  1. 1. Excited State Processes in Solar Energy Materials

    Författare :Tomas Österman; Kemisk fysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Solar cells; Conjugated polymers; Charge transfer state; Time-resolved spectroscopy; Fluorescence; Artificial Photosynthesis; Bis-tridentate ruthenium II -complexes; Density functional theory; Quantum chemistry.;

    Sammanfattning : This dissertation covers studies of excited state processes in two types of solar energy materials: alternating polyfluorene polymers and their blends with fullerenes in the active layer of plastic solar cells, and bis-tridentate RuII-polypyridyl complexes to be used as sensitizer in systems for artificial photosynthesis. The polymer:fullerene blends were studied by transient absorption and time-resolved fluorescence measurements in order to investigate the role of the charge transfer (CT) state in charge formation.

  3. 2. Opinionens mekanismer : Om värderingar och verklighet

    Författare :Torsten Österman; Stefan Svallfors; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Sociology; Sociologi; Sociology; sociologi;

    Sammanfattning : A significant characteristic of our time is the accelerating speed and increased volume ofinformation, where events and information about events form an interacting dynamo. The traitsand abilities of individuals and society to handle and respond to that flow of informationdeserve political attention. LÄS MER

  4. 3. Kontinuitetsprincipen i den svenska inkomstbeskattningen

    Författare :Roger Persson Österman; Nils Mattsson; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; LAW JURISPRUDENCE; RÄTTSVETENSKAP JURIDIK;

    Sammanfattning : This dissertation deals with the principle of basis carry-over. The principle of basis carry-over makes possible generation succession and company reorganisations without the accompanying transfers and transactions resulting in taxation for the appreciation of the assets.

  5. 4. Developing a Value Proposition of Maritime Ergonomics

    Författare :Cecilia Österman; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; operational performance; socio-technical systems.; Ergonomics; value proposition; maritime economics; human element; shipping; participatory ergonomics;

    Sammanfattning : There is a large body of knowledge available on the importance of ergonomics for successful(and unsuccessful) systems. Domain specific handbooks, guidelines and standards can befound also for the maritime industry. LÄS MER

  7. 5. Ergonomics: An uncharted route to improved overall systems performance in shipping

    Författare :Cecilia Österman; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Ergonomics; human factors; quality; safety.; productivity; shipping; efficiency;

    Sammanfattning : Continuously, improved design of hull, propulsion and cargo handling systems has increased speed, capacity and reliability of sea transports. Simultaneously, efforts have been made to perfect crew size and composition in order to optimize operations costs. LÄS MER
