Forsmark 3 ?Ett Framtida Biobränslekraftverk?

Recent turmoil surrounding nuclear power as an energy source, especially since the accidentat Fukushima, has largely contributed to the debate of whether or not nuclear power should beused as an energy source. This study has examined the economic feasibility of replacingForsmark?s 3rd nuclear reactor with a bio fueled power plant, and find out how this could bedone.The power generation that has to be replaced is equal to 1170 MWe. To replace this, 6 largescaleCFB-boilers, each providing over 200 MWe, were necessary. In addition to this, eachboiler required their respective turbine sets, comprising one high-pressure-, and one lowpressureturbine with intermediate reheating capacities.Based on this, a rankine-cycle was modeled using the software EES, to be able to calculatethe total heat required in the power plant.

Barn med språkstörning interagerar med olika samtalspartners : En samtalsanalytisk studie

Language impairment affects the ability to communicate. Children with languageimpairment have difficulties in using language in interaction to various degrees, and the contributions of the conversational partner are of great importance. The use of languagein interaction can be analysed by means of conversation analysis. The purpose of thepresent study was to study interaction of a group of pre-school children with language impairment with four different conversational partners. These were a peer with languag eimpairment, a peer with typical language development, a pre-school teacher and a parent.

Energibalans Dåva Kraftvärmeverk

To be able to measure high-surge voltages and transients with short rise times youneed measuring instruments with a high sampling frequency and large Bandwidth.These surges and transients occur primarily at lightning but can also occur at forexample at connecting errors at an electrical switch-gear. This report describes thework with finding two solutions for measuring and log data from these surges andtransients. One temporary solution where a measurement program has beendeveloped. A second solution where different company solutions have been analyzedto decide which fits best. For these measurement solutions two solutions for bringingdown the voltage has been used.

Re-design of Toledo Riverfront : from industrial past to sustainable biodiverse future

Effects of climate change, urbanization and global homogenization are resulted in the degradation of land and losses of natural habitats. Ecological design integrates nature into urban environment by respecting natural ecological principles and processes and creating resilient urban biotopes which also can be used by local urban communities. The aim of the thesis is to answer the research questions: How ecological design principles can be applied for re-design of Toledo Riverfront (with requirements of the design competition)? and What is the ecological design in landscape architecture? I participated in the USA design competition with the aim to create a vision and redesign of Toledo Riverfront in Ohio State, USA. The site is located in the south point of Lake Erie. As a result of a long industrial activity, riverfront of Toledo had been transformed into inaccessible and abandoned brownfields. In my proposal I applied ecological design principles on three scales: the city of Toledo by reinforcing of ecological connection and creating green corridors along the river; the intermediate scale by suggesting public parks along the river front and on the fine level by proposing detailed design including remediation of the site and use of dredged material.

Klassrumskommunikation och lärande : En studie med fokus på kommunikationsmönster, frågornas roll och uppföljning av elevuttalanden i klassrumskommunikationen

The purpose of this bachelor's thesis is to examine how public libraries in Sweden handles their weeding procedures. A series of questions are asked: How does libraries in Sweden motivate weeding? What principles constitutes the procedure of weeding? Which aspects are given most importance when weeding is decided. How does views on weeding differ between libraries of different sizes? How does longer or shorter professional experience influence the view on weeding? The study was done through an online questionnaire which was sent to a number of staff members on different libraries via e-mail.

Från input till output: En kvalitativ studie om hur resultatkrav inom biståndet påverkar svenska civilsamhällesorganisationer och mottagarens möjlighet till participation

This bachelor thesis is based on the current discourse within the aid policy, whichhighlights and focuses on measurability and reporting of results within the development cooperation.The purpose of this study is to investigate how the Swedish CSOs Diakonia and Plan Sverige, bothoperating many of its activities through which Sida are directing Swedish aid, are influenced by theresults agenda in it?s work, and to investigate which impact this has on participation of the recipient.The research is based on information collected through examination of relevant text such asdocuments from the organisations, agencies and from debate articles and inquires. Together with datacollected through informant interviews with informants from the organizations this information hasbeen analyzed through a qualitative content analysis. The study show that the demands occurringwithin the development cooperation mainly generates quantitative, short term results in order tomaintain legitimacy as an organization. The focus has changed from a traditionally high reliance onthe organizations activities to instead focus on which results the organizations can present as a resultof its work.

Mekanisk integration av en IR-detektor i en Stirlingkylare

The master thesis ?Mechanical Integration of an IR-detector in a Micro Cooler? has beenperformed at FLIR Systems AB in Danderyd. FLIR Systems is a world leader in the design,manufacture and marketing of thermal imaging camera systems.The thesis project is divided into to two areas, Production Method and Noise.The Production Method concerns the positioning of a detector on the cold finger within the IRcamera.The detector has to be positiond with very high accuracy at the center of the cold finger,so it can be placed in line with the optical axis to avoid movement of the picture during zooming.The positioning of the detector is at present done with the help of specially designed guides on aplate on top of the cold finger. The design workes well but the special machining needed for thisplate is very expensive.The goal concerning the production method was to derive a new more cost effective method forthe assembling and positioning of the detector on the cold finger by replacing the guides on theplate with a reusable equipment or some other alignement operation.Several concept ideas have been generated with the help of concept generation methods in theform of concept classification trees and concept combinational tables. Two of these conceptswere selected to be further refined.

Avskaffande av exekvaturförfarandet : En studie av kommissionens förslag till en reviderad Bryssel I-förordning

In order for a judgement to be enforceable in another Member State, there is a certain requirement for an "intermediate? court procedure, a so-called exequatur procedure. An exequatur procedure is both expensive and time-consuming. The average cost of the procedure within the EU is 2 200 euro in a case without particular difficulties. In more complex cases, the cost of the procedure can be validated up to 12 700 euro.

Library Lovers Att hitta nya vägar - rosa marknadsföring av bibliotekspolitik

AbstractSwedish tuition for immigrants (SFI) is a public adult education program in Sweden that was created in order to provide the immigrants with basic skills in Swedish. People with different backgrounds speaking different languages learn together how they should communicate in Swedish, both orally and in writing. For those who teach SFI it is important to know which factors have positive effects on the Swedish language acquisition. One of the questions to be asked is if the learning materials´ genre has any effect on the SFI students´ proficiency, in particular, oral proficiency. Scientists as von Franz, Vygotskiy and Bettelheim argued that fairy tales, as a genre consciously or subconsciously recognizable by all the people, present texts that are easy to acqiure.

Avstånd och användning : en jämförande studie av lärares använding av skolbibliotek i undervisningen

The purpose of this Master thesis is to examine whether there is a connection between distance to the schoollibrary and the extent to which teachers are using it as an integral part of their teaching. The study aims to answerif the physical distance to the school library is affecting teachers' ways of working with the library, if it affects thecollaboration between teachers and librarians and finally if teachers that are using a school library outside theschool premises are doing so less as an integral part of their teaching compared to teachers that have access to aschool library within the schools premises.The study is based on qualitative interviews with six teachers in the intermediate stage of the nine-yearcompulsory school, of which three have access to a school library within the school premises and three haveaccess to a school library outside the school premises. The two groups of teachers are compared in order to findout if there is a connection between distance to the school library and the usage of it. Loertscher's school librarymedia program and teacher taxonomy have been used as a theoretical framework.The study shows that the teachers who use a school library within the school premises have a bettercollaboration with the librarians than the ones who use a school library outside the school premises. The studyalso show that theese libraries are an integral part of the teaching to a higher degree.

Varför måste de stora bara bestämma allting? : En studie om barns delaktighet på folkbiblioteket ur barnbibliotekariens perspektiv

A vivid democracy requires participation from those who live in it, including children. Unlike adults, children have special laws and regulations to ensure them their democratic rights. Librarians? decision on what to buy makes an impact to someone else, which puts the librarian in a hegemonic position. Therefore, the purpose of this bachelor thesis is to, out of the child librarian?s perspective, view children?s participation at the public library in the matter of purchasing literature.

Den europeiska exekutionstiteln : En studie av förordning (EG) nr. 805/2004

Increased trade and exchange within the European Community has brought with it the need for less restricted circulation of judgments. The situation has improved greatly due to the enactment of Regulation (EC) No. 44/2001 on jurisdiction and the recognition and enforcement of judgments in civil and commercial matters (the Brussels I Regulation).Despite recent improvements the proceedings are still time-consuming and difficult. Many creditors refrain from having judgments recognized and enforced as the proceedings cost too much time and are too time-consuming. On January the 21st 2005 a new Regulation entered into force, Regulation (EC) No.

Installation av övervakningssytem ombord på fartyget M/S Andromeda

This report is regarding an electrical installation of an alarm system on a post fishingboat called Andromeda. The background of the installation was an earlier andinadequate alarm system that led to a motor failure. The ship was taken out of serviceand was sold to Björn Magndahl who rebuilt it to a yacht.The project was conducted partly by developing the existing systems, partly bydocumenting the work by means of electrical blue prints. Except the alarm systems, aninstallation of the frequency control unit for the bow thruster was installed.The installation was working fine and the outcome of the documentation was handedover in a form of a binder during the test drive of the systems and the assignment wasapproved..
