  1. 1. Conversion of Biomass to Renewable Liquid Feedstocks in Pyrolysis-based Applications

    Författare :Henry Persson; Weihong Yang; Louise Olsson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Pyrolysis; Biomass; Pre-treatment; Stepwise Pyrolysis; Catalytic Pyrolysis; Pyrolys; Biomassa; Förbehandling; Stegvis Pyrolys; Katalytisk Pyrolys; Teknisk materialvetenskap; Materials Science and Engineering;

    Sammanfattning : The production of chemicals and fuels currently rely on fossil resources which are associated with global warming as well as economic and political instabilities. The demand for renewable alternatives is increasing as legislations on greenhouse gas emissions are becoming more stringent. LÄS MER

  3. 2. Vara - Framträdande - Värld : Fenomenets negativitet hos Martin Heidegger, Jan Patočka och Eugen Fink

    Författare :Krystof Kasprzak; Marcia Sá Cavalcante Schuback; Susanna Lindberg; Södertörns högskola; []
    Nyckelord :HUMANIORA; HUMANITIES; Humanities; Fink; Heidegger; Patočka; phenomenology; phenomenon; appearing; appearance; existence; movement; orgiasm; the sublime; sleep; Humaniora; Fink; Heidegger; Patočka; fenomenologi; fenomen; framträdande; sken; existens; rörelse; orgiasm; det sublima; sömn; Kritisk kulturteori; Critical and Cultural Theory; Östersjö- och Östeuropaforskning; Baltic and East European studies;

    Sammanfattning : The present investigation discusses the phenomenological concept of the phenomenon through an interpretation of the meaning of the negativity of the phenomenon in the philosophical works of Martin Heidegger, Jan Patočka and Eugen Fink. This negativity is thematised in terms of a loss and a privation that leads to a description of the appearing of the phenomenon as a sublime event, which exposes existence to an absence of meaning.

  4. 3. Continuous improvement and experience feedback in off-site construction : timber-framed module prefabrication

    Författare :John Meiling; Micke Oostra; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Träbyggnad; Timber Structures; Construction Engineering and Management; Byggproduktion;

    Sammanfattning : Continuous improvement implies an incremental, ongoing effort to improve products, services or processes. Some construction companies have chosen to face competition by adopting an off-site construction strategy, one form of which is timber-framed module prefabrication. LÄS MER

  5. 4. Arbetsintegrerad systemutveckling med kalkylprogram

    Författare :Anders Avdic; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Studieområdet för denna rapport kan formuleras: ”Människor utvecklar med hjälp av kalkylprogram, inom ramen för sina linjearbetsuppgifter, tillämpningar för eget behov, som om de gjordes med ’traditionell’ systemutveckling, skulle innebära betydligt större insatser av tid, personal och specialistkompetens”. Denna aktivitet kan ses ur ett process- produktperspektiv, där processen kallas arbetsintegrerad systemutveckling med kalkylprogram (AIS-K) och produkten kallas kalkylsystem. LÄS MER

  7. 5. Stability and sorption capacity of montmorillonite colloids : Investigation of size fractional differences and effects of γ-irradiation

    Författare :Karin Norrfors; Susanna Wold; Daniel Kaplan; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; montmorillonite; colloids; size effect; γ-irradiation; sorption; colloid stability; radionuclides; montmorillonit; kolloider; storlekseffekt; γ-bestrålning; sorption; kollodial stabilitet; radionuklider; Kemi; Chemistry;

    Sammanfattning : Bentonite clay is intended to form one of the barriers in most repositories of spent nuclear fuel located in granite. One important function of the bentonite barrier is to retard transport of radionuclides in the event of waste canister failure. Bentonite has a high sorption capacity of cations and its main constituent is montmorillonite. LÄS MER
