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.

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).

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.

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..

Computer Forensics investigations have become more and more common while investigating IT-related issues. From experience, hard disks, USB thumb, memory sticks contains information that might be useful. Computer Forensics is regulary conducted by Police, Customs, Tax investigators but also within private companies and organisations. However, there are areas within the storage device that are not part of the organisied structure that a file system gives. The reason for that might be that the information has been erased by intention, a virus destroyed the file system and so on.

Denna uppsats undersöker huruvida den dramaturgiska strukturen är en förutsättning för att en situationskomedi ska fungera väl ? det vill säga, vara underhållande och locka till skratt. I en komparativ analys av den mycket väl fungerande amerikanska situationskomedin Friends och den mindre bra svenska situationskomedin Svensson, Svensson framkom dock inga större strukturella brister hos något av analysobjekten. Följaktligen är inte den dramaturgiska strukturen avgörande för slutresultatets förmåga att roa. The aim of this study is to find out if dramatic structure is essential to the sitcom's ability to entertain and make audiences laugh. This study is a comparative analysis of the more humorous American situation comedy Friends and the less humorous Swedish situation comedy Svensson, Svensson.

When the Iron spirals investigated in this paper saw the light again no one looked at them as nothing more than decoration. It was first during the 2011 excavation in Old Uppsala that the symbolism of the items no longer could be ignored. The spirals of Old Uppsala lay along the walls of the great hall, which stood upon one of the human constructed plateaus in the area. The hall had been burned down and then cleared of all lumber. Then the iron spirals had been placed in the positions and then everything was sealed with a layer of clay.A study of the artifact began with the purpose to contextualize and interpret the iron spiral.

Den nya standarden Eurokod kräver omställningar på byggprojekteringskontoren i det hänseende att personalen måste lära sig att använda och följa denna standard. För knutpunkter i stål har det hittills funnits stöd i form av beräkningsmetoder och handböcker, men ännu har inte någon utförlig hjälp om hur man hanterar dem med Eurokod utkommit. Trots att dimensioneringsprocessen av knutpunkterna är mycket viktig vid projektering av stålkonstruktioner är processen långsammare än den kan vara. Därför vore det bra om man fann ett enklare och snabbare sätt att dimensionera knutpunkter i enlighet med Eurokod.Intervjuer har visat att dimensioneringsprocessen hittills fungerat så att beräkningarna sker för hand av en konstruktör enligt BKR:s regler, för att sedan modelleras i 3D av en projektör som slutligen får sina ritningar granskade av en tredje person.Genom fallstudier av standardknutpunkten BP1 söktes en förbättrad dimensioneringsprocess jämfört med den som intervjuerna beskrev. I fallstudierna dimensionerades BP1 för hand och med programmen Autodesk Robot Structure Professional Analysis 2011 och modellerades med Tekla Structure 16.0, hela tiden i enlighet med Eurokod.

The aim of this thesis is to describe the rise of the Tea Party movement in the United States. By using a known theory within social movement studies, the political process theory, this thesis look into the factors that could have played a role in the rise and fast mobilization of the Tea Party movement. The political process theory consists of three parts and hence looks into both the political structure of, in this case, the United States, how mobilizing structures have been used and into the cultural framing used by the Tea Party to create their identity. In order to bring structure to the thesis, the three theory parts have been transformed into analysis models. These give a very good idea of all the factors that could have played a part and therefore also a good way to describe the rise of the Tea Party movement.The research confirm what the political process theory says, that the Tea Party movements rise came at a time when there were a mix of factors at play, both structural and cultural, creating an opportunity that the Tea Party took.

The issue about how Scania shall perform HVAC tests in the climatic wind tunnel CD7, which Scania is about to complete by year 2013, has resulted in four test methods for truck HVAC and also a test method structure. The test methods have been chosen to focus on sun, snow and rain simulations. These are adapted and developed according to what should be tested and to what can be tested in CD7, which has been the object. With CD7 different climates can be simulated in a controlled environment for complete truck level, from desert with high sun load to arctic cold and snow.The test methods represents a basis to start from, for designers and test engineers which make the testing more repetitive as well as time eventually can be saved. Before the test methods can be applied they must be verified as they are based on theoretical and empirical assumptions.

In order to fully grasp the phenomena 'City' we must understand its political structure as an integrated part of its physical structure and vice versa. This thesis focuses on one crucial element of the City, the public space, and discusses it in relation to the public realm, or sphere, of the City. The aim is to see if it is possible to conceive public space as a spatial dimension of power, and if so, how to analyse this. With the help of the theoretical tool of two ideal types of the configuration of public space, "The city as civic public life" and "The city as authoritarian control" an empirical study is carried out on the case of Prishtina, capital of Kosovo.Conclusions made are that function and use of a city's public spaces can be understood in relation to changes in the political climate of the society. Furthermore, a void in the asset of concepts offered by the ideal types is found ? and therefore also need for new concepts to describe and understand a public space undergoing a dynamic transformation, as being a part of a city in political transition..
