I denna studie har förekomst av progesteronreceptorer i olika typer av primära juvertumörer undersökts med hjälp av immunohistokemi. Dessutom har tumörceller från carcinomcellinjen CMT-U27 odlats i olika cellodlingsmedium och exponerats för olika testsubstanser som binder till progesteronreceptorn (progesteron och RU486/mifepristone). Cellernas receptoruttryck och progesteroninnehåll utvärderades med hjälp av ELISA och tumörcellernas viabilitet analyserades med Colorimetric Cell Viability Test. Av resultaten framgår att samtliga undersökta primära juvertumörer uttryckte progesteronreceptorer. De odlade cellerna hade högre cellviabilitet när de odlades utan fetalt bovint serum (FBS). Efter exponering med progesteron minskade tumörcellernas uttryck av progesteronreceptorer, vilket hämmades av mifepristone.

The mobile revolution is here to stay, and today most people have (at least) one cell phone at home. Some even a PDA (Personal Digital Assistant)as a complement for the simpler tasks at the office, e.g sending e-mail, word processing, browsing the Internet etc. Many business have also given the employees the opportunity to do some of the business tasks inbetweeen customer visits with the help from a cell phone or PDA.Despite all this, the so called Internet connected mobile revolution is often mentioned as a big failure. Maybe because the people in general tended not to use the new technology as much as the companies predicted. This could be because they still haven't learned how it works, or just don't seem to have the need for services provided.After a couple of failures in the development process, almost every cell phone has support for mobile Internet today.

The aim of this master's thesis is to describe the management of free Internet resources in three Swedish research libraries. With the starting point in the increased quantity and importance of these resources, together with reflections on the change of the concept of collection, the thesis shows how and to what extent these freely accessible Internet resources are being integrated in the day-to-day work with collection development. It also elucidates the problems with the free Internet resources from the research libraries points of view. The study is based upon analyses of collection management literature and qualitative interviews with librarians at the chosen libraries. The thesis shows that the research libraries still have not come very far in their work of integrating the free Internet resources in their collections.

The purpose of this thesis is to examine the narrative elements in three of the Swedish artist Karin Mamma Anderssons paintings and try to see what kind of stories that might be hidden in these paintings. I have chosen three different themes as tools for this study. They are: the meaning or the importance of the titles, painting as a medium and the narrative elements or components in the paintings. Furthermore I also use the semiotic method in my analysis based on the ideas of Roland Barthes combined with a feminist theoretical standpoint with a gender perspective. This means my study is based on the reception of these images and what kind of message they might carry.

This thesis investigates similarities and disparities between Swedish and Polish Labour Law concerning dismissals due to operational requirements and group redundancies. The study focuses on three important elements where the employers? liberty is legally infringed upon in a procedure of notice. These elements concerns the legal conditions of notice that must be fulfilled, the rules of the procedure and the rules for employment protection that is granted in connection with dismissals due to operational requirement or group redundancies. In the thesis there is a comparative map that outlines the most important rules within the Swedish and Polish legal systems concerning the subject.

The focus of this thesis is on what is considered to be a suitable foster home. For the study to be carried out an application had to be made to get access to the foster home assessments in a medium-sized municipality in Sweden. With the support of attachment theory and theory of standards different categories have been picked out and analyzed in foster home assessements that have been approved. The conclusion to what is considered to be a suitable foster home is a complex issue, as there are many factors that are interacting. Social workers seem to focus on the importance of a family?s ability to provide some kind of stability and security for a child who is considered to be placed within their home.

Syftet med denna undersökning är att undersöka elevers förståelse av begreppet gravitation. Undersökningen är gjord på elever som läser kursen fysik B på gymnasiet. Många studier har undersökt elevers begreppsförståelse kring rörelse och kraftbegreppet. Min undersökning grundar sig i denna forskning och i empiriska studier. Begreppen och kunskaperna som behövs för att lösa enkätfrågorna är inget nytt för eleverna.

This aim of this thesis is to measure the effect of the user interface in real searches on the Internet through a small experiment. Theories on web and search usability and psychological factors concerning usability were first explored. Then three interfaces were constructed, one "good" that followed usability guidelines and had multiple search functions, one "bad" that completely disobeyed those guidelines and had only a simple and small search field, and one "intermediate" interface that was a mix of the two. The search field was set to different sizes, with the shortest in the "bad" interface, a medium field in the "intermediate" interface and several long fields in the "good" interface. All three interfaces were then attached to the same web search engine, Altavista.

Body esteem is the affective aspect of body image, which is shaped by social experience. Compared with men, women have a more negative body image, which is more frequently correlated with depression and dysfunctional thoughts, especially in the case of eating disorders. The purpose of the present study was to examine gender differences in body esteem and its subcategories, and to find out whether there exists a stronger link between negative body esteem and higher levels of dysfunctional thoughts in women. The relationship between body esteem, dysfunctional thoughts and mental illness was examined. Participants were 73 college students doing social sciences and sports training educations.

As a part of Göteborg Energi?s work towards a smarter electric grid, the company has chosen to investigate the possibilities of automation in their middle voltage grid. In Europe, there are example cases where these technologies already are installed which many articles on the CIRED conference 2011 proved. Netcontrol Oy in Finland has, together with Tekla, created an automated SCADA system that Vattenfall in Finland today uses. The grid mainly consists of 10 kV open loop fed city grid and this automation is mainly designed for this type of grid.

The landscape architect is similar to the moviemaker in that they both want to mediate an experience with their creations. The landscape architect designs playgrounds and the moviemaker makes movies for children, but how does the relationship between children and nature look like in the landscape formed by the movie maker?s fantasy? The purpose with this thesis is to study how the relationship between child and nature is depicted in a movie as a medium, by analysing ?My neighbour Totoro?, a Japanese animated movie from 1988 by Hayao Miyazaki. The analysis consists of two combined analyses, Experiential Landscape Analysis and Gordon Cullen?s Serial Vision, both of which analyse the relationship between a human being and her environment as well as the emotional changes that occur as she moves in it.

The purpose of this study has been to examine and analyze school counselors? experience of collaboration with other professions in the student health team and the preconditions for their work. The study is based on qualitative semi-structured interviews with six elementary-, and two high school student counselors in a medium-sized town in Sweden. The theoretical approach being used is: role theory, theory of professions and theory about collaboration. The study´s result shows that the school counselors? experience an unclarity in their job assignments and their role is often described as diffuse and vauge.

Under de senaste åren har användningen av interna sociala nätverk (ISN) markant ökat. En orsak till detta kan vara den ökade användningen av publika sociala nätverk (så som Facebook eller Twitter) på arbetstid, då detta tenderar att sänka arbetsmoralen och effektiviteten hos de anställda. Ett ISN fungerar i princip som ett socialt medium, men dock innanför ett företags eller organisations interna väggar och fokuserar mer på att främja samarbete, kommunikation och kunskapsutbyte. Detta examensarbete utreder hur man kan implementera ett ISN i en mindre organisation och få det att leva i ett företags vardag. Vanligtvis används ISN inom större företag för att främst hitta och dela kunskap inom organisationen.I denna avhandling kommer jag (baserat på genomförda metoder) skräddarsy ett gränssnitt för Xtractor Interactive AB i ett ISN som heter Totara Social.

The media arena is becoming more and more crowded by various brands and different commercial messages. At the same time, consumers learn how to screen marketing communication and their cognitive ad filters enable them to avoid message elaboration. Thus, new thinking and new communication executions are required in order to surprise the consumers and break through the clutter. In the present study, we have investigated how the choice of media affects attention, memory and several communication effects that the ad can generate in the short as well as in the long term. The study is conducted on a well-known brand within a low-involvement product category.
