Two elementary schools are now being built in Gråbo (in the municipality of Lerum),Röselidsskolan and Ljungviksskolan, which are both designed with solar thermalcollectors for the schools domestic water heating. During the summer while thelargest amount of solar heat can be generated, the activity hence the domestic wateruse in the schools are heavily reduced. Both schools are connected to the local districtheating system which makes it possible to use the solar collectors to deliver heat tothe district heating.The purpose of this thesis is to evaluate the two systems mentioned above and todetermine which system is more suitable to apply on a school. The building whichconditions were used for this evaluation is Röselidsskolan.A solar heating plant of each system type was dimensioned from the expected andknown conditions of the building. The purpose with the dimensioning was to makethe solar plants replace the ordinary energy source as much as possible.

The Swedish cooperative Lantmännen Ekonomiska Förening has initiated a project labelled "Operation Blåljus" that includes an extensive program for closing down elevators. The number of elevators will be reduced from 92 to approximately 15 after harvest of 2007. The objective of Blåljus is to increase the price of grain with 10 öre/kg. A project has been initiated at the Lantmännen Grain division where the purpose is to provide the farmers with support in their decisions and practical advice how they can load a 35 ton grain truck on 30 minutes. The result from the project will serve as a support system to the farmer in his ambition to achieve cost efficient systems to load a truck with grain on the farm.

A clean and affordable energy source for cooking is deficient in developing countries. People rely on fuels that contribute to environmental, social and health problems.Biogas is an alternative energy source and an increased investment in small-scale biogas production can in several developing countries be found. Several projects have started to use the technology in developing countries because of the benefits with biogas. Some cases in the establishment of biogas plants have succeeded and some have not. The study is a literature review supplemented by two field studies.

Göteborg Energi has a surplus of district heating during spring, summer and fall. The heat surplus is due to a constant production of waste heat from oil refineries and heat from waste incineration over the year. It would be desirable to increase the demand for heat and the uptime for the newly built combined heat and power generation plant, Rya Kraftvärmeverk. One alternative could be to integrate Rya Kraftvärmeverk with a pellet production facility. By producing heat, electricity and pellet in a joint process the energy use can be decreased.

This rapport contains an examination of the energy consumption of a kindergarten, which areas that have the largest impact on the energy consumption and what can be done to reduce those areas in ways that are relatively easy and profitable. It is also analyzed if it is possible to reduce the energy consumption from today?s consumption to a consumption that fulfils the demands placed on low energy houses by FEBY.The focus has been on reducing the energy consumption of the areas ventilation, heating system and hot water system, since those seemed to be the easiest ones to affect and since the building is quite recently built.There are different kinds of ventilation systems, at the moment the building have a CAV-system, which means that the ventilation is too high during large parts of the day. There are different ways to manage the ventilation system, for example presence detection, humidity sensors, CO2 sensors, temperature sensors and season adjustment. Many of those are in the end dependent on CO2 sensors to guarantee a good indoor climate, therefore the focus have been placed on this system.

Title: Pricing of IPO:s on the Swedish stock market Authors: Mikael Gustavsson Martin Kvist Henrik Wannberg Tutor: Anders Hederstierna Problem: There are certain sets of problems for underwriters when they are pricing potential stock-exchange companies. The problem partly consists of estimating the demand at an IPO and also to accurately value the business in comparison to the market. To set the price per share is problematic, since the company carrying out the public offering wants to optimise the amount of capital at the same time as they want the share to be subscribed in full. If the IPO would not be carried out, it could cause harm to the position of the underwriters. Purpose: To investigate whether underpricing exists associated with IPO:s on the Swedish market during the period 1995-1999. Method: The collection of data has been achieved by means of: Internet, E-mail and telephone calls. Conclusions: We have reached the conclusion that oversubscribing in comparison to the return at an IPO has an average growth of 3.3 per cent the first day, on every occasion of oversubscribing. For the studied population, including 138 initial public offerings, the average market value rise is 15 per cent the first day. When we made our calculations, adjustments have been made for the general index of Affärsvärlden (AFGX).

The aim for this paper is to investigate how a limited number of youth recreation leaders and leisure-time pedagogues view their vocational competence, which kind of power the persons in the essay experience to have in their workplace and which kind of status they experience that they have in comparison with other occupational groups in their schools. The final aim of the paper is to find out how teachers interact with youth recreation leaders and leisure-time pedagogues when it comes to their vocational competence. My questions are:How do a group of youth recreation leaders and leisure-time pedagogues view their professional assignments?How does a group of youth recreation leaders and leisure-time pedagogues view their power in their workplace in comparison with other occupational groups?How do a limited number of youth recreation leaders and leisure-time pedagogues view their status in relation to teachers, other occupational-groups and parents? Which role have my respondents been assigned by their team and why do they think they have gotten that role?To answer these questions I have used a qualitative method which includes four in depth interviews. The overall theoretical perspectives are symbolic interactionism and social constructivism.

In the essay, the view of mistakes and disciplinary sanctions within the military aviation and health and medical service, are compared. The comparison shows that military aviation and health and medical service could have several points in common on how mistakes may occur, but that the present view of mistakes is different betwen the sectors. The view of mistakes and disciplinary sanctions is explicit within military aviation, and is based on a clear ideology on how mistakes occur, which is characterised of a systematic approach. Within health and medical service, an explicit and unequivocal ideology on how mistakes occur is missing, but, however, there are implicit ideas about infallibility and perfection. The comparison indicates that the view of mistakes is also, possibly directed by a bureaucratic model (instead of an ideology on mistakes), which aims to legitimacy, but that this may happen on the expense of not taking surrounding circumstances into consideration.

In recent decades, demands has emerged that the companies shall take a greater social responsibility for the impact that they have on their environment and that this impact shall be reported, which is known as Sustainability Reporting. The Sustainability Report is based on a number of general principles that ensure the content and the quality of the Sustainability Report. One of these principles is the principle of completeness. In the research, this principle seems to have been interpreted in terms of number of reported aspects and indicators, which can be a limited view where only the existence of the aspects and indicators is observed. By including the degree of the reporting in terms of full, partial and no reporting as well as a comparison between the real and the alleged reporting, our intention is to extend the principle of completeness and to develop a tool that we also apply through an empirical survey in a particular area.

The combustion engines in today?s vehicles are getting more and more advanced and there are increasing demands on that the engines should operate during optimal conditions. Examples of internal combustion engine parameters which may be carefully controlled are the rate between fuel and air, that this gas mixture is homogenous enough and that it is ignited at the correct moment. Moreover, the requirements of these parameters vary depending on, among other, engine speed and load. To meet these requirements in all occurring operation conditions, it is required that many subsystems work together.

Which expectations did leading debaters place on fiction as an instrument in achieving societal changes hoped for by introducing the Public library? How can the value of fiction be described in relation to the mission of the Public library, according to these moulders of public opinion? Place and timeframe for this thesis is Sweden around the years 1905-1912 (period of formation of the Public library here according to the Anglo-American model). Starting point is the assumption that the Public library as a political institution is characterized by an ideological function. It produces meaning and norms, it sets standards of value. Method used is based on close reading and comparison.
