This master thesis was a subtask of a project called EMIR-1. The goal with the thesis was tobuild a system for particulate mass measurements in one of the engine test cells at KTH. Theparticulate mass measurements are planned to be measured with a TEOM.The exhaust gases must first be diluted with air before the sample is sent to the TEOM.Therefore an ejector diluter for this matter also was designed and evaluated in the thesis.Emissions measurements have been done both with and without dilution to determine thedilution ratio. Tests have been done for different speeds and loads.Problems with stability of the dilution ratio have been an issue throughout the process andpressure pulsations in the exhaust pipe are believed to be the cause. More tests have to be done tomake sure that this is the problem.One idea is to make the inner diameter of the diluter nozzle smaller and see if it changes thedilution ratio stability.

Technological advancements in information and communication technologies (ICT) have resulted ina need to use ICT in schools. Sweden has actively promoted ICT in schools since the early 1980's.In Japan, 1994 saw the government's first step towards active promotion of ICT in education. In thisstudy, we have compared the strategies used to promote the use of ICT in elementary and secondaryschools in Sweden and Japan. Our findings suggest that a similar 3-step approach was used in bothcountries: 1, infrastructure; 2, effective use of ICT; 3, implementation of ICT. A significantdifference was found in the way the two countries planned their strategies.

Swedish healthcare has experienced increased economic pressure during the last decades and organizations have faced many changes. Managers and their roles in organizations have also been affected by the changes. Traditionally, managers in the healthcare sector are highly specialized doctors with a strong medical background. In the thesis, we study a big private healthcare company with an ambition to lead the development in the sector. In order to accomplish its goal, the company is trying to change the organization of managers.

The essay treats how a process of implementation was executed and the teachers? relation to two curricula, Lpo94 and Lgr11, with two different grading systems, which have functioned as models for one and the same year. The purpose is to investigate the ways in which a change in curricula and syllabus affects teachers in their teaching and assessment practice in the subject of Swedish at secondary school. The investigation had a phenomenological approach and was executed by means of in-depth interviews, questionnaires and one observation. The results are based on a methodological triangulation with qualitative and quantitative data where visible similarities and differences are brought out.

The Rwandan genocide 1994 was a well-planned and ethnic based act that killedapproximately 900 000 people. The UN and the colonial powers are getting much attentionand are worldly discussed about the failure of interference before and during the genocide. Inthis study the history of colonial Rwanda will be analyzed and the UN relation will bediscussed. This will be done by examining how the colonial powers have affected Rwandathrough history and how the UN have responded upon the challenges towards Human Rights.Questions about accountability and failure will also be discussed and analyzed. This has beendone by analyzing highly reliable documents and books by NGOs and scholars.

This report deals with life-history variation for Eurasian perch (Perca fluviatilis L.), with special emphasis on age and size at maturity in females, in perch populations that have changed in size distribution. The collection of fish samples was made with multimesh gill nets year 2011. The perch?s length, height, weight, status of gonads has been analyzed, and by observing the opercular bone the age has been determined. In two lakes close to Umeå in northern Sweden, Fisksjön and Ängersjön, the live-history traits of perch have been studied.

The essay discusses how to look at a equality plan of a academic department experiences the, gender equality in general and how power is portrayed from a gender perspective in the academic department. Through the use of qualitative interviews and a short survey the results have shown that few of the staff members have knowledge about the equality plan and few are familiar with its contents. Furthermore results show that the academic department is run hierarchyilly and that both vertical and horizontal gender segregation exists.The climate at the academic department is characterized by the will to work with gender equality but so far there have only been few exercised or planned efforts to do so. The gap between theory and practise is wide, the will to be seen as an equal academic department concerning equality of men and women seems important. The conscious or unconscious strategy of covering up the real gender equality seems to be done by focusing on the numerical equality..

AbstractThe purpose of my essay was through economically, socially and psychologically aspects examine the impact Bethesda Children´s Ministry made on families.

The purpose with this studie was to examine how individuals with experience of a long-term drugabuse describe their transformationprocess, and if this process has contributed to a change in their selfdescription. The studie was delimit to examine the transformationprocess, not in relation to what sort of abuse the informants had, or in relation to gender. The studie anwered questions concerning motivation to stop abusing, how the informants started the drugcareer, and how life as an abuser is described. In the studie qualitative method was used, five semi-structured interviewes were made with individuals who had a long-term addiction in the past. Symbolic Interactionism was the theoretical frame of referense that was used for analyse.

The purpose of this study is to see what obstacles and opportunities the staff on a residence for unaccompanied children experience when trying to integrate these children into the Swedish society. I was also interested in how the integration of these children worked. I have interviewed the staff with a qualitative method. The result was analyzed with the help of Diaz integration theory and Bauman´s theory "us and them", and also with the previous research in the subject. My conclusion is that integration is a complicated concept that is experienced and interpreted individually. There are both obstacles and opportunities in the work with the integration of unaccompanied children. The result shows me that the schools? role and the legal guardians function should have been better planned and framed from the start.

In today?s society, many people are physically inactive and the health care is for example usingPhysical activity on prescription (PaP) to work against it. In order to increase the physical activitylevel in people they need to feel motivated and there are many factors that can motivate people. The purpose of this survey is therefore to explore the leaders of PaP and their thoughts about whatmotivates clients with PaP to increase their physical activity levels. This is explored by aqualitative method incorporated with semi-structured interviews with four respondents who workswith PaP.

This study has been performed with the help of forest machine operators in order to improve the forestry planning at Holmen Skog Örnsköldsvik-region. For Holmen Skog forestry planning is basic for a successful forestry. In a survey I have investigated what can be improved in some areas that are planned for harvesting. The result of the investigation will be used to support the machine operators as much as possible. The study has generated 49.5 % of responses and because of this low response rate, no clear conclusions to anyone else except the responding machine operators can be drawn. It has been proved that there are some details in the forestry planning system that are inadequate, such as marked routs for trails, tractor paths and buffer zones against streams. The quality of forestry planning varies greatly between different locations, as much as 50 % of the responding machine operators thought so. Over 40 % of the responding machine operators claim that the information from Holmen is insufficient. One thing that would improve the forestry planning within Holmen would be to educate all forestry planners and then do continuous follow-ups..

Climate change is expected to lead to increased rainfall and higher temperatures, among other things. This will have a major impact on our cities. Floods can lead to property damage as well as damages to human and animal health. Higher temperatures will increase the frequency of heat-related health risks and premature deaths. The consequences of climate change will be particularly large in our cities because of the city's morphology with a high amount of paved surfaces and buildings that affect the natural processes in areas such as drainage and absorption of solar radiation.

Recent studies show that manufacturing companies to a larger extent use historical cost accounting in their internal accounts, at the expense of calculated costs. The explanation behind this is claimed to be that firms are subject to careful scrutiny by the stock market. Consequently, top management stresses the need of evaluating all parts of the firm from external accounting. However, lower management levels express a general concern that the incentive to invest in machines will decrease. This master thesis aims to investigate whether or not there is an objective reason behind this concern.
