  1. 1. Bio-coal for the sustainable industry : A scientific approach to optimizing production, storage, and usages

    Författare :Aekjuthon Phounglamcheik; Kentaro Umeki; Markus Broström; Capucine Dupont; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energiteknik; Energy Engineering;

    Sammanfattning : Bio-coal produced from biomass is a promising material to replace fossil coal in order to achieve net-zero greenhouse gas emission from the industrial sector. Bio-coal with quality comparable to that of fossil coal can be produced by high-temperature pyrolysis at ≥500 ºC, but the production efficiency is relatively low due to low bio-coal yield at high pyrolysis temperatures.

  2. 2. Design of renewable and functional polyamides and polyhydroxyurethanes with tunable structure-property relationships

    Författare :Charalampos Pronoitis; Karin Odelius; Minna Hakkarainen; Stefan Naumann; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; polyamide; polyhydroxyurethane; polyester; ring-opening aminolysis; ring-opening polymerization; covalent adaptable network; copolymer; complex architecture; polyamid; polyhydroxyuretan; polyester; ringöppningsaminolys; ringöppningspolymerisation; dynamiska nätverk; sampolymer; komplex arkitektur; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Sammanfattning : Redesigning polymeric materials and rethinking their use is imperative in the prospect of a more sustainable future. Critical aspects in this endeavor are the use of renewable monomers to decrease the environmental footprint, implementing green syntheses and production processes and the design for increased recyclability as an end-of-life option to diverge from the generation of plastic waste.

  3. 3. The economics of residual waste : policies, price discrimination, and welfare

    Författare :Sef Meens-Eriksson; David Granlund; Runar Brännlund; Thomas Broberg; Raymond Gradus; Umeå universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Waste economics; net social cost analysis; waste incineration; municipal waste policy; waste taxes; price discrimination; spatial competition; welfare effects; Economics; nationalekonomi;

    Sammanfattning : Paper [I]: In this study, a net social cost framework is applied to provide insights on policy issues relating to the cross-border trade in waste fuel. We estimate the net social cost of using imported waste fuel in a highly efficient combined heat and power plant (CHP) in a cold climate by considering both private costs and benefits as well as external costs related to energy production, alternative waste management and fuel transport.

  4. 4. Facilitating Automated Compliance Checking of Processes against Safety Standards

    Författare :Julieth Patricia Castellanos Ardila; Barbara Gallina; Faiz UL Muram; Rory O'Connor; Mälardalens högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Automated Compliance Checking; Safety-critical Systems; Safety Standards Formalization; Safety Processes; Computer Science; datavetenskap;

    Sammanfattning : A system is safety-critical if its malfunctioning could have catastrophic consequences for people, property or the environment, e.g., the failure in a car's braking system could be potentially tragic. To produce such type of systems, special procedures, and strategies, that permit their safer deployment into society, should be used. LÄS MER

  5. 5. The making of the engineering student : A study examining the societal and cultural production of the subject, the engineering student

    Författare :Patricia Kingdon; Lars Geschwind; Sven Ove Hansson; Ulf Olsson; Maria Andrée; KTH; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Engineering education; recruitment to engineering education; broadening of the recruitment base to higher education; power and knowledge; underrepresented student groups at technical universities; Nyckelord: civilingenjörsutbildningen; högskoleingenjörsutbildningen; rekryteringen till tekniska utbildningar i högre utbildning. makt och kunskap; underrepresterade studentgrupper. val av utbildning; rekrytering.; Teknikvetenskapens lärande och kommunikation; Education and Communication in the Technological Sciences;

    Sammanfattning : AbstractThis thesis makes a novel and original contribution to the discourse surrounding engineering education, and how it can be made more accessible to underrepresented groups. The study includes two contexts representing two different perspectives. LÄS MER
