There have been changes in Earth?s climate system on both global and regional scale since the pre-industrial era and some of these changes are due to human activities such as the combustion of fossil fuels. This calls for the development of engines with a higher efficiency and less harmful emissions. One interesting concept is the Homogeneous Charge Compression Ignition (HCCI) engine, which has the advantages of potentially low emissions combined with high efficiency. However, HCCI with diesel fuel requires a relatively long fuel/air mixing time to ensure a "homogenous" charge.

The purpose of this literature review was to describe the paths of exposure and accumulation of organic pollutants into the tissues of farm animals. Organic pollutants can be spread in the environment by air and rainwater. Farm animals can be exposed to these pollutants for example by eating soil or contaminated plants. Many of the pollutants can then accumulate in the fat tissues of the body because of their lipophilic character. Brominated flame retardants and perfluorolated compounds are both pollutants of current interest.

Purpose: To evaluate the management development course held at FöreningsSparbanken in Ronneby during 2000. The evaluation aims to map and describe what effects the course has had on the participants. We will assess to what degree the effects meets the objectives of the course set by the manager of the bank (future management recruitment, leadership, change catalyst, aligning the strive towards a shared organisational objective). Above mentioned also implies that the organisation should be influenced in some regards. Conclusion: Our conclusion is that all of the participants have as a result of the course increased their emotional intelligence in varying levels. We also conclude that the course participants? progress has not spread to the non-participants.

This study investigates the effects that commercial computer games have on young individuals social comfort and learning progress. As a systematic study of literature, scholarly articles have been analysed in order to illuminate the positive as well as negative effects on social comfort and learning progress that may come with playing computer games. The social effects have mainly been discussed with role-playing games, such as World of Warcraft, as starting point, while the learning effects have been coupled with strategy games, such as Civilization IV. The study does not simply declare how these games can be good for these factors, but also in what respect computer games may prevent the development of young individuals socials skills and learning progress. The study showed that in spite of perpetual prejudices against computer games in the technological age, computer games might actually be good to use as a tool in order to authorize the development of young individuals regarding learning and social aspects.

Producing a building is a long and complex process. It consists of several parts, from the feasibility study and design stage onto the construction and finally the management of the building. The design process is a critical part of the process where construction plans are made. The quality of the plans affect the production phase in great extent and faulty plans can pose a risk for extra costs for all parts in the process. The cost of producing dwellings has increased the last years and the detail design process is one of many phases where improvements can mean cost savings within the whole building process.This report aims to point at parts within the detail design process which could be more efficient, regarding communication, follow-up and time planning, and to give suggestions for improvements.

The main purpose of this essay ?Mama & Papa usually do not have time? (Mamma och pappa har oftast inte tid), is to investigate what possibilities the pupils have when they need help with their homework. I also wanted to see what the actual conditions are when they do their homework. My second purpose is to see what their teachers think about homework and what they think are the positive and negative effects of homework. To be able to answer my main purpose I made a questionnaire with the pupils.

The advantages with product placement in blogs compared to traditional media is shown in earlier empirical findings where consumers found blog posts more credible and informative than a corresponding article in a web paper. It can therefore be argued that the informal structure and personal tonality of the blog reinforces the effects of product placement on brand attitude and intention to buy as the consumer has no persuasion knowledge and does not detect the rewriting of the product as commercial.This paper?s overall aim is to provide concrete implications for how to manage product placement on fashion blogs. The purpose of the essay is therefore to investigate the communicative effects of product placement in fashion blogs as well as to examine if a revelation of commercial interest behind a blog posts about a certain brand effects the consumers? attitude towards the blog and/or brand attitude and intention to buy.

The number of people who gets obesity increase wiht 1/2-1 % every year. Despite this number it is shown that obesity is a chronic and neglected decease. The purposes of this literature study were to describe how obesity effects adult and the risk of complications and the factors the nurse needs to know which effects patiens with obesity. The results shows the connection between obesity and complications and also what methods the nurse can use in the preventive work..

In this paper the authors aim to examine the effects on consumers using different strategies in a campaign within social marketing. A model by Evans et al (1996) has been used in order to see the different steps in which advertising catches the viewers? attention and eventually leads to action or purchasing. However, in the case of this thesis, the intention of the chosen campaign is to change the consumers? attitudes and behavior towards alcohol.

Automatic milking systems (AMS) are part of a growing trend in Sweden and the number of milk-producing farms is decreasing rapidly. One main reason for the AMS is its ability to facilitate work for the farmer. The effects of introduction prior to calving have not been documented earlier and farmers are not in agreement, however they seldom see a problem with the introduction. The aim of this report is to find differences between two groups of heifers, where one group is trained i.e. introduced to the AMS before calving and the other group is introduced after calving.

The aim of this master?s thesis is to obtain greater understanding of how children relate to the film medium and their experiences. This is obtained by listening to the children and observing their verbal and nonverbal communication in two focus group interviews. Children?s access to and selection of film are due to adult?s restrictions.

This thesis aims to study the indirect effects of the Europeanization on national parties and the presence of an established national opposition towards the European Union (EU) and its effects in Sweden, as a result of the so-called conflict of Vaxholm. The questions asked were whether or not it existed an established national opposition towards the EU, and if so, what the opposition consists of substantially. The research method, which was used, is a quantified text analysis on the chamber debates of the Swedish Riksdag and the party congresses of Socialdemokraterna. The study shows that there is an ambivalent opposition towards the EU and its effects in the aftermath of the conflict of Vaxholm.  Socialdemokraterna presented resistance, but did not manage to present apparent alternatives, which left the party with a rather indistinctive opposition. In contrast to the right-wing party, the left-wing party had some profound difficulties in positioning itself in the new and globalized economy. I therefore suggest, that it might be more providing and exhaustive to introduce Azmanova?s ideal-type analysis, which instead of positing parties on a left-right continuum, posit parties after respective party?s opinions concerning the risks or opportunities which the EU and the internal market?s effects. .

On a request from the water sewage plant Gryaab in Gothenburg a power quality survey was performed. The voltages and currents have continuously been sampled in the incoming 10 kV substation HSP01 from April-August 2008. Power quality measurements were also performed in Gryaabs other 10 kV substation HSP04 fed from HSP01 and at the terminals of the induction motor IN_PU4040 of 1.3 MW which controls one of the four large inflow pumps to the plant. The reason for the latter measurement was due to registered negative transients each time the motor was connected to the grid. The cause of the transients could be explained by the coupling in the substation, the ageing of the motor which could result in damage of the bearings or resonance in the motor circuit which amplifies high frequency harmonics.

New method for measuring road quality- A statisticalstudy of the relationship between road quality andsocioeconomic development A new tool with implications for road maintenance has the potential to yield statistical data for road quality in a large number of regions. This thesis investigates the possibility to develop a method, from this data, for evaluating the effects of road quality on socioeconomic development.The thesis is essentially divided into two parts. Part one looks to qualitatively establish the link between socioeconomic development and road quality and the second part focuses on how to develop a method for evaluating the effects of road quality on socioeconomic development. A method was devised using categorical data and a multinomial regression model. This method provides a comprehensive overview of the complex relationship between a variety of different variables.

Among young adults and especially women, psychological issues are common phenomena in the society such as depression, anxiety and stress. Research has shown that physical activity can be a complement for anti-depressant medication. The aim of this review is to examine previous research to find out how physical activity can provide positive effects on overall mood state in particular young women's psychological health. The results of this review is that there are support in the literature of young women that physical activity may enhance mood in studies of depression and anxiety symptoms and small support for the effects on reducing stress. Physical activity with both high intensity and low intensity has shown to have positive effects on depression and anxiety, but the physical activity has to be regular for long-term effects.
