Organic Light Emitting Displays (OLEDs) are a new type of thin emissive displays predicted to possess superior properties to existing techniques e.g. Liquid Crystal Display (LCD). The main advantages are low power consumption and a thin display structure. This report contains an explanation of the emissive OLED technology, its functionality and the physics of the organic layer structure in an OLED. The technology is described with respect to the two classes of organic materials used in displays, small molecules and conjugated polymers.

Fall accidents are a big problem in the construction industry today and stand forapproximately 23% of all accidents. Skanska is a construction company that has avision toachieve zero accidents. Eliminating fall accidents is one step on the way towards theirvision. The state of Skanskas fall safety has been analyzed in this thesis to show whichimprovements are possible in fall safety.A literature study has been performed in which Arbetsmiljöverkets (The Swedishwork environment authority?s) laws and rules, together with Skanskas own rules havebeen studied.

The efficiency of the harvesters work is more often reviewed, than the work of the forwarders. In a local Stora Enso office the differences between the harvesters reported volume of timber, and the actual volume delivered to the industry had been noticed. Therefore, the decision was made to do a review on the forwarders work. The review was conducted together with a worker from Vmf Qbera, who is working daily with wood measurement, in order to get a valid evaluation of the logs. Eight sites were included in the survey, and on each site 50 logs were marked. Approximately one third of the marked logs were pulpwood, and the remaining logs marked were timber.

As a hibernating species, the brown bear spend most of the winter months in a den as astrategy to avoid unfavorable conditions. The denning period is a vulnerable time for bears,making them unable to flee disturbances without losing valuable amounts of energy. Brownbears' wariness of humans and avoidance of anthropogenic disturbance often steer denningbears away from human infrastructure, and bears thereby avoid possible disturbance and itsassociated energetic costs. This study was carried out to test the hypothesis that bearsdenning closer to infrastructure select more covered den sites to compensate for the closedistance. Dens from 32 individuals were visited and analyzed in terms of sighting distance(a measurement for den horizontal cover) and habitat ruggedness, in relation to distances toinfrastructure.

The aim of this masters thesis is to examine the synthesis and the structure of the main class for linguistics F in the Swedish classification system SAB. We want to find out whether F has developed towards a more faceted structure or not. Our theoretical perspective is based on fundamental principles for modern classification. To carry out our investigation the first, the fourth and the seventh edition of SAB is analysed and compared. The results of our study show that the main class F has become more faceted and therefore the possibilities to use synthesis have increased.

In Sweden there are about 4 million hectares of bare peat (mire). This land has great potential to be transformed into productive forest land, provided drainage is carried out and, in some cases, even fertilization with ashes. Drainage of mires is necessary because the high groundwater table prevents trees from growing due to reduced oxygen availability. Some of the key nutrients that trees need to grow appear in too small quantities in mires, especially potassium (K) and phosphorus (P). Ash from the combustion of biomass contains these elements and is therefore suitable as a fertilizer.

Barley is one of the most important cereals cultivated in the Nordic countries. Climate change brings warmer and moisture climate which favors fungal diseases. In the cropland barley can be seriously infested with hard fungus attack. Since it is important that the yield bears a high quality it is of great importance to find varieties more resistant to attacks.Pathogenesis-related (PR) proteins are stress proteins induced in the plant in response to infection and abiotic stress (van Loon, 1997). PRs are shown to have antimicrobial activity differing between bacteria, fungi and oomycetes (Tandrup Poulsen, 2001).

Abstract Author: Kristin NäsTitle: The technology society?s love letters ? a qualitative analysis of communication through internet dating.Level: BA Thesis in CommunicationLocation: University of KalmarLanguage: SwedishNumber of pages: 53 Keywords: communication, dating, web dating, gendering talk, interaction, flirting, the internet, contact, communities.Summary: A qualitative study on the subject of internet dating and how people using internet dating chooses to present them self and how they choose to communicate with others to create contact. Internet dating is a phenomenon that is continually growing. 2 million people in Sweden are singles today and more than half of them have tried internet dating at least once. The purpose of this study was to research the way people choose to present them self and how the communication on an internet dating site is used.

Bark-stripping by red deer (Cervus elaphus) cause extensive damage to economically valuable spruce trees (Picea abies) in Swedish forests. The underlying causes for bark-stripping are not fully understood, and the frequency and severity of damage unpredictably differ between regions. In this study, I investigated if landscape structure (e.g. agricultural dominated landscape opposed to forest dominated landscape), forage availability, population density and disturbance (e.g. roads and settlements) affect bark-stripping frequency.

The design regulations of Boverket (BKR) have long been the mandatory standard for construction design in Sweden. However from the end of the year 2010, the BKR will be replaced by the European standard Eurocode (EC). The transition to EC has been delayed and it is not until the second of May 2011 that the use of EC will be mandatory. Because EC and BKR differ from each other it is highly interesting to investigate and explain these differences.The purpose of the thesis is to compare the two standards and investigate how they give different results or not for the dimensioning of structures of steel with associated loads. The current project HVC (Pets Science Center) in Uppsala is used as a model for the design of the steel structure used in this study.

Since the end of the eighteenth century forest damage caused by the pathogen Gremmeniella abietina has been observed and documented. During the latest epidemic in Sweden more than 480 000 hectares forest land have been injured and this has lead to considerable economic losses. For the pathogen to succeed with infection, spore dispersal and colonization the right environmental conditions is required. The aim of this paper is to describe the diseased stands using site and stand characteristics and to evaluate the effect of these variables on the disease incidence. Further, the thinning performed during the time for spore dispersal and its relationship to injured stands is examined.

This study aims to determine whether pupils, students and teachers at various music schools feel that there is a difference in status between different music styles/genres, and if this has an impact on the individual level. The survey was conducted with a digital survey that was e-mailed to junior/high schools with music profile in the Stockholm area and to all the teachers and students at the Royal College of music in Stockholm (KMH). Due to low participation by students and teachers from the junior/high schools the students and teachers of KMH became the main object of the study. The results shows that a majority of the main group of this study feels that there is a difference in status between different music styles/genres. The study also shows that half of the participants believe that the difference in status affects them on an individual level.

This report deals with life-history variation for Eurasian perch (Perca fluviatilis L.), with special emphasis on age and size at maturity in females, in perch populations that have changed in size distribution. The collection of fish samples was made with multimesh gill nets year 2011. The perch?s length, height, weight, status of gonads has been analyzed, and by observing the opercular bone the age has been determined. In two lakes close to Umeå in northern Sweden, Fisksjön and Ängersjön, the live-history traits of perch have been studied.

The purpose of this bachelor thesis is to study, describe andimprove the understanding of voluntary driven libraries. How doesthe library staff view their role? How is the library operationworking in respect of economy, organization structure and systemsof rules? Research methods I used were semistructured interviewsand document research.The theoretical framework was based on Joacim Hansson´sdiscussion about libraries in a local community, Henning Bang´sdiscussion about organization culture and the Swedishgovernment´s non- profit advisory group`s discussion aboutvoluntary work.The results of this study shows that the library staff are enthusiastsmotivated by a wish to spread literature to people who find itdifficult to visit municipal libraries. Other motives for theirvoluntary work is the opportunity for being a part of a socialcommunity, to be surrounded by books and to activate body andsenses. The results of this study also shows that the voluntarylibrary system differ from the traditional, municipal library systemconcerning economy, organization structure and set of rules..

AbstractInom forskningen kring personliga hemsidor på Internet har fokus främst riktats mot identitetskonstruktion, hur jaget presenteras och de psykologiska och sociologiska orsakerna som ligger bakom. Min studie tar ett steg ifrån detta och integrerar studiet av den personliga hemsidan med studiet av den politiska hemsidan. Jag undersöker relationen mellan det personliga och det politiska på svenska privata feministiska hemsidor. Jag har intervjuat fyra skapare och analyserat sju hemsidor. Sammantaget utgör min studie en empirisk neddykning i de svenska privata feministiska hemsidor som finns tillgängliga på Internet anno höst 2003 och vår 2004.
