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.

The purpose of this thesis is to see how small differences in a store can affect the customer behavior. The changes consist of auditory and visual sensory cues. Since many companies today makes a lot of changes in their styling element, but without knowing how it really affects the customer behavior we thought it would be interesting to see by doing an experiment at IKEA. The study is therefore based on a quantitative research method, where theories have been described and from which hypotheses have been derived to test the theories. The experience took place at IKEA during two weeks where 5732 observations were made.The result from the experiment is that the sensory cue sight makes individuals spend more time in the environment but not creating attention.

This study examines implementation from national law in to local practice in the district of Kalmar to assure newly arrived immigrants orientation in civics. The study takes its starting point in Lipskys theory about street-level bureaucracy.  Questions that are discussed are about how  the education is understood by refugee?s coordinators, civic communicators and the new immigrates, how the organization has been and what role the demography and economic structures has played for the organization. It is a case study where interviews and enquete has been used.

Nature is in many ways considered a source to both physical and mental health among people. Trends in today?s society reveal that children become more distanced to nature. Seen from the perspective of sustainable development this trend is considered crucial: it is of importance that children in their early ages experience nature positively in order to develop a dedication towards environmental issues as adults.The purpose of this study is to investigate how teachers use outdoor learning as an educational tool. Research data were collected through a series of interviews.

The annual demands for forest fuels increases in Sweden. At present, large unutilized biomass resources is found in young, dense forests from which about five million oven-dry tonnes (ODt) (23 TWh) could annually be extracted as forest fuel. But harvesting small trees give high logging costs and new cost-efficient harvesting techniques are therefore required. The aim was to study the productivity of Vimek 608 BioCombi in forest fuel thinning of Lodgepole pine and to calculate the economy of the harvesting and estimate the thinning quality. The Time study was performed in Åmarken in the county of Västerbotten.

This study in political science examines the UN adopted resolution 1970 (2011) andresolution 1973 (2011) on the basis of foreign policy decision-making. The study aims toexplain how the UN principle of Responsibility to Protect came to be legitimized for the firsttime by the UN Security Council in the Libya conflict in 2011. By a poliheuristic perspectivethe study attempt to explain Russia and China?s acting in the voting of resolution 1970 andresolution 1973. The background to the conflict in Libya 2011 is presented in the study aswell as the Security Council?s actions during the conflict, from the beginning of the conflictuntil the adoption of resolution 1973.

The purpose of this thesis was to help the company Medius AB with optimization of selected parts in an existing system to minimize the execution time by implementing multithreading. The idea was to manipulate the code so that calculations could be executed at the same time. The main work in this thesis consisted of three optimizations. The first one was to reconstruct a big ?for-loop? so it would execute every loop's work in an own thread. The second optimization also was a reconstruct of a ?for-loop? so it could execute the work in different threads. The third and last optimization consisted of reconstructing a stored procedure on the database, so different parts of it each could be executed in an own thread to create data at the same time. To implement the optimizations Visual Basic .NET and its support for multithreading and connection-pools was used. The result of the optimizations meant that one of the modules could be executed more efficiently and it was 12 % faster. The other modules execution time was more efficient by 25 % faster. The meanings and requirements for this thesis are fulfilled by now letting the system make use of its resources in a better way..

AbstractThe purpose of this study was to increase the knowledge of teenage girls thoughts and opinions about narcotics. We used a qualitative method and collected information by interviews. During the past years different studies shows that the desire to try narcotics has increased among teenagers. Teenagers are trying hard to find their identity which is shaped among people that they have a close relationship to. During this time friends has big influence when they experiment with different kind of styles.

The purpose of this study is to use a qualitative method to investigate the Swedish curriculums of 1919, 1962 and 2011 in search of attitudes and different usages of the popular culture of the time. To reach these conclusions Antonio Gramsci?s theories about cultural hegemony have been applied to prove how the superior classes, in this study these classes are represented by the Swedish school as an institution, use popular culture to maintain sovereignty of the lower classes. Ergo the problem highlighted in this study is whether the cultural class society exists in a fixed state since the 1919?s with the school as the institution to implement the tradition of cultural hegemony.

Simulation of different systems can be done using a graphical model description of the system based on block diagrams. The simulation software Matlab/Simulink offers a lot of possibilities to describe a huge number of systems, which can be linear as well as nonlinear. The simulation using Matlab/Simulink is done by integration based on different kinds of numerical methods.When nonlinear Simulink-models are simulated, it is often interesting to apply a Kalman filter to handle the noise that may occur within the process as well as corrupting the measurement. However, application of such a filter leads to an extensive time-consumption despite using fast computers. The reason is that the existing Matlab functions are not constructed for time optimal evaluation.

The Transport division is responsible for the internal transports on Sandvik MaterialTechnology AB. At the moment there is no clear picture of how the straddle carriers aremoving at the division Primary Products and if it is working in a satisfying way. It isimportant to see the whole picture of the transportation flow so improvements can be made.The purpose of this essay is to survey and analyse the truck flow in a Lean Productionperspective. The essay is delimited to only include straddle carriers transportation ways in thePrimary Products division. To survey the truck flow we have used a method called Walkthrough.This means that we have walked thorough the whole production flow andinterviewed some of the employed on the way to get the necessary information.

Background: Enterprises often refer to their employees as ?Our most valuable assets? in annual reports and other written statements. In reality, employees are seen as an expense rather than an asset in annual reports and the voluntary disclosure is often insufficient. Human capital disclosure has been discussed through decades and the latest topic in voluntary disclosure is called integrated reporting. Knowledge firms should disclose more about their employees than industrial companies due to the fact that the employees are a considerably more important asset to these types of enterprises.Purpose: The purpose of this thesis is to study the disclosure of human capital, compare the disclosures between knowledge firms and industrial companies, and study the development of the human capital disclosures between the years 2003-2013.

 The aim of this study was to examine how young people, who have been treated for their misuse and/or to learn to handle a parent's misuse, portrayed the network's implication in their wishes about improving their lives, to make new choices. The network included members of nuclear family, relatives, important persons at school/work and friends. The ?professional network? (therapists and social workers) also became a part in the young people's life during a period. The main issues of this study concerned differences in their experiences of the young persons´ network relationships in before, during and after completed treatment.

The study aimed to capture the institutionalized adolescent´s life stories and identified their thoughts and experiences of being institutionalized. This to understand and analyze the process that they go through to become adults with respect to three selected aspects: family relationships, school attendance and self-esteem. The adolescent´s in this study are or have been institutionalized by and according to Swedish law. It was based on 14 life stories and the purpose were to identify the adolescents thoughts and experience and which was later on used to understand and analyze the results with respect to the three selected aspects. Our analysis was based on two theories; symbolic interactionism and labeling theory.

Today?s society has become more and more digitalized and we have access to more information than ever before. This has had a major impact on organizations and their work processes. For example have intranets become a common technical groupware to communicate and get relevant information from inside the organization. A common problem related to this is an over-reliance on the technology, where there's not taking into account that some informal and communicative means are difficult to occur through digital resources.The aim of this study is to examine the use of an intranet in a municipality, which consists of many different employees with various work situations.
