The purpose of this thesis is to investigate if vacuum insulation panels are a competitive alternative to traditional insulation.Vacuum insulation has been used as insulation in buildings in Germany and Switzerland for a few years. In Sweden the high-performance insulation material is mainly used in refrigerators, freezers and vacuum thermoses. The development is proceeding well and vacuum insulation is becoming more common in the construction industry. Since it is a relatively unexplored material on the market there are many flaws and problems with the material.The questions we have chosen to answer in this report include an increased knowledge of vacuum insulation, various problems that may arise when handling/installation and the pros and cons of vacuum insulation compared to standard traditional insulation.The methods we have chosen to use in this report is a literature study, interviews with various suppliers and manufactures and calculations to show the differences between traditional and vacuum insulation. Vacuum insulation is 5-10 times better insulation than standard traditional mineral wool insulation, mainly at the beginning of its lifetime.Vacuum insulation panels (VIP) have a service life of approximately 50 years, whereas traditional insulation has a service life of approximately 100 years.

All arable land in Sweden need a proper drainage for an effectively agriculture to take place. Of all arable land in Sweden, about 50% is naturally drained and 50% need artificial drainge. More than half of the tile drained area is in need of new drainage or renewed drainage. A good drainage improves farming and crop growth and increases the opportunity to achieve a high and safe harvest level. Future climate change and agriculture size rationalization will increase the need for good drainage. In this paper, two trials with three drainage distances, performed at Lanna experimental station, were analyzed using a mixed linear model.

EW26 is a Bachelor thesis carried out by students, Jessica Blomberg, Sara Danielsson and Mikael Johansson, during the academic year 2010-2011 at the Innovation Engineering Program of Halmstad University. The project was conducted in close cooperation with Ergosafe AB.Ergosafe develops, manufactures and sells electric sliding windows. Due to the company?s current expansion phase they want to increase their product range. The company has identified a need for large windows that moves vertically.

This study examines how allotment gardens are perceived and used by non-plot holders in Majorna, Gothenburg, with a focus on Sj?bergens koloniomr?de and Slottsskogskolonin. The study is based on a survey of residents and people moving through the area and has an outsider perspective.The results show that both areas are primarily perceived as green spaces and as zones away from urban stress, highlighting their social and recreational value. However, clear differences also emerge. Slottsskogskolonin is more strongly associated with exclusivity and aesthetically appealing environments, whereas Sj?bergen is more often linked to nature, ideological values, and food production.

The major environmental problems that we have today are frequently mentioned in the media today. One example is the ongoing debate regarding global warming and its causes and consequences. There are also several other problems in our society such as segregation and social tensions. Most agree that we must do something to solve these problems and that we must try to achieve a sustainable development for the entire planet. But how should it actually be done and what trade-offs, compromises, sacrifices and changes must be made?The purpose of this paper is to examine how these issues are being dealt with in Swedish city planning.

Ship formed monuments from the Late Bronze Age on the island of O?land, southeast Sweden, have never been thoroughly dealt with in previous research, despite the fact that the region is suggested to have had a key-role in maritime trade networks. This thesis aims to address the ship formed monuments on O?land in relationship to the monuments in northern Sma?land and the island of Gotland. My goal is to discuss how the ship symbolism was practised during the Late Bronze Age in Scandinavia from a new perspective.

This project will search for the sound in the contemporary landscape architecture, an attempt to combine music and land­scaping. In a first stage, I have searched for outdoor environments where loudspeakers are used, and sites with a concious sound design. The project will result in a sound design created for the park Frodeparken in Uppsala, Sweden. In my search for sites and examples of conscious sound, I have talked to the people behind the projects I found - landscape architects, sound artists and architects. Influences from different areas have been essential for me in the project.

The wood-living beetle Ceruchus chrysomelinus is a rare species connected to natural forests. In Sweden, it is red-listed as endangered (EN) and an action plan for its preservation has been done by the Swedish Environmental Protection Agency. In this work I have therefore investigated how a translocation of the species succeeded after 17 years. I aimed to study the species dispersal biology, its substrate preferences and the supply of suitable wood on this site. The study was performed during 2012 in Pansaruddens nature reserve close to Uppsala in Sweden, which is a spruce dominated forest.

In a sequence described in the next paragraphs, I remove the poorly insulated roof of Gustavsberg Porcelain Factory and make new use of its  foundation. The monolith cement slab, once supporting heavy industrial machinery, is now the site of lakes and other movements:The top floor area is split, and a new built volume, one story higher, overtakes the southern half resting on the factory?s basement, digging into it at its western and eastern ends. Striking horizontally, the fissure exposes a long central axis, taking advantage of the factory?s horizontality to articulate vastness .

Syftet med denna uppsats har varit att undersöka på vilket sätt attacker utförda av al-Qaida kanhänföras till begreppet asymmetri och på vilket sätt man kan tolka den amerikanska administrationensrespons på dessa som uttryck för ett linjärt tänkande. Vidare vill jag undersöka vilka svårigheter somkan uppstå i relationen mellan en linjär omvärldsuppfattning och asymmetriska metoder. För attuppfylla syftet med uppsatsen kommer tre av al-Qaidas attacker att studeras. Dessa är: attacken mot deamerikanska ambassaderna i Afrika, 1998, attacken mot USS Cole, 2000 och attacken 11 september,2001. Rapporterna från den amerikanska administrationen efter respektive attack kommer att utgöragrunden i mitt empiriska material.

The aim of this master´s thesis is to explore how a library through it´s spatial distribution expresses, and is an expression for, a view of knowledge. This is done by an analysis of the Orkanen library at Malmö Högskola. Questions posed in this study are: What view of knowledge is mediated through the spatial system and in the shelving of books? What view of learning is expressed in the spatial distribution of functions and artefacts?The theoretical framework of this thesis has two fundamental features. One, which focuses on theories of social space, a part that is mainly influenced by the theories of space syntax.

In this study, the effects of using fine milled cassava stems as an additive in biofuel pellet production was compared to the effects of refined starch addition. The bulk biomass fuel raw material, to which the additive was added, was a blend of spruce and pine sawdust. An experimental design in the factors cassava/starch content, moisture content and material temperature was used. Measured responses were pellet bulk density, pellet durability, amount of fines, pelletizer motor current, pellet temperature, die temperature and CV for pelletizer motor current (a measure of process stability). Each response was modeled by multiple linear regression (MLR).

Health care is increasingly complex, which increases the demand for knowledge and expertise. Despite this, the share of specialized nurses, including anaesthesia nurses, has decreased from 65% to 48% from year 1995 to year 2008, according to statistics from the National Board of Health and Welfare (Socialstyrelsen) in 2010. Studies indicate that there may be various factors in the work environment that anaesthesia nurses, choose to leave the anaesthesia profession. The purpose of this study was to examine how anaesthesia nurses experienced the physical and psychosocial work. The study was conducted as a descriptive study with qualitative approach.

The present essay concerns Walter Benjamin?s thought regarding history and temporality as he articulated it in his last work that was only published posthumously: ?U?ber den Begriff der Geschichte?. The purpose is to analyze Benjamin?s construction of historical materialism and to suggest a reading of it as directed towards an opening of history. For Walter Benjamin, every moment presents itself as a possibility of radical otherness: a possibility for things to be different.

The division of Electricity at Uppsala University is developing a wave energy converter(WEC) consisting of a linear generator connected to a bouy at the water surfacethrough a wire cable called the connection line.During extreme conditions, the wave power plant will experience forces up to 500kN, which lead to unnecessary wear and will ultimately cause the failure of theconverter. To prevent this there is a need for a damper.The wave energy converter works at a maximum efficiency when the translator?sare centered with respect to the stator. Due to tidal movements the position of thetranslator can deviate. There for a mechanical divice that will compensate for this isneeded.This report describes the further development of an earlier project where a tidalwave compensator for a wave energy converter of Seabased AB was developed.
