    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; low-temperature district heating; active thermal micro-grid; substation operation; performance assessment; distributed heat resources; chauffage urbain basse température; micro-réseaux de chaleur urbains actifs; fonctionnement de la sous-station; évaluation de la performance; sources de chaleur distribuées; lågtemperatur fjärrvärme; aktiv fjärrvärmemikronät; fjärrvärmecentral operation; prestationsbedömning; distribuerada värmekällor; Energy Technology; Energiteknik;

    Sammanfattning : Energy use in the urban environment is vital for the proper functioning of our society, and in particular, comfort heating –or cooling– is a central element of our energy system often taken for granted. Within this context, district energy systems and especially, district heating (DH) systems must evolve to adapt to the upcoming decades-long transition towards a sustainable energy system. LÄS MER

  3. 17. Investigation of genes and proteins involved in xylan biosynthesis

    Författare :Anders Winzell; Ines Ezcurra; Johan Edqvist; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Populus; xylan biosynthesis; hemicellulose; glycosyltransferase; GT43; IRX; glycoside hydrolase; GH10; Xyn10A; CAZy; transcription factor; MYB; wood formation; secondary cell wall; Arabidopsis; Molecular biology; Molekylärbiologi;

    Sammanfattning : Wood formation or xylogenesis is a fundamental process for so diverse issues as industry, shelter and a sustainable environment. Wood is comprised of secondary xylem, rigid large cells with thick cell walls that are lignified. LÄS MER

  4. 18. Chemokine Receptor CCR9: Studies on the Generation and Localization of Gut Tropic Lymphocytes

    Författare :Marcus Svensson Frej; Immunologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; small intestine; transplantation; serologi; CCR9; CCL25; chemokines; lymphocyte homing; Immunology; serology; Immunologi;

    Sammanfattning : Lymphocytes are important mediators of adaptive immune responses. Naive T lymphocytes circulate in the blood and lymph between different secondary lymphoid organs in search for their specific antigen. LÄS MER

  5. 19. Laminar and turbulent particle laden flows : a numerical and experimental study

    Författare :Seyed Hamid Tabaeikazerooni; Luca Brandt; Jeanette Hussong; Raffaella Ocone; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Suspension flow; inertial effect; turbulent duct flow; finite-size particles; Immersed Boundary Method IBM ; Astigmatism Particle Tracking Velocimetry APTV ; Engineering Mechanics; Teknisk mekanik;

    Sammanfattning : Particle laden flows are widespread in nature and in industrial applications. Dust storms, geophysical flows, pharmaceutical processes, fluidized beds and blood flow are only a few examples. Both global and local properties of a particle laden flow may alter significantly in comparison to the corresponding single phase flow. LÄS MER

  7. 20. Experimental Traumatic Brain Injury and Cell Death - in vivo and in vitro aspects

    Författare :Gustav Mattiasson; Sektion IV; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; neurofysiologi; neuropsychology; Neurology; uncoupling protein; mitochondrial permeability transition; cerebral blood flow; functional outcome; cell death; mitochondria; hippocampus; preconditioning; trauma; Brain; ischemia; neuropsykologi; Neurologi; neurophysiology;

    Sammanfattning : Traumatic and ischemic brain damage are major causes of disability and death. While much effort has been spent on developing pharmacological treatments for these conditions, no neuroprotective drugs are in clinical use. LÄS MER
