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 determine how well a student is prepared as a future librarian at BHS in Borås, when it comes to serving individuals with hearing disabilities at the libraries. The theory and combined methods is that of discourse theory, interviews and Webb searches. The source material for this thesis comprises course material from 2002 and 2003, with the main focus on the spring term 2003 and on what is called the users perspective användarperspektivet. The study is divided into two parts: firstly, to determine the students expected knowledge and his/her future professional identity through this knowledge. The user groups that were mentioned to the students during the education were also linked to the students knowledge.

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.

Regarding school-teaching most people have had the traditional idea that the teacher is the owner of all knowledge and the student is the receiver of that knowledge. Tradition tells us that the way the student receives the knowledge has been by listening, repeating, reading and memorizing what the teacher has taught. Research about teaching from the last decades show that there are other strategies, ways, and qualitys for helping students in learning. One of those ways is by integration of different school subjects.According to research every human being creates her own knowledge based on personal experiences. Johan Krantz and Pelle Persson (2001) wrote that learning is a process with experiences, ideas and opinions.

Abstract Abstract The aim of this essay was to investigate the level of the organizational state of readiness for receiving students with learning disabilities in classes specialized in working with students recently arrived in Sweden, called förberedelseklasser, which could be translated as preparational classes. I tried to do so by answering two questions: *What routines do principals believe that the particular School has for dealing with cases in which a student in a preparational class is suspected to have some form of learning disability? *What perception do teachers have in regards to whether or not the system at their School is well prepared for discovering and aiding students in preparational classes suspected to have learning disabilities? The first question was directed to principals currently working in schools where a large part of the students are bilingual, and many of those recently arrived in Sweden. The second question was aimed at teachers that work in preparational classes. By interviewing two principals and three teachers I came to the conclusion that the teachers believe that their students are often misplaced in preparational classes when in deed they should be placed in a special educations group. My essay also shows that both principals and teachers are dissatisfied with the amount of time the process of discovering, investigating and diagnosing a student with learning disabilities takes.

Summary:Teenage girls? choice of dropping out or complete a treatment.The purpose of this study is to investigate, from a client?s perspective, why teenage girls (age 13 to 17) drop-out or complete a treatment at Familjehuset in Karlstad, Sweden. We also want to investigate if the teenage girls? experiences coordinate with the social workers opinion of why the teenage girls choose to drop-out or complete the treatment. Earlier research shows that many factors influence the client?s choice.

Glycerol is essential for the lipid metabolism of both plants and animals. Glycerol is formed in the rumen by hydrolysis of lipids from the feed. Glycerol is also a by-product from the production of biodiesel from rapeseed oil and other fat sources. Glycerol might be used as a dietary glucose precursor for dairy cows in similar ways as propylene glycol. Due to increased production of biodiesel more glycerol has been available to a lower price.

Purpose:To concretize the various factors on students' theses that are perceived valuable and can contribute to corporate profitability. In our investigation, we want to strengthen the understanding of a "win-win-situation" of cooperation between students and businesses.Methodology:In this study, we have chosen a qualitative approach in which five personal interviews with various organizations that are active in a knowledge intensive industry. A semi-structured questionnaire was used in our interviews.Theory:Our theoretical framework has two broad areas. Introductory chapter is based on theories of research development in Sweden with theories that emphasize the value of collaboration and knowledge. The second chapter deals with a theoretical outlook on value and how this can be applied in marketing.Conclusion:The study shows a diversity of values within three broad categories.

Syftet med studien har varit att beskriva erfarenheter av dialogen mellan distansstudenter och dialogens betydelse för förståelse och meningsskapande. Vårt empiriska material utgörs av semi?strukturerade intervjuer. Respondenterna består av studenter som vid något tillfälle har varit distansstudenter vid distansutbildningar hållna av Blekinge Tekniska Högskola. Vissa respondenters erfarenheter grundar sig även i distansstudier vid andra universitet och högskolor.

Fertilitetsegenskaper har ofta låga arvbarheter och selektion baserat på fenotyp är ofta ineffektiv och långsam. För att förbättra fertilitetsegenskaper som ovulationsmängd och kullstorlek hos får är det effektivast att selektera avelsdjur utefter deras genotyp. Olika mutationer i gener tillhörande transforming growth factor-? (TGF?) superfamiljen har visat sig påverka ovulationsmängd och kullstorlek hos får. Dessa gener är BMPR-1B, BMP15 och GDF9.

Background: Oil is the most dominating source of energy of today, it constitutes for more than 40 per cent of the worlds total energy consumption. This together with the fact that stock in oil companies has soared on the stock exchanges around the world makes oil a very interesting topic to write within. In order to gain knowledge in how to value oil companies, the authors will collect information from theory and through a questionnaire. By applying the information gathered to three companies listed on the Stockholm Stock Exchange the authors will reach an objective picture of valuation of oil companies.Purpose: To investigate how shares of stock are valuated in the oil exploring and producing industry, and what specific measures and metrics that are used in the valuation of stocks in Exploring and Producing (E&P) companies.Method: By using a qualitative approach for this thesis, the authors will investigate how the valuation of oil companies works and what measures that should be applied. The authors will use a part descriptive and part explorative study.

Vårt syfte med denna studie är att utifrån en socialpsykologisk ansats ta del av elevhälsovårdens och stödverksamhetens arbete respektive samarbete på en gymnasieskola i en medelstor stad. Med hjälp av kvalitativ metod har vi utfört sex enskilda intervjuer, en parintervju samt ett experiment. Vi har använt oss av följande socialpsykologiska teorier: Gruppsykologi (Svedberg, 2007), Det potentiella rummet (Winnicott, 1993), Ungdomstidens kriser (Cullberg, 2006), Den konkreta och abstrakta socialiteten (Asplund, 1987), Benämnandets kraft (Crafoord, 2005), Emotionsteori (Scheff, 1990). Genom dessa teorier har vi försökt belysa svårigheter med, och ge en förståelse kring, hur elevens situation i skolmiljön ser ut samt hur arbetet inom, respektive samarbetet mellan, elevhälsovård och stödverksamhet mot en god elevhälsa ter sig. Vi har i föreliggande studie upptäckt att vissa typer av problem respektive svårigheter hos eleven uppmärksammas medan andra glöms bort.

ABSTRACTToday's modern technological society is constantly evolving and house planning is one area that is constantly creating new technical solutions. By looking back at selected architectural eras during the 1900?s, the idea is to study and analyse three building structures in Gothenburg with a focus on quality and content in the urban space.In order to provide a background for the three selected areas, their history has been studied. The main question for the research is: how do different building structures affect the content and qualities in the urban space?The areas have been selected to represent three typical epochs in Swedish building history.

Ett samhällsproblem i Sverige under de senaste åren har varit antalet studentbostäder på landets lärosäten. Idag kan enbart fyra studieorter erbjuda bostadsgaranti för sina nytillkomna studenter, där bostadsgaranti innebär bostad inom 30 dagar. Byggandet av studentbostäder stannade av helt år 2010 då endast 125 stycken blev byggda. Från 2012 och framåt har trenden börjat vända och framtiden ser bättre ut men det är inte i närheten av att kunna mätta det behov som finns. Idag bor cirka 25-30 procent av Sveriges studenter i studentbostäder.

Being a student in the educational system is in itself a challenging exercise, considering the various parts that may matter in different extent for the students. There is a syllabus, there are different backgrounds and contexts for each student and there is also the knowledge in the subject to consider. This study sets out to explore to which extent teachers and students reflect about the transition from public school to upper secondary school/high school, specifically in the context of History as subject. What do they think about it and how do they work with it?By interviewing five teachers and letting 94 students in upper secondary school completing a survey about this subject (the transition), I can conclude that the matter is complex, both for students and teachers, however still a significant and important issue to discuss.
