Användande av diffusionsspärr vid tilläggsisolering av äldre byggnader med trästomme

In the current situation a big part ofthe settlements that exist in Sweden isin need of renovation and energyefficiency in order to survive.Therefore, also many of the older houseswith a wooden structure are in a need ofenergy efficiency, which can be done ina variety of ways, including addinginsulation.This project deals with whether the useof a Diffusion barrier or a vaporbarrier affects a wall structure byadding insulation to an older house witha timber frame. The insulation materialswhich are concidered in thisinvestigation are mineral wool and woodfiber insulation. Efforts are focused onthe effects of moisture on theseinsulation materials.To demonstrate the differences thatarise the moisture measurement programWUFI have been used to simulate avariety of wall designs. These designsare developed in consultation with theconstruction carers who are active inthe industry.Using WUFI graphs illustrating themoisture levels of the wall structureswere obtained and from these conclusionsvould be drawn. The work demonstratesthe differences that arise when using aDiffusion barrier or vapor barrier inwall construction.

Äldre och den nya världen : En kvalitativ innehållsanalys av medieanvändande hos den äldre generationen

AbstractTitle: The old generation and the New World - A qualitative content analysis of media usage of the older generationKeywords:Digital natives, digital immigrants, Diffusion of innovation, content analysisThis study has its focus on how the older generation looks at today's media society and the use of today's media. Through a method of qualitative content analysis based on questionnaires, the aim is to examine what the older generation thinks about today's media, how they use them, and whether there are differences in groups according to age and previous work.The study selected theories bases on Marc Prenskys idea of ??digital natives, digital immigrants and Everett M Rogers book on "Diffusion of Innovation". These theories take up the difference on digital natives and digital immigrants and the spread of new technological ideas takes place through communication over different channels in time among causes people in a social system.The result of the study shows that many older people are good at making use of today's media, but also that many may feel alienation of today's media society. Development has proceeded rapidly in recent years and for the older generation it's sometimes hard to keep up.The conclusion of the study is that the older generation may need more help to discover how today's media can facilitate everyday life and enrich it with more communication despite the fact that it takes place through a screen..

Introduktionen av tapeter på den svenska landsbygden 1850-1890 : en studie av attityder vid kulturspridning med utgångspunkt i Nordiska museets frågelista om tapeter

The aim of this essay is to examine how people living in the Swedish countryside looked upon changes in the interiors through modernization in 1850-90. For the first time, there was an abundance of objects available in stores in the countryside that the majority of the population had money buy. Many novelties were introduced in the interior decoration of ordinary peoples´ homes. This study focuses on the introduction and use of wallpaper and is based on a questionnaire about wallpaper sent from the Nordiska museet, National museum of Culture history in Sweden, to people all over Sweden in 1948. 148 people responded to the questions about use and attitudes toward wallpaper during the second half of the 19th century.My theoretical perspective is cultural Diffusion, the spread of cultural items, more specific the Diffusion of innovations from larger to smaller places, often influenced by social elites, hierarchical Diffusion, and between individuals, contagious Diffusion.The analytical perspective used for the analysis is based on the concepts of basic and variable modernity, initiated by the historian Sven-Eric Liedman.

Akustisk design av studiorum för musikinspelning

Detta projekt genomfördes i samarbete med akustikern Erling Nilsson på företaget Ecophon i Hyllinge. Uppdragsgivare var musikproducenten Magnus Ågren som äger studion Flow Music i Malmö. Uppgiften var att förbättra akustiken i ett av Flow Musics studiorum. Rummet hade före projektet en hård och obehaglig akustik. För att komma fram till ett åtgärdsförslag specificerades först hur enskilda akustiska egenskaper skulle påverkas för att ge ett så bra resultat som möjligt.

Kommunikation vid införande av säljstöd - en fallstudie

Trots att det görs framsteg inom hård- och mjukvaruutvecklingen, fortsätter problemen med dåligt utnyttjade system. Forskare påpekar att det är viktigt att forska vidare inom området - när informationsteknologi blir eller inte blir accepterat samt när den används inom organisationer. Det är viktigt att de anställda inom organisationen som skall använda systemet, utvecklar en positiv inställning redan från början för att Diffusionen, det vill säga den process som innefattar kommunikationen rörande en innovations införande via fastställda kanaler hos medlemmarna i ett socialt system, skall kunna genomföras så effektivt som möjligt. Forskare anser att det fordras mer forskning inom ledningens inverkan vid Diffusion, det vill säga den process som innefattar kommunikationen rörande Diffusion via fastställda kanaler hos medlemmarna inom ett socialt system. Vi har valt att undersöka hur ledaren anser att denne kommunicerat vid Diffusion, hur upplevs denna kommunikation av användaren samt vilka implikationer kan ledarens kommunikation få för användaren? Vi har valt att göra undersökningen hos Länsförsäkringar för att de nyligen infört ett nytt datainformationssystem och haft svårigheter med att få systemet accepterat.

Bitcoins adaption : En undersökning av faktorer som påverkar Svenska företagares val att implementera Bitcoin i sin verksamhet.

Många länder går mot ett samhälle där kontanter används till en mindre grad vilket har lett till en ökning av elektroniska betalningsmetoder. Utöver kortbetalningsmetoder har andra mer hög teknologiska betalningsmetoder vuxit fram. Bland dem är Bitcoin ett nytt system som vuxit sig relativt stor under de senaste åren. Bitcoin är både kritiserat och hyllat i olika medier. Utifrån de två väletablerade teorierna; Diffusion av innovation och Teknologi acceptans modellen avser studien att identifiera betydande faktorer i Svenska företags adaption av Bitcoin.

Impact of Regulations on Innovation Performances in EU:

Innovation has been identified as one of the key factors for economic growth long ago. However, the emergence of ?knowledge century? further strengthened the role of the concept since proper management of the knowledge is essential to make the best out of the innovative capacity of the companies as well as the countries. This necessitates a balanced intellectual property rights (IPR) systems, since these rights provide the basis to solve the market failures faced by innovating firms by creating property rights over knowledge. There is an inherent dilemma between invention and Diffusion.

Spinn i det nya medielandskapet : Nya medieaktörers inflytande på den traditionella journalistiken

Aim With this study we want to highlight and analyze the media spin of the PR campaign Miss Skinny by clarifying; a Diffusion pattern which covers posts published by bloggers and journalists; a framing pattern from the first audited post to the last; how journalists are influenced by user generated content, and what consequences this may have for the news coverage.Method We have conducted a studied of news posts and blog posts about the Swedish PR campaign Miss Skinny through content analysis, Diffusion analysis and mapped direct links between blog posts and news posts.Main result We found that a surprisingly large amount of news postings contained direct links to previous blog posts and that the former media serial no longer can be applied on today's modern media where journalists and other players come together on the converged media arena. .

På spaning efter drivkrafter och rötter: En motivanalys av drivkrafter inom Sveriges Pensionärers Intresseparti samt om inspirationskällor vid partiets uppkomst

One aim of this thesis has been to trace the driving forces among active members of the Swedish Pensioners? Interest Party (SPI), but also to render how party values and ideas are connected to the concepts of is-sue space, distrust, and New Party Politics (mainly populism). Since there are several pensioners? parties in other countries, my second aim has been to investigate whether the party is a result of a Diffusion proc-ess of copying a successful equivalent party; in other words to find out whether a master frame has inspired the forming of a Swedish pension-ers? party. Through interviews and document analysis, I have found seven issue dimensions explaining the motives behind my respondents? engagement in the party.

När tar man fram kondomen? : En studie om lärares attityder till UR och RFSU:s projekt för en bättre sexualundervisning

The debate in the media on a new Swedish sex education movie sparked our interest in this study. The twenty-eight minutes long movie ?Sex on the map? is the first of it?s kind in twenty-five years. It is also part of a bigger sex educational project that contains, apart from the movie, a book about sex education, a documentary and a teachers guide. The project is a co-production between the Swedish Educational Broadcasting Company (UR) and the Swedish Association for Sexuality Education (RFSU).We were interested in how teachers received information about the project, and what their attitudes were towards it.

I förändringens spår En undersökning av referensbibliotekariers accepterande av tillgängliggörandet och användandet av databaser på och via folkbibliotek

In Sweden most public libraries give users access to databases. These databases are sometimes possible to reach outside the library by internet at any time and this provides a change for the library and the society. Librarians function as change agents when they give access to databases and when databases are introduced to users. However, reports show that the use of databases, especially those in English, is not high in reference work. This study aims at analysing attitudes of librarians to access and use of databases on and by public libraries.

Koncentrisk hämning och stimulans av bakterietillväxt i agarkulturer

The aim of this study is to elucidate factors that effect growth of Sarcina lutea and Bacillus subtilis, exposed to the growth inhibitor SDS (Sodiumdodecylsulfat). Agar Diffusion experiments revealed repeated, concentric zones of inhibition and stimulation upon exposure to Sodiumdodecylsulphate or to Amoxicillin. Temperature, nutrient concentration and inhibitor concentration were controlled. Formation of successively repeated zones of inhibition, stimulation, inhibition and stimulation is discussed: ? The extension of the primary inhibition zone is due to the concentration of applied Sodium dodecyl sulphate.? Immediately outside the primary inhibition zone the bacteria have access to diffusing nutrients that have not been consumed in the primary inhabitation zone.? In zones of dense bacterial growth the bacteria may produce inhibiting substances, affecting growth of bacteria in adjacent zones.? In zones of dense bacterial growth the nutrients will soon become depleted, thus affecting bacteria in adjacent zones..

Implementering av Virtuellt Byggande i byggprocessen : Fallstudie av NCC Construction Sverige AB

Virtual Design and Construction (VDC) is the definition for using BIM in the construction process to simulate and analyse the building. Resulting use of the technology will according to proponents lead to fewer construction errors, a better understanding between stakeholders for the construction project, less communication problems and a smoother construction process. Although BIM has according to researchers a big potential, few companies have succeeded in broad and continues implementation. The study aims to identify the factors affecting the implementation. More precisely identify what factors influencing the decision to adopt VDC and potential barriers in the Diffusion process. The empirical findings are based on a case study of NCC Construction Sweden.
