The purpose of this work is to design and construct a device able to measure the mechanical attrition of oxygen carrier particles. Those particles are used in chemical looping combustion and in the present situation there is a lack of knowledge in how the attrition process work and in which extension. To find already tested solutions trying to answering this problem a literature study wascarried out and the best solution found was the so called Grace-Davison Jet-Cup method. This method is supposed to emulate the attrition caused by a cyclone separator and its advantages are that it is possible to use small test amounts, 5-10 g, and a thirty minutes long test will be enough to acquire useable results. An device was designed based on the Jet-Cup method with some slight modifications.

There is always an endeavor to govern the initial products in the plant cultivation with precision in order to keep down the expenditure and in order to decrease environmental impact. Initial phosphorus fertilizer can then be one possibility in order to keep down the fertilizer cost and to decrease environmental impact. This exam study includes a literature study about location of fertilizer and which effects this give and two field experiments. The aim with initial phosphorus fertilizer to autumn wheat is to accelerate the root growth and to give the crop a big root system before the growth stagnates before the winter. Easy to access phosphorus favours the root growth.

This thesis concentrates on the organization surrounding the school transports in Norrköping and its surrounding areas. It is a qualitative research based on interviews with four different groups that is included by this organization, local municipal officials, entrepreneurs, school personnel and youths depending on this service. I have used organization theory as a theoretical base. In my study it became clear to me that this is a complex and multifarious organization. The many different actors sometimes make it hard to survey all the different parts of the organization.

Vaccination as a part of the preventative public health project has for many years been one of the important tasks of the children's health care. The vaccination program has been adjusted to current research and the health situation in the country. Having their children vaccinated is not something obvious for all parents, though. Especially the vaccination against measles, whooping cough and German measles have been questioned. The purpose of this literature study was to investigate the reasons for the resistance to vaccinate and to illuminate the security creating advice of the nurse at the public health centre.

AbstractInterest in the subject appeared from real events. We seemed to discern a trend in society. Wehave noted that the amount of social enterprises to a greater extent is formed in Sweden.Companies like GodEl, Postkodslotteriet and DEM Collective are typical illustrations ofcompanies included in the category of social enterprise. It seemed as socially profiledcompanies is the new generation companies. The purpose of this essay is to make aninventory of possible competitive advantages that arise from social branding.

The aim of the study is to elucidate and analyze newcomer students´ experiences of the Language Introduction Program, in more detail, how the students describe their time at the program and how experiences could differ between girls and boys. Finally, the study examines how the program, according to the students, can be significant for their future. The analysis of the students´ dictums is based on the perspective of intercultural education. To answer the study´s aim and research questions, the investigation consists of eight semi-structured interviews with students who are studying at the Language Introduction Program at an upper secondary school in Uppsala.The results show that the main advantages with studying at the Language Introduction Program are, according to the students, that they learn the Swedish language and that they meet students with several cultural backgrounds. The main disadvantages that were noted were that the Language Introduction Program takes a long time to finish, and furthermore, the contact with the students at the other programs at the school is not enough.

Peat litter has been used in animal houses for a long time. Because of its good ability to absorb liquid and nutrients from the manure it can create a dry surface for animals and a valuable manure product. Through changes in agricultural practises the use of peat litter has diminished and is to a great extent replaced by straw, sawdust and cutter shavings although Sweden is rich in peat-findings. The aim of this work was to summarize the presented knowledge about the used of peat litter, techniques, advantages and disadvantages and to compare with other commonly used litter materials. Articles on peat litter have been searched for in magazines, databases and books at SLU library. Visits to peat industries, interviews with peat producers and with peat researchers contributed to the material. Peat is not a uniformly material.

The xenophobic attitudes in Europe are stronger than even. Never before have the member states had as many right-wing parties in action. The aim with this report is therefore to consider whether the Schengen cooperation has had an influence on the development of xenophobia in the member states of EU. The Schengen cooperation became a part of the European Union in 1997, with the aim to abolish the internal border controls for citizens and strengthen the external boarders towards non-members. The intention is furthermore to investigate whether the distance to Schengen ?s external boarder has an impact on the xenophobic attitudes.Three countries are compared: Italy, Netherlands and the United Kingdom.

Trots att stress tidigt i livet kan leda till ohälsa i vuxenlivet finns det förhållandevis få studier av psykobiologiska aspekter av stress bland ungdomar i Sverige. Syftet med denna studie var att undersöka sambandet mellan självrapporterad stress (n=412) och salivkortisol (n=278) hos friska skolungdomar i årskurs 8 och 9 i två Stockholmsskolor. Vidare undersöktes könsskillnader och skillnader mellan årskurser i självrapporterad stress respektive salivkortisol. Data samlades in via ett självskattningsformulär som mäter generell stress samt genom salivprover tagna vid fem tillfällen under en dag. Resultaten visade på ett signifikant samband mellan självrapporterad stress och salivkortisol (r=0,29) vid en tidpunkt.

Throughout this thesis three main factors have been identified that can be out of significance for transfer pricing in multinational companies if the proposal for Home State Taxation is adopted. These factors are rules for calculation of the tax base, rules for dividing costs over periods and the tax rate. The formula for sharing profits will also become a factor that can have an impact on the European companies'incentives for transfer pricing interacting with above-mentioned factors. The effects of transfer pricing aiming at reducing the total amount of the taxation burden for a group of companies will be strongly reduced in the future if the proposal is adopted. Incentives for transfer pricing will loose importance, though not disappear altogether.

Nowadays Wireless LAN is playing a more and more important role in network systems. After 1999, in which the IEEE organization published its Wireless Local Network standard 802.11[1], many people saw the advantages of the standard but also the lack of support for multimedia streaming. A lot of research work has been done on the proposed IEEE 802.11e standard draft during the past 4 years. It is supposed to be able to fully support Quality of Service. The final version will be published early in 2004.

There are many children in Sweden today, approximately between 100 000 and 200 000, who have parents or a parent that abuses alcohol or other drugs. In this research paper we have reviewed some of the literature concerning these children and their situation. The purpose of this research paper was to make an interview study of a group activity for children that have parents or a parent, who abuses alcohol or other drugs.This research paper is based on interviews conducted with two children and four group leaders. We compared the children's opinions about the group activity to the opinion of the group leaders of what the group activity has given the children. We also wanted to compare our interview study with other similar studies that has been made within this subject.
