Då det ur ett konsumentperspektiv finns ett stort intresse för att kombinera olika miljöperspektiv i en enhetlig märkning samtidigt som forskning visar att en kombination av olika märkningar genererar en ökad betalningsvilja, åsyftar denna studie att undersöka hur dessa två respektive typer av märkningssätt påverkar konsumentens preferenser av varumärket samt hur dessa preferenser skiljer sig åt. Föreliggande studie testar dessutom huruvida Simonsons (1989) teori om kompromisseffekter är applikabel för att öka konsumenters preferenser för ekologiska produkter när ett superekologiskt alternativ tillförs ett valset med ett konventionellt och ett ekologiskt alternativ. Studien bidrar därmed med information till beslutsfattare inom livsmedelsbranschen för hur ekologiska attribut påverkar konsumenters preferenser och betalningsviljan för ekologiska produkter.   408 respondenter har medverkat i en enkätundersökning där svaren har analyserats med hjälp av följande statistiska analyser: reliabilitetstest, t-test, korrelationsanalys, faktoranalys och klusteranalys. Resultaten visar att trots att de flesta konsumenter tenderar att ha såväl en positiv attityd som en ökad betalningsvilja för de ekologiska alternativen, väljer fortfarande majoriteten av konsumenterna det konventionella alternativet, varvid ingen kompromisseffekt uppstår.

The purpose of this thesis was to make an energy survey and quantify energy flows of individual unit operations associated with the biogas production in Uppsala Vatten och Avfall AB:s biogas plant, located at Kungsängens gård. Moreover, large consumers of energy would be identified and analyzed. The objective of this energy survey was to obtain a detailed understanding of the energy use in the biogas production.The energy survey was divided into two parts: electricity and heat. Each part was treated separately and with somewhat different approach. To estimate the electricity usage during the projcet the rated power of each selected unit operation was noted and multplied with thenmeasured time of usage.

Conclusions: A myriad of interpretations are possible when studying and discussing a particular organizational culture. As culture can not be removed from its context, we illuminate the effects that the internationalization process has with regards to unifying the organizational culture in our particular setting studied. Maintaining however, that a reflexive look at this culture shows no single interpretation as being sufficient, we try to expose its richness and ambiguities through a three perspective approach..

Denna uppsats rör sig inom fältet kritiska kulturarvsstudier och fokuserar på svensk utförselreglering av kulturhistoriska föremål genom tiderna. Utgångspunkten ligger i 2014 års omformulering av kulturmiljölagens portalparagraf, vilken numera inkluderar mångfaldsmål. Kulturmiljölagens utförselreglering (reglerad i 5:e kapitlet), som inte uppdaterades samtidigt, är tänkt att läsas mot bakgrund av de inledande bestämmelserna. Eftersom den sedan tidigare uppfattats vila på ålderdomliga nationalistiska värdegrunder, uppstod frågan ifall det fanns en diskrepans i förhållande till de nya målen.För att hitta svar söker sig uppsatsen tillbaka till utförselregleringens formativa moment samt förändring från 1920-talet och framåt och sätter detta i relation till nuvarande kulturpolitiska mål och kulturvård i dagens samhälle. Motiv till utförselreglering men också vilka föremålstyper som skyddats genom tiderna har studerats, analyserats och jämförts kvalitativt.

Mussel meal is a potential source of protein, with a good composition of amino acids, for laying hens and broiler chickens, and may replace the use of fish meal in organic poultry production. Lead and cadmium are heavy metals which occur in the environment and can be accumulated in mussels. When poultry are exposed to heavy metals, the metals are absorbed in the small intestine and distributed in the body in the form of ions, complexes or bound to proteins. In poultry, lead accumulates in bone tissue, liver and kidneys, while cadmium accumulates in liver and kidneys. Generally very low concentrations of these heavy metals occur in muscles of broilers which have been exposed to feed contaminated with cadmium or lead.

The aim of my study is to investigate how last year students in upper secondary schoolunderstand certain mathematical concepts, in particular the unit circle and its trigonometry.I have used intentional analysis to interpret student?s actions when they solve certain tasks onthe basis of a cognitive, situated and cultural context.Interviews with four university teachers in mathematics about the unit circle, trigonometry,and mathematical understanding, serve both as background for the study and as basis for adiscussion, where I relate students understanding to what the teachers want new students toknow about these concepts when they begin university studies in mathematics.The students were arranged in three groups with three students in each group. Each group waspresented with two tasks, one in which they were asked to calculate the cosine values for onepointed, one blunt and one straight angle, each located in a separate triangle. They were alsoasked to decide whether the points (0,71; 0,71) and d (1 2 , 3 2 ) are located on the unit circleor not.My conclusion is that students mainly have an operational conception of the unit circle andtrigonometry. The lack of structural conceptions result in difficulties in seeing connectionsbetween the concepts in unfamiliar situations.

High levels of Hg in fish in Swedish lakes have been a problem along time in Sweden. The major concern is production and accumulation of the most toxic form of mercury; methyl mercury (MeHg). Consequently, in about half of our 83 000 lakes fish contain concentrations above the recommended limit for human consumption of 0,5 mg mercury per kg fresh weight (most of it in the form of MeHg). Consumption of fish containing too high levels of MeHg may cause problems for both humans and animals. Three major sources of MeHg in surface waters are: 1) runoff from terrestrial areas, 2) deposition from the atmosphere, and 3) internal production of MeHg in lakes and streams. The aim of this study was to investigate the effect of clear-cutting on the concentration of Hg and MeHg into draining streams.

Flow measurement is one of the greatest challenges in order to calculate efficiency in hydropower. Most hydropower plants in Sweden use differential pressure methods for flow measurement. These methods are dependent on constant conditions in the waterways. A change in these conditions, like turbine improvements, prevents differential pressure methods to verify efficiency improvements. Since efficiency improvements can?t be verified by one measurement system, another method, which isn?t affected by changing conditions, can be used.

It is a common view that companies should focus on building brands to increase profitability and stabilize cash flows. However, building and keeping brands alive is costly. Many firms spend large sums on branding only because they are supposed to, without knowing if they will actually gain from it. Up to date, there is limited convincing evidence that branding actually contributes to shareholder value creation. This thesis aims to investigate the relationship between brand strength and profitability and shareholder value.

This study aims to examine the views on digitization of eight respondents, all working at different libraryinstitutions in Sweden, and how their views are reflected in their library's digitization strategies. The poll wasconducted on the basis of Ingrid Mason's theory of information standards, their structure and sociopoliticalnature. The informantion standards are divided into three aspects, curatorial, semantic and technical, and theyaffect selection of, intellectual and physical access to the digitized material, which in the end is what constitutes the digital cultural heritage.The background to the study is that the Swedish library institutions in the current situation lacks a nationalstandard or a common strategy for the digitization of cultural heritage, while it is still implemented digitizationprojects at many library institutions. The method used is qualitative, structured interviews with open-ended questions.The study shows that one of the main motives behind the libraries' digitization projects is to make librarymaterials available in a new way, creating greater opportunities for the users to take advantage of the material.The library users are the ones who mainly control what is digitized, although aspects of preservation ismentioned. Furthermore, it appears that the respondents believe that digitization offers improved capabilities tosearch and learn more about the collections, but the actual work of image capture, the addition of metadata,presentation to users and long-term preservation is very complex.Views on what it is to be digitized, how the material should be selected and provided with metadata and howit should be presented to users is what creates the standards that libraries use when they digitize their materials,and digitization of library materials creates new conditions for new users to access and use library material.This is a two years master?s thesis in Archive, Library and Museum studies..

The aim of this Master's thesis is to examine the user discourses that can be identified in the public library field. Questions posed in this study are: what discourses can be found, what characterises them, how are users categorised and what does this categorisation imply. The theoretical starting-point is Ernesto Laclaus and Chantal Mouffes discourse theory. The method is text analytic. 62 articles from three library journals - Biblioteksbladet, Bibliotek i Samhälle and Ikoner are analysed through a model in four phases.

SammanfattningI ett kraftvärmeverk binds en stor del energi i de varma rökgaserna. Genom att installera rökgaskondensering kan energi från röken tillvaratas. På kraftvärmeverket Skogsbacka i Lycksele har man tittat på möjligheterna att installera rökgaskondensering. Detta arbete syftar till att ta reda på om och vid vilka förutsättningar det skulle vara lönsamt för Skogsbacka att också investera i utrustning för elproduktion vid låggradig värme, för att på så sätt använda energin från rökgaskondenseringen. Idag finns flera tillverkare som erbjuder fristående aggregat som kan utvinna el vid låga temperaturer.

The aim of this master's thesis is to study what attitude public libraries in Sweden show towards video games. By using critical discourse analysis as both theory and method we analyse several texts emerging from a debate mainly discussed in blogs. Main topics in the debate are video games in the library, the purpose of the public library and Library 2.0. Our analysis focus on views expressed concerning the work and purpose of the public library, the librarian and the library user - and to identify the main visible discourses in the discussion.Our findings consist of two discourses representing two different views in the debate. We call these two discourses the general educational discourse and the interactive discourse.

Treatment wetlands been showed efficient for reducing pollutant in waste water. In Lajeado ? RS, Brazil the landfill has poor leachate water treatment. It is necessary to supplement the treatment plant because they need to reduce BOD, COD and nitrate of the water going to recipient. A subsurface flow wetland (SSF) can be a good choice.  In order to be able to design an efficient SSF it is important to understand how the grain sizes of a substrate affect the reducing of pollutants in waste water.
