Optical and Structural Properties of CuxS Quantum Dots Concerning H2O/Ethanol Solvent Ratio
Nanotechnology, one of the most interesting sciences today will no doubt have an enourmous impact on tomorrow's society and industry. One of the most interesting nanomaterial that has been discovered is the semiconductor quantum dot (QD). This material shows interesting novel properties such as a size-dependent band gap, which is an effect caused by the quantum confinement effect in all three dimensions. Due to this phenomenon the absorption spectrum can be tuned to the desired value by adjusting the size of the QD.This thesis aims to investigate how the solvent ratio of H2O/Ethanol affects the optical and structural properties of copper sulfide QDs manufactured in a chemical synthesis way using modern microwave heating. The process of manufacturing QDs using chemical synthesis often involve a capping-agent to prevent the QDs from agglomerate into bigger structures.
European Union Politics ? en tidskrift och dess invisible college
Author Cocitation Analysis (ACA), multidimensional scaling (MDS) and Social Network Analysis (SNA), has been used to analyze and visualize the invisible college of the journal European Union Politics. The concept invisible college was first introduced in the fifteenth century, through the creation of the ?the Royal Society of London?, and it was reintroduced in the 1960:ies and the 1970:ies by scholars such as Price and Crane. It is said to have been interpreted in as many ways as there are authors who have used it. Here it has been used synonymously with the term citation network.
Sand pits as habitat for ground beetles (Carabidae) : does the area affect species number and composition?
Sand pits are a valuable habitat which can hold many sand living species including several endangered ones. As many sand habitats with exposed sand are declining, sand pits have a potential as a substitute habitat. This study was conducted to see what effect the area of a sand pit has on species number and composition of ground beetles (Coleoptera: Carabidae). Also, the effects of other environmental variables were tested, for example the proportion open sand, vegetation cover, sun exposure and tree cover. The study was conducted in the county of Uppsala in 2008 and included 13 sand pits with areas between 200 and 180,000 m2.
Unga vuxna med unilateral läpp-, käk- och gomspalt ? perceptuell bedömning och självskattning av tal och kommunikation
The purpose of this study was to investigate how young adults withunilateral cleft lip and palate assess their own speech and communication,and to let speech and language pathologists make a perceptual analysis ofthese individuals? speech at the age of 19 years. An additional aim was toexamine the relationship between these two different ways of evaluation.Data was collected through perceptual analysis from audio recordings and byusing a self-report questionnaire based on the ICF-structure (InternationalClassification of Function, disability and health). Altogether, 33 peopleparticipated. One third of the participants had no speech deficiencies.
Rutavdraget för läxhjälp : En studie av regeringens interventionslogik och nyckelpersoners uppfattningar i Linköpings kommun
The main purpose of our paper is to reconstruct the intervention logic of the Swedish government's proposal to introduce a tax deduction for homework help. Furthermore, we also intend to outline the perceived impacts of this tax deduction in the municipality of Linköping. Our material consists of the government bill regarding the tax deduction, the parliamentary debate which preceded it as well as interviews with key people in the municipality of Linköping. In our study and in the light of Matthew Clarke?s theory of neo-liberalism within education policy, we also ask ourselves if the intervention logic behind the tax deduction and its perceived effects can be seen as a manifestation of neo-liberalism.
Synen på hemlöshet : En diskursanalys av hemlöshetsarbetet i Norrköpings kommun
The aim of this paper is to see how the local authorities in Norrköping create a way to look at homelessness. This aim is examined with the help of the central questions: How does the municipality describe homelessness as a phenomenon? What causes to homelessness can be seen in the texts? How do they describe homeless people? And What kind of actions are used or proposed? The analysis has been done with the tools and thoughts of the critical discourse analysis and made on text documents written by politics and employees of the city of Norrköping. The theories which have been used are those of postmodernism, welfare, homelessness, civil society and relative poverty. The analysis shows that the way the municipality of Norrköping looks at homelessness correspond with the way homelessness is presented in current Swedish research.
SAB-systemet och Yahoo! En jämförelse rörande traditionell och ny klassifikation
The aim of this Master thesis is to investigate the similarities and differences between a traditional and a new classification scheme. Two classification systems are compared, "The Swedish Library Classification System" the SAB-system - and Yahoo!. The SAB-system has been used in Swedish libraries since the beginning of the 20^th century, and Yahoo! has been online since 1994. Yahoo! has a Swedish version of its international original, which is used in this study to get a similar starting point with the SAB-system. The method used for this is a content analysis, which in this case is not a quantitative analysis.
Osynliga nyhetsoffer eller som du och jag : Framställningen av personer med funktionsnedsättning i Rapport och TV4 Nyheterna
In this study we examine to what extent people with disability participate in television news and how they are represented. We chose to examine one broadcast per day of SVT Public Service news program Rapport and commercial channel TV4 Nyheterna (TV4 News) during one month using quantitative content analysis and qualitative discourse analysis.We found that people with disability are underrepresented in television news. In Rapport only 1,9 percent of the total broadcasting time contained people with disability and in TV4 Nyheterna 3 percent of the total broadcasting time contained people with disability. In the news people with disability were often represented as stereotypes, most commonly as victims. The focus was often on the medical aspect of the disability and on the problems that people with disability had.
Sverigedemokraternas framgångar i kommunalvalen 2006 och 2010
This essay examines the recent electoral success of the Sweden Democrats (SD) in the Swedish municipal election in 2006 and 2010. By using statistical methods it aims to explain which of three contradicting theoretical frameworks best can explain how a populist radical right party could penetrate one of the most stable party systems in the world. The theoretical approaches tested in this essay are: a demand-side, an external supply-side and an internal supply-side approach. By using theoretically anchored proxies to determine the effect of the contradicting theoretical approaches this essay concludes that the internal supply-side explanation measuring the local party organizational ability of the SD had the most substantial effect when it comes to explaining their recent electoral success in the Swedish municipalities, as opposed to a more commonly believed demand-side driven explanation..
Gringo - en språklig förnyare men hur? : En genre- och stilanalys av ett nytt samhällsmagasin över kulturgränser
The essay is an effort to examine and define three examples of liminal dance performances through an aesthetic, hermeneutic and semiotic analysis. The examples are three dance or liminal performances, made by three different choreographers and performed at ?Moderna Dansteatern? and ?Dansens Hus? in Stockholm during September and October 2005. In the effort to determine the liminal and cross-over in the performances, the analysis focus on aspects such as: the character of the work, choreography, the use of scenery, stage light, requisites, conception of place and interior room, the use of costume and mask, the use of different media as text, pictures, film, and music or not using any these, and the interaction with the audience. The analysis depends on a historical background and the use of literature in the subject.
"Ya know, I don't mind being labeled a crackhead." : En semiotisk analys av hur tv-spelet Grand Theft Auto V skildrar hudfärg, klass och kön
The purpose of this thesis is to examine the representation of race, social class and gender in the 2013 video game Grand Theft Auto V. Postcolonial theory, including terms such as cultural hegemony, whiteness and Michel Foucaults definition of power, has served as the basis for the analysis. The postcolonial theory has been combined with class theory and gender theory for an intersectional analysis. Semiotic analysis has been used as the method in the thesis, and a total of nine story missions ? three for each protagonist in the game ? have constituted the material.
Deltid och kön: En undersökning av deltidsarbetets utveckling under åren 1987-2005
This paper aims at assessing the relationship between female and male part-time employment and the business cycle in Sweden during the years 1987?2005 using quarterly time-series data and two alternative indicators of the business cycle. It further aims at determining whether the share of women working part-time has changed over time. Key results include that the relationship between the business cycle and female part-time employment is found to be significant and countercyclical. No significant effect is however found for men.
Hållbarhetslivscykelanalys på kakel och klinker : Analys av vägen från vagga till grav ur ett hållbarhetsperspektiv
In this report two Sustainability Life Cycle Assessments are carried out for two types of tiles for Riksbyggen, to contribute to a sustainable urban transition. Sustainability Life Cycle Assessment involves performing a life cycle assessment based on four principles based on scientific research and presented by the non- governmental, non-profit organization, The Natural Step. The principles concern raw materials, chemically produced substances, degeneration of nature and social conditions.Origin of products, manufacturing sites and manufacturing procedures were initially completely unknown and much of the work has consisted of finding the entire cycles, understand manufacturing processes of ceramic tiles and evaluating what materials and what type of energy sources that are required for the production. A socially sustainable perspective has been of high relevance alongside an ecologically sustainable perspective.The report begins with the basic underlying facts and the purposes of this investigation and that the reasons why Sustainability Life Cycle Assessments are carried out are to provide Riksbyggen and the own workers with documents presenting Riksbyggens ideas regarding sustainability and to hopefully get the ideas further down in the supply chain. The methods used to fulfill the investigation are presented and scientific facts about LCA and ceramic building materials are reviewed.
The effect of vegetable fat on cheese yield and cheese properties
The production of cheese is in continuous development with objectives to in-crease productivity, achieve changes in shelf life and functional properties of the products. One concept in the development is to substitute milk fat with vegetable fats and oils in the manufacture of cheese.
The objective of this study was to investigate effects on cheese yield and cheese quality of 4 different semi-hard analogue cheese products produced by substituting milk fat with vegetable fat, each analogue cheese with a specific mixture of vegeta-ble fat. As reference a cheese produced with anhydrous milk fat was used.
The yield and recovery of fat and protein were determined by recording the weights of each cheese direct after press and after 20±2 days of storage and analysis of the composition of the cheeses after 20±2 days of storage. The cheese was fur-ther subjected for texture profile analysis in a TA-XT Plus Texture Analyser and analysed with Differential Scanning Calorimetry (DSC) to examine whether the fat behaves similar in the cheese as in pure form in respect to its thermal properties.
The cheese yield was not significantly different when using different fats. Differ-ent amounts of water were absorbed during the water cooling.
"Det är såhär en riktig man ska vara" : En retorisk analys av hur manlighet framställs i podcasts
This study examines how masculinity is portrayed in podcasts. Our original materialconsisted of four episodes of C/o Hannah & Amanda and four episodes of Filip &Fredrik's podcast. We analyzed the programs both individually and in comparison toeach other. Using a rhetorical analysis, we found that the perception of men in thepodcasts conforms to societal norms. The theoretical basis underlying ouranalysis can be expected to strengthen our findings and made us also realize that theimage of masculinity is constantly evolving..
