Hydropower is an important source of energy in Sweden and accounts for about 46 % of the total energy production. Sweden has about 1 200 hydropower plants and with the intention of raising the pressure head of the water and to store water, dams are built by the power plants. The storage reservoirs make it possible to adjust the energy production by demand and season. Dams in connection to the reservoirs are subjected to additional loading during periods of high floods or when an icecap in the winter is formed on the reservoirs. In order to maintain the dam safety, the power companies in Sweden are working with guidelines for dam safety from RIDAS.

This master thesis has three purposes. The first purpose is to give a theoretical background of how to divide up forest estates and to study how the legal system for these matters works. A literature study has been carried out to give the background and a theoretical model has been made for analysing the law cases. The first purpose also partly touched the decision process in dividing up forest estates from point of view of the law of land parcelling (FBL), point of view. The second purpose is to examine effects of a change of production requirements in 3 cap.7 § FBL as regards dividing up forest estates of private forest owners.

AbstractThe assignment were assigned by Camatec Industriteknik AB. Camatec is a Karlstadlocated consulting company, they make everything from pilot studies to complete projects in mechanical design and calculation. They even have their own patented product, Camcoil. It is a winder for steel strips and is used for example with hardening of the steel strip. The assignment has been to solve the problems encountered by some customers within this product.

Under framtagandet av nya produkter måste ett antal prototyper tillverkas för att verifiera konstruktionen. För en metodingenjör som tar fram reparationsmetoder innebär prototyptillverkning att tankar som växt fram under utvecklingsfasen kan provas för första gången på en fysisk produkt. Detta sker relativt sent i produktutvecklingen och eventuella ändringar som kan uppstå på grund av att servicevänlighet inte uppnås blir mycket kostsamma. Om däremot prototypen där metoderna verifieras för första gången är digital och detta sker tidigt blir kostnaderna för eventuella ändringar avsevärt mycket mindre. Modellen som ligger till grund för metodstudierna kan sedan används för att skapa ett utkast till service litteratur, detta medför att även den delen av slutprodukten kommer att vara i fas med övriga utvecklings avdelningar. Under detta projekt har en digital prototyp av en Scania motor använts för genomförandet av metodstudier.

Infectious Bronchitis (IB) is a highly contagious viral respiratory and productiondepressant disease distributed world wide. The disease is caused by the InfectiousBronchitis Virus (IBV), a positive RNA strand Avian Coronavirus within thegenus Gammacoronavirus. Due to a combination of high mutation rate and atendency of recombination a constant emergence of new genotypes and serotypesis seen. In Brazil, a country with an extensive poultry production and majorproblems with disease control, the diversity of circulating strains are wide andoutbreaks of clinical disease despite intensive use of vaccines are common. Theaim of this study was to investigate the presence of IBV and to identify genotypesof isolated IBVs in a limited number of layer flocks in Bastos, São Paulo, as partof the screening for circulating genotypes in the country.

The purpose with this study was to analyse students' conception of living things, and to establish how a social constructivist learning situation affect their conceptions. The method consisted of questionnaires, followed by group discussions and a final survey. The main result was that students have everyday conceptions about scientific phenomena that are reinforced by the social interaction. Some students were positively influenced by the interaction with their peers, where non-scientific conceptions were replaced by conceptions of a scientific nature. Furthermore, the cultural artifacts are of very good means, but the study showed a strong need for a knowledgeable person, e.g.a teacher, to guide students in the right direction during the discussions.

To assure good quality the software needs to be tested to find errors and to verify that the programme meets the customer?s expectations. Traditional methods are usually used in software development and means that a number of predetermined steps are followed. By using agile methods the development can more easily be adapted to the changes on the market. With these methods the testing is carried out continuously throughout the project.

Tomato production is a common and important agricultural activity in Nicaragua. During the last decades tomato producers have suffered great yield losses due to begomoviruses (family Geminiviridae). The genome of begomoviruses generally consists of two circular ssDNA components, DNA-A and DNA-B. Tomato yellow leaf curl virus (TYLCV) is an example of a begomovirus with only one component. An approach to manage the virus epidemics has been to breed a cultivar with begomovirus resistance genes, which have been transferred from wild tomato.

The main aim of this paper is to illurninate how a group of immigrants meet the publiclibrary in Sweden. I have chosen to discuss Iranian immigrants' meeting with the publiclibrary in Borås. The investigation (qualitative interviews and inquiries) has taken placein the public library of Borås and partly in a local library with high density of immigrants.A theoretical perspective deals with the case study of dual marginality, where theconception of the "Marginal Man" or "The Outsider" is central. I have indicated how theprevious authors have considered this problem, to live on the verge between twodifferent cultures and how individuals react on it.The interviews and inquiries answered by Iranian immigrants are the most importantmaterial in this investigation and the result of them is connected to the theoreticalperspective and a discussion, what it means for the public library..

Purpose/Aim: The comprehensive purpose is to study how the political journalism is framed, and how the party leaders, with focus on the authority, are constructed in the press.Material/Method: Firstly 84 articles articles printed in the swedish newspapers Aftonbladet, Dagens Nyheter and Svenska Dagbladet have been analysed. Secondly, a textual analysis by means of a critical discourse analysis.Main results: Media are inclined to frame politics as a game or a strategic race. The partyleaders are ascribed authority in different ways. This ascribed authority can also be deconstructed.Key words: Media and politics, party leader, discourse, democracy, framing theory.

The purpose with this essay was to examine and bring a deeper comprehension about brands as a phenomenon. We also wanted to study if strong brands could develop in to strategic competition means and by that expand their market range. To do this we used a qualitative method. We started by gathering a theoretical basis. This gave us a platform, which helped us learn more about the subject, brands.

The aim of this Master?s thesis is to study various views of sponsorship in relation to public libraries as found within three cultural policy documents. The main objective is to discover which ideas are considered relevant in the partnership between the Swedish retail chain, Åhléns, and the children?s public library, ?Room for Children? (Rum för Barn). In 2005, Åhléns provided SEK3.14 million in sponsorship to ?Room for Children? at Kulturhuset in Stockholm.

To increase the quality in their products ABB is working towards a cleared order concept. That means that all customer specified options are to be known before they start with order calculations and construction. As it is today they use paper checklists to achieve this. One order may have several reactors, and for a reactor there can be several different alternatives. For each alternative a new checklist must be filled out.As of today all reading of the customer specification and checklist fill in with is done by hand by different persons, and sometimes the same data is read more than one time.

This work examines the students´ thoughts on climate change with a focus on carbondioxid through photosynthesis and the carbon emissions from cars. The study is based on two subject areas, one with a focus on enhanced greenhouse effect, and the other focusing on photosythesis. The survey was conducted by means of qualitative interviews with students in grades four and six. The results describe that student´s understanding for photosynthesis and the carbondioxids function for photosynthesis doesn´t change significantly from grade four to grade six. I have divided the students inte three levels based on their understandingof the various fields, and their use of adequate concepts.
