Given that the oil prices have risen and the environmental regulations has become more stringent, the interest in operating efficiency has increased. The project has investigated the possibility of producing electricity from waste heat generated in the diesel process. One technique to utilize and convert energy into electricity is the ORC (Organic Rankine Cycle). This process is based on the Rankine process (the steam process), the difference from the traditional Rankine process is that instead of water as a working medium, an organic substance is used. The main component used in the process is a evaporator, a turbine, a condenser and a pump.

The Swedish energy company Vattenfall is currently the owner of the district heatingsystems in Nyköping and Motala. To be able to also offer cooling solutions tocustomers are becoming more and more important. This report describes the resultsof an investigation of the cooling market in the two cities and the potential needs forcooling today and in the coming 20 years. The total potential for the coming 20 yearsis estimated to be roughly 17 MW for Nyköping and 9 MW for Motala.Two possible district cooling systems for each of the two city centers was modeledand a comparison was made between different cooling techniques namely absorptionand compressor chillers.Absorption chillers driven with district heating during the summer is one way ofincreasing the load in a combined heat and power plant and thereby the possibleelectricity generation. The cost of heat production must be low for absorption chillerto be able to compete as an alternative.

Intelligence is an elusive concept with strong links to business intelligence , in which organizations have recently more and more have incorporated the use of IT (Information Technology). A research carried out recently have identified the importance of effective monitoring, but there are few studies showing how organizations actually work in the field.A qualitative study consisting of the interviews with employees at an IT company was done to see how external monitoring is carried out in practice, in a specific company and how it would help the company to develop. The company we visited did not work with special procedures of any kind regarding external monitoring but still knew about the term and its meaning.The conclusion account for detected patterns as well as difficulties, including the definition of external monitoring which differs a lot between individuals. The patterns discovered points to the importance of clarity and objectives regarding the use of external monitoring for it to be effective and measurable.Keywords: External monitoring, Business Intelligence, Competitive Intelligence..

In this project a simulator has been developed (in C++) with the purpose of illustrating how changes in environmental regulations, tax levels and other policy measures affect the composition of an energy system. The aim of the project was to investigate how energy companies? investment strategies are affected when changes in economic and environmental conditions occur. A standard scenario has been created based on current Swedish conditions, but the user can create new scenarios and set parameters freely. The user is tasked with building power plants to supply the city/region with district heating and electricity during a pre-set number of years. When the simulation is finished the result is graded in the following categories: economy, environment and quality. To evaluate the simulator three scenarios were created (?early 20th century?, ?reduced environmental control? and ?future?) in addition to the standard scenario and these were compared with each other by examining how a select group of power plants perform under the given conditions.

'Teachers in current Swedish child- and youth literature' is an essay that attempts to understand the reasons behind why authors portray teachers the way they do. The foundation and focus point of this essay are ten Swedish child and youth books that were all published during 2012. Throughout this essay I have analyzed the fictional teachers in these books using the discourse analysis method but also employed a gender perspective. The main questions were these: Do the teachers presented in these books follow the curriculum LGR - 11, or do they represent the authors own education experience brought forward to current settings? Furthermore, was there a difference in how female and male teachers were represented? And if so what, possible reasons could account for that? The conclusions made were thus: ? The teacher characters within these books were mostly a throwback to days gone by, therefore reflecting the authors own memories of their school. ? They were mainly presented to the reader in a negative light which most likely has its roots in how Swedish school and Swedish teachers have been portrayed within the mass media. ? That there was indeed gender stereotyping in how female and male teachers were described..

Prior studies have shown that earnings management can be used either to inform or to mislead investors about the future performance of a company. However, few studies have examined the impact of earnings management on forecasting return on equity (ROE). The aim of this thesis is to investigate whether the ability to forecast next year's ROE is improved when taking earnings management, measured as discretionary accruals, into account. This is examined by comparing a forecast model that takes the magnitude of discretionary accruals into consideration with a model that does not. The study is based on companies that were listed on the Stockholm Stock Exchange during 2002-2012.

This thesis examines the verification of the terms and conditions stated in contracts based on the Public Procurement Act. In March 2013 the Swedish state procurement commission released " Good Business - A Strategy for Sustainable Public Procurement " (SOU 2013:12), which found that the proportion of control and verification is relatively low. The thesis examine how verification is carried out and looks for an explanation to why verification is not more oftenly performed. To answer these questions two care studies, based on seven semi-structured interviews, is presented as the empirical material. Network theory has been used to analyse the empirical results, and aspects of commonly used theories such as contract management and "Markets and Hierarchies" by Williamson has also been taken into account.

Background: Long-term stress can lead to reduced health among nurses which can result in impaired quality of care. Stress in nurses' work needs to be studied in order to prevent stress and impaired quality of care. Aim: The aim of this study was to describe nurses' experience of occupational stress and factors that contribute to occupational stress. Method: The method used was a literature review. Results: The analysis resulted in five themes which describe nurses' experiences of occupational stress and factors that contribute to occupational stress.

Hedge funds? importance within the financial system has during the most recent years increased dramatically. These special funds are unique instruments that differ from traditional mutual funds in a variety of ways, however especially in how they expect returns. Due to the fact that hedge funds are able to hold short positions they possess the possibility to become market neutral investment vehicles.Because of this possibility to sustain positions neutral to market fluctuations, the concept of absolute returns became a unique selling point for hedge fund managers and promises of stable returns unchallenged by market conditions was assured. This research paper aims to examine the theory of absolute returns in hedge funds by examining hedge funds from the Nordic region during the last years of economic turmoil that has occurred by  analyzing the results from their strategies, partially by quantitative measurements as well as qualitative.  The results show that none of hedge fund strategies managed to deliver absolute returns over the chosen period..

The purpose of this report was to investigate what characterizes a good psychosocialwork environment, and whether it may have impact on a vessel's safe voyage. Thisreport is proposed to increase the understanding of what creates a good psychosocialwork environment and its potential effect on safety at sea. In order to find out thesuccess factors for a good work environment group interviews were conducted in socalledunstructured focus groups. During these conversations, the participants discussedfreely by the question "what is a good psychosocial work environment for you?? Thesuccess factors were thereafter applied on selected accident reports, to investigate theextent to which they were represented and taken into account.The results of the study show three categories of factors: colleagues, communicationand competence, where colleagues are the main contribution to a good psychosocialwork environment.

The demand for biogas as vehicle fuel has risen sharply and there is a great need for increased production. A possible addition of vehicle gas can be produced by upgrading landfill gas which is formed by degradation of organic waste. This thesis investigates the potential of producing vehicle fuel from landfill gas in the region of Biogas Öst.In 2008, an amount of 32 million Nm3 landfill gas was extracted in the region. This level can be maintained for another ten years if the efficiency of gas extraction is improved. The annual production will decrease with time since landfills aren?t allowed to receive more organic waste.

This paper is an account of the work around the arrangement and registration of the archive of the Swedish Art-ists? Association?s archive. The Swedish Artists? Association is an association of artists that both makes exhibi-tions for their members? works and handles the Artists? House, called Konstnärshuset in Swedish. During the work with the archive the author faced a number of challenges and problems.

The main focus of this essay is to analyze whether strict employment protection legislation has a negative effect on the labour market possibilities for youth in the EU or not. To empirically examine the labour market possibilities for youth, data for unemployment rates and incidence of temporary jobs are used. By doing simple correlations between the different labour market characteristics and OECD?s employment protection legislation index the effect of the latter is tested. The result is that a tendency for youth unemployment and frequency of youth with temporary employment to be higher when employment protection legislation is strict can be seen.

The aim of this thesis is to study different aspects of the public libraries' investment in public access computers connected to the Internet. What level of accessibility can be found at the surveyed libraries concerning the number of computers open to the public, as well as chat and email services? What activities have been taking place with the computers in focus, and what have the goals of these activities been? Is there any control of content, and what aspects of the Internet are, if that is the case, subject to censorship. And how do the governmental policies relate to the surveyed libraries' intentions and activities regarding the Internet? In order to answer these questions, each main library in the 42 largest towns of Sweden was surveyed response rate: 100 %.

Background: Pedagogical documentation is currently used as a natural part of the educational activities under the revised curriculum for preschool.Aim: The purpose of this study is to see how preschool teachers perceive and define educational documentation in preschool. The aim is also to see what opportunities and obstacles that may arise over the pedagogical documentation.Method: The study was conducted along a qualitative approach with questionnaires in order to reach more preschool teachers and thus obtain a broader picture of the subject content. From a phenomenological approach I have taken account of the preschool teachers' experience and perception of educational documentation and designed it to my own interpretation.Results: The results show that pedagogical documentation is an important tool in preschool teachers work not only found to contain a product, but seems more like a collection of a lot of products to be brought together into a whole..
