Dikesavståndets inverkan på såtid och skörd

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.

Hållbar stadsutveckling? : Problem och målkonflikter i planeringen av Hagastaden och Norra Djurgårdsstaden i Stockholm

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.

Speaker Park : om ljudsättning av utemiljöer

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.

De stenbundna skeppen i tra?dens skugga : En studie kring skeppsformade monument fra?n yngre bronsa?lder pa? O?land

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.

Qualities and supply of suitable dead wood for Ceruchus chrysomelinus and its dispersal pattern in a translocated population

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.

Allt är möjligt hus i Gustavsberg

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 .

USA versus al-Qaida : linjärt tänkande mot asymmetriska metoder - en studie kring den amerikanska problematiken i kampen mot terrorismen

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.

Kunskapens rum - en studie av Orkanenbiblioteket

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.

Anestesisjuksköterskors upplevelser av sin fysiska och psykosociala arbetsmiljö

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.

Cassava as an additive in biomass fuel pellet production :

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).

Att rädda det förgångna : Om Walter Benjamins historiska materialism

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.

Utveckling och konstruktion av dämpare och låssystem för vågkraftverk

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.

Robotiserad produktionsanpassad magnetmontering för vågkraftverk

This thesis work includes studies and simulation how magnetization of the translator in a linear generator for wave power can be automated. The translator is the moving component in the generator that is "dressed" with permanent magnets. The translator is magnetized with rectangle-shaped permanent magnets that are today's strongest permanent magnet type of neodymium-iron-boron (NdFeB).Eight equivalent metal sheets are mounted around the translator. The plates have milled tracks where 106 permanent magnets per sheet are mounted. Today the assembling of the magnets is done by hand, which is a very tedious and time-consuming work.  This project presents investigations about the automation of the translator magnetization theoretically and simulation results are preformed in ABB's robot simulation software RobotStudio. Even robot-held tool was designed that enables the robot to be able to magnetize the translator in a simple manner.  The investment cost is roughly 1.5 million SEK. With an economic life-time of five years, the investment costs are estimated to 24000 SEK / month.  According to the calculations, this project is very motivated to implement, as it provides savings up to 17 000 SEK per translator which is 10.2 million SEK assuming that the robot cell is operating at full speed the whole year.According to this thesis work the result is a 4x9 meter cell with two industrial robots of the type ABB IRB6650S.The cycle time to magnetize one translator was calculated to about 10 hours.This prototype of project can possibly be implemented in a full-scale production line and performed according to the calculations and simulations presented in the report. Further work is suggested to improve the tool.Lyssna .

Integrerad arbetsprocess mellan projektör och konstruktör, För effektiv och kvalitetssäker projektering med Tekla Structures och SAP2000

The purpose of this work is to design and construct a device able to measure the mechanical attrition of oxygen carrier particles. Those particles are used in chemical looping combustion and in the present situation there is a lack of knowledge in how the attrition process work and in which extension. To find already tested solutions trying to answering this problem a literature study wascarried out and the best solution found was the so called Grace-Davison Jet-Cup method. This method is supposed to emulate the attrition caused by a cyclone separator and its advantages are that it is possible to use small test amounts, 5-10 g, and a thirty minutes long test will be enough to acquire useable results. An device was designed based on the Jet-Cup method with some slight modifications.
