Regulations on the exhaust emissions of HD-diesel engines are becoming more and more stringent, and therefore, emission after-treatment systems are commonly used. These systems rely on catalytic conversion of NOx,CO , and HC emissions, and are thus dependant on temperature. At low load of the engine, exhaust temperatures are not sufficient for the after-treatment components. Therefore, means to increase the exhaust temperature while maintaining low emissions and fuel consumption are needed.The focus of this project has been to develop strategies for the lift profiles of exhaust and intake valves in the engine, with the goal to raise exhaust temperature in combination with low emissions and fuel consumption. The strategies have been tested in a single-cylinder research engine equipped with a hydraulic variable valve actuation system.

The purpose of this thesis is to identify and analyse the view and consciousness of history present in essays written by Swedish high school students in 1877 and 1929. A theoretical framework was established in order to accomplish this, based on the theories of Peter Aronsson and Jörn Rüsen (through Lars Andersson Hult) that defines consciousness of history through a matrix that expresses a progression as well as a scaling complexity. Furthermore, the theories of Knut Kjelstadli and Magnus Hermansson Adler were adopted to establish two different types of view of history: one adhering to a view of history where groups and individuals are seen as integral to the progression of history, and the other explains historical process through more functional explanations, such as dependant on cultural and social structures.This framework erects ideal-types of different types of view and consciousness of history, and the thesis at hand strives to categorise the different kinds of view and consciousness of history found in the studied essays in accordance with these ideal-types through two different models based on the above mentioned theories.The findings presented here largely point to a view of history that is largely centered on an actor-oriented view of history, where individuals such as kings and generals are given a central position when historical events are being narrated, and is present in both 1877 and 1929, with some shifting nuances. As for the consciousness of history the lion part of the analysed texts can be seen adhering to a more traditional type of consciousness in 1877, although a slight shift can be seen towards a more complex type of consciousness in the texts from 1929..

Abstract    Objective: The aim of the present study was to investigate if inclinometer estimates of arm posture during paper mill work differed between periods of different arm visibility. The aim was also to identify strategies for and difficulties in assessing body-visibility on video. Methods: The study consisted of two parts, where part 1 aimed to investigate the validity of observation-based assessment of arm posture during paper mill work. Study 2 was a survey among people with experience in assessing the posture of paper mill workers from video. Results: The total time for the right upper arm visibility indicates that it was on average visible in 54%, partly visible 15 %  and not visible 31%.

Syftet i studien var att få en djupare förståelse för hur kvinnor som arbetar inom en mansdominerande industri förhåller sig till ohälsa. I bakgrunden presenteras kvinnor och mäns position i samhället samt hur kvinnlig sjukskrivning ser ut på ett nationellt och internationellt plan. Hur normer och synen på kvinnor ser ut och påverkas på en arbetsplats som domineras av män. Studier visar att kvinnor står för procentuellt högst antal sjukfrånvarodagar och att bidragande orsaker till detta kan vara biologiska skillnader.  Uppsatsen bygger på en kvalitativ ansats där sex intervjuer har använts som metod, detta för att få den djupa förståelse som studien annars hade kunnat gå miste om ifall andra metoder använts. Resultatet visade tydligt att majoriteten av de undersökta kvinnorna hade svårt att beskriva sina åsikter kring företaget.

The scarcity of qualified forest machine operators as well as the increased competition for competent machine operators among others from the mining industry in Norrland, were the reasons to investigate what attracts and what deters active and potential forest machine operators to the occupation. An interview study was conducted among four groups with four persons in each group. The groups were students in year 1 and 3 respectively at a forestry school at upper secondary school level as well as employees of a forest company and employees of contractors. The majority of all respondents were of the opinion that their interests in machines had been important for the choice of occupation. But for the active machine operators both the interest in the forest and their interest for machines have had importance for choosing this occupation.

To work in an unpredictable work environment requires communication that functions well. In every organization it?s important that employees receive information that is relevant yet not confusing. Due to that, our ambition with this study is to understand how rescue effort organizations communicate in meetings; and whether their communication is clear or not. Our subject for this case study is the Emergency Services in the region of Karlstad.

With the globalization, companies in the West chose to shift production to developing countries to cut down costs. This had a major impact when child labor and very poor working conditions in these factories were discovered and led many companies to take responsibility for their suppliers and the employees by adopting voluntary so-called Codes of Conduct.There is a subtle balance to enforce improvement of working conditions for employees at suppliers´ factories and to keep costs down. On the one hand, companies would like to conduct extensive audits at their suppliers to ensure code of conduct compliance and thus protect their legitimacy. On the other hand, audits are expensive so companies would like to minimize audits to keep costs down. Companies thus have to strike a delicate balance in relation to how many and what suppliers they choose to audit.

Our starting point has been to use the football player Zlatan Ibrahimovic as a model person for individualism that seams to break the ordinary socialization pattern in Sweden. The purpose of this study is to examine how the team leaders handle the socialization of more individualistic focused individuals/young persons into groups, since the Swedish School Curriculum is designed to meet each individual on his or hers former experiences. Is the socialization of individuals within team sports affected by their cultural background? And, in that case, should those facts have consequences for the sport subject at school? Those are the questions we want to explore. Besides a survey of documents, we have been seeking answers to our questions through interviews with the team leaders Roland Nilsson and Peter Bergander, the pedagogues/teachers Karin Jutterström and Håkan Jensgård and the professional football player Abgar Barson.Our study shows that the leaders and teachers of today have begun to change their view about individualists.

Study objectives:Examine ambulance personnel?s perceptions of skills / training and knowledge with regards to the existing mechanical / manual compressions and frequency of training during a work shift. Do ambulance personnel think that mechanical compressions increase survival? Are there concerns that the device could damage the patient?Design: A cross-sectional study, quantitative approach with qualitative elements was conducted.Methods:Questionnaire form, which was answered by 44 ambulance personnel in an ambulance organisation in Sweden. Participants were on a scale of 1-5 to select how they agree with the claims of the study form and also submit their own comments.

The aim of this master's thesis is to examine how shelving is organized among Swedish libraries that have switched from the Swedish classification system SAB to using the DDC, and what problems arise in this process. The method used is interviewing librarians at Swedish university and special libraries.The Swedish national library announced their swap to the DDC in 2008, and several libraries followed suit. The reported advantages with a switch were mainly that using an international classification system meant that Swedish libraries would no longer have to undertake a time consuming classification work, since most of the foreign literature already is Dewey classified. Disadvantages were that the DDC is not adapted to Swedish circumstances. Research on open shelving show that obtaining a browsable book collection requires a broad shelf classification.

The purpose of this study has been to investigate how frequently, and in witch ways, theories concerning the "late-modern" society are being used in the contemporary research of social work. My thesis is that theories concerning the late-modern society could be useful in social work research, foremost to shed light on, and broaden the understanding of, dilemmas and problems that are specific to the contemporary society. In the study I'm investigating all doctoral dissertations on social work written in Sweden between the years 2003 and 2006, and to execute the study I've applied a text analysis method in four steps. Simplified the four steps of the analysis can be said to investigate, if, how frequent, and in what way theories on the late modern society is being used in social work study. I'm also specifically investigating how problems exclusive to the late-modern society is being taken under consideration in the dissertations.In the analysis of my results I take a critical theory approach and I also discuss if theories on late-modernity is to be seen as a paradigm in the field of social work science.

Coastal sediments are important carbon sinks, storing organic matter and thereby helping to reduce the amount of greenhouse gases in the atmosphere. However, they can also act as carbon sources if the deposited organic matter decomposes rapidly, contributing to increased greenhouse gas emissions and global warming. Rapid decomposition partly depends on the degradability of the material itself. In this literature review, I examine which coastal plant species dominate different locations along the Swedish coast, based on coverage data from the ClimScape project (www.climscape.se). For the most dominant species, I investigated the type of organic matter they may contribute to the sediments and based on those results I qualitatively assessed which sites that may function as carbon sinks or sources.
