations connected to the Old Norse god Tyr. Klas af Edholm This thesis has two aims. One is a discussion of the history of the study of Old Norse religion and related aspects, centered on how general tendencies within the area of research have affected the interpretations of the god *T?waz/Tyr.

The purpose of this study is to discuss the use of social media by the Swedish Police for democratic purposes. The idea of citizen empowerment is closely related to the development of new communication technologies such as social media. Yet many studies indicate that governmental institutions rarely make use of the assumed potentials of social media.In this study, the democratic potential of social media is derived from Habermas normative concept of deliberative participation. Operational definitions emphasize discursive equality, interactive reciprocity and external impact. The analytical framework is combined with qualitative text analysis to highlight the conditions of interaction between representatives of the Police and citizens.In conclusion: the democratic potential of social media, from a Habermasian point of view, is to a significant extent neglected at the expense of its strategic advantages.

Most of the city of Uppsala rests on postglacial clay with a varying content of sulphur. The sulphur occurs naturally in the clay in reduced form as sulphide and the clay is for that reason usually called ?sulphide clay?. Excavation during construction activities gives rise to large amounts of excavation material, of which the sulphide clay is a considerable part.When the clay is exposed to air and water, an oxidation of the sulphides occurs which may produce an acid leachate and the mobilisation of heavy metals bound in the clay or underlying material. The aim of the work has been to improve our understanding of the behaviour of sulphide clays and produce a basis for risk assessment in the future handling of excavation material with high sulphide content.

The research group Soil and Water Management at the department of Soil and Environment at theSwedish University of Agricultural Sciences in Uppsala are studying greenhouse gas emissions fromcultivated peat soils. To measure carbon dioxide emissions from peat soils in the field the researchgroup are now using two portable carbon dioxide meters (Vaisala GMP343). For practical reasons,they plan to acquire a new type of automated field meter. The aim of this study is to evaluate thepresent meters to see how environmental conditions and instrument settings affect the results,which is meant to facilitate the introduction of the new field meter when the meters needs to becompared. As a part of the study the relationship between groundwater level and carbon dioxideemissions from peat soils will be investigated.The evaluation of the two carbon dioxide meters was made by connecting them to one single airtightsystem, with the aim of creating identical measurement environments.

I det här arbetet undersöks och jämförs två olika sökalgoritmer när de används för implementation av AI-spelare till brädspelet Pentago. De två algoritmerna som användes var alfa-betabeskärning och en nyare algoritm som kombinerar genetiska algoritmer och minimax, kallad genetisk minimax. Utvärderingen av resultaten visar att alfa-betabeskärning passar bättre vid implementation av en AI till Pentago än genetisk minimax. Alfa-betabeskärning med ytterligare optimeringar har potential att lämpa sig väldigt väl för implementation av spelare till Pentago. Ytterligare visar resultaten att genetisk minimax inte är en passande algoritm för AI till Pentago.

Stockholm har inför 2050 satt upp ett mål om att bli koldioxidfritt. I strävan mot detta söker man utvinna energi med förnybara metoder och ett alternativ för elproduktion inom stadskärnan skulle kunna vara solceller. Solceller är en teknik som genom sammanfogande av halvledarmaterial och den fotoelektrisk effekt genererar el ur solinstrålning.Avhandlingen studerar dagens solceller, med verkningsgrader uppemot 20 % och deras potential att täcka den mindre del av Stockholms elbehov som idag härstammar från fossila bränslen. Genom att se till en uppskattad befintlig takyta i Stockholms kommun och jämföra den med ytan som baserat på solcellernas potential behövs för att täcka behovet, konstateras att endast en liten del av detta kommer kunna täckas. För att solceller skall vara aktuella inom storskalig elproduktion, krävs att de är ekonomiskt lönsamma och att det i dagens läge är praktiskt genomförbart att montera dem inom stadskärnan.

A new type of chartered holiday, fitness holiday, has evolved during the last years and has also been mentioned in different media channels. Despite this, fitness holiday is a relatively new and unexplored phenomenon, which caught our interest to further explore this. The desire to travel on a holiday of this type has also increased. Therefore, a study about this particular phenomenon with focus on the traveler?s motives behind the choice to go has been done.It?s a qualitative study and most part of the data has been collected during a field study to Playitas Resort, Canary Islands.

The aim for this paper has been to examine three textbooks designed for science education in upper secondary school in order to determine whether they convey any specific attitudes regarding what is considered to be ideal knowledge within the field of biology. The main focus has been to investigate if different types of design strategies have been used to emphasize certain values or attitudes and if this proves to be the case, how is this achieved specifically?                      For this purpose I have conducted several different qualitative linguistic analyses of the textbooks. The theoretical framework for the analyses lies within the main field of critical linguistics and more specifically in the context of systemic functional linguistics. The two main language models I have chosen to use for my investigations are functional grammar and multimodal text analysis.                      My results imply amongst other things that by conducting an overall assessment of the headlines in the textbooks a fair assessment can be made of which overall attitudes the books convey.

Research concerning movement patterns of wild animals has been advancing since GPS technology arrived. But studying the snow leopard (Panthera uncia) is still difficult because of the harsh territory it inhabits in Central Asia. This study took place in south Gobi, Mongolia, and aimed to estimate the time spent at kills and the maximum distance away from kills between visits. Snow leopards were monitored with GPS collars that took a location every five or seven hours. Potential kill sites were established by identifying clusters of GPS-locations in ArcGIS and visited in the field for confirmation.

Syftet med denna studie är att undersöka vad som händer i olika naturvetenskapliga situationer i den fria verksamheten i förskolan. På vilket sätt tas sådana situationer tillvara på av pedagogen? Jag har använt mig av videoobservationer i två förskolor i Mellansverige för att försöka upptäcka situationer i den fria verksamheten som har potential att bli en naturvetenskaplig lärandesituation för barnen. I studien observerades 11 pedagoger. Resultatet visade att det finns potential för att utveckla naturvetenskapligt lärande för barnen i den fria verksamheten i förskolan.

In this project a method used for performing accurate simulations on magnetization dynamics based on constrained field density functional theory has been validated and used for performing computations on a few magnetic materials. The method has been shown to simulate systems consisting of iron well, but there are still problems with simulations of alloys containing both magnetic and non-magnetic materials..

In classic academic social studies of East Europe, terms as Communism and Post-Communism are commonly used to describe the main characteristics of this geographically imagined area. This paper makes a not so frequently seen attempt to apply Post Colonial Theory for the same field. With start point in Post Colonial theoretical writers, the author wants to find a East European Post Colonial version for the internal Europe which will supply tools for a discourse analysis of the European mind map divided into West and East. The material consists of interviews with three Swedish and three Czech officials, all working with European politics in their country's Ministry of Foreign Affairs. The analysis is carried out with inspiration of Ernesto Laclaus and Chantal Mouffes Discourse theory.

The term socken ? comparable to the English term parish ? refers to a historical geographical entity found in rural areas of Scandinavia. This entity presents a multi-layered understanding of the local rural area and is in this essay conceptualized as a place. The concept of place is central to geographic work but it is also a contested term ? discourses within the field of geography present different perspectives on place as a geographical concept and our understanding of it.The history of parishes goes centuries back.

In this thesis I discuss and analyse the use of violence of Basque radical nationalists after the 11th of September 2001 and the bombing of Madrid the 11th of March 2004. The field study is performed in the Basque country with interviews both on the French and Spanish side of the border with representatives from the Basque Nationalist Liberation Movement (BNLM).After the 11th of September the Spanish government continued its struggle against the countries own terror - ETA. But as the research will show the new political context after the 11/9 made it possible for the state to intensify the labelling of groups from the BNLM as terrorist organisations and thereby putting its members and leaders in prison for terrorism. My research shows that this social change may lead to a mobilisation of activists inside ETA, which in turn might create a continuity of the group's use of violence. The scenario is though challenged by an other setting in which the political situation after the 11/9 have made use of violence by militant groups like ETA illegitimate and irrational as a consequence of the mental trauma among the people of the western world.

This thesis concerns waste management on construction sites and was conducted on behalf of ICA Fastigheter.Areas of concern:How can an environmentally-efficient waste management system on construction sites be defined? What potential exists for exploiting the waste resources that are generated?How can the waste management be optimised by reducing the quantity of waste and by optimal sorting?How can the client of a project influence the waste management?The purpose of the work was to investigate sustainable waste management in the building and construction sector and to highlight waste as a resource from an environmental and economic perspective.The aim of the work was to define an environmentally-efficient waste management system, to analyse the potential that exists in waste management and to draw up guidelines for optimal waste management.The method consisted of a literature study, two visits to construction sites and four interviews.An environmentally-efficient waste management system means that the waste is managed in the following order of priority:Prevention     Reuse  Recycling     Energy recoveryLandfill     The prevention of waste is an important area that has not been adequately explored by the building and construction industry. The quantities of waste could decrease with the implementation of measures such as ordering materials in the dimensions required, prefabricated components, logistics centres with Just-In-Time deliveries, less and improved packaging and less wrapping. The reuse of waste materials and temporary apparatus as well as the use of a return pallet system are examples of reuse that reduces the quantities of waste.In most cases the source sorting work is a matter of course and the proportion going to landfill is down at a low level. The source sorting can be optimised by sorting all materials that can be reused and recycled to use them as a resource.
