Handlingsplan för rening av dagvatten från hårt trafikerade gator i Örebro
The main purpose with the project has been to approximate the magnitude of the pollution transport from the actual road surfaces and to get an approximation of the possibility to collect the pollutants to reduce the load to the water and improve the water quality.The quantity of pollution transport from the most trafficated roads areas in Örebro city has been calculated. Roads whith a traffic exceeding 10 000 vehicle/day. The study has been done with the calculation tool StormTac. Through analysis of traffic loads and road surface, which together with a different kinds of parameters gives an approximation of the pollutant transport.The calculation has included some metals and other substances in the stormwater and has also included the present of suspended solids. Included the overall study, some smaller areas has also been calculated for the possibility to remove pollutants.The work also includes calculation for three different areas for stormwater treatment.
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.
En modell för optimal tobaksbeskattning - under tidsinkonsistenta preferenser och imperfekt information

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.
Utveckling av heltäckande gångbord
This thesis work is a 30hp D-level assignment in design as a co-operation between MälardalenUniversity and Scania CV AB in Södertälje. The purpose was to develope a close fitted catwalk.The market has seen an increasing value for these types of applications and have the ambition to keep up with the rest of the competitors. The catwalks of todays standards shall be estetical attractive, have a non slippery surface and be costefficient.While working with this project I have spent a lot of time with the concept proposals and with the evaluation of the concepts, resulting in a final CAD model and a approximation of the cost estimate. The new catwalk fulfils all the new recommendations and rules as sharp edges, ADR, the height of the stepup and a non slippery surface with built in drainage..

Nätverkskommunikation för jämställdhet
AbstractTitle: Network communication for equal opportunities (Nätverkskommunikation för jämställdhet)Number of pages: 47 (54 with enclosures)Author: Hillevi GoodTutor: Ylva EkströmCourse: Media and Communication Studies DPeriod: Spring Semester 2007University: Division of Media and Communication, Department of Information Science, Uppsala UniversityAim: The aim of this essay is to study the possibilities to bring about change by the means of communication in two networks, focusing on the implementation of the Swedish Equal Opportunities Act.Material and method: The study draws on data collected in an electronic survey among representatives of two networks consisting of representatives from trade unions and employer?s associations. The material is analyzed using descriptive tools, cross tables and correlation matrices in which general characteristics as well as individual understandings of the network communication are presented and discussed.Main results: The general results indicate that the network communication serves important purposes, such as providing support and motivation for the members and changing attitudes towards equal opportunities. The analysis suggests that the network members have good communicative possibilities to serve as agents of change within their organisations. Moreover, there is an observed relation between, on the one hand, organizational context and, on the other hand, the network members? own communicational behaviour and their experienced possibility to influence their organizations.Keywords: network communication, diffusion of innovations, behaviour change, Equal Opportunities Act.
Hoppa på tåget eller stå kvar vid stationen? : Organisationers användning av sociala medier
Purpose:The purpose of this paper is to investigate and clarify some of the factors that influence organizations to adopt or reject the social media, and if the emergence of social media influenced the organization's communication.Metohodology:A qualitative methodology has been used to execute the study. The source has been semi structured interviews with chosen representatives from several organizations.Theoretical perspective:The theoretical basis for the execution of the methodology is based on the provisional theoretical demarcation uses and gratifications theory. For analysis diffusion of innovations theory is applied.Emperical findings:The empirical material includes interviews with representatives from twelve selected organizations, defined as companies in the industry and authorities, in seven different industries.Conclusion: The main factors affecting an adoption of social media is the organization?s open structure, the ability to see opportunities with social media and that they are seen as a natural part of development in the communications field. The main factors affecting a rejection of social media is ignorance, the organization's governance and that there must be a need that social media can fill.
The diffusion of minimum tillage in agricultural China : a study of the factors influencing the farmers? choice of tillage system
The Chinese government´s aim to be self-sufficient in food production in combination with the increased food consumption in China has put high pressure on the productivity within the Chinese agricultural sector (He j et al, 2010). In order to increase the productivity, modernization and adoption of new farming techniques are essential. The opportunity to adopt and import foreign technology has lately been possible in China, as more authority and decision rights have been given to the individual farmers and the country has opened up for foreign trade (Zheng, 2012 & Fan, 1991).
A more open Chinese market enables new opportunities for foreign agricultural companies to expand their businesses by introducing their products to Chinese farmers. But to succeed with this strategy the Chinese farmers must be willing to adopt these, for them new innovations.
Minimum tillage is a tillage practice used worldwide that is suitable in northern China where drought and erosion are the main problems in the crop production (pers.com., Arvidsson, 2012).
Potential users? opinion of new innovations such as minimum tillage is closely related to adoption (Rogers, 2003).
