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.

This essay deals with classification of images using the subject classification system Outline. This classification system is used in regional museums and they do often have large collections of pictures. The regional museums have their main focus of culture history. The purpose is to look at Outline from four different aspects: 1. In what way is the system constructed looking at classification theory, 2.

More efficient energy consumption is essential to secure a sustainable future, not least within the building and real estate sector which answers for approximately 40 % of the EU countries total energy consumption. One part of EU: s work to reduce the energy consumption is the directive on energy performance of buildings which among other things have lead to stricter demands on energy performance in new and renovated buildings.One of the difficulties with making buildings more energy effective is that it often demands big investments and although it results in lower operating costs the extent of these savings and therefore also the repayment time can be difficult to decide beforehand. To make it interesting for property owners and also tenants to invest in energy efficient buildings powerful incentives are needed. Favorable loans to energy efficiency projects are one example of governmental instruments that have been tested in other European countries with good results.Reduced operating costs appear to be the main incentive for property owners to make their buildings more energy efficient. The best result of an energy efficiency project is usually achieved by cooperation between property owners and tenants but in order to make that interesting it is important that both parts can profit from the savings.

This research shows and analyses how pupils in ninth grade in the nine-year compulsory school look at being multilingual, at the Swedish language and at Swedish as a second language. I also want to know if language and culture knowledge are taken care of in school as it says in official documents for the Swedish school and as it also is desired in an intercultural education. For my research I do eight interviews in a suburb school south of Stockholm.My work includes a limited account for the current research about being multilingual, Swedish as a second language and about the close relationship between language and culture. The applied theory is a social constructivist theory which in short can be explained like that we construct social structures that have consequences on the individual as well as on the society.I show in my research how the view of the world around the pupils influences their view on their languages, their school and their neighbourhood. I also draw conclusions from my interviews that language knowledge is little appreciated in school and that Swedish as a second language has a low status..

This bachelor thesis describes why investors should invest in environmentally certified buildings instead of non certified buildings. The report provides an overview of possible factors influencing an investor in the investment process of an environmentally certified building. The report explains why building companies find incentive to build green buildings and how a cash flow method can be adapted so it can be used in the valuation process of an environmentally certified building. Environmentally certified buildings are used as a strategy to reduce emissions that threaten the environment as well as a strategy to obtain market shares for the building companies. This report focuses on the economic advantages of an environmentally certified building.The construction- and real estate industry stands for approximately 40 percent of the energy consumption in the world.

Different institutional and culture contexts are argued to create differences in fathers practices and attitudes toward fatherhood. By in-depth interviews with swedish and spanish fathers, this Bachelor thesis aims to describe fathers experiences and attitudes toward fatherhood and how they relate to the institutional and culture context. The selection of swedish and spanish fathers aims to illustrate differences and similarities in two welfaremodels that differ. The main difference was how social policy provoces differences in the distribution between paid and non-paid work, where the spanish fathers remain as the main breadwinner. Differences also appeared in attitudes toward formal care.

In Uppsala, Sweden, Vattenfall has a combined heat and power plant. On the premises there is an engineering workshop with old fluorescent and mercury lamps that need to be replaced. This provides a great opportunity to save energy and money by installing more efficient lighting. The main purpose of this study was to present two functional and energy efficient lighting systems including control system. The lighting systems were designed by investigating the working environment, measuring illuminance and by simulations in the software DIALux.

Population growth leads to an increased need for new buildings, both residential and commercial. The regulations of structural design also changes with time. From a sustainable community perspective it may be profitable if existing buildings, that no longer performs their original function, are reconditioned. Knowledge and understanding of the surroundings of the residence must be available. Regulations regarding accessibility to all has increased.

Is it possible to convey spirituality through art and material culture? Is it possible to renew art within the traditional church so that it appeals and is understandable for the modern man? These are the fundamental questions of my master´s work, which has it´s starting point in a public commission for an artistic contribution to the new Pentecostal church in Kalmar. The work also addresses the question whether there is a need for symbolism, art and sacred objects also within the Pentecostal movement, a traditionally strong image hosting environment. If so, how is it possible to bring this in to the church without completely breaking with the tradition and ideology of the movement? I want to communicate the Christian message in a renewed way, and in this particular project also highlight the importance of using images also within the Pentecostal movement.

Work gets more seamless and the demand on workers increases because of changes in the labour market. Studies show benefits for workers and companies if the employee achieves a balance between work and family, a way to facilitate it is family-friendly policies. A study done by Unionen shows that three out of four white collar workers choose to vobba (working and caring for a sick child), which blurs the boundaries between work and family. Research on flexibility, organisational culture and gender structures shows how these aspects affect the balance between work and family. This is a study where seven white collar workers (three men) that vobbar and two managers (one man) were interviewed.

KALMAR UNIVERSITYDepartment of Health andBehavioural Sciences.Education of Social Work 21-40 p.C-essay, 10 p.Title: The Accepted Adjustment ? How Twelve Children Belonging to Ethnic Minority Groups Experiences Everyday Life in School.Authors: Kristin Lundin & Karin SwartlingSupervisor: Jesper AndreassonExaminer: Ulf DruggeABSTRACTThe aim of this C-essay, using a qualitative method and from a child prospective, explore how children belonging to ethnic minority groups participating in the Swedish education system at an intermediate level, experience everyday life at school and the interactions with their teachers. We have interviewed twelve children between the age of eleven and thirteen years old. The children have either immigrated (adopted children are included) or are born in Sweden but have at least one parent who has immigrated.The outcome from our study is that immigrant children have a positive experience of their daily life in school and in their interactions with their teachers. The majority of children state that they view their teachers as good educationalists.

This master?s thesis discusses the term physical theatre from a discourse point of view. It also focuses on aspects of power from a field theory perspective. The main theory used is Pierre Bourdieu?s field theory, and I try to apply this onto critical discourse analysis, mainly taken from Michel Foucault.

An archaeological excavation that was made in 2016 of a Pitted Ware Culture settlement at Tr?s?ttra in the northern archipelago of Stockholm was very rich in artefacts and features. Especially unique was the over 300 fragments of clay figurines that were found. Never had so many been discovered at a neolithic place in Sweden. In Scandinavia it is only on the Finnish islands of ?land that similar figurines have been found. The aim of this study is to increase the understanding of the clay figurines of Tr?s?ttra and ?land through comparative studies.

LRF Konsult AB is a Swedish company with over 135 offices. During the time 2006-01-01 to 2008-06-16, 397 persons were recruited. New people will continue to be employed and because of that a need for consistant information for the recruits has been noted. The essay question is what a handbook should include to guide a newly recruited person. The newly recruited person that is referred to works at LRF Konsult AB with farming companies. The answer to the question is that it depends on the needs the employee has.

The personal brand derives from the marketing brand, and argues that a person can take control over other people?s perceptions about him or her. The personal brand can benefit the person but it can also give advantages to his or her company. The interest in, and the purpose of the personal brand, has increased the last ten years. Leaders of large companies in Sweden consider it to be of utmost importance to have an influence on their co-workers.
