  1. 1. Pro- and anticoagulant activities of factor V

    Författare :Elisabeth Thorelli; Malmö Klinisk kemi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Klinisk kemi; Clinical chemistry; activated protein C; protein S; factor VIII; factor V; procoagulant; anticoagulant; Haematology; extracellular fluids; Hematologi; extracellulära vätskor;

    Sammanfattning : Coagulation factor V (FV) is activated by thrombin through proteolytic cleavage at Arg-709, Arg-1018 and Arg-1545. Upon thrombin activation, the active form of factor V (FVa) is formed. FVa functions as a cofactor to factor Xa in the conversion of prothrombin to thrombin during coagulation. LÄS MER

  3. 2. Loss Mechanisms In Non-Fullerene Organic Solar Cells

    Författare :Huotian Zhang; Feng Gao; Olle Inganäs; Weimin Chen; Jenny Nelson; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; photovoltaics; organic solar cell; non-fullerene; charge recombination; voltage loss; fill factor;

    Sammanfattning : Photovoltaics are one of the most important sustainable energy sources in the 21st century. Among photovoltaics, organic solar cells (OSCs) offer many advantages such as ease of processing, lightweight, the potential for flexibility, and tunable properties. Its peculiar nature and complexity present a fascinating charm, attracting many researchers. LÄS MER

  4. 3. The effects of damping treatment on the sound transmission loss of honeycomb panels

    Författare :Sathish Kumar Ramanathan; Leping Feng; Alexander Peiffer; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Sandwich Structures; Honeycomb Panels; Sound Transmission; Loss Factor; Damping; Sound Radiation; Acoustics; Akustik;

    Sammanfattning : In the industry, all passenger vehicles are treated with damping materials to reduce structure-borne sound. Though these damping materials are effective to attenuate structure-borne sound, they have little or no effect on the air-borne sound transmission. LÄS MER

  5. 4. Perception of disturbing sounds : Investigations of people with hearing loss and normal hearing

    Författare :Åsa Skagerstrand; Stefan Stenfelt; Susanne Köbler; Stig Arlinger; Arne Leijon; Örebro universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; perception; annoyance; loudness; hearing loss; Handikappvetenskap; Disability Science;

    Sammanfattning : The present thesis concerns the daily sound environment and the human perception of the same. The sound environment affects the possibility to be active in a communication. With background noise, it may be harder to hear desired signals, and when suffering from a hearing loss, negative effects of the background noise increase. LÄS MER

  7. 5. Effectiveness of implant therapy in Sweden

    Författare :Jan Derks; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; dental implants; patient outcome assessment; implant loss; peri-implantitis; prevalence; risk factor;

    Sammanfattning : Dental implants are commonly used in restorative therapy in patients with partial or full edentulism. Knowledge regarding the outcome of this kind of treatment has been limited to evaluations of efficacy, i.e. therapy performed under optimal conditions. LÄS MER
