  1. 16. Physiological effects of conditioned medium and passage number on Spodoptera frugiperda Sf9 serum free cultures

    Författare :Ingrid Svensson; Lena Häggström; Mats Martinelle; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biotechnology; Spodoptera frugiperda Sf9; insect cell cultures; conditioned medium; cell cycle phase dynamics; proteolytic activity; antibacterial activity; recombinant protein production; Bioteknik; Bioengineering; Bioteknik;

    Sammanfattning : The aim of this study was to better understand the role of conditioned medium (CM) in Spodoptera frugiperda Sf9 insect cell proliferation and recombinant protein production using the baculovirus expression system. CM was found to stimulate cell proliferation. LÄS MER

  3. 17. Techniques for Localization of Insulation Degradation along Medium-Voltage Power Cables

    Författare :Ruslan Papazyan; Roland Eriksson; Fred Steennis; KTH; []

    Sammanfattning : Time Domain Reflectometry (TDR) has been used for localization of transmission line discontinuities in diverse applications. Various challenges have to be addressed when applying TDR for localization of insulation degradation in power cables. LÄS MER

  4. 18. Diabetes in 3D : β-cell mass assessments in disease models & evaluation of SPECT based imaging

    Författare :Saba Parween; Ulf Ahlgren; Helena Edlund; Eckhard Lammert; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Optical projection tomography; Diabetes; β-cell mass; disease etiology; 3D imaging; radiotracers; Single photon emission computed tomography; molekylär medicin genetik och patologi ; molecular medicine  genetics and pathology ;

    Sammanfattning : Diabetes is a rapidly growing disease with 415 million affected adults worldwide. The pancreatic endocrine cells, most importantly the insulin producing β-cells, play an important role in regulating blood glucose homeostasis. LÄS MER

  5. 19. Computational Materials Design of Medium Mn Steels

    Författare :Fei Huyan; Annika Borgenstam; Peter Hedström; Marcel Somers; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Medium Mn steels (~ 3–10 mass % Mn), a new category of advanced high strength steels, attracted worldwide research interests recent years due to their excellent mechanical properties and low cost. These steels have fine microstructures and contain large fraction of metastable retained austenite (~ 30 volume %), therefore exhibit excellent strength and elongation. LÄS MER

  7. 20. Heat and Mass Transfer Investigations of Relevance for Food Engineering Applications

    Författare :Dirk Sterner; Värmeöverföring; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Thermal engineering; applied thermodynamics; Termisk teknik; termodynamik; mathematical modelling; frozen and non-frozen food; minced beef patties; cooking; heat and mass transfer; plate heat exchangers; evaporation;

    Sammanfattning : This thesis concerns two interrelated subjects of heat and mass transfer processes. The first one concerns mainly experimental measurements, with a subsequent development of a calculation procedure, of the thermal and hydraulic performances, experimental methods and evaluation procedures applied on various plate heat exchangers (PHEs) as evaporators with the refrigerant ammonia as working medium.
