Empirisk studie av den radiella förspänningskraftens variation i klassiska skärskruvförband
In this study, the pre-tension force in an insert screw connection are examined in order to establish a greater understanding of the system and to facilitate the process of making new metal cutting tools. Certain especially significant design variables such as the offset, the length of the contact thread and the shank length above the threaded hole, are selected to be closely examined. A comparison of the influence on the pre-tension force between threaded holes made with a worn, versus new, threading tool is also involved in the experiment. The study is limited to handling the screw sizes M2,5 and M3,5. The results show that a regression model, with good approximation, can be fitted to the measured values.

Sex i skolbiblioteket : Kunskap, makt och konstruktionen av sexualitet på svenska skolbibliotek
The purpose of this essay is to investigate the construction of sexuality in Swedish school libraries through the lens of Foucault?s concept of power/knowledge. Five libraries were investigated, using two kinds of method: discourse analysis of titles, classification codes and subject headings of sex education materials, and qualitative interviews with librarians working at each of the libraries. Most sex education materials were classified within the medicine section, illustrating the continued authority of medical discourse in matters concerning sexuality. Books for younger audiences were often written for either boys or girls, reproducing a binary understanding of gender.
?e du me på webbsex?? : En studie av kön/genus och sexualitet på ett Internet-community riktat till tjejer.
The thesis examines how sex/gender and sexuality are represented through text and images within the Internet community Sylvia whose primary target group is girls. Through an examination of the aesthetics, the member rules and the choices that constitute the framework for the site, the study observes Sylvia as a cultural context. In relation to this setting, the ten most visited member profiles at the time for the study are more closely examined. These profiles are studied from a constructivist view of sex/gender and are analysed from the perspective of feminist and quee r theory as well as in the light of feministic debates concerning sexuality and erotica. The thesis shows how Internet as a forum and the non-heterosexual context Sylvia open up for a constructivist understanding of sex/gender and also leads to a questioning of "masculinity" and "femininity".
Den transvestitiska förklädnaden : en tolkning av androgynitet i Virginia Woolfs roman Orlando.
AbstractThis paper is an analysis of Virginia Woolf's novel Orlando. My rendering of the novel is inspired by queer-theory and in particular the theories of Judith Butler. In my interpretation I have put my focus mainly on androgyny and transvestite disguise. The purpose of my analysis is to create an understanding of the theme of androgyny in Orlando and see how it relates to the writer's feminist approach. I?ve also used concepts like transvestite disguise and cross-dressing to interpret the main character, Orlando's constant changes of clothes, between female and male clothing.

En bild säger mer än tusen ord, eller?: en studie om inferens
Without being aware of it, cognitive processes continuously take place in our heads. We are forced to fill in the information gaps that we meet in our everyday life in order to create an understanding and to form a whole, and that?s where the importance of inference comes in. To create inference implies creating meaning from something that is not explicitly given. Having knowledge about this process offers great possibilities, while not taking it into account may involve risks.

Tillfrisknande och användning av hästar med fång :
Laminitis has crippled horses through times and many cures have been used to
treat it. Since the mechanism of the disease is yet not fully understood, treatments
are only ways to alleviate the pain and at best, slow down the pathological process
enough to make time for improvement. This paper is a retrospective study of 71
horses treated by a protocol at Hästsjukhuset Strömsholm. The protocol implies
three visits at zero, five and fifteen weeks. At each the horse is evaluated and
treated by a veterinarian.
Förtroende och tillväxt - det kausala sambandet
In this essay I examine the causal relationship between confidence in institutions and growth in Sweden 1989-2002. By examining the causal relationship between these two variables, valuable indicators of the causal relationship between trust and growth can be obtained. The institutions which are used in this essay are chosen according to the theory on institutions for public administration building trust and social capital. The chosen institutions are primary schooling, the police and medical service. A Granger causality model is used to measure the causal relation and the results from the tests show that there is no causal relationship between growth and confidence in institutions.
Faktorer som påverkar kapitalstrukturen i nordiska fastighetsbolag
The bachelor's thesis is to examine the explanatory factors affecting the choice of capital structure in real estate companies. The analysis is based on data collected from the main financial reporting from 2007; all listed real estate companies listed on Swedish, Norwegian, Danish and Finnish stock market. Based on previous research and theories, we have defined five independent variables that are linked to the debt ratio, which are: profitability, growth, firm size, cost of debt and operational risk. The statistical tests have resulted in that we can say with certainty that profitable firms tend to have a lower debt to equity ratio. We can also say with certainty that property companies with high interest costs have a high level of indebtedness..
Fortkörning - en inkomstfråga? : En studie utav inkomstens påverkan på benägenheten att köra för fort
The purpose of the thesis is to investigate whether a higher income make individuals more likely to exceed the speed limit. In addition to income the variables age, sex, perception of the speed of the average driver and offense history for the last three years are taken into account.The method used is based on a survey performed at the mandatory annual motor-vehicle inspection (Bilprovningen). 177 individuals were asked to participate, of these, 124 completed the survey which in turn left us with 117 usable observations.The analysis is based on two forms of regression, a linear regression and an ordered logit regression to confirm the results for the ordinal data.The final model indicates a result where income and age are statistically significant. Sex is considered insignificant for our data material and is excluded from the model. Age has a negative effect on the propensity to exceed the speed limit while income has a positive effect.
Sociala relationer i ett socialt media : - En kvantitativ studie över 151 gymnasieelever i Kalmar och deras Facebook-användande
The aim with this study was to find out how young people at age 16-19 years in Kalmar, Sweden use and interact through Facebook. The questions in our questionnaire were based on three themes, these are; friendship relations on Facebook, what influence Facebook has on young people and how they choose to present themselves on Facebook. The theory that was applied on this study is of social-psychological kind. We chose the theory because we figured it would be suitable to further explain and dispute the aim of the study. The result shows that many different variables can matter in a study like this. We chose to look at a few, such as for example sex and age and we found out that there is a great difference between the way girls and boys use Facebook and how they choose to present themselves in this social media. Another conclusion that our study led to is that Facebook is an important tool for young people, in the meaning that they use it since it makes it easier to communicate with their friends and it also strengthens their relationships with their friends. Keywords: Facebook, Young people, Friendship, Facebook and Social Relations, Facebook use among adolescents & Facebooks? impact on adolescents..
