Är det möjligt att använda SCR-rening av rökgaserna vid inblandning av avfall i biobränslet?
Waste appears to be a low-cost fuel compared to biofuel. This Masters thesis was conducted for Vattenfall Utveckling AB and deals with how waste in the fuel affects the performance of a SCR-catalyst. Different mechanisms of deactivation were surveyed, focusing on the poisoning mechanism. A literature study was carried out, which was used as a reference when analysing the results.Small samples (9x2x2 cm, 64 pieces) cut out from a full-scale unused honeycomb catalyst were exposed up to 1500h in two different combustion plants, Johannes in Gävle (co-combustion) and Högdalen in Stockholm (waste-combustion). The activity was measured mainly at 300°C but also at 250, 350, 375 and 400°C.

Analys av diskursanalys i kandidatuppsatser
Purpose: The purpose of this thesis is to examine how students who also serve as writers of bachelor theses mainly utilizing the discourse analysis methodology comprehend the method of discourse analysis, and in what way the students bestow it in their research.Methodology and Material: This is a case study of the theses, which are also the text material, as it can be used examining numerous cases. Another beneficial factor is the relationship to the theoretical framework. One does not need to divorce the two institutions; instead they cooperate with each other.Results: A thoroughgoing apprehension of the Discourse Analysis is it being strongly attached to semiotics and how texts can be analyzed by the method in question to reveal institutions in our society alongside with mapping out the agency of words. In other words, language and soceiety mirror each other in a way or another...Key words: Discourse Analysis, thesis, Foucault, Fairclough, Laclau & Mouffe, language, reality, readings.
Malnutrition i fokus
Patienter som är malnutrierade eller risk för sådan kan vara svåra att identifiera
inom sjukvården, vilket i det postoperativa förloppet kan leda till komplikationer.
Syftet med denna studie var att belysa vilken påverkan malnutrition kan ha på det
postoperativa förloppet efter kirurgiskt ingrepp samt vilket tillvägagångssätt som
används för att identifiera patienter med risk för malnutrition. Metoden var en
litteraturstudie som granskade 10 vetenskapliga artiklar. Artiklarna hittades i
PubMed, MedLine och Science Direkt. Resultatet visar att screeningmetoder som
kan skilja på den underliggande sjukdomen och malnutrition är mer tillförlitliga.
Behandlingen blir mer effektiv eftersom orsaken till malnutritionen identifieras
och kan åtgärdas. Risken för komplikationer ökar ju mer malnutrierade
patienterna är.

Ett intressentperspektiv för hållbarhetsredovisningar : en analys av investerares åsikter och användning av hållbarhetsinformation
This study concerns how Muslims are portrayed in a choice of twelve news articles from Swedish dailies and tabloid newspapers on the aftermath of the film Innocence of Muslims published on YouTube. All articles are distributed in the newspapers Aftonbladet, Expressen, Dagens Nyheter and Svenska Dagbladet in the period of September 11th, 2012 until September 30th, 2012.For this study, a qualitative text analysis has been embraced and focus has been on van Dijk?s Critical discourse analysis to the texts, with additional features from semiotics applied on the images.The theories consist of Critical discourse analysis, hegemony, ideology and power, postcolonialism and stereotyping.In the qualitative content analysis, concrete examples from the articles are retrieved and commented. These have been divided into various themes, which are trends that the authors have been able to distinguish in the analysis.The result shows that Muslims in the analyzed newspapers are portrayed as the others, unimportant and extremely religious, in a negative manner rather than a positive. Moreover the press has tendencies to generalize Muslims as a group.

Effekten av subjektiv riskuppfattning på mental belastning
Människor har en viss mental kapacitet. Beroende på situation och uppgift belastas denna kapacitet olika mycket. Huvudhypotesen i detta examensarbete lyder "en persons mentala belastning ökar om hon/han upplever att risken ökar", oberoende av de krav uppgiften ställer, dvs uppgiftens svårighetsgrad.Undersökningen utfördes som ett experimentet med inomgruppsdesign och 24 försöksdeltagare. Två oberoende variabler med vardera två nivåer användes: Konsekvens, normal/ökad och Information om svårighetsgrad, normal/ökad. Dessa var avsedda att manipulera riskuppfattning.
Trädgårdsterapi inom kriminalvården : en möjlighet för Sverige?

Kartering av markföroreningar inom Skutskärs Bruk samt utvärdering av spridningsrisker enligt Naturvårdsverkets MIFO fas 2
With the prospect of future construction on the Skutskär Pulp Mill property, Stora Enso Fine Paper has initiated an investigation of soil contaminants and a risk assessment of these contaminants. A soil and groundwater investigation has therefore been conducted on an open area of about 16 000 square meters, situated between the current wood room and digester house. To be able to integrate this study into an investigation for the whole industrial property, the study has been carried out as a phase 2 study according to the Swedish Environmental Protection Agency?s Methods of Inventories of Contaminated sites (MIFO).The site investigation has involved soil and groundwater sampling, together with the analysis of heavy metals and organic contaminants. The degree of hazard posed by the contaminants, the level of contamination, the potential for migration of the contaminants, as well as the degree to which protection of human health and the environment is required in the area, have been weighed together for an overall risk assessment of the area with regard to human health and the environment.The investigated area was built up by filling in the coastal waters.
Faktorer som påverkar mobilbanksanvändningen
Many companies today are investing in various computer-based tools to support their planning, decision making or communication processes. However, end users are often reluctant to accept the available information systems, which mean that these investments are extremely risky. Understanding why users choose to accept or reject an information system has proved to be one of the most challenging problems in this research area. Previous studies have focused on users' beliefs and attitudes regarding use intentions, but the results have, however, been both mixed and incomplete. In this study, I have used the Swedish youth? s use intention of mobile banking and a quantitative study was performed based on five different hypotheses derived from previous studies.
