Perfluorinated substances (PF) are environmental pollutants that are used to coat fibres of so called ?all weather clothes? to make them water resistant. PF are effectively spread through water. Waste water treatment plants (WWTPs) are a pollutant source of these substances. PF are poisonous to different kinds of organisms, and supposedly also to human beings, if concentrations are sufficiently high.Perfluorinated substances have been investigated at three waste water treatment plants in Stockholm during the 2000?s.

The purpose of this essay is to examine if there is any difference in the style of conversation between a municipal politician and a politician in parliament? In order to answer this question I have created two sub-questions that are more precise. The first question is: Are the municipal politicians more open to cooperate with politicians from other parties than the politicians from parliament? And the second question is: Is the rhetoric between the politicians in parliament different than the rhetoric between the municipal politicians?My study is a comparative case study with two different groups of politicians. With the help of a survey I have tried to examine if there are differences in the use of language in the daily work for the politicians.

reMIND är ett verktyg som kan användas för att modellera och optimera processer. Programmet genererar ett ekvationssystem som därefter kan optimeras av ett externt optimeringsprogram. Ursprungligen utvecklades reMIND på Linköpings universitet och är ett ?Open Source?-projekt. Programmet befinner sig fortfarande på utvecklingsstadiet och målet med det här projektet är att komma vidare i den utvecklingen.

The project deals with the evaluation and testing of speaker and microphone elements as well as microphone cavity.The first part of the report comprises a comprehensive theoretical part about drivers, microphone elements, and to some extent microphone cavity.The goal was to , on the behalf of the company Limes Audio AB, develop proposals on microphone element and cavity as well as drivers for a speakerphone application, based on specific factors. The main factors were performance, price and form factor.The aim was to create the best possible conditions for Limes Audio's software developers to implement the company's audio-enhancing software, mainly adaptive echo cancellation.The testing was carried out using Adobe Audition and MatLab. The test methods were developed in conjunction with Limes Audio and are described below.The project will result in suggestions for a speaker, a microphone and a cavity. The cavity were removed from the product because the results indicated that the cavity matter little for the end result.The report concludes with a discussion on how the measurements could have been enhanced to simplify the interpretation of the results and making the testing more efficient..

Eutrophication of lakes and streams are nowadays a well known environmental problem and implies an enrichment of the nutrients phosphorus (P) and nitrogen (N). Phosphorus is considered to be the most important component for the growth of aquatic plants and leads in too large quantities to an intensification of growth. Phosphate (PO4) is the fraction of phosphorus that can easiest be taken up by plants and thus have the greatest impact on eutrophication. Increased plant growth in lakes and unfavorable conditions for aquatic animals are two examples of negative consequences. A significant portion of the increased nutrient supply to nearby water can be derived to phosphate leaching from agricultural areas, where private sewers and agriculture is two main sources.

There are several methods and models within the areas of software engineering on how to proceed during a software development process. For each of these methods and models there are benefits and drawbacks, depending on how you choose to look at them. A difference of principle between the different models is that they either advocate iterative development or not. In parts of software engineering one makes use of different methods depending on which is most fitting in a specific situation. There are several methods on how to recieve more qualitative data from the end-users during the requirement collection, but the reappearing pattern is still user centric participation, which means that the user participates more actively in part of or the entire development process.

The web has evolved much through the years. From being a place where author and reader were clearly distinguished, it now invites everyone to take part in the development of both content and technology. Social services are central in what is called Web 2.0. Wikis, blogs and folksonomies are all examples of how the users and their communities are key to the development of services. Collaborative writing, tags and API:s are central.

Bakgrund: I och med den tilltagande teknologiska utvecklingen och globaliseringen ställs dagens företag ständigt inför nya utmaningar. För att handskas med detta måste företag arbeta för att skapa innovationer på ett sätt som de inte gjort tidigare. Det handlar om att släppa sargen ochvåga göra saker påett nytt sätt! Ett sätt för dematt göra detta är att tillämpa synsättet som kallas ?Open Innovation?, alltså att man tar hjälp av intressenter utanför företaget för att bli mer innovativa. Crowdsourcing är en del av open innovation ochinnebär bland annat attföretagtar hjälp av ?folkmassan?för att skapa nya idéereller lösa problem.

This essay examines the way the recurring motifs in Karin Boye's poetry might be read as expressions of queer or subversive desire. The fact that the lyrical I is not gendered in the poems opens up for a queer reading. In adherence to Sara Ahmed's notion of desire lines and sexual orientation I discuss the spatial aspects of desire, and explore the positions and movements of the lyrical I in Boye's poetic landscape as deviations from the concept of the straight and marked path, into the queer and unknown.I trace desire in Boye's poetry mainly through the themes of nature and night, and the ways in which these phenomena deviate from the normative structures laid out by the poems. Usually the motifs of night (such as fog, shadows and darkness) are associated with the fading of the senses. The night obscures the vision of the lyrical I and wraps them in heavy silence, making them experience and desire in new ways. Through motifs related to nature Boye formulates a feminine, matriarchal myth.

The main purpose of this Masters thesis was to examine how the Internet and other electronic sources have affected public librarians use of printed reference sources. During the last couple of years the use of the electronic sources - in particular the Internet has become more established in the Swedish public libraries. Our aim was to examine if and how this has affected the use of the printed reference sources. This has been examined on the basis of the following factors: the gender and age of the librarians and how long they have served in the library. We also examined if the size of the library affects the use of the printed and the electronic reference sources and also which factors that are most important when librarians acquire reference sources.

LKAB is an international high tech mineral corporation and a world leading manufacturer of refined ironore products for steal manufacturing and other mineral products destined other industries. LKAB is an international corporation with companies world wide, with it?s main location in the north of Sweden, which is where the iron ore mines and the refining works are located. LKAB?s iron refining process in Vitåfors, Malmberget, is a source of great amounts of waste-rock.

This is a study about the relation between the Swedish school and the political system of Sweden. I wanted to see if the relation had changed since the election of 2010 as it was in that election the Sweden Democrats got over five percent of the votes and took seat in the Swedish parliament. The thing that is unique about this election is that it was really the first time a right-wing party had been elected into the Swedish parliament. Many experts argue that this is the first xenophobic party that has been elected into the Swedish parliament. This led to a problem for schools and their principals and a difficult question to answer because xenophobia is contrary to the school?s core values and the school?s democratic mission.Should the school still be open for political parties? How do schools manage to distinguish between political information and political propaganda? If parties still are welcome into the schools, which parties should be allowed? The equality ombudsman has said in a report that the schools have to comply with the principle of objectivity, which stipulates that the public sector has to be unbiased.I have chosen to make use of a qualitative method because I think the study then gets a deeper understanding of the topic.

I denna rapport undersöks hur elektroniska böcker (eBooks) enligt standarden Open eBook Publication Structure kan komprimeras på ett effektivt sätt. Anledningen till att området valts är att en välanvänd standard för eBooks inte finns för tillfället. Standarden är relativt ny och senaste versionen av specifikationen har kommit ut under 2002. Med i utvecklingen av standarden finns många stora företag som exempelvis Adobe Systems Inc. och Palm Digital Media.

At Flight and Systems test Saab AB, a post-processing software is used to process GPS data. A new software by the name GrafNav has been purchased and the purpose of this master thesis therefore became, partly to make a judgment regarding GrafNav?s ability to estimate position, velocity and accuracy, partly to if needed improve the estimate and finally find one or several methods to estimate the position and velocity accuracy. The judgment of GrafNav was performed partly by a comparison to the former post-processing software (PNAV) and partly by a comparison to the airplane?s inertial navigation system (INS).
