Joniserande strålning, i dagligt tal oegentligt benämnd radioaktiv strålning, förekommer naturligt och utgör en hälsofara för allt organiskt liv. De viktigaste källorna till sådan strålning är radon som finns i varierande mängd i bergrunden, sådant radioaktivt material som finns i all materia (t.ex. Kol-14, Kalium-40), strålning som uppkommer i samband med mänsklig aktivitet (medicinska tillämpningar, kärnkraft, kärnvapenprov) och den kosmiska strålningen. Av dessa ökar den kosmiska strålningen med ökad höjd över havsytan, men samtidigt avtar den sammanlagda stråldosen från de andra källorna något. Sammantaget sker dock en viss ökning av stråldosen med ökande höjd.

The purpose of this study is to examine how participants perceive virtual agents shown on a computer display. In particular, it is explored to what extent participants transfer gender and attraction stereotypes that are commonly applied in the physical world to virtual agents. Previous related studies have often explored only text or voice interfaces, without any visually appearing agents, and here indeed found evidence for a transfer of gender stereotypes. Our hypothesis was that the addition of a visual agent interface would reinforce this effect. The results support our hypothesis that participants transfer human gender and attraction stereotypes onto virtual agents, as well as that these processes are affected by the visual representations of the agents..

The aim of this study was to describe and analyze if and in that case how project Speaking English contributes to improved skills in English to pupils in reading and writing difficulties. The project started out in order to give pupils in reading and writing difficulties an alternative to the regular English teaching. The study was carried out in two nine-year compulsory schools. We have conducted interviews with both teachers and pupils to see what they think about the project. According to the teachers we interviewed Speaking English contribute to improved skills for the pupils and they also believe that their chances to pass the 9th grade will increase.

This report is the written documentation of a project work carried out at the Division of Engineering Materials at Luleå University of Technology in cooperation with Seco Tools AB. The project deals with the analysis of residual stresses in Ti-Al-N thin film grown on WC/Co cutting inserts. The composition of Al varied from 0% up to 75%. Increasing the Al content in the Ti(1-x)Alx N compound improves the compressive residual stresses even after annealing of the material. The experiments have been performed in a high temperature x-ray diffractometer (HTXRD) where the interplanar atomic spacing was determined in-situ and subsequent converted into stresses.

The purpose of this study is to examine the expiration day effect on a stocks volatility due to stock option expiration, which is every third Friday in the month on Stockholm stock exchange. Volatility is the standard deviation of a stock. It measures the uncertainty about a stocks future movement. When volatility increases, the chance or probability of a stock going up or down increases. It?s a common rumor among stock traders that stock volatility tends to increase nearby expiration day.

This thesis was conducted at SverigeGrepen in Vänge-Körlinge, Uppsala, Sweden.SverigeGrepen is a family business that develops and manufactures a few different parts of different kinds of products. My task is to come up with a good idea that facilitates the coupling of trailers, i.e. from an idea to a fully functioning prototype. The product is intended for use by all customers for all kinds of trailers. The actual goal of the work is to develop a full prototype that you can install and use in the easiest way possible, a prototype that follows the specifications.

This Bachelor of Science thesis was carried out at Metso Panelboard AB, located in Sundsvall, Sweden. The work lasted for 10 weeks and began at the end of February 2007. Metso Panelboard is one of the leading suppliers of complete lines, single machines, engineering knowledge and after-market services to the fibreboard industries. The task involved building a 3D-model of a dryer cyclone in the CAD-program Pro/ENGINEER. A dryer cyclone is the part where the tree fibres are dried in the process of manufacturing fibreboards. Currently, it takes about two weeks to draw a dryer cyclone. By creating a 3D-model of it, which should have the functionality to be generated to different sizes, the goal is to decrease the drawing time to about 20 hours and to increase the quality of the work. This report includes the fundamental theories behind the manufacturing of fibreboards with focus on the dryer cyclone.

The purpose of this thesis is to look into the knowledge city concept and the preferences and requirements of companies on such a city. Furthermore, suggestions of ideal conditions in a knowledge city are proposed. The thesis has been conducted through a qualitative approach where a deductive procedure has been implemented. In order to examine knowledge cities, Barcelona has sketchily been looked at as an early example of a knowledge city, whereas a more exhaustive observation of Copenhagen was conducted. Since the concept of knowledge cities is a rather new phenomenon, models from several disciplines constitute the theoretical framework.

The first official Islamic bank was established in 1975. The characteristic of an Islamic bank is that the bank is based on an interest free system. The interest free system is a requirement for an Islamic bank. The Islamic bank system is based on Sharia laws which are laws that are followed by Muslims and it is based on the text from the Quran. The Islamic Banks had a rapid expansion between 1993 and 2003, the expansion was about 23 percent and since 2003 have the expansion been about 20 percent.

Thepassword encryption part focuses on examining different hash functions executionspeed, the result shows that none of the examined hash algorithms is suitable fordirect use.

Suicidology deals a lot with taking into consideration significant symptoms, risk factors and establishing causal relationships which inevitably are very important for suicide prevention. But do we understand the suicide attempters better thereby? The aim with the study is to elucidate the meaning of the lived suicidal experience that is expressed by participants on an Internet forum. Ten participants' texts which concerned own suicidality were chosen out from this Internet forum and were analyzed and interpreted on the basis of a phenomenological hermeneutical method inspired by Ricoeur (1976). The result established twelve themes that with the aid of Heidegger (1993) and Derrida (1978, 1991) led to that the following conclusions could be drawn about the meaning of the suicidal lifeworld: suicidal concern and care in itself reduces the sense of identity, practical suicidal doing in itself reduces the world, sense of identity is more affected by the future than the present and the past, the death is escaped from through a calculating determination to have the death at one's disposal, inability to turn away from the death increases oscillating between states of emotions, the surrounding world's requirement to avoiding death becomes to a compulsion to isolate one self; and finally: to both feel anxiety in front of one self's own death and dread when escaping from it..

Målet med detta arbete är att bättre förstå hur riktlinjer ska skapas och användas. Utgångspunkten har varit att media uppmärksammat ett flertal incidenter där främmande människor tog oönskad kontakt med olika förskolor i Karlskronaområdet. Författarna ville då se över hur kommunen arbetade med frågor om yttre hot vilket medförde att arbetet utmynnade i ett försök om att bättre försöka få förståelse för riktlinjer och dess användning då kommunen vid arbetets start saknade riktlinjer för yttre hot av denna typ. Metoden som använts är av kvalitativ art i form av intervjuer med några säkerhetsansvariga för förskolor i andra svenska kommuner. Resultatet av dessa intervjuer tillsammans med kompletterande material från generella tillvägagångssätt för identifikation och analys av säkerhetsproblem resulterade i ett förslag på arbetsmetoden vid skapandet av riktlinjer samt en påminnelse om att se över befintliga riktlinjer för yttre hot..

The aim of this qualitative study was to give an deeper understanding of how employees in the engineering industry experienced health education and how they understood and gave meaning to the terms health and health education. The study was based on interviews with eight men and women who participated in a health education project which had been held on their workplace. When the study took place the interviewees were in the age between 28 and 58 years. The results indicate that the employees understood health as a combination of both physical and psychological factors. The positive aspects described by the interviewees based on their experiences from the project were increase physical activities and that the project had helped them to get a better diet.

Participation is central to the concept of democracy. The role of the civic participation varies with different types of democracy, but a fundamental requirement is that the participation is free and equal. In spite of this, there are significant differences between possibilities to democratic participation in Sweden today.This essay seeks to understand how disability, historically and still today, is constructed as a social deviation from normality, and is constructed to Otherness.One way to regard freedom and equality is to examine the personal autonomy, the legth to wich a person decides her/his roles and activities in abcence of external limitations. Personal autonomy is theoretically central in deliberative and strong democracy, but should reasonobly be a demand for the fundamental definition of democracy.The explanation to why the lack of personal autonomy is accepted, is that the construction of Otherness results in that the persons are categorized and are given simplified characteristics, and are thereby not accepted as equivalent people.In the inteviews conducted, seven politicians contribute both whiteness, pathological discourses regarding disability and ideas of normality through discussing democracy, participation and disability. Simultaniously, they express interest and an awareness on the majority's power and symbolic violence on the minority..
