Steam was used as a site preparation method to eliminate unwanted bilberry (Vaccinium myrtillus L.) in the boreal forest. The efficiency of steam to suppress bilberry was compared with prescribed burning and cutting the bilberry. Different combinations of steaming and/or cutting the bilberry were set up to investigate in which way steaming and cutting influenced the sprouting and regrowth of bilberry. The regrowth of the bilberry vegetation was monitored for 40 month. Steam was most efficient in suppressing bilberry.

This report will try to evaluate the use of rented concrete casting moulds, which are used to build walls and system of joists. The evaluation is only examining the economical aspects.The cost of using concrete casting moulds is a big part of the total production expenses. Therefore it is important that the calculated price not exceeds the final costs of the casting moulds. The calculated price is the price used in the process of making an offer.The evaluation consists of a comparison of the calculated price and the final costs for three building projects. It also evaluates the exploitation of the concrete casting moulds for each project.The report is made by Sven Gynne and Anders Alexandersson at School of Engineering, Jonkoping University, in cooperation with PEAB Jonkoping.

In Rio De Janeiro, 1992, was the first document signed that meant a responsibility for industrial countries to decrease their emissions, United Nations Framework Convention on Climate Change (UNFCCC). Thirteen years later was the first legal binding document signed, the Kyoto protocol, and for the first time industrial countries all over the world was bound to decrease their emissions on greenhouse gases. Within the framework of this commitment, three flexible mechanisms (Clean Development mechanism, Joint Implementation and Emission trading) were introduced with the function to reduce the economical costs of the commitment. The flexible mechanisms Emission Trading (ET) is what this report is about.The report starts with a description of carbon dioxide and it?s effect on the environment, thereafter comes a background review of the national agreements who lies as a ground to the implementation of emission trading as a management control measure in Sweden and the rest of the world.Keywords: United Framework Convention on Climate Change, Kyoto protocol, Flexible mechanisms, Emission trading, carbon dioxide .

The aim of this study was to examine how individuals with disability pension reason about a return to work. Action theory, as presented by Berglind, was used as theoretical approach. Qualitative interviews were conducted with five individuals who have disability pension due to mental illness. The respondents describe how they weigh benefits and disadvantages against each other. The main reason for a return to work is economical.

The thesis investigates if it is possible to replace several pumpimpellers with one controllable pumpimpeller, with a economical and a manufacturing analisys aspect. The studied pumpimpeller is mounted on a midrange wastewaterpump, N3127MT.In the thesis a contemplated manufacturing process is evaluated for a concept that are supposed to act as a controllable pumpimpeller. The pumpimpeller are studied in a manufacturing and flow matter and are presented in the thesis.The manufacturing cost is also estimated, and this has been compared to the storage cost and other costs that the existing pumpimpeller generates.The thesis also shows that the concept has minor losses in cutting quality aswell as the effiency comparing to the existing pumpimpeller.The concept also raises the manufacturing cost and this increasing cost makes the presented concept to expensive to carry through.An investigation of the costs that the existing pumpimpeller produces has also been done, and this shows that there is not that much expenses to earn regarding to for example the storage cost. The storage cost includes information from Flygt?s central storagecenter in Lindas, Sweden and Metz, France, and also an inventory about the pumpimpellers located at Flygt?s different distributors worldwide.The thesis shows that a controllable pumpimpeller will generally increase the cost for the pumpimpeller and the performance of the pumpimpeller will decrease..

This study examines the closure of public libraries, and the nonprofit organizations takeover of them as a phenomenon. The aim is to understand why the nonprofit takeover is common and what the takeover symbolizes and if the discourse in media invokes the views on libraries and the profession.Interviews were made with librarians, politicians and representatives of a nonprofit organization to study different sides of the phenomenon. Other empirical data were found in local and national newspapers and media-channels. I discovered that public libraries are highly valued by both politicians and the community. The study also showed that a library in a community makes people feel valued.

Background and problem: Corporate Governance is a well-known phenomenon which has been the focus of plenty of research where the board of directors and the CEO have been regarded as important actors. What's affecting decisions regarding these actors has been debated whereas media has been pointed out of having an impact. To decide whether or not media can affect Corporate Governance have shown to be problematic whereas it exists divergent views regarding this. At the same time this relationship is more explored in other contexts than the swedish one, although this one is considered suitable for this. Consequently there is a motive for examining medias impact on Corporate Governance in Sweden. Purpose: The purpose of the thesis is to explain if media has an impact on Corporate Governance at an overall level.

The purpose of this master thesis is to investigate what the work situation of children's librarians looks like in the year 2000, after the changes in society which took place since the 1980's. Did the tasks of children's librarians change during the nineties, and if so, in what way and why have they changed? Which new knowledge needs emerged for children's librarians during the nineties, and what was the cause of these new needs? Finally I want to know which needs for professional development arose, and how these needs are fulfilled. The thesis is based on qualitative interviews with children's librarians, library managers, library consultants, one representative of the Swedish school of Library and Information Studies and one member of SAB's children and youth committee. The study reveals that the identity of children's librarianship is strongly associated with the stimulation of language and reading.

The effects from a planned wind farm on the grid utility Gävle Energis electrical grid have been studied. The wind farm is planned to be built in the forest 15 km north of Gävle and will have 23 turbines with rated power from 2 to 2.5 MW, resulting in a total installed power between 46 MW and 57.5 MW. The grid connection will be made at 70 kV. The aim of the analysis was to determine what effects the wind farm would have on the power grid in the form of electrical disturbances (flicker etc.), need for new investment and raised operational cost. To allow the connection of the wind farm technical solutions (new lines, power stations and grid reinforcements) have been constructed.

Swedish consumption habits led to a discourse on consumption needs of the general public during the first half of the 20th century, involving primarily several institutions, but also a variety of popular movement organizations, among which we find Kooperativa Förbundet. In this discourse, ascetic consumption and a rationalized outlook on consumption were idealized, as the Swedes needed to be economical not to live beyond their means. The objective of this study is to investigate the ideals this type of discourse conveys throughout the latter half of the 20th century. This will be achieved by investigating selected editions of the cookbook ?Vår Kokbok? published by Kooperativa Förbundet.

At the turn of the year 2009/2010 there was a change in the regulations on sickness impact. This led to 328 persons in County of Kronoberg had an expired period of sickness benefit from the Social Insurance Office (Försäkringskassan) when they reached the maximum time for sickness or temporary disability compensation. These individuals were offered introductory programs with the employment services. The purpose of this study is to investigate how the population with expired period of sickness benefit from the Regional Social Insurance Office in the County of Kronoberg (Försäkringskassan Kronoberg) is described in the initial stage, and to explore how individuals who achieved expired period of sickness benefit from the Social Insurance Office (Försäkringskassan) talks about the meaning to get an expired period of sickness benefit regarding economic and social issues. The study was inspired by Grounded theory.

The purpose of this study is to examine teachers and school-leaders attitude to the school library. Both the cause of and the consequences of these attitudes are examined. In order to fulfil my purpose I have examined this through both literature and empirical studies. I have interviewed the headmaster, the school librarian and two teachers at two comprehensive schools. As theoretical framework I have used David Loertschers taxonomy containing theories about the levels in an ideal school library and Miles model of school development.

Background: As a part of a national health control program, Statens VeterinärmedicinskaAnstalt performs diagnostics to screen flocks for certain pathogens causing high mortality,morbidity and/or serious economical losses. There are several viruses in the programincluding IBDV (infectious bursal disease virus), IBV (infectious bronchitis virus) and NDV(Newcastle disease virus). Method: 96 serum samples were collected from different poultryflocks in Sweden and analyzed by ELISA, which are currently used in the health controlprogram as well as by a commercial prototype of a multiplex immunoassay manufactured byLuminex Corp., which is currently under evaluation at the United States Department ofAgriculture USDA. This 4-plex assay detects antibodies for the three above-mentionedviruses as well as antibodies of avian reovirus. In the context of this study the ELISAs run inroutine diagnostics as well as a REO ELISA were used as the standard for comparison.Result: The antibody concentration in serum from vaccinated chickens was high while theantibody concentration level in serum from not vaccinated chickens was low.

AbstractThe dependency of fossil fuels in the transport sector causes large emissions of carbondioxide. This problem can we reduce by using vehicle gas from digested solid manure and leftover of pasture. I have studied the potential for this in the county of Västernorrland. Thepurpose is to investigate how much vehicle gas that can be extracted.One central, large scale digestion and upgrade plant should be placed in Härnösand. Theamount of pasture and manure that is economical and practical available is enough to produce2,7-3,5 millions Nm3 vehicle gas.

The purpose of this paper is to investigate in which aspects the public library is affected by its local community. This is re-searched by means of an exemplified case study of a Swedish public library in which we analyze governing documents and the library website with respect to environmental scanning and mar-keting of library services.The research questions are: How are the local community?s demands on the public li-brary being described in the governing document? How is the public library?s response to the demands of the local community being described in the operational plan? How are the demands of the local community, as shown in the governing document and the operational plan, re-flected in the marketing of library services on the library website?Our conclusions are that:The demands of the local community are described in a general fashion in the governing document, but there is a lack of concrete political guidelines.The public library's response to the demands of the local commu-nity is described to some length in the operational plan, but not with respect to economical factors.The demands of the local community are reflected to some length in the marketing of library services on the library website. Many of the overall themes that we identify in the governing document and the operational plan can be found in the marketing directed towards important target groups..
