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.

If Sweden want to be able to compete internationally with its production capacity,it is important to work actively with production development and production ofresource-and time-efficient. This report is a bachelor thesis of 15 hp conducted atthe University of Halmstad. Using the principles of continuous improvement andLean Production, the author developed a concept for HAGS Aneby AB to changeto the customer order driven assembly of spring toys.First of all, the theories of Lean Production, logistics and ergonomics are used tobuild and present a theoretical framework for further examination. Then, toachieve the target, the current assembly process is analyzed to develop some firstconceptual ideas for improvement. In order to develop the best advice, theconcepts are evaluated against the company?s requirementsThe developed action plan gives recommendations on how the company shouldrestructure their assembly process and the organization of the related departmentin order to produce spring toys in a more time efficient and lean way.

This paper studies the relationship between individual characteristics of displaced workers and the probability of re-employment. A competing risks hazard model is used, distinguishing between exits from joblessness to self-employment and to paid-employment. All individuals between 25 and 55 years of age, at the time of displacement, that suffered from at least one year of joblessness after being displaced between 1990 and 1998 due to establishment closures that occurred between 1990 and 2001 are included. This allows for the closure procedure to be between one and three years long. Each individual is followed, from the year of displacement until the year of re-employment or at the latest, ten years after displacement.

Individual adaption to the student´s needs is a recurring main theme in the new Swedish curriculum (Lgr11). The purpose of this qualitative study is to examine how teachers work with individual adjustment for students with reading and writing difficulties. The study was based on five questions;In what way do teachers organize their teaching in the classroom individually for students with reading and writing difficulties?What methods do they use for student´s with reading and writing difficulties?What difficulties do they encounter in their teaching?How do the teachers reason to curriculum goals regarding individual adaptions?How do they think about their own knowledge regarding reading- and writing difficulties and dyslexia?The method for my study was qualitative interviews. Five teachers were interviewed in semi-structured interviews.

This study aims to examine how teachers in elementary school reason about and effectively implements special needs education. A qualitative study was made by interviewing four elementary teachers about their own role in dealing with pupils in difficulty. The material was then analyzed using content analysis. The result section is presented by the study's issue and then been analyzed against the background research. In the analysis it follows that the teachers believe among other things that there is too little time and resources to meet pupils in difficulty, the time and resources in schools is essential when it comes to meet students' needs.

The general view of learning has dramatically changed during the last two decades. Today we talk about learning for life and educate to meet the demands of the information society. This new view forces us to constantly relearn and develop new knowledge ? something which has resulted in large restructuring within the upper secondary school. New forms of teaching, where the pupils are given the opportunity to a more active search for knowledge, is developing.

Title: Why Great Britain? ? Swedish Encyclopaedias and the Explanatory Perspective of History, Essay in History AbstractIn my essay I describe how Swedish 20th century encyclopaedias interpret the coming about of the British Empire, the overall purpose being to establish a pattern of evolution in terms of historical understanding on the part of the encyclopaedic literature. Firstly, I have tried to determine whether the presentations at all constitute explanatory efforts. In those cases where they do, I have sought to ascertain whether the reasons put forward are to be understood as structural and stable, or as matters of less permanence. I have also tried to link these interpretations to significant ?constructions? of history ? i.

This master thesis was written in the purpose to study how the location and access to computers in the physical realm of the public library reflects the undergoing changes in the public libraries role in Swedish society. This study is done in a form of a case study of three small public libraries. All of them were in the process of transforming both their physical and virtual space. The thesis focuses on where in the library the computers are placed and how their location interacts with the libraries main tasks. It also focuses on the analysis of the relationship between these two elements and how that relationship reflects the alteration of the public libraries place in society.

In today's society, more and more people traveling with transports such as trains and buses. With this type of travel it often exists waiting at stations that in many cases perceives as negative. Previous research demonstrates that distraction can get people to experience the waiting as less negative. This paper aims to examine how waiting can be affected by distraction, and if it is possible to use a second type of waiting as a distraction. The authors have chosen to focus on travelers who are waiting.

KSL Trading Inc is a trading company in the Jönkoping area that distributesmaterial for the furniture and interior design industry.The purpose of this report is to analyze the existing material flow andwarehouse layout as well as to identify the issues there are today at KSL?swarehouse for board material. When we identified what kind of problems thatexisted we were able to design a new plan for the material flow and storagepossibilities. The problems we found where:? There is no well-organised warehouse layout? There are no routines to keep the warehouse clean and in order? There is no formed plan how to handle materialTo solve these problems we have used different methods like interviews,observations, calculations and literature studies.

Agricultural land could be polluted by radioactive substances after a fallout. We would then need information about the level of contamination to decide whether the crops could be utilized as food under these circumstances. In an experiment carried out during the 1990ies the retention of 134Cs in potato haulm and the transfer to the tubers were studied. The experiment was carried out during three consecutive years. The plants were cultivated in pots under field conditions and the artificial deposition was sprayed directly onto the potato haulm at different times during the growing season.

This Master s thesis deals with the display of library media, whether it is conceivable and desirable to draw inspiration from the retail business when displaying articles. The questions asked are: are there, in the retail sector, well established display ideas and - if so - what do they look like? Are the similarities in conditions, between the branches, sufficient? In conveying the ideas to libraries, are the potential differences not obstructive? Is there, among librarians, a positive attitude towards further development of library display techniques? The results were achieved by interviewing shop window dressers and librarians. In addition, a survey was sent to the library managers of 65 public libraries in southern Sweden. The results show that there are established ideas and methods of displaying materials, and that the ideas are manifested in frequently used techniques.
