The sun is an endless energy source and the heat it produces can be used to heatup our homes. This technology is relatively old and was introduced in the late70-s. There are two kinds of solar collectors that are most frequently used todayand these are plain solar collectors and vacuum solar collectors. The plain solarcollectors are the once that are used the most but the vacuum solar collectorshave increased more as a percentage the last couple of years.The biggest question asked regarding an investment in solar heating is if theplant is economically profitable. This question has no direct answer because itis dependent on a couple of prerequisites.

The purpose of this thesis is to investigate the status of Swedish real estate companies in terms of financial health and risk of financial distress. The background is the ongoing financial crisis, which partly can be derived from the American real estate sector. Publicly available accounting information from 16 listed real estate companies has been analyzed for a period of one year using financial ratios covering both the operational and financial activities. We find that the deceleration in the economy and in the real estate sector have forced the real estate companies to make large write downs, in line with the relatively new accounting rules, IFRS. Write downs are likely to reoccur during the following periods and real estate companies will therefore probably be forced to continue to show negative results.

In this paper we examine how young women present themselves on their weblogs. The main purpose of this study is to get their own opinions and thoughts about their own blogging, to see if we can find norms for how they present themselves and how the presentation online matches themselves offline. We put this in relation to information technologies, social software and Computer mediated communication, CMC. It´s also in our interest to see how the phenomenon of blogs, its role and methods of communication have changed and developed in the last few years, and whether there are differences in the way people use it according to age. The major finding is that, unlike previous research, the women in our study tend to be themselves in their weblogs and they do not manipulate their identities.

The aim of this Master's thesis is to understand public library users' perceptions of librarians' attitudes to users and professional knowledge. The purpose was also to investigate the relative importance to the user of pleasant or a knowledgeable librarian. As a theoretical framework we use theory from business economy where the experience of the user is in focus. Answers were sought to the following questions: How do users perceive librarians attitudes to users? How do users perceive librarians professional knowledge? How do users want to be treated by public librarians? What kind of knowledge should public librarians have, according to users? We interviewed twelve students in university education that are users of public libraries.

Purpose/Aim: This essay explores the framing and representation of pensioners in Swedish press during the period of 2002-2008. The aim was to investigate what meaning news give elderly people on the manifest level, and also what meaning the media texts construct on the latent level.Material/Method: For this paper I have investigated framing of pensioners using quantitative analysis of 100 news articles, followed by a qualitative hermeneutic analysis applied on the most frequent frames discovered in the quantitative study.Main results: Four frames were identified concerning pensioners: crime victims, heroes in daily dues, economically advantaged and economically disadvantaged. The dualistic result in the economy frame was investigated in the qualitative research. The study revealed that pensioners as a group may have good economic standards, although there are individual differences. Three stereotypes were discovered in the articles: ?kind granny?, ?fragile and miserable? and ?look what I can do?..

In this project a simulator has been developed (in C++) with the purpose of illustrating how changes in environmental regulations, tax levels and other policy measures affect the composition of an energy system. The aim of the project was to investigate how energy companies? investment strategies are affected when changes in economic and environmental conditions occur. A standard scenario has been created based on current Swedish conditions, but the user can create new scenarios and set parameters freely. The user is tasked with building power plants to supply the city/region with district heating and electricity during a pre-set number of years. When the simulation is finished the result is graded in the following categories: economy, environment and quality. To evaluate the simulator three scenarios were created (?early 20th century?, ?reduced environmental control? and ?future?) in addition to the standard scenario and these were compared with each other by examining how a select group of power plants perform under the given conditions.

Detta arbete går ut på att jag, i ett antal improvisationer, undersöker möjligheten att spela utan att tänka på, reflektera över eller värdera det jag spelar. De frågor och funderingar jag kommer att utgå ifrån är: * Kan jag spela utan att reflektera över detta jag spelar?* Kan jag spela utan att värdera det jag spelar? * Hur påverkar dessa försök och förhållningssätt mitt musicerande i olika spelsituationer? Dessa frågor försöker jag besvara genom att med olika ramar och utgångspunkter göra undersökningar genom att improvisera och samtidigt dokumentera detta. Efter varje improvisation noterar jag hur jag upplevde situationen och jämför sedan detta med hur det lät och såg ut. Jag kommer att knyta an detta till Kenny Werners bok ?Effortless Mastery? och Stephen Nachmanovitchs bok ?Free play?..
