When a combined heat and power plant produces heat and power it often faces a deficit of heat load during the summer or other periods of time. This heat is often unnecessarily cooled away or the power production has to be reduced or shut off. If it is possible to store heat from periods with low heat demand to periods with high heat demand one can get many benefits. Among these benefits are: increased power production, decreased operation with partial load, uniformly distributed load.To be able to store heat in situations like this long-term thermal heat storages are needed. In this thesis five different types of stores are presented: rock cavern storage, tank storage, pit water storage, borehole storage and aquifer storage.

?-galaktosidas assay för studie av promotorregion i kloritdismutas från Ideonella dechloratans
Oxochlorates are anions with a partially naturally occurrence in nature but are also spread by human activities, including the paper industry. These compounds are harmful to both nature and humans, which makes it necessary to find a good way for their degradation. There are two different kinds of bacteria that can use oxochlorates as electron acceptors in their metabolism, bacteria that break down perchlorate and bacteria that break down both perchlorate and chlorate. A bacterium that can break down chlorate under anaerobic conditions is Ideonella dechloratans which holds the genes for chlorite dismutase and chlorate reductase which are enzymes for the degradation of chlorate. Gene expression and enzyme activity of chlorite dismutase are induced under anaerobic conditions, which makes it interesting to find out how this regulation functions in order to better exploit these bacteria in biological wastewater treatment.
När en roman blir teveserie: Om Jane Austens aktualisering i och med 1995 års teveinspelning av Pride and Prejudice
The aim of this Masters thesis is to examine how Jane Austens Pride and Prejudice, first published in 1813, was established in different literary orbits after the transformation to the television medium in 1995. I also want to find out what this adaptation meant for the popularity of Jane Austen, the circulation of her works and the rebirth of her authorship. It has furthermore been of interest to discuss the reasons why Jane Austen and her works became so popular. Questions posed in the study are: What has the 1995 production of Pride and Prejudice meant for the spreading of Jane Austens literary work and for the rebirth of her authorship? How has Pride and Prejudice moved between the literary orbits after it became a television-serial in 1995? Why did the circulation get the character it got in the 1990s? In order to find feasible answers to these questions I have used Hans Hertels model of the five literary orbits as theoretical starting point.
Tv-spel som kultur? : En kvantitativ studie över tv-spelens kulturella plats på folkbiblioteket.
This study examines the cultural place and status of video and computer games in the Swedish public library. Using works on popular culture and the theories of Pierre Bourdieu, this study employs quantitative methods, as well as textual analysis, to analyze the results of an online questionnaire with 19 questions focusing on selection criteria, shelf placement, perceived competence, as well as reasoning for having or not having these games in the library. 286 out of the 440 libraries contacted is participating in the study, and the libraries consist exclusively of public libraries in Sweden that are found in the database of the Royal Library.The results of this study show that a larger number of libraries than previously indicated have started to provide electronic games to their patrons. At the same time, patterns in the data and comments suggests that these games in many cases still do not enjoy the same level of cultural recognition as other media. Indicative of this is the way most libraries seem to focus on the medium being exclusively for their young patrons, with seem-ingly very little in the way of investment for adults.
Bioactive peptides in long-time ripened open texture semi-hard cheese
Bovine milk is an excellent source of bioactive peptides. The bioactive peptides are in an inactive state in the protein and are released during enzymatic activity, e.g. during cheese ripening. Specific properties of bioactive peptides from ripened cheese has been reported, e.g. antihypertensive, antioxidative, antimicrobial, immunomodulatory and mineral binding.
Utomhuspedagogik : En studie om förskollärarnas förhållning till och arbete med utomhuspedagogik
Abstract The purpose of this paper is to investigate teachers´attitudes to and work with outdoor education in preschool. The aim is also to identify the opportunities and barriers that exist to conduct outdoor education. In my research I have interviewed six preschool teachers in a medium sized municipality, where five of the teachers worked in the suburbs to the Big City and one teacher worked in the downtown Big City. All respondents in the study were in favor of conducting outdoor education. The respondents claimed that it promoted children´s health and motor skills. The result also shows that the teachers saw a great opportunity for learning related to outdoor education, by using the resources of nature.
En dekonstruktion i ljud : J.O. Mallanders Extended Play
J.O. Mallander?s Extended Play (1968) is a sound recording, a readymade, of the counting of votes in two presidential elections in Finland, during 1962 and 1968. A voice repeats monotonously: ?Kekkonen, Kekkonen, Kekkonen, Kekkonen, Kekkonen?? Although the Finnish president Urho Kekkonen represents, almost personifies, the politics of the post World War II period in Finland, Extended Play does not explicitly address the political. Rather, as this essay argues, it engages in the discourses of power and politics by providing a temporalization of its fixedness, or what Jacques Derrida terms the proper.Extended Play is, in parallel with Derrida?s critique of western metaphysics, a deconstruction in sound that challenges the state ideologies conveyed in the process of the counting of votes, where the presuppositions of the presence of the voice characterizes the ambiguities of power that Kekkonen?s politics of neutrality represent.Mallander?s readymade emerges as a double of the game theory strategies of the Cold War, a mimetic surplus of the administrative control mechanisms of sound recording.

Göra, veta och känna : - En fokusgruppstudie i attityder till produktplacering i olika medier
Produktplacering har växt i popularitet över åren och används i allt fler typer av medier. Det har gjorts flera studier om konsumenters attityder till produktplacering men endast ett fåtal av dem har gjort en distinktion mellan konsumenters attityder till produktplacering i olika slags medier. Genom att använda fokusgrupper ska denna studie därmed undersöka studenters attityder till produktplacering i de fyra följande medierna; filmer, musikvideor, datorspel samt bloggar. För att ta reda på detta användes ABC-modellen av attityder och studenternas attityder delades upp under de tre olika kategorierna inverkan, beteende och kognition. Resultaten visar att studenter överlag är positiva till produktplacering i filmer och anser att det ofta är en naturlig del av filmer.
