An analysis of a specific application of anaerobic wastewater treatment at a pulp and board mill, Stora Enso Skoghall, was carried out. A literature study was done and effluent wastewater from CTMP pulp production was analyzed. The analysis consisted of a broad constituent analysis and an anaerobic treatment trial. Results from these test where used to calculate the treatment effectiveness and resulting energy potential at the mill.The literature study and constituent analysis showed that toxicity of the water to be treated, due to wood extractives and sulphur content, was of concern. Detoxification chemicals targeting these constituents where used in the anaerobic treatment trial.

The aim of this thesis is to expand the understanding of 16th century Flemish art by approaching paintings by artists Pieter Aertsen (1508-1575), Joachim Beuckelaer (1533-1574) and Pieter Bruegel (c. 1525-1569) from a different perspective. This is done by extending the discourse of art history, into a discourse of literary history and primarily 16th century novels by authors such as François Rabelais and Miguel de Cervantes. The paintings are studied in relation to these 16th century novels, by comparison and as a testament of this specific time period. A widening contextualization is also constructed in which a connection to the expression of the carnivals ambivalent form, as well as the notion of lower classes is explored.

The aim of the essay was to see how the respondents reasoned about different themes like, isolation, integration and barriers to integration, given that they had all been diagnosed with a psychosis diagnosis. The essay takes part of secondary data that had been gathered through interviews by researchers at the department of Research and Development Psychiatric South Stockholm during a 3 year period. To work with the interview data a qualitative interview analysis method was used. The interviews were analyzed against theories of social interaction, labeling, stigma and the theory of ?role exit?.

The forest and mire landscape surrounding the north Swedish villages have been of fundamental importance through time for the farmers. In the Scandinavian summer farm system the forest and mire pasture was used to its full potential. The system consisted of smaller summer farms some kilometres from the main farm in the village, and were the livestock grazed in the forest around the summer farm. The livestock affect their environment, and grazed forests generally contain a higher biodiversity than an ungrazed forest. The overall aim of this thesis is to understand the impact of livestock grazing on a northern forest ecosystem over a long time period.

Detta examensarbete innehåller en beskrivning av växter som under olika förhållanden trivs och kan växa i områden med delvis eller hel skugga. Beskrivningarna av växterna är översiktliga och ämnar inte informera läsaren grundligt om växten utan enbart om enklare fakta för att kunna planera sin trädgård. Jag har valt att inrikta mig på markförhållande beroende på klimatet (torr, fuktig och blöt mark) och markförhållande beroende på substratet (sand, lera, humus och torv) samt temperaturbundna växter. Därefter följer en slutsats där jag reflekterar över mitt arbete. ***********This thesis contains a description of plants that thrive and can grow under different conditions in areas with partial or full shade.

Det har gjorts många studier kring barns språkproduktion medan kunskaperna om hur och när förståelsen utvecklas är mindre. Forskare är eniga om att förståelsen i stort föregår produktionen även om vissa grammatiska strukturer produceras innan barnet har en full förståelse för dem. Att testa språkförståelse är svårt då barnet behöver utföra någon form av handling för att visa vad det förstår. Syftet med denna studie är att jämföra två grammatiska förståelsetest, Nya SIT och TROG-2, dels resultatmässigt och dels innehållsmässigt. Sjuttiosex fyraåriga barn, enspråkiga med svenska som förstaspråk och flerspråkiga, testades med båda testen.

The purpose of this thesis is to examine how acquisition of film for children and young adults in public libraries is carried out. The aim is to investigate why the librarians think a library should have film, if the librarians are bound by acquisition policies and where they retrieve information about films. We also want to know where the films are bought, how the distributors are perceived and how the librarians see their own sphere of competence. The thesis is a qualitative study and is based on interviews with children?s librarians in six public libraries.

The purpose of this Master?s Thesis is to examine and describe how a wiki can be used in the information seeking education. We believe that the preconditions for education and learning are changing; technology and Internet has introduced new tools for the learning situation. To examine this we will describe how the wiki technology can be used in the information seeking education, describe how the goals of the information seeking education are reached when using a wiki and lastly investigate the school librarian?s pedagogical role in wiki-based education.

Organic Light Emitting Displays (OLEDs) are a new type of thin emissive displays predicted to possess superior properties to existing techniques e.g. Liquid Crystal Display (LCD). The main advantages are low power consumption and a thin display structure. This report contains an explanation of the emissive OLED technology, its functionality and the physics of the organic layer structure in an OLED. The technology is described with respect to the two classes of organic materials used in displays, small molecules and conjugated polymers.

In this examination paper I?m using the qualitative method: phenomenographic analysis to present twenty educated and working pre-school teachers opinions about being outdoors in Swedish pre-school. The purpose is to describe the variation between different pre-school teachers? opinions, not to focus on wrong or right.    The paper starts with a review over the opinions presented by the literature on the subject.

The purpose of this paper is to present a possible understanding of why the company Tekola is segregated according to sex. In accordance to this purpose, an understanding of how the segregation affects the employees in relation to power, values and possibilities is discussed. The theoretical understanding is that the organization of men and women within Tekola is done in close connection to creation of the meaning of gender in Tekola. This, in turn, affects and is affected by the recruitment to and within the company. Through the study of statistics from a survey, five interviews with employees and former employees and Tekolas? equality plan, we are able to see the possible existence of a glass ceiling, and a culture of homosociality, which affects the possibilities of women to enter the company and also to gain full entrance to power-positions in a negative way.

The aim of this Master?s thesis was to find out more about the delimiting quality- and shelf-life parameters over time for liquid oat-based products. According to that, to present applicable subjective and objective shelf-life test approaches at accelerated conditions. The study aimed to gain a deeper knowledge concerning the general and accepted way of performing accelerated storage tests. This study focused especially on products, which suffer from quality failure caused by oxidation, such as liquid oat-based products.

Positive action is measures that usually constitute discrimination but which are justified when achieving the purpose of an effective equality between people of the society. Positive action regarding gender is regulated in primary law, secondary law and case law of the EU whereas positive action regarding other discrimination groups is regulated in secondary law and negligible regulated in case law.There is a boundary between positive action and discrimination. Primary law gives little guidance on determine that boundary. Secondary law provides more advanced guidelines of how to determining were the boundary is.When determining were the boundaries lays between positive action and discrimination the guidelines given by the European court of justice in case law can be used. The majority of these guidelines are focused on positive action regarding gender.

Grundtanken med fysik är att den ska användas för att förklara omvärlden. Vi upplever att det i skolans fysikundervisning ofta läggs större vikt vid att tillämpa formler än vid att förstå själva fysiken. I den här undersökningen fokuseras därför elevers förståelse för fysikaliska fenomen de möter i sin direkta vardag.En klass gymnasietvåor på det naturvetenskapliga programmet fick skriftligt förklara fem fysikaliska vardagsfenomen, där teorin behandlats i Fysik A. Svaren kategoriserades och kategorierna ordnades därefter hierarkiskt efter hur väl de överensstämde med den vetenskapliga förklaringen. Eleverna behövde inte använda vetenskapliga begrepp utan resonemanget var avgörande för kategoriseringen.Utifrån resultaten drogs slutsatsen att de allra flesta eleverna gav ett svar inom rätt teoriavsnitt medan endast ett fåtal elever visade på full förståelse.

Citizen participation is fundamental in place analysis, where the aim is to define the sites specific character and identity. The local citizens know the village better than anyone else since they lead their daily life in the environment. I have in cooperation with Sala municipality suggested guidelines on how to involve the local people in dialogue during place analysis. The target was to involve and enthuse as many people as possible with relatively small resources in time and money. The suggested methodology was tried out in a place analysis of Västerfärnebo, a community with about 3 000 inhabitants of which 500 live in the main village.
