Future emission legislation puts great emphasis on increasing the efficiency of the engine, thereby reducing fuel consumption. The tribological contact between cylinder liner and piston ring is where an great amount of energy is lost due to friction, and by reducing these losses an reduction in fuel consumption can be achieved.The aim of this thesis was to evaluate the tested piston ring coatings against a plasma sprayed cylinder liner and rank these combinations of materials for friction and wear resistance. The coatings that were tested was Cr + Al2O3, (Al,Cr)N, two types of CrN and WC / C.The experimental tests were performed with a so-called pin-plate, where used oil with addition of an acidic mixture of sulfuric and nitric acid to mimic the acidic condensate formed when exhausts recirculate, were added with a continuous flow. The results were then analyzed by weighing, studies by optical microscopy and scanning electron microscopy (SEM) and profile measurements.The results from each material combination were that the plasma coated cylinder liner wears too aggressively in order to yield a ranking of the piston ring coatings based on the parameters of friction and wear resistance. It is therefore proposed that an alternative coating on the cylinder liner should be developed, lacking the large abrasive wear on piston rings and that can withstand the corrosive environment resulting in engines equipped with EGR.

Kamratposten is a swedish magazine aimed at youth aged 8-14. They write about almost everything that concerns youth, all the way from dealing with loneliness to animals and celebrities. This study concentrates at how they write about love. With a qualitiative narrative analysis of the 12 articles that concerns love from the 2013 issues of Kamratposten, I have tried to answer the questions: - What narratives about love are being constructed in Kamratposten 2013?- How do they construct males, females and gender in their articles about love?What I found was that the hetero normativity, or the heterosexual matrix as Judith Butler calls it, was very strong in the articles.

Many studies have shown that unethical acting can affect the share price of the company negatively. However, this is not always the case. The aim of this thesis is therefore to examine what it is that can cause the share price to be affected negatively by unethical acting exposed in media. This qualitative study is primarily based on interviews with institutional investors, but also with economic journalists and investor relations managers. Our conclusion is that there are three main reasons why the share price can be affected by unethical acting, namely economic consequences, the management's behaviour and psychological factors.

This paper aims to create a better understanding for how executing private matters during work hours affect the individual worker. In todays world the access to social medias, the Internet and all your friends is easy to access due to smartphones and computers. Prior research as described this both as a threat against the productivity of the worker and the moral of the workplace. While others mean that it is a source of recovery and something positive.This thesis uses a qualitative method and fifteen interviews where conducted with people between 20-30 years, who where working and living in Sweden. The theory of this paper is built on following areas: Time, the line between work and private, together alone, the brain and the affect it has on the dialogue between colleagues.

Cross-suckling, i.e. when an offspring nurses a female other than their own mother, occurs in pig production systems where sows are group housed during lactation. As production systems where several sows and their litters are housed together during lactation are getting more common, the need of knowledge regarding cross-suckling increases. The overall aims with this thesis was to investigate how sow behaviour and productivity are associated with the occurrence of cross-suckling, and to investigate consistency in sow nursing behaviour related to cross-suckling. The study included information about the first 4 parities of 40 LxY sows kept in outdoor and indoor production environments. Sows were single housed the first 2 weeks after farrowing and group housed (4 or 5 sows per group) from 2 weeks after farrowing until weaning, 7 weeks after farrowing.

This essay aims to explore the philosophical meaning of the expression ?present and real? in Clara ? or, On Nature?s Connection to the Spirit World by F. W. J. Schelling.

The Anglo-Saxon trust is not a new phenomenon, but existed as early as in the Middle Ages. The concept is customary among common-law countries, such as England the US,but unfamiliar to civil-law countries like Sweden. The person who creates the trust is called a settlor, the one who holds and administer the property is a trustee and the person who benefits from the settlement is called a beneficiary.In Sweden there is no legislation of how the trust ought to be assessed, but the need to understand it has probably increased with the internationalization.The Swedish Supreme Administrative Court has had a few opportunities to elucidate some of the uncertainties regarding trusts, but chose to abstain. With this The Swedish Tax Panel has very limited guidance from the court when they receive an application of an advance notice.A trust is not a legal entity nor a tax subject. This differs the trust from a foundation and they can not be placed on an equality from a Swedish tax perspective.In an advance notice, 2010-03-23 (dnr 103-09/D) om Inkomstskatt: Inkomst av tjänst ? värdepappersförmån, the Swedish Tax Panel equalizes the trust property with shares when determining how to tax the assets.

The aim of this literature study was to analyze how milk urea concentration is working as a measure of the nitrogen supply to rumen microbes and indicator of the environmental load. Questions included in this literature study were how to improve the dairy cattle nitrogen efficiency and what correlations there are between milk urea, nitrogen efficiency and crude protein content in the feed. Effects on the reproduction from high ration protein content are also addressed. Dairy cattle are today fed with large proportions of protein which could lead to high expenditure of feed and environmental pollutions. The nitrogen can be lost to the environment by different pathways; leaching, denitrification or by emission to the air.

Within the interconnected global markets of today; people, products, and information travel at a pace never met before. In light of the global retail markets recent integration, consumers are opened up to new products and are beginning to develop a vetted interest in the heritage of those products. Within literature this process has been coined "Country of Origin" COO, and its impacts on consumer attitudes, product value- assessment, and overall behaviors has been one of the most emphasized areas of "international business" studies, during the last three decades. Numerous studies have shown a correlation between positive or advantageous associations to a country of origin, and the actual products representing and coming out of that country. It is by this synergetic process that so-called positive COO-effects are brought forth.The goal of this thesis stems directly from the still unexplored potential for Swedish firms to differentiate their products and brands on new international markets, through a strategic and coherent communication of relevant Swedish COO-effects.

Thesis purpose: The purpose of this thesis is to determine how a technolo-gically enhanced shopping tool, synergizing eCRM tech-niques with personalized promotion at the point-of-sale, can increase customer loyalty by considering perceptions of current grocery retailer loyalty programs in Sweden. Methodology: An exploratory research was undertaken in the light of a qualitative method collecting primary data through focus group interviews. Theoretical perspective: The major considerations regarding theoretical aspects, for this thesis, can be addressed by Behavioral/Attitudinal loyalty and Relevance of Promotion. Empirical data: The empirical data, in regards to primary data, was ga-thered based on four focus group interviews. Conclusion: The conclusions of the thesis imply, that in order to make a loyalty program successful, it needs to firstly be conven-ient for the customer; easy to join, and provide an easy and time efficient display at the point-of-sale.

The ammonia emissions are an environmental issue since they contribute to eutrophication. By far the largest source of ammonia emissions is manure from agriculture and should therefore be reduced. Loss of ammonia is not only negative for the environment but also to the farmer who loses nitrogen that could have been used by the crop. The focus of this study has been emissions from spreading slurry where the loss can vary widely depending on slurry-, soil-, and weather conditions. There are mainly two different ways to reduce the emissions. One is to inject or mix the slurry into the ground to avoid air contact. The other way is to use acid to reduce the pH in the slurry to a level between 5 and 6 where the equilibrium is so strongly pushed to NH4+ that hardly any NH3 can be lost.

This thesis aims to study the impact of the transition from communism to democracy on the public libraries in Poland. The central areas of study are changes in: the organisation of the public library system, the role of the public library in society, the librarian's daily work and job situation and collection development. The thesis is based on qualitative interviews with public librarians, public library managers and researchers in Warsaw, Torun and Gdansk. The theoretical background consists of chapters outlining thoughts on democratic and communist library ideas and public libraries' responses to a changing society. The results show that the public library system has been affected by two major decentralisation reforms in Poland, leaving the libraries in the care of local governments.

This study had two different aims. The main aim was to investigate the dynamics and impact of African swine fever (ASF) on a farm in Uganda during a recent outbreak through a case study. The second aim was to estimate the presence of two important differential diagnoses of ASF: Classical swine fever (CSF) and Porcine Reproduction and Respiratory syndrome (PRRS).The field and laboratory based case study of the farm level dynamics of ASF virus during a recent outbreak (October-December 2010) on a farm in the district of Mityana, Uganda, was conducted, using interviews, ELISA and RT-PCR. The financial impact on the farm was also estimated. The impact of the outbreak was profound.

This Master thesis focuses on change conditions and change ambitions in Swedish public libraries. I have chosen to focus on three libraries that participated in a much-debated developmental project sponsored by the Swedish Arts Council almost twenty years ago. The aim of the project was to enhance service-quality, increase user-influence over media acquisition and library routines, and to redefine the concept of quality in the library context. I have made comparisons of the conditions and change ambitions between the project period 1991-1994 and present day 2009. To do this I have analyzed the evaluations of the above-mentioned project and the developmental plans that every municipality in Sweden is required to write according the library-law of 2004.
