The purpose of this thesis work is to evaluate how the physical behaviour of a pipe bend is affected by the pipe bending procedure. Effects such as initial ovalization, thinning, thickening and plastic hardening from the bending procedure are examined and the mechanical properties of pipe bends containing these effects are investigated.This has been evaluated by creating a detailed Finite Element model of a pipe that is being bent. Then the differences compared to a bent tube in a virgin state, so called Elbow elements and an analytical in-house program have been evaluated. The virgin state refers to a model of a pipe that is bent from the beginning, thus having a homogeneous thickness and not containing any plastic hardening. The Elbow element is a calculationally cheap element, specially developed for accurate calculations of pipe bends in an initially virgin state.The goal with the thesis work is to get a better picture of what happens to a pipe as it is being bent, how this affects the mechanical properties and to evaluate the possibility to develop an easy method for taking these effects into account when using the Elbow element.This report describes the layout of the work and how the detailed FE-model has been constructed.

In today?s society it is not uncommon for people to move across borders. We are more likely to work and study in other countries, initiate cross-border relationships, acquire property in other states and change our residence. Therefore it is not uncommon for a per-son to leave inheritance in several states. The laws of succession differ between countries which creates an uncertainty among the devisors when planning their successions.

The object of investigation in this essay is the epic novel sequence Jernbanan written by Sara Lidman. More specifically the investigation takes on the idea of a ?sam-vett? as it is formulated in Jernbanan. The ?sam-vett? is an idea about the undivided unity of man, nature and animal, and with a kind of primitive trait.

The purpose of this investigation is mainly to study if pupils have enough knowledge concerning the water cycle and the life of the plants?, and what kinds of household word they have, to discuss pollution within these areas. I also studied how the pupils? knowledge are holding up against what the course-plans says, since it have come to light by other investigations that knowledge are insufficient within the nature-oriented (No) subject in school.The survey has carried out on 28 pupils in a 5th grade, with help of a questionnaire survey. Their teacher has been interviewed and I have studied their local course-plans and also the pupils? schoolbooks in No.The result of the questionnaire survey indicates that the pupils had insufficient knowledge within the areas of plants? life and pollution, something their teacher had a presentiment about.The conclusion is that they need to go out more often in the nature and see how the plants and the environment are affected by different factors.

An increasing number of peole are resisting the attraction of living around nature and opting instead to spend their lives in cities. Parks and green areas play an important part in our well-being and we become fascinated with the diversity of nature, in which we find a peacefulness that is unique. Amongst other things, being surrounded by nature can reduce high blood presure, lower the production of stress hormones and stimulate the mind and our ability to concentrate. It is therefore vitally important to entice city residents to parks and green areas to improve their physical and mental well-being. Previous research has shown that humans are seeking for certain characteristics in the parks and green areas which they are visiting.

In recent time, agile methods have been devoted much attention, and the concept is widely used in the IT industry in particular. An increasing number of companies are interested in this way of working. The following report is the result of a study on the ability to create value for customers in business development through the use of agile methods. We ask what the advantages and limitations of agile methods are in the creation of customer value. Grounded Theory and an initial literature review was used to answer this question.

The area around the stream Orsundaan, which runs trough the valley Harsbacksdalen, is famous for its beautiful landscape. The upper area of Orsundaan and Harsbacksdalen is situated just south of Heby in Uppland, Sweden. Even though the area is protected by different nature conservation acts, it is difficult to find any information about the geodiversity in the area. Geodiversity, or geological and geomorphological diversity, includes the concepts of geoprocesses and geoelements. Very high geodiversity could be seen at an inventory of the geomorphology in the upper area of Orsundaan and Harsbacksdalen.

Local participation in nature conservation has gained more attention over the last decades due to international conventions as well as local and national initiatives. This development can be seen as a reaction to a more expert oriented nature conservation characterized by centralized control and strict preservation of so called "original" nature. The overall objective of this thesis is to contribute to research on new forms of conservation where democracy and local participation is included. The case study focuses on the process of producing a pre-study for a suggested national park in southern Jämtland in the Swedish mountain region, and aims to investigate to what extent local participation was included. The pre-study was led by the Swedish Environmental Protection Agency (SEPA) and the County Administrative Board (CAB) in Jämtland.

About 29 000 different services was given by the Swedish welfare state to children with disabilities within the ages 0-22 years before October first in the year 2008. Studies about children with disabilities and their experiences of their situation have rarely been done and it is therefore difficult to know how they think and feel about their lives. Both Swedish law and the UN:s convention about children?s rights states that children have the right to tell their opinion in matters that are of their concern. Thus, we don´t know much about if and how the Swedish welfare state maintain this right towards children with disabilities.

Semi-natural grasslands are threatened biotopes in the landscape and without conservation measures high values of nature will be lost. Meanwhile, the biological values associated with cultural values of the traditional agricultural landscape in Sweden. Studies of land use history may help to understand how today biological diversity has evolved and how it can be preserved. Färsna farm in Norrtälje has left some of the old heritage of biological diversity in the form of nature - forest and grassland, which hosts an unusual herb-rich flora. Through the study of historic maps and från1673/1767/1801/1901 1952 and orthophoto of the area has a picture of how land use has changed over time emerged.

Animals in zoos live in more barren environments than their conspecifics in nature. In nature, elephants spend more than 75 % of the day foraging and have been observed lying down two hours during night. Stereotypies are common in many different species in zoos. Stereotypic behaviors may constitute up to 50 % of the daily activity budget of zoo elephants. Modern zoos try to reduce stereotypic behaviors by means of environmental enrichment.

The use of out-door pedagogy in the school has been frequently high-lighted during recent years. To which extent out-door education was practised in the school depends on the opinions among the active teachers. The aim of this study was to examine the opinions on out-door pedagogy among teachers in classes 4-6 of the elementary school and to find out to which extent the teacher used out-door teaching. The study was based on qualitatively structured interviews with 4 teachers having different lenght of teaching experience. The results of the interviews showed that the teachers had different opinions on the definition of out-door pedagogy.

The purpose of this essay is to analyze and show possibilities how a city can grow into the scenery of a oak dominated landscape and how this encounter can add values to the city. The city in focus is Linköping, a city that is approaching one of Sweden?s largest oak dominated cultural landscapes. To this landscape high ecological and cultural values are connected. The recreational values are also of importance especially because of its urban location also because the city is mainly surrounded by flat agricultural land.

Due to the political system in Vietnam, all organizations in Vietnam need a permit to operate in the country and consequently, have to balance their mission, their main purpose of being in the country, with the fact that they are dependant on the government to give them the permit they need to stay in the country.With this as our basis, the main focus of this essay has been to identify different types of relations that exist between the Vietnamese state and International Non Governmental Organisations (INGOs) in Vietnam. Since we have interviewed people representing INGOs, our result is based on their experience of this relationship. By using Najam's Four-C's Model, we established that the more traditional INGOs which principally provide services, predominantly have a cooperative relationship with the state, whereas radical INGOs which are committed to policy change, mostly have a relationship which is characterised by conflict..

Dissertation in political science, D-level by Niklas Andersson, Spring Semester 2010. Tutor: Malin Stegmann McCallion?Societies in Crisis ? When Washington Take Over?An economic meltdown wreaks havoc on the world and has plunged the Western world into a spiral of economic stimulus in order to keep their way of life intact. At the same time the same institutions that support these countries have had another agenda for more unfortunate and less influential countries where nothing has been free and everything been to a price of self-sacrifice in order to get the consent of the IMF and the World Bank. Everything according to the points stated in the so called Washington Consensus.The purpose of this dissertation is to research what impact the Washington Consensus has on the state in terms of power over the market and sovereignty.
