  1. 31. Electronic structure and spectroscopy calculations in fuel cell catalysis

    Författare :Henrik Öberg; Lars G.M. Pettersson; Göran Lindbergh; Stockholms universitet; []
    Nyckelord :Chemical Physics; kemisk fysik;

    Sammanfattning : This thesis presents joint experimental and theoretical studies of surface phenomena at an electronic structure level in proton exchange membrane fuel cells (PEM-FC's). The fuel cell activity can be related to the oxygen reduction taking place at the cathodic surface through the oxygen reduction reaction (ORR). LÄS MER

  3. 32. Cell Behavior and the Role of Profilin

    Författare :Yu Li; Roger Karlsson; Christophe Ampe; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Cell biology; Cellbiologi; cellbiologi; Cellbiology;

    Sammanfattning : Profilin is a key regulator of the microfilament system. It binds to actin monomers in a 1:1 complex, forming the profilin:actin complex, which is the major precursor of actin for filament formation in vivo. The distribution of profilin has been studied in a variety of cells. It is present not only in the cytoplasm but also in the nucleus. LÄS MER

  4. 33. Multi-Cell Massive MIMO: Power Control and Channel Estimation

    Författare :Amin Ghazanfari; Emil Björnson; Erik G. Larsson; Dirk Slock; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Cellular network operators have witnessed significant growth in data traffic in the past few decades. This growth occurs due to the increase in the number of connected mobile devices, and further, the emerging mobile applications developed for rendering video-based on-demand services. LÄS MER

  5. 34. Cell therapy for denervated tissue

    Författare :Roine El-Habta; Ludvig J. Backman; Paul J. Kingham; Patrik Danielson; António Salgado; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; adipose tissue-derived stem cell; cell therapy; denervation; differentiation; myoblast; peripheral nerve injury; proliferation; regeneration; skeletal muscle; stromal vascular fraction; survival; tendon; cellforskning; cell research; Medical Cell Biology; medicinsk cellbiologi;

    Sammanfattning : Background: Peripheral nerve injury results in denervation of tendons and muscles. The biology of denervated muscle has been well studied but little is known about the associated tendons. LÄS MER

  7. 35. Cell-Free Massive MIMO: Distributed Signal Processing and Energy Efficiency

    Författare :Zakir Hussain Shaik; Erik G. Larsson; Emil Björnson; Saikat Chatterjee; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : In this era of rapid wireless technological advancements, wireless connectivity between humans, humans with machines, and machines with machines is gradually becoming an absolute necessity. The initial motivation for wireless connectivity was to enable voice communication between humans over a geo-graphical area. LÄS MER
