The LSH-study started in 2003 at the department of Health and Society at the University of Linköping. The purpose of the study was to examine the relationship between life condition, stress and health. A total of 1007 people from ten different health centres in Östergötlands län participated. At the follow up, a couple of years later, 795 of the 1007 participated. 127 of the 212 in the attrition turned down the follow up, twelve people were not invited (for example in case of death) and the rest did not respond at all.

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.

This essay is about the tactical basic principles as they are mentioned in the Swedish Doctrine for land based operations (2005) and the German side during the battle of Verdun 1916. The purpose of this essay is to clarify whether the used doctrine is appropriate to use on future attrition battles.        This is done by a case study of the German side during the battle ofVerdun. In this case study indicators of the basic principles are then identified and analysed with the starting point at the two questions that the essay is based around. The essay starts with an introduction where above is attended, in the second part the basic principles, the background to the battle and the battle itself is described. Finally the tactical basic principles are analysed and discussed based on the questions that the essay is based on.In the analysis and the discussion the conclusion is drawn that the tactical basic principles were present on the German side during the battle of Verdun and that they are of a general character and may be applied on both attrition warfare of 1916 and modern battles of attrition..

Syftet: Målet med studien var att utvädera kliniska intraorala foton som diagnostisk metod för att bedöma tandslitage (attrition, erosion och abrasion) och jämföra dessa bedömningar med kliniska registreringar. Material och metod: Studien genomfördes på Tandvårdskolan i Malmö, där man slumpmässigt valde ut 30 vuxna patienter. Dessa patienter undersöktes med avseende på tandslitage (attrition, erosion och abrasion) och kliniska foton togs. En månad efter kliniska registreringen gjordes en bedömning av de kliniska fotona, utan att ha kännedom om resultatet av de kliniska registreringarna. Båda undersökarna har på samtliga patienter utfört klinisk registrering och fotobedömning oberoende av varandra. Intra- och interobservatör överensstämmelse uppskattades genom Cohen?s Kappa- koefficient. Resultatet: Intraobservatör överensstämmelsen mellan bedömningar av foton och kliniska registreringar var måttligt-till-god med ett P-värde på 0,039-0,046.

This survey is a qualitative study about how teachers see on the concept student leverage and what they say about how they in practice work with it. We have chosen to examine the subject from a teacher?s perspective, because almost all investigations and literature, that we have found, discuss student influence from a student?s perspective. That?s why we are interested to examine what teachers think of the subject.

Soldater som avbryter sin grundutbildning i förtid innebär onödiga kostnader och åtgärder för såväl organisationen som för de enskilda berörda. Försvarsmaktens mål är att avgångarna inte ska vara högre än 7 % av inryckande värnpliktiga. Målet har dock varit svårt att nå och för åren 2000-2005 ligger de genomsnittliga soldatavgångarna på cirka 13 %. Skillnaderna i avgångstal mellan olika förband är dock stora och den här undersökningen studerar om det kan bero på det ledarskap som praktiseras vid förbanden.Genom att mäta nivån avseende utvecklande ledarskap, vilken är Försvarsmaktens ledarskapsmodell, vid sex arméförband och sen koppla ihop den med storleken på deras soldatavgångar identifieras olika samband. Därigenom framgår också faktorer som är viktiga för att nå låga avgångar.Resultaten pekar mot att det finns samband mellan storleken på soldatavgångarna och nivån på det utvecklande ledarskap som tillämpas.

Sammanfattning Tandslitage är ett vanligt förekommande problem. Det finns olika typer av tandslitage såsom attrition(fysiologisk), erosion(kemisk) och abrasion(mekanisk). De bakomliggande orsaksfaktorerna skiljer sig åt för de olika typerna av tandslitage. Attritioner delas upp i normalt och patologiskt. Normalt tandslitage beror på ålder och kost, medan patologiskt tandslitage som även kallas bruxism, kan orsakas av stress och oro.

The importance of student influence at the universities is something that is described in Swedish regulations as well as in local policies and documents for Karlstad University. At the same time there is no description for the interpretation of what student influence actually means. It is up to the university to decide what student influence should be at the university and how it should be represented in the organization and processes.The purpose with this essay is with a discursive perspective of analysis define how representatives of Karlstad University reflects how the student influence should be represented in the organization and if it is possible to connect it to the position as an actor of co-decision or of influenceThe analysis show that different levels of the university will describe the position of student influence differently, and that it plays different roles to keep up the quality of education at the university. It shows that it will be of more importance that student influence takes the role to influence the organization more than co-decide the nearer the student the process will come..

The purpose with this study is to gain understanding about student´s view of mathematical education, in the later years of nine-year compulsory school, and the motivation factors that can be identified when student´s gives opportunity to express their own thoughts due to the mathematical education. From experiences we have gained during the practical part of our teachers education we got the impression that student´s think that the mathematical education is boring and uninteresting. Through qualitative methods such as survey and discussions in focus group we have analyzed student´s views of mathematical education and pointed out witch motivation factors that are expressed when student´s gives opportunity to influence over their own education. The results are shown from the answers and comments that student´s gave, during the survey and focus group, and is divided into two main parts, both with focus on motivation ?Mathematics and motivation? and ?Student´s influence and motivation? and also a summery part ?Motivated for mathematical education when the student is given influence over the education?. The study showed that student´s wants to have more difference in the work methods that are used in their mathematical education such as problem solving, games, more work in groups and pairs and more use of IT. In conclusion the study also gives suggestions to other studies that can be made in the same genre as this study in the way that IT can be used in mathematical education and how student´s interest can be used in the education to gain more motivated student´s..

This study is based on interviews with six students from Stockholm that have shared their feelings/opinions about how they experience their identity as a student. The aim of this master?s thesis is to examine how the identity of students is constructed but also how the post modern society affects the life that the students are living. With a higher demand on education and responsibility of making the right decisions, the student?s main concern is not only her studies, but also the goal to succeed in her life.

The purpose of this thesis is to determine whether the student councils at two schools really have the power to influence, or if it is a matter of mock democracy. I wanted to determine how the student councils work in reality. I conducted my investigation through personal and qualitative interviews with the board of the student council, a social studies teacher and the principle/school management at both schools. After the interviews I compared an analysed my findings. The results show that the two schools work very differently when it comes to studentdemocracy, and even have very different levels of ambition when it comes to the degree of influence that the student council should have at their respective schools.
