The first step was todo a literature survey of earlier work on this problem, study the theory ofhydrodynamic bearings and different types of seals and their properties.

The purpose of this study is to investigate how much of the estimated annual electric energy production from Swedish wind power that actually was produced, as well as the history of this agreement over time. The aim is to also examine if there are properties that have caused some group of wind power plants to produce more or less, compared to their estimated production. Operational data on wind turbines collected by the Swedish Energy Agency was analyzed. A survey was made among owners of wind power plants with a nominal power of at least 2 MW. Two different methods for normal year correction of production data were used and compared.

This essay concerns dance as an exhibition object by examining the permanent exhibition at The Museum of Dance in Stockholm, Dansmuseet. Due to its dependence on the temporality and movement of the lived body, dance does not easily lend itself to being exhibited in a traditional exhibition display; and since the live dance performance itself is ostensibly absent at the exhibition display, other means of representation must be relied upon in order to evoke the exhibition visitors? experiences of time and movement as well as the feeling of dance. Starting from a phenomenological first-person perspective, as an exhibition visitor, I present three ways in which such experiences may come about. The cross-section of the experience evoked and the means that trigger them are intermedial, spatial, and performative taking their departure in the visitor?s pre-understanding of dance..

Nuts of all kinds are common ingredients in food. For nut allergy sufferers the frequent use of nuts cause problems and "hidden" nuts in food products may elicit allergic reaction when such foods are consumed. Methods for detecting and quantifying walnut (and other nuts) with high sensitivity and specificity are therefore very important.The objective of this project was to verify the specificity of a rabbit antiserum against walnut with immunodiffusion and to determine the size of the dominant walnut antigens with Western blotting. In addition, a commercial sandwich ELISA for walnut quantification was validated and compared with a qualitative real-time PCR.The rabbit antiserum proved to be less specific but after absorption with cross-reacting nuts and seeds it showed high specificity. The ELISA kit reacted, except for walnut, with pecan and slightly with other nuts and seeds tested.

The purpose of this paper has been to shed light on the ways the history represented at the City Museum of Stockholm can be used in education at the Gymnasia level. I have made use of the following set of questions to attain this purpose: 1) How is the City Museum's activity vis-á-vis the gymnasia organized and what is the purpose of this activity? 2) What positive results do the interviewees see in the collaboration between the schools and the Museum? 3) Why did the teachers represented in this paper choose to make use of the Museum in their education? The bulk of the study is based upon three interviews with the First Curator at the City Museum of Stockholm and two teachers, from Viola Gymnasiet and Skogsgårds Gymnasiet respectively. My method is qualitative and interpretative with hermeneutic features.In my interpretation of the source material I have made use of historian Klas-Göran Karlsson's classifications regarding the needs for various forms of history, use of history, users and functions of results. In this way I have been able to establish how the Museum and the teachers represented in the study make use of the history that is represented at the Museum.

Syftet med denna uppsats var att studera hur tevereklam till kvinnor och till män kan beskrivas. Vi ville uppnå syftet genom att undersöka hur ett företag arbetar med att utforma tevereklam till kvinnor och män: vilka mål samt fördelar och nackdelar de har med tevereklam, hur tevereklam utformas, hur traditionella könsroller eventuellt påverkar utformningen samt om lagar och egenåtgärder har någon påverkan på innehållet i tevereklam. För att uppnå detta syfte gjorde vi en fallstudie på RoxxEmotion Film & Television, ett mindre företag som är en del av Roxx Communication Group AB. Vi utförde en telefonintervju med en av de två personer som ansvarar för tevereklamfilm på företaget. Slutsatser från denna fallstudie visar att det är vanligt att rikta tevereklam till ett visst kön men att tillvägagångssätt vid utformning av tevereklam samt mål, fördelar och nackdelar med tevereklam är lika för reklam till både kvinnor och män.

AbstractThis study focuses on three generations of Kurdish women's view on honor. The study is a qualitative research based on three individual interviews. The aim of this study is to examine how three generations of immigrant women from a culture of honor is influenced over time by the majority culture and its values together with how these women affect each other mutually both consciously and unconsciously within the family. The study is based on two questions: What does"honor" mean to the three generations of women who are Muslim and Kurdish? Did these three generations of women?s idea of honor change over time as they have lived in Sweden? Results of this study have shown that the concept of honor has its focus on the woman's body, sexuality and chastity.

Gastric ulcer is a common disease among pigs in the whole world where an intensiveproduction occurs. It is mainly the upper region, the nonglandular region of the stomach thatis affected. Gastric ulceration is a disease with several risk factors. The factor that seems tohave the largest impact on the development of gastric ulceration is a small particle size of thefeed. The reported prevalence of gastric ulceration differs from 5 to 100 % and it is a largeherd-to-herd variation.

Tree fiber lengths controls properties like strength and smoothness in paper and other wood products. For forest researchers it is of interest to be able to determine the fiber lengths in standing trees. Mo?rling et al. (2003), among others, have developed methods to estimate fiber length distributions in standing trees without damaging them.

The aim of this paper is to investigate who the visitors are at a children's department at amain library in a larger municipality, and for what purpose they use it. We discuss: Is therea difference between various user groups, and if so, how do they differ'? Which library rolesdoes the children's department have? Does the children's department serve as a local libraryfor those who live in the immediate surroundings or as a main library for the whole municipality?The paper is based on a user survey performed in the spring of 1996 at the City Library ofGothenburg. 417 visitors and five staff members were interviewed.The children's department is used by various groups of people, from young children to seniorcitizens. The library roles are, among other things, an independent learning center and formaleducation support center.

Assessment of hearing aids can be done by inventories. The result of the inventories can show the patients need and how the hearing aids works in the patients daily life. The result of the inventories can be influenced by the difference in languages and the cultures. The inventory IOI-HA should not be sensitive to those factors.The aim of this study was to compare and analyse material, method and to report and analyse the result from a pilot study made at Sahlgrenska University.The result showed that IOI-HA is a natural inventory which is able to be used internationally. The four studies in England, USA, the Netherlands, and Germany showed that the psychometric properties are similar across languages and cultures.

The purpose of this essay is to shed some light upon the children who grew up in Sweden after their parents fled the war in former Yugoslavia. Did the parents spread their own opinions about the other ethnicities which they fought against in the war to the children, even though they live in a new country? And if so, was it an act of patriotism for the country they once lived in and who was to blame for the war? Did the children who grew up in Sweden share the same attitudes as their parents? To find out about this we used interviews with four people, all with heritage from former Yugoslavia, Bosnia and Croatia. What we found out was that the thoughts from the parents partially were passed down to their children, even though the children thought that they had formed their own opinions. In this case the thoughts didn?t relate to any kind of patriotism or who to blame for the war, they rather believed that they shouldn?t blame the other ethnic groups for the war.

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.

Sweden has a long and extensive wind band tradition. Today the interest for the traditional instruments is decreasing among children and teenagers. What can this be due to? Which conditions are needed for a functional wind band in the future? The purpose of this essay is to find answers to these questions and at the same time shed light on good examples, where the wind band activity works. To be able to answer the questions have I made four interviews with persons who have a big knowledge and interest about the subject.
