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.

AbstractTitle: Network communication for equal opportunities (Nätverkskommunikation för jämställdhet)Number of pages: 47 (54 with enclosures)Author: Hillevi GoodTutor: Ylva EkströmCourse: Media and Communication Studies DPeriod: Spring Semester 2007University: Division of Media and Communication, Department of Information Science, Uppsala UniversityAim: The aim of this essay is to study the possibilities to bring about change by the means of communication in two networks, focusing on the implementation of the Swedish Equal Opportunities Act.Material and method: The study draws on data collected in an electronic survey among representatives of two networks consisting of representatives from trade unions and employer?s associations. The material is analyzed using descriptive tools, cross tables and correlation matrices in which general characteristics as well as individual understandings of the network communication are presented and discussed.Main results: The general results indicate that the network communication serves important purposes, such as providing support and motivation for the members and changing attitudes towards equal opportunities. The analysis suggests that the network members have good communicative possibilities to serve as agents of change within their organisations. Moreover, there is an observed relation between, on the one hand, organizational context and, on the other hand, the network members? own communicational behaviour and their experienced possibility to influence their organizations.Keywords: network communication, diffusion of innovations, behaviour change, Equal Opportunities Act.

The purpose of this research has been to investigate possible reasons for why honour related oppression exist in Sweden as well as to find out how some voluntary organisations work to change honour oppression related attitudes. The questions that the reserachers were trying to answer were (1) What are the possible causes for honour related oppression in Sweden? (2) How can honour related oppression be identified? (3) What are the voluntary organisations doing to change these attitudes? To answer these questions a qualitative method was used. The reserachers examined what leading researchers in this area thought were the reasons to why honour related oppression exist and then carried out interviews with participants from four voluntary organisations. A social constructional approached were chosen as the theoretical framework for this research and the results were also analysed from several perspectives.

Lean production is the name given to Toyota?s Production System (TPS) by the west. The continuous improvements of their operations through Lean has made Toyota into the largest car manufacturer in the world. This, in turn, has led to several studies regarding both Toyota and their system as to find ways to apply Lean in other organizations. Even so, over 90 percent of all companies fail to implement Lean.

This thesis, titled ?Change, choice and conditions?, is written by Lina Skantze and Bianca Zandén. The study explores the process in which individuals? attempt to end their criminal career, focusing on the interplay between path of life, choices, and conditions. The method is qualitative, and the empirical material consists of interviews with four young adults that all have experience of criminality.

The focus of this essay is on a political party that was founded in Sweden in 1904. Today, we known it as Moderata Samlingspartiet. Historically, this party has transitioned through multiple phases which have included a change of name and also a change of substance in the area of trade policy. The party that was cheering globalisation at the 2006 congress had its roots in protectionism and had been founded as a strict protectionist organisation. The question raised here is what has caused this dramatic change in the trade politic?In addressing this important question, I have used both organization and party strategy theories to identify the main underlying reasons.

The aim of this study is to find a method to incorporate the energydemand of a building in the investment cost estimate.The study is based on an actual apartment block. The significant energyaspects are identified, and changed to more energy efficient options.These are then simulated using the energy calculation program VIP+.The calculated energy need is used in the investment cost estimate, andthe simulated alternatives are compared in regards to their economicalprofitability.Depending on the focus, different alternatives are the most advantageous.Since this study aims to show which alternative is the mosteconomically profitable, the annual profit is the parameter of mostimportance. This means that individual measuring of heating and hotwater use is the recommended change of the original house. A changeof the windows to new ones with a U-value of 1,0 as well as 0,8W/m2K also results in a positive change of the annual profit comparedto the original house..

It's an everyday experience shared by many that nature can be of help in relieving pain, reducing stress, support mental recovery etc. In the last three decades or so this experience has also found support in a large number of scientific investigations. Among other things the experience of nature has been shown to reduce stress and pain in patients and to boost concentration and reduce impulsive behavior in children. Most of this research however has mainly been concerned with the visual modality. In this thesis the aim has been to focus on the auditory modality in this context by trying to reveal some effects on people from the exposure of nature sounds played indoors in three different environments: a grammar school class room, a kindergarten play room and a post-surgery wake up room at an intensive care unit.

Problem: How is management accounting change understood via the duality perspective in the field of alternative management accounting research?Purpose: The purpose of this essay is to develop a tool for analysis aspiring to provide understanding for how differences and similarities with regards to the duality perspective may have different consequences for understanding management accounting change.Contribution: This paper aspires towards a theoretical contribution through an in-depth review of existing conceptual literature. This is done to gain clarity in definitions and uses of concepts, with related terms, referring or relating to duality. Through clarifying different meanings of duality, consequences for how to understand management accounting change, and the different approaches to using a duality perspective, the tool for analysis which is developed in this essay aims to contribute to a movement of alternative management accounting research towards increased comparability as well as increased insight into how management accounting change is currently understood through this type of research.Method: Literature reviews based on Booth et al.s SALSA-framework. Creation of a tool for analysis for usage when reviewing material based on a duality perspective.Conclusions: The duality perspective differs, and affects understanding of management accounting change, in accordance with the following five themes:Theme 1: The duality perspective is affected by differences in the use of definitions/descrptions.Theme 2: The duality perspective is affected by different purposes of the agent and different credit given to the agents power/ability to alter change.Theme 3: The content of the duality perspective is affected by the existence and purpose off being inspired by different theoretical approaches.Theme 4: The duality perspective affects the idea and understanding of the form and expression/process of management accounting.Theme 5: Different duality perspectives have the ability to lead science against increased pluralism and/or synthesisIn order to increase understanding for and comparability between scientific contributions through a duality perspective there is to some extent a need for more and better definitions and a more problematizing when combining theoretical approaches.

The spread of digital photography has created major changes in the previously stable Swedish photofinishing market. We investigate how companies act to survive in the face of technological change, through our research question: What strategies have actors in the photofinishing business chosen during the changeover from analog to digital photofinishing? Using a deductive method, we have conducted semi-structured interviews with 11 actors in the photofinishing business. Innovation management studies innovation from a number of perspectives, describing effects of innovations on the competitive ability of established actors, and on the value of their resources. The companies were not prepared for the speed of the change.

Background: Children in our present society spend more time sedentary, and food has become more accessible.

Aim: The aim of this study was to describe the nurse?s care of obese children.

This report is a degree project performed at Freudenberg Household Products AB, (FHP). The degree project comprises measurement and analysis of the power net at FHP Basproduction. The content is divided between one theory-part, one document- part with measurements and also conclusions and a list of measures to be taken. During the project the purpose and restriction change from a quality investigation to only concentrate on harmonics and finding the reason why they exist, and also to find a solution to the problem with harmonics. The measurements shows that the power net contains harmonics of different order and intensity.

This study focuses on the development of methods for sexual determination of human skeletal remains, mainly between the years 1981 to 2007. By comparing an older analysis from 1983 (Persson and Persson) with my own on the same material, a difference of 40% was shown, which indicates that the methods has changed through time, and that these should not be used for newer conclusions about a population if the method is not throughoutly described.The main cause of the difference was identified as a change in the reliability of the sexual indicators, rather than a total change of method. Any general tendencies did not show, it is however considered that the pelvic bones are able to make a better conformity between the analyses as opposed to using the cranium..

The aim of these two studies was to investigate the possible physiological, behavioural and emotional changes that appear after human-horse interactions and also to find an explanation to why they occur. One aspect that is discussed is whether the wellbeing of humans can be coupled to interacting with horses and of how the animals respond to the interaction. The first study was performed on 9 horses and their owners, both parts being subjects to registrations during 4 different interaction treatments. The second study was performed on 6 horses with registrations only being performed on the horses during 2 different treatments. Nine horses underwent 3 different treatments all performed by their owners (H = stroking of the horses forehead, B = brushing and M = stimulation of the withers) in addition to a control round (K). Each treatment lasted for 4 minutes but observations were performed until after 45 minutes from start.

All companies face risk in their daily business. Internationalised companies tend to experience higher risk due to for example unfamiliar business environment than companies that act only on the national market. Estonia became independent as late as in 1991 and is therefore a new interesting market for many companies in neighbouring countries like Sweden. Risks that are most apparent for an internationalised company are political risk, currency risk, capital and interest rate risk, business risk and credit risk. Our intention of this study was to find out how Swedish companies acting on the Estonian market faced the different risks when entering the Estonian market and how they value the risks today.
