In conventional viscose manufacturing, a large amount of carbondisulfide is consumed. This amount has to be decreased to keep the production cost down and to reduce the environmental impact. The purpose with this work was to show if an enzyme treatment of a dissolving pulp could increase the degree of substitution in the viscose so that the amount of carbon disulfide consumed in the process could be decreased. Previous investigations by Kvarnlöf (2007), Engström et.al. (2006) and Henriksson et.al.

Abstrakt Produkten som jag har utvecklat är en mjukvarubaserad 3D-renderare. För att göra en sådan produkt är man tvungen att gå djupt in i området 3D och utföra alla beräkningar på egen hand. Dessa tar annars grafikkortet hand om. Denna rapport förklarar varför jag har valt att göra en egen mjukvarubaserad 3D- renderare och vad den är för något och i vilka områden den används. Här förklaras även min syn på programmering, digitala spel, vad programmering innebär för mig och hur min syn på spel har påverkat mig med tiden.

The purpose of this study was to evaluate enantioselective analytical methods by separation of the enantiomers of four drugs (citalopram, zopiclone, tramadol and methylphenidate) and their metabolites. The analyses were performed with HPLC-UV with columns whose stationary phases were based on macrocyclic glycopeptides (Chirobiotic V, V2 and T) and polysaccharides (Lux Cellulose-1, Cellulose-2 and Amylose-2).The Chirobiotic V column showed high selectivity for citalopram and its metabolites. High resolution was obtained using a mobile phase consisting of methanol, acetic acid and ammonia. High selectivity for the enantiomers of zopiclone and its metabolites were obtained on the Cellulose-2 column using a mobile phase consisting of acetonitrile and ammonium acetate buffer.The enantiomers of tramadol were separated with the Amylose-2 column. However, changes in the pressure arose, probably caused by the additive NH4HCO3.

The aim of this study was to investigate how the position of the preschool teacher could come across in interviews with six teachers about their assignment to document and evaluate the preschool activity. The research done so far in this area shows that it can be a complex and difficult part of the preschool teachers work. A dilemma often described is how the teachers can be able to analyze and document the children´s learning with the aim to evaluate and develop the preschool activity without judging and mapping the children. A special focus of the study was to see how the methods and dsicourses described by the teachers possibly could affect the teachers´s position in the area of documentation and evaluation. To analyze the empirical data Ernesto Laclau (1935-2014) & Chantal Mouffe´s discourse theory was used, a prespective witch also figured to be the theoretical foundation of the master thesis.

Här förklaras även min syn på programmering, digitala spel, vad programmering innebär för mig och hur min syn på spel har påverkat mig med tiden. Jag tar även upp mina tankar om spelindustrin och samhällets misstolkade värderingar av spel samt vad för sorts spel jag anser skulle gynna mänskligheten i framtiden. Vad jag tycker om utbildningen Digitala spel nämns också samt hur jag tror att den skulle kunna förbättras. Slutligen följer en kortfattad beskrivning av hur mitt projekt har genomförts. Abstract The product I have been developing is a software based 3D renderer.

The aim of this study is to illuminate images and discourses, in which media describe people with disabilities. The purpose of the study will be fulfilled, by answering the following questions: Is it possible to discern categories of how people with disabilities are described in the media and is it possible to find associations to handicap models? We have chosen to focus on how media describe people with physical impairments and have made a content analyses of articles, based on the theoretic aim of this study, social constructionism, handicap models and earlier research. Underlying the analyses, are six articles from two Swedish news papers. The results of our research are divided in three categories: assumptions which are taken for granted, hidden meanings and contradicted categories.

In this essay I want to investigate how the poodle strategy affects a person?s credibility when he or she uses it. The poodle strategy is a strategy, which someone uses when he or she is scrutinized by the media. It?s primary purpose is to suppress further media coverage but it is also a strategy for defending oneself and hence rescuing one?s reputation either as a private person or as an official.The essay?s research questions are:How has the strategy been applied for defensive purposes and what are the results?To which extent can the Stasis theory and Benoit?s theory on Apologia be connected to the strategy?Does the strategy affect the user?s credibility?To answer these questions four cases from the political sphere in Sweden where persons have been said to have ?done a poodle? have been analyzed.

The subject of this thesis is the history of the library at The Göteborg Museum of Art. The aim of the thesis is to depict and analyze the emergence and the expansion of the library?s holdings until 1939. To fulfill the aim, two questions are asked. The first question is: Is it possible to argue that the library?s holdings were collected to document the entire world of art? The question is formulated in relation to a comment by Susan Wyngaard.

This paper constitutes graduate work at the Depart-ment of Urban and Rural Development at the Swedish University of Agricultural Sciences. In this paper the urban structure of the million program suburb Husby in Stockholm is examined and what effect this structure has on social life in the area. The main objective of the study has been to, with the help of morphological analyses, examine how to create meeting places and make the Husby Park more accessiblefor the inhabitants in Husby. There has been a selection of analyses to ensure that Husby?s spatial relationship with surrounding suburbs as well as local spaces in the Husby Park is described.

As a result of an increased consumption, waste volumes has grown steadily throughout the 1900s, and this puts great demands on an efficient and ecological sustainable waste management on both local and national level. In order to evaluate collection and disposal of household waste, a large number of Sweden´s municipalities are using waste analyses. The overall aim of this study has been to summarize and assess results from waste analyses executed in Härjedalen´s municipality during the years 2007-2011.The evaluation has given information about the household waste´s composition, quantity and change in time. The report´s objective has been to create a basis which the municipality can use in planning of future information efforts and other measures, and give some proposals on how these can be designed and targeted. Therefore, the report also highlights research on motivations factors that affects environmentally conscious behavior such as recycling, and how different instruments like information can be used to promote this.

The overall aim of this thesis is to examine how Easy-to-Read information, used by governmental agencies, facilitates and limits the field of possibilities for the intended recipient, based on the information.This, in anera of e-government.The theoretical framework is based on two Foucauldian concepts governmentality and discourse analysis. Representatives from five Swedish governmental agencies have been interviewed and the results have been analyzed based on the following questions: (1) How do the representatives construct the category Easy-to-Read? (2) How do these representatives construct the recipients of Easy-to-Read? In order to broaden the understanding of Easy-to-Read, an important national level policy document, containing a summary of strategies and goals for e-government has also been analyzed based on the following questions: (3) How is the e-government constructed in the text? (4) How is the citizen constructed and positioned in the text? The collected material is analyzed using a discourse analysis inspired by Foucault.With the results from the interviews and the analyzis of the policy document, Easy-to-Read information has been discussed and examined as a technology to meet the needs of people with reading difficulties, putin an era of e-government.The findings of the study include the following: (1) The e-government is constructed as a service agency and the citizens are positioned as clients. Furthermore, the citizens are expected to participate digitally and be digitally competent. (2)Some of the representatives does not know, with certainty, to whom the texts are directed or if they are used.

In Sweden, there an increasing need for transport and this leads directly to fuel demand of the transport sector is expected to increase. Both politicians and industry believes that renewable fuels are a realistic and significant method to reduce the transport sector's environmental impact. This study aims to document the Swedish haulage contractor?s attitude to biodiesel. Also to document the strengths and weaknesses of biodiesel, based on opinions from the ultimate consumers.

The following project has been made in collaboration with, Denator AB, a biotechnology enterprise. One-dimensional electrophoreses have been used to analyze protein contents of tissue samples. Tissue samples have been either treated according to the company´s newly developed tissue treatment technique or not treated at all and comparisons between these samples have been made. In order to see differences in protein patterns between samples more clearly, a conversion method has been developed where electrophoresis gel visual patterns are used to produce curves, similar to densitometer curves.Denator AB would like to know if the proteins in their treated samples will change visibly over 48 h when incubated at room temperature. This has been investigated using the above mentioned method.

The purpose of this paper is to examine how the relationship between the socially constructed genders is manifested in American library science. To visualize gender, bibliometric analyses of peer reviewed articles published in three core journals of library science between 1980 and 2000 inclusive, are performed. The three journals are: College and Research Libraries, Journal of Academic Librarianship and Library Quarterly. Questions: 1. Does gender affect the publishing process regarding the distribution of female and male authors? 2.

Comfort analyses regarding human induced vibrationsIt is not too common among civil engineers in Sweden to perform comfort analyses considering the vibrations caused by human activities. In addition, the Swedish standards lack requirements to be used for comfort analyses in design of floor-systems. The demand for large spans in combination with slender slabs, is today a reason to investigate the floor-system constructions, in order to prevent disturbing vibrations and oscillations.The purpose of this thesis is to create a guide for how a comfort analysis, considering vibrations, should be implemented. Göran Svedenbjörk who is an expert in structural dynamics has been interviewed where he presents his latest project Värtaterminalen and answers some questions about vibrations due to human activities.Floor-systems, consisting of concrete slabs supported by steel or concrete beams, have been investigated with simulations in the finite element program Abaqus. In the simulations, the influence of various factors on the natural frequency of floor-systems and the acceleration level caused by dynamic loads, is studied.
