Barns minnesåtergivning - uppkomsten av falska minnen och suggestionspåverkan utifrån positiv respektive negativ information
Falska minnen förklaras teoretiskt med bl.a. implicita associationer, och svårigheter att skilja mellan faktiska eller påstådda källor. I denna studie undersöktes huruvida positivt respektive negativt innehåll i en berättelse påverkar uppkomsten av falska minnen, enligt DRM-paradigmet. Deltagarna för studien (30 förskolebarn i åldrarna 3-6 år) delades in i två grupper där ena gruppen hörde en positiv version av berättelsen, och andra gruppen en negativ version. Deltagarna genomgick sedan tre minnestest med cirka en veckas mellanrum, där de svarade på allmänna frågor om berättelsen, genomgick igenkänningstest med bilder, samt svarade på två suggestiva frågor.
Finngruvan - Uppföljning av vattenkvalitet, analys avavrinning och recipienter i området efter gruvdrift
This thesis raises the problem with acid mine drainage around the closed mine Finngruvan.The purpose of the investigation was to compare metal content in surface water in the areaand its catchments between year 2010 and 2003, also to make calculation of specific runoffand metal load, furthermore determine the recipients in the area. Surface water samplingwhere preformed at the same place as 2003 and also at a few other places of interest. Adigital elevation file were used in GIS to calculate the area of the watersheds in the region,observations in the field where also made. The collected data were used to make comparisons,calculations and conclusions. The result showed that the surface water 2010 had somewhatlower metal concentrations.
Skeva begär : En queerstudie av Karin Boyes lyrik
This essay examines the way the recurring motifs in Karin Boye's poetry might be read as expressions of queer or subversive desire. The fact that the lyrical I is not gendered in the poems opens up for a queer reading. In adherence to Sara Ahmed's notion of desire lines and sexual orientation I discuss the spatial aspects of desire, and explore the positions and movements of the lyrical I in Boye's poetic landscape as deviations from the concept of the straight and marked path, into the queer and unknown.I trace desire in Boye's poetry mainly through the themes of nature and night, and the ways in which these phenomena deviate from the normative structures laid out by the poems. Usually the motifs of night (such as fog, shadows and darkness) are associated with the fading of the senses. The night obscures the vision of the lyrical I and wraps them in heavy silence, making them experience and desire in new ways. Through motifs related to nature Boye formulates a feminine, matriarchal myth.

Nya tillämpningar för utandningstest kopplade till Kibions diagnostikinstrument IRIS®
The aim of my thesis is to obtain knowledge of textile wastewater and textile sludge from an environmental perspective, which can be used as a basis for the ?Sweden Textile Water Initiative? guidelines for a sustainable sludge management. In my study I have mainly focused on textile dyes, salts and metals and their routes during wastewater treatment.This paper is partly a literature review, which I began by identifying the pollutants discharged from each textile process. Then I studied wastewater and sludge quality, environmental aspects, possible treatment and recycling methods. I have also tried to find existing type of guidelines in order to make comparisons.
Konduktivitet i vattendrag som indikator på sura sulfatjordar
Increasing attention is being given to acid sulphate soils wherever they occur. The problems that leaching sulphate soils gives with significant lowerings of pH and mobilization of heavy metals influence large spectra of our society from fisheries to agriculture to construction. Mapping these soils is consequently of great importance and the methods of doing this is very much lacking in function and precision. This study was therefore carried out to investigate whether conductivity in running water can be used as a simple instrument to identify acid sulphate soils in the catchment. 31 coastal streams in the county of Västerbotten were analyzed for different catchment properties such as occurence of marine sediments and basic water chemistry including conductivity and sulphate.
Det konkreta exemplet : En diskussion kring marginaler
The following inquiry begins with one simple question: who is the margin? In other words, what is the referent of the term margin? Is it possible for language to capture connotations of an intended and supposed reality beyond its own limits? My supposition is that margin is a valuable concept to critical studies of the hegemonic order and dominant culture in various contexts. It is therefore necessary to expose the term itself to a critical analysis by attempting to trace its position in different discourses. The intention is to illustrate that the term margin is not merely an abstraction, confined within the framework of intricate theoretical rhetoric.In a deconstructive analysis of Gender Trouble by Judith Butler and Can the Subaltern Speak? by Gayatri Chakravorty Spivak, based on the work of Jacques Derrida, I study the significance of the term margin and explore how the use or non-use of concrete examples affects the reception of both the term margin and ultimately the text as a whole.The study of these two texts reveals that some of the very same critique raised by Butler and Spivak is itself applicable to the authors? own theory production.
Kritikens plats på Dagens Nyheters kultursidor 1997 och 2007
This study examines the state of criticism in the arts section of Sweden?s largest newspaper Dagens Nyheter. The study stems from raised concerns about the failing position of arts criticism, dubbed ?the crisis of criticism?. Through an overview it compares the arts section of February 1997 to the arts section of 2007.
Tungmetallers påverkan på bottenfaunans artsammansättning i sjön Tisken
The purpose of this study was to investigate how elevated levels of heavy metals affect the faunal species composition, abundance and species-diversity. The bentic macroinvertebrate fauna in the highly polluted lake Tisken was compared with the bentic macroinvertebrate fauna in the unpolluted lake Varpan. Mine wastes account for most of the metal that is discharged into Tisken. The hypotheses was that the heavy metal pollutions in lake Tisken influenced the species composition, abundance and diversity of the macroinvertebrates. Twenty samples were taken in both sites.
Den svenska kärnkraftspolitiken : En processpårande fallstudie av svensk kärnkraftspolitik
This study deals with Swedish nuclear-energy politics from 1980 to 2006. The purpose is to trace and to explain change and stability in three political parties? rhetoric concerning the phase-out of Swedish nuclear-energy and the Swedish government?s nuclear politics. Two hypotheses based on path dependency theory are tested to analyze if rhetoric and politics are developing in separate directions. The first hypothesis is based on the idea that earlier promises from the political parties affect what promises they can make later on.
En studie av metodbyte vid sintring av hårdmetaller till mikrovågsintring samt dess ekonomiska fördelar : Självständigt arbete i teknisk fysik med materialvetenskap & Självständigt arbete i kemiteknik
The aim with this study was to investigate the effects a change of manufacturing process would have on the mechanical properties of drill bits made of a WC/Co composite used for stone cutting. The method used today is sintering, where the material is heated in a conventional sintering oven. The other method was microwave sintering, where the material is heated by radiation in the microwave region. Also an investigation of the manufacturing cost were made.The main difference between the two heating methods is that the conventional way is a rather slow process and the microwave method is very fast. The material is also heated homogeniously in the method with mirowaves, aposed to the case with the conventional sintering where the material is heated from the outside in.This makes the material harder and more wear resistent.
Urinsorterande toaletter : rensning av stopp samt uppsamling och attityder
It is important that the current urine separating systems are evaluated to allow improvements to be made and consequently increase their future propagation. In order to increase the knowledge about urine separating systems this study was made. It included, among other things, measurements of amounts of urine as well as of the composition of urine collected at Nytorgsgatan 4 in the city of Hallsberg. The study was increased after an inquiry that also included the district of Understenshöjden in the city of Stockholm. In the inquiry, the users were asked questions about odour, cleaning of toilets and occurrence of blockages in the urine water locks etc.
Vattendraget på Kåbo golfbana : en kartläggning som ett steg i golfklubbens miljöarbete
This degree project studied surface waters on Kåbo Golf Course in Uppsala, Sweden, with the aim of determining the status of the water and how it is affected by the activities of the golf club, and to obtain suggestions of measures to create better conditions for the water environment on and around the golf course. The project forms part of the environmental protection work of Kåbo Golf Club, which is working towards achieving environmental certification from the Swedish Golf Association (SGF).
The study is based on literature studies and quantitative and qualitative field studies of water on the golf course, with the focus on environmental factors identified as being important for the golf industry and on strategic environmental goals developed by SGF.
The number of open water bodies in the Swedish landscape has substantially declined during
the past 200 years, so it is important to save those that remain. This study showed that the surface water at Kåbo Golf Course is an important element in the surroundings since the area contains few wetlands, which can be a habitat for large numbers of species. The stream and ponds on Kåbo Golf Course also have the important function of serving as water hazards in the game and adding difficulty and variety to the course. Since Kåbo Golf Club wants its surface waters to look aesthetically appealing, extensive algal growth and drying up of ponds during parts of the year are regarded as problems.
Kvalitet i brödvete :
The quality of bread wheat is a large subject to study. The quality rests on two legs. The first one is the inheritance of specific characters, which can be influenced through plant breeding and type of cultivar. The other one is the environmental influences, such as crop rotation, nutrition, harvest and storage. The latter factors are possibly to affect through cultivation practices, while other factors are not possible to influence on for the grower, such as seasonal changes of weather and the soil content.
Dada ser första världskriget i Berlin : En studie av kopplingen mellan George Groszs, Hannah Höchs samt Raoul Hausmanns visuella konst och första världskriget
The First World War had a definite impact on all of Europe, not to say the entire world. The domain of art was no exception. In Zürich, neutral Switzerland, a group of young creative intellectuals who shared a hostile approach towards the structure of the bourgeois society, with its non-democratic rulers and current nationalism which lead up to the war, united under the artistic movement we today call Dadaism. After the war Dadaism sprung up in several cities throughout Europe, among those Berlin. In Berlin Dadaism became a socialist weapon of propaganda, with its norm breaking artistic manifestations, against the camouflaged conservative government of the new Weimar republic.
