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.

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 topic of this essay is the strategic importance of the Golan Heights during the period 1967-1973, specifically targeting the following questions;-          Why were the heights strategically important?-          What are the gains of either of the states in controlling the Golan Heights?A theoretical framework based on Jerker Widén´s and Jan Ångström´s Militärteorins grunder (The fundamentals in Military Theory) and its chapter regarding the strategic context will be used as an analytical framework.The framework has been applied on the specific conditions of the Golan Heights during a given and limited period of time; stretching from 1967 to 1973, however, the study will not deal with the war of Attrition in 1970 as the impact on the Golan Heights and the surrounding geographical strategically important area was limited if at all. The two wars waged during this particular time are used in an attempt to give a somewhat objective picture of the strategic importance of the area.The conclusions are that the importance of the Golan heights during the selected period was significant as the Golan Heights provided a ?strategic lock? both ways and provides a favourable area to deploy artillery, intelligence and surveillance sensors..
