  1. 1. Heat-transfer Enhancement for Slurries from Biogas Plants− Properties, processes, and thermal systems

    Författare :Jingjing Chen; Xiaoyan Ji; Bona Lu; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; heat-transfer enhancement; slurry; rheological properties; computational fluid dynamics; twisted tubes; biogas production; Energiteknik; Energy Engineering;

    Sammanfattning :  Biomethane production from renewable residues with anaerobic digestion gains increasing attention as a crucial alternative to petroleum fuels. It has been vigorously developed, but the large amounts of subsidy from the government indicate that the process efficiency needs to be further improved. LÄS MER

    Sammanfattning : It is the aim of the present study to detect the reasons for these grievances, taking as an example the new Ecological Housing Estate Flintenbreite, and to demonstrate alternative solutions. For this purpose, different concepts of assessment are employed which meet the requirements of a full life cycle analysis. LÄS MER

  4. 3. Physiological and biomechanical aspects of rifle carriage during biathlon skiing

    Författare :Malin Jonsson Kårström; Marko Laaksonen; Kerry McGawley; Guillaume Millet; Mittuniversitetet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; 3D-measurement; anaerobic energy contribution; crosscountry skiing; kinematics; lactate threshold; load carriage; oxygen uptake; performance; sex differences; sub-techniques; training;

    Sammanfattning : Biathlon is an endurance-based winter sport that combines crosscountry (XC) skiing with rifle marksmanship. While skiing, biathletes carry the rifle (weighing ≥ 3.5 kg) on their backs. However, research regarding the effects of rifle carriage in biathlon is lacking. LÄS MER

  5. 4. Anaerobic Digester Fluid Rheology and Process Efficiency : Interactions of Substrate Composition, Trace Element Availability, and Microbial Activity

    Författare :Luka Šafarič; Annika Björn; Sepehr Shakeri Yekta; David Bastviken; David C Stuckey; Linköpings universitet; []
