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.

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.

Detta kandidatarbete undersöker gröna tak i urban miljö. Gröna tak är i denna uppsats ett begrepp och samlingsnamn för vegetation på byggnaders tak i olika former. Trenden för gröna tak pekar uppåt, främst utomlands men även i Sverige. Emporia i Malmö som är ett av Skandinaviens största köpcentrum är byggt med ett så kallat grönt tak. Detta tak anlades dock på initiativ av byggherren och inte efter kommunens beslut. Huvudsyftet med uppsatsen är att undersöka om och i så fall hur kommunen kan planlägga gröna tak. Fördelar och nackdelar med det gröna taket kommer också att utgöra en del av uppsatsen.

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).

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.

Hur publika displayer skall utformas och anpassas efter sin miljö på bästa sätt är ännu ett outforskat område. I takt med att miljöfrågor blivit än mer aktuella i dagens samhälle har det också etablerats ett behov av att förändra vårt beteende exempelvis i form av energieffektivisering. Syftet med denna uppsats är att undersöka hur en publik touchdisplay för elvisualisering skall utformas för att vara förståelig, intuitiv och säker från publik genans. En användarstudie i form av en utvärdering av en interaktiv touchdisplay kallad Urban Energy monterad i Göteborg har gjorts under ledning av Interactive Institute Swedish ICT. Touchdisplayens primära syfte är att uppmärksamma förbipasserande på stadens elförbrukning och uppmuntra till energimedvetenhet.I denna studie rekryterades 17 förbipasserande deltagare villiga att testa denna display med hjälp av två uppgifter och en enkät.

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.

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.

Att gestalta naturliga landskap i en urban situation handlar om att förstå parallella processer som pågår samtidigt; att se platsens förutsättningar och biotopens preferenser. Genom det skapas ett nytt sammanhang där beståndsdelarna blir aktiva i flera olika situationer och skalnivåer. Denna tes har jag fått möjlighet att undersöka och fullskaletesta i TAKLANDSKAPET Sveavägen 44. Arbetets syfte är att sammanlänka förståelsen för hur man kan applicera hela biotoper i ett sammanhang som gör att den levande biologiska delen av projektet bidrar aktivit till upplevelsen och till det arkitektoniska utrycket och formgivningen av platsen. Slutsatsen är att man inte behöver se biotoper enbart som passiva byggelement eller komponenter. Det är biotoperna i sig som bär och leder konceptutvecklingen för idé, möjliga program och den potentiella inneboende formen. Strategin att reducera och platsanpassa komponenterna ger också svaret i en annan skala: Fråga platsen vad den vill vara och du kan samtidgt se mönstret i ett större sammanhang. Om man lyckas med formgivning som en öppen process med möjliga förändringar, utan att idén går förlorad, har man skapat ett öppet system; ett fraktalt system både i tid och rum. Jag tror och hoppas att TAKLANDSKAPET Sveavägen 44 innehåller dessa kvalitéer och att arbetssättet kan inspirera till liknande angreppssätt i andra projekt. Att se vad man har, för att få det man önskar. I alla skalor... LÄS LANDSKAPET, FÖLJ NATUREN, ÄLSKA LIVET..

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..

Sustainable development is a concept that has been interpreted in a multitude of ways in different contexts. This essay argues that the discourse of "ecological modernization" has strongly influenced the way in which the concept of ?sustainability? has been constructed in Swedish environmental policy. This interpretation of the concept of sustainability offers the possibility of combining economic growth with ecological sustainability which stands in contrast to the assumptions of Deep Ecology and Green Theory. The aim of this essay is to explore how the concept of sustainability is being formulated in environmental policy both on a national level and in the city of Malmö.Considering these issues in a specific context, this essay focuses on city planning that is as an important instrument to promote urban sustainability both on national and local levels.

Is it possible that by planning in a more sustainable way when building a new area, we can improve our environment?Most environmental problems are created in cities and therefore they should hold the solution. Through a more ecological urban planning a better foundation for sustainable housing could be created.This report follows the process in coming up with a proposal for a master plan for an area in Odense, Denmark. By going through principles for sustainable urban planning made by different organizations and persons and from these extract main principles, a background is founded to continue the proposal from.Denmark works a lot on expanding their green areas, maintain the existing ones and recreate what?s being destroyed as cities expand.
