The work covered in this report includes a literature study of the diesel dual fuel technology(hereinafter referred to as DDF). The literature study covers earlier work that has been doneregarding the use of compressed natural gas (CNG) and diesel in a DDF system. Moreover a onecylinder research diesel engine was fitted with a CNG fuel system for experimental testing. Theinstallation of the engine and the test cell is described. Results from the tests are presentedcovering emissions, heat release and pressure traces from the DDF-concept.During the literature study it was found that most research was related to heavy duty dieselengines.

The purpose of this work is to explore and illuminate the circle times function and importance of preschool by the pedagogue perspective and the circle time design in relation to children's age group composition. The study questions are:What is the purpose of circle time in preschool educational activities according to the teacher and how does the teacher look at his own role?How do the teachers plan, design and perform the circle time of small children and big children's section? What similarities and differences exist?This is a qualitative study based on interviews with four preschool teachers and observations of their circle times. Research and theories showed that the circle time is a social training, provide a sense of community and is a ritual that gives a good daily rhythm.The results of the study demonstrate that the circle time is an important routine that occurs for a short time daily in early childhood education. The circle time organizes and structures the day for both children and staff group.

There's no doubt today that mankind has contributed to the changing climate byher use of fossil fuels. This must change in the nearby future. The Europeanleaders are expressing concern that renewable energy sources are not beingused to their full potential. The 2001/77/EC Directive on Electricity Productionfrom Renewable Energy Sources was accepted in 2001 to encourage thedevelopment of energy production from renewable sources, which isconsidered a step towards the fulfillment of the goal of the Union, that 12% ofthe gross energy consumption should come from renewable energy sources bythe year 2010.The objective of this thesis is to illuminate the common legislation of the EUregarding renewable energy with regard to goal fulfillment, judicial quality,conflicts with other goals of the EU and other faults. The objective is reachedby a hermeneutic study in which interpretation of written text is the mainmethod.

AbstractIn November 2011 the Swedish Government announced that they were conducting an investigation to examine what impact the conversion of existing rental stock to condominiums could have on the development of the Million programme areas. The proposal of converting rental stocks to condominiums aims to help people living in these neighbourhoods to private ownership, while still allowing people who want to continue to rent their homes to do that. This thesis intends to investigate the effects of the proposed reform from a management perspective. The maintenance of the areas built during the Million Programme gets more neglected every year that passes. The majority of the housing stock is rental properties and extensive renovation of the surface layer, tribes and public spaces are essential in all Million programme areas studied. By transforming a portion of the housing stock into condominiums and by improve the living environment through renovations, these areas would be able to gets more attractive.

The large-scale soy cultivation has negative consequences for the habitat of local populations because of the intensive use of pesticides and the destruction of rain forests and eco-systems. GM soya, varieties are often used. The majority of Swedish people, however, do not want GM products in their food. It will be hard in future to ensure GM free food, particularly foods that come from countries where GM crops are grown on a large scale. It is very difficult to avoid cross- contamination when both GM and non-GM crops are grown in the same area.

The purpose of this essay is to discuss the base of sociology from an existentialistic perspective. The discussion takes it's position in the debate on the crisis of sociology, and aligns with Alvin Gouldner's understanding of the crisis. Gouldner believed that the crisis of sociology was mirrored in a sociological method that failed to describe the social reality that it meant to describe; a lack in self-criticism and self-reflexivity, a lack in self-containment in relation to state interests and a lack in moral engagement. This raises a number of questions, which I discuss in the essay. What is the role of sociology in our society? How shall we form a method that responds to the social reality that we sociologists aim to describe? How can we make sociology more moral?Existentialism offers a starting point to describe these questions.

This is a bachelor thesis about arable land in Varberg, from sustainability and it?s relation to local government and management. Arable land has become more important as a natural resource from a global point of view and in concerns of higher demands of food supply, as a result of population growth, higher consumption worldwide and climate change. But the arable land in Sweden is being exploited an increasingly rapid pace and the arable land in Varberg is not an exception of this development. The issue is most topical and the discussion holds questions about a declining agricultural sector, the formal and administrative protection of arable land and because other interests of land use often is given higher priority in community development and planning.

The current financial crisis has left its mark. It has even hit the major Swedish banks who have shown large losses. The media has not been slow to take note of this, and the constant political debate about the bonus culture has been reinvigorated. Our aim is to find out how the major Swedish banks relate to the publicity and describe how and why senior executives are rewarded, and what strategies banks are using in the design of their reward system to maintain a legitimate behavior, and thus the confidence of its stakeholders.As a starting point to answer our purpose we have used the agency theory that describes our view of how various problems occurs and how incentives can be established in order to get senior executives to act for their owners' interests. Modern theories of reward systems are taken from a variety of authors, these theories give us an insight into how reward systems can be designed in banks.

Masters thesis in Business Economics IV, VT 2012Linneuniversity in Kalmar Authors: Johanna Susaeg and David JohanssonTutor: Petter BoyeExaminer: Karin JonnergårdTitle: Fair value - How real is it? Background and research discussion: The concept of fair value is today connected with great uncertainty, which may be a result of the various guidelines developed during recent years. Hence, auditors have an important role in situations where they have to make projections concerning fair value and also do inspections of the management´s own assumptions.     The critique that has been shown regarding fair value is that it can be difficult to estimate, especially when there is no active market to proceed from. This problem has been confirmed through that the management often uses the estimations subjectivity to deliberately show higher or lower values in the accounts. Purpose: The purpose of this essay is to study and describe auditors, appraisers and real estate companys interest and procedure in valuation of real estates.  We also going to describe theirs view on fair value of real estates plus analyze and explain the actor?s roles in the valueprocess and how their particular interests can affect the final valuation in different situations. Methodology: The study is characterized by a qualitative method containing a pilot interview and several personal interviews with auditors, estimators, and real estate companies.

I det moderna samhället är det många faktorer som leder till upplevelsen av stress. Dessa faktorer kan bland annat bero på samhällets snabba förändringar, de höga kraven, och att vi ska finnas till hands större delen av dygnet. Kombinerar man dessa faktorer med individens olika sociala roller är risken hög att individen upplever kraven som stressande. Förutom arbetets krav existerar även krav efter arbetet när man måste ägna sig åt familjen. Min studie fokuserar på att ta reda på vilka faktorer som kan ge upphov till stress hos arbetande föräldrar.

Organizational democracy has been a popular research area in recent decades but the implementation in real organizations is slow (Kokkinidis, 2012; Verdorfer, Weber, Unter Rainer & Seyr, 2013). Several researchers (Schön Jansson, 2012; Falkheimer, Heide & Johansson, 2013) argue that communication practitioners have a key role in democratic processes and that because their job role is under constant change there are only a few modern studies regarding the subject. The purpose of this study is to illustrate how communication practitioners in private and public organizations experience their role in the process of internal communication and to what extent they are aware of, and work with internal organizational democracy.The practitioners we interviewed had a strong feeling that they were a support function for the business and the organizational management. As a result of the study it is clear that communication practitioners are very loyal to their employers and to the organization they work for. They are, therefore, not neutral in their professional role and argue that their task is to represent the management's interests.

In a city sometimes conflicts arise between either to save the species-rich vacant lots where many species thrive, or to build new buildings. Green roofs can then serve as a refuge for plants and animals that have had their natural habitat destroyed or diminished. Today we know too little about green roofs contribution to the biodiversity in the cities. We also know very little about how various types of vegetation on roof can increase biodiversity and its ability to attract different species.The aim with this study was to examine how different types of vegetation on the roofs affect the biodiversity of the invertebrate and how species-composition and number of individuals differ between the roof- and groundlevel.This study has been carried out on Augustenborg Botanical Roof Gardens in Malmo, and in an area about 1.5 kilometers away from Augustenborg. Three different types of vegetation on the roof and ground floor were selected: sedum- ruderal and grass.

This Master thesis is performed at the request of the forest company Mellanskog and the local municipality of Borlänge in Sweden and aims to establish recreational adjusted forest management plan for the areas of Mellsta and Skräddarbacken in Borlänge. In all types of urban forestry it is very important that the management plan are accepted by the general public. To make sure that also these plans of future measures, pass in the public, interview studies have been performed in which the public wishes and interests have been examined and applied in the management plan. To make sure that future measures in the forest may be accepted by the public when the forest harvester enters the woods, it is very important that a well functional work of information has been made. The people living close by the forest shall have been informed a couple of weeks before the time of measures and it must also be good information available that explains what is to be done and why.

The purpose of this thesis was to find out what experiences teachers have from using a class blog in teaching. What are the advantages and disadvantages by the use of blogs in education?I have used qualitative interviews with four teachers in grades 1 to 6 who have worked with a class blog in teaching between one and three years.The study has shown that teachers' experience is that the blog serves as motivation and promotes learning for many different pupils and that, together with other digital tools is more equal. The main benefits that teacher mention is the expanded concept of text that offers multiple forms of expression and the authentic reader, which makes it more real, important and meaningful. Other benefits that come up are that it helps students to see their learning and learn from and with each other.
