Abstract.The levels of dioxin and comparable substances rose to a large extent in our environment during the second half of the 20'Th century. This was the result of the synthesis of, and careless usage of these substances in cooling fluids, hydraulics, pesticides etc. Background levels of dioxins and furans in sealed samples prior to this era suggest that former sources of these substances existed. Salt glazing is a method of adding a smooth acid resistant exterior to stoneware ceramics. The technique has been in use since the 16'Th century, maybe even earlier than that.

The increased use of social media in recent years has attracted the attention of different kinds of nonprofit organisations. The purpose of this study is to identify a foundation for viral strategies for nonprofit organisations as well as to understand the current interactivity between the organisation and its followers in social media. Following that we have chosen the research question: In what ways can nonprofit organisations develop viral marketing in social media? The study has a qualitative research methodology with empirical findings as base. We have throughout the research process strived for an inductive nature in the study though there are deductive elements.

Syftet med högskoleavhandlingen var att konstruera en klass-D förstärkare för audio med en DDXi-2161 krets från Apogee. Förstärkaren har en digital stereoingång för I²S-format. Digitalisering av en analog audiosignal sker med codec-kretsen WM8731 från Wolfson. För att möjliggöra implementering av funktioner för digital signalbehandling av audiosignalen ingår en FPGA-krets från Altera i systemet. Gränssnitten mellan codec-kretsen och FPGA:n samt FPGA:n och klass-D förstärkaren är beskrivna med VHDL och implementerade i FPGA:n.

Vid sändning av digital television är det möjligt att utöver ljud och bild även sända och erbjuda olika typer av tjänster och applikationer till mottagare. Vid utveckling av applikationer för digital television kan man välja att utveckla i antingen DVB-J (som är en bantad variant av Java för exekvering i Set-Top-Boxar) eller i DVB-HTML (som till stor del överensstämmer med XHTML). Syftet med detta arbete är att utreda hur DVB-J och DVB-HTML kan kombineras i en och samma applikation och hur interoperabilitet kan uppnås mellan DVB-J och DVB-HTML..

The traditional Swedish way of dealing with browsing damages made by moose, is to reduce the moose population. However, a growing way of dealing with damages made by several ungulate species, including wild boars in particular is to redistribute them with supplementary food sources. Attracting them to settle in habitats less vulnerable to damages made during foraging. This study we tracked collared moose in southern Sweden from January throughout April in the year of 2009. From the tracking data their ?favourite? positions was selected and visited in order to study the features that attracts moose during winter.

I denna kvalitativa studie undersöks hur ungdomar i 19-25 årsåldern ser på hälsa och hälsokommunikation. De är så kallade ?digitala infödingar? dvs. ungdomar som är uppväxta med och använder sig av digital teknik. Tio ungdomar har intervjuats med syftet att få ett underlag som kan öka förståelsen för digitala infödingars beteende och behov när det gäller hälsa.

The aim of the study is to learn more about the way preschool teachers work with Information and Communication Technology(ICT). More specifically, this study aims to explore how preschool teachers describe their experience of ICT, the conditions and opportunities to work with ICT, and their own knowledge and competence in the use of digital tools with preschool children. The research method consists of interviews with preschool teachers and observations at five municipal preschools in Stockholm as well as an analysis of the relevant passages in the Curriculum for the Preschool and the Curriculum of Stockholm city. This study shows that there seems to be great variation in the amount of ICT tools present in preschools. Preschool teachers expect a lot from ICT, and the improvements that it can make on their work.

This report is about helping Q-Med AB in Uppsala to start its implementation of uncertainty of measurements analyses in their manufacturing department. Prior to this, the company relied solely on personal experience or did not take this uncertainty into consideration at all during different kind of measurements, which means that some of the processes that the company previously believed were within specified acceptance limits, will actually fail when considering these sources of uncertainties.Q-Med AB needed some sort of instruction to help the company, in a systematic way, to investigate different types of disorders that are affecting all kinds of measurements. This instruction includes a short summary about measurements and uncertainty of measurements in general and a detailed procedure about how these uncertainties are going to be handled in their daily work.The goal was to be able to use this instruction to systematically locate, eliminate (when possible) and analyze all kinds of disorders when measuring. Q-Med is using a lot of different types of instruments when measuring different types of quantities, including temperature, mass, pressure and density. This instruction will hereafter be used for every instrument, regardless of quantity and type of instrument.The instruction is tested through 4 different kinds of measurements, for mass, temperature and humidity.

This masters thesis aims to investigate how upper secondary school pupils experience their information seeking in a school context without access to a school library. It is the pupils own thoughts and opinions about information seeking and criticism of the sources that is the main focus. The literature that has been used consists of material from research concerning youth and different aspects of information seeking such as the information seeking process, information seeking on the web, criticism of the sources and how pupils interact with other people in order to acquire information. The method that has been used is group interviews. Twelve pupils from an independent school without access to a school library have been interviewed in groups of three.

This paper examines how and if the understanding of wedding photography has changed during the shift of technology - from analog to digital photography. It examines if the changed conditions due to the shift of technology have changed the habits and conditions for the photographers working with wedding photography. It furthermore examines what impact these habits and conditions have had on the pictures of weddings. The investigation is based on interviews of six photographers that have worked professionally before and after the shift of technology, as well as of pictures by the photographers taken before and after the shift of technology.Use of time and space has changed due to the shift of technology. The change has also had an influence on hierarchy among the photographers.

The purpose of this paper was to investigate the foremost teachers thinking of computers in teaching, how they work practically with computers as a tool, and if it is reflected in the students' school performance. To carry out this study, I used qualitative interviews as a method and I have interviewed four teachers where two works at the high school and two in upper secondary school. Both schools use computers in teaching as a supplementary tool for teaching materials. All teachers have similar ideas regarding what purpose one should use the computer and in which way, but the important thing is that the teachers and students receive an introductory course in how to use computers. Educators agree that this approach is and can promote students' language and knowledge regardless of the subject.My informants have come up with own methods that they use in the digital classroom including Skype, YouTube, Facebook and flippedclassroom where one can learn from other educators working.

The purpose of this thesis is to discuss the possibilities of, and interest in, a digital download service at the music departments of the libraries. I chose to conduct my study at the city library of Gothenburg. I studied the legal download services that exist today and I did a statistical survey among the users of the music department, followed up by interviews to see how they took to the idea. From the inquiry I learned that a majority of the users was negative to having a digital service replacing the physical department, although a majority was positive to try a digital service. I also used the inquiry to compare the reasons for downloading music to the reasons for borrowing records from the library, but there was no significant difference.
