  1. 11. Models for the Procurement of Subsidized Air Services : Conventional Aircraft and the Adoption of Electric Aircraft

    Författare :Alan Kinene; Tobias Andersson Granberg; Clas Rydergren; Valentin Polishchuk; Jesper Larsen; Linköpings universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

    Sammanfattning : In liberalized air transportation markets, governments often adopt subsidy schemes through which they ensure air services along routes that are deemed commercially non-viable but economically and socially essential. The objective of these subsidized air service routes is to ensure a minimum level of services to outlying communities or remote regions that are difficult to access—by other modes of transportation—from the capital, other main cities or a hub airport yet can not be served commercially due to thin demand.

  3. 12. Performance of Conventional and Structural Lithium-Ion Batteries

    Författare :Maria Hellqvist Kjell; Göran Lindbergh; Mårten Behm; Anthony Kucernak; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Lithium-ion batteries have, in recent years, experienced a rapid development from small everyday devices towards hybrid electric vehicle (HEV) applications. Due to this shift in application area, the battery performance andits degradation with time are becoming increasingly important issues to besolved. LÄS MER

  4. 13. Aliphatic Polyesters for Soft Tissue Engineering : Development from Conventional Organometallic to Novel Enzymatic Catalysis

    Författare :Rajiv Kumar Srivastava; Ann-Christine Albertsson; Stanishaw Penzzek; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; aliphatic polyester; 1; 5-dioxepan-2-one; ε-caprolactone; L-lactide; D-lactide; D; L-lactide; enzyme; lipase CA; lipase PS; Polymer chemistry; Polymerkemi;

    Sammanfattning : The development of macromolecules with defined structure and properties, aimed specifically for biomedical applications, has resulted in diverse biodegradable polymers with advanced architectures. Among them, aliphatic polyesters synthesized by ring-opening polymerization (ROP) of lactones and lactides have a leading position due to their good mechanical properties, hydrolyzability and biocompatibility.
