1. 1. Novel bioinspired and biohybrid electrode materials for hydrogen production

   Författare :Afridi Zamader; Gustav Berggren; Vincent Artero; Marc Robert; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Device; H2; [FeFe] hydrogenases; inspiration; catalyst; multiwalled carbon nanotubes; life cycle assesments; semisynthetic hydrogenases; Kemi; Chemistry; Biokemi; Biochemistry;

   Sammanfattning : This thesis was accomplished under the scope of eSCALED project administrated by EU MSCA horizon 2020 program, which aimed to develop a device called “artificial leaf” responsible for generating fuels or liquid chemicals (H2 production or CO2 reduction) using solar electrolysis. My objective was to develop a noble metal free, efficient cathode materials for H2 production for the device which yield this thesis. LÄS MER

3. 2. Health-related quality of life in recipients with an implantable cardioverter defibrillator due to life-threatening arrhythmias : a 5 year follow-up

   Författare :Inger Flemme; Linköpings universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; defibrillators implantable; ICD shocks; life-threatening arrhythmia; quality of life; satisfaction; uncertainty; MEDICINE; MEDICIN;

   Sammanfattning : The general aim of this thesis was to describe self-reported health-related quality of life (HRQoL) in recipients with an implantable cardioverter defibrillator (ICD) due to life-threatening arrhythmias over a 5-year period. The design was prospective and longitudinal. LÄS MER

   Sammanfattning : We present a method for developing multi-device services which allows for the creation of services that are adapted to a wide range of devices. Users have a wide selection of electronic services at their disposal such as shopping, banking, gaming, and messaging. LÄS MER

7. 5. Properties and tests for some classes of life distributions

   Författare :Bengt Klefsjö; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Life distribution; survival function; exponential distribution; IFR; IFRA; NBUE; DMRL; HNBUE; shock model; total time on test transform; testing of exponentiality;

   Sammanfattning : A life distribution and its survival function F = 1 - F with finitemean y = /q F(x)dx are said to be HNBUE (HNWUE) if F(x)dx < (>)U exp(-t/y) for t > 0. The major part of this thesis deals with the classof HNBUE (HNWUE) life distributions. LÄS MER
