  3. 2. Measurement and control of oxygen fugacity by means of gaseous oxygen buffers

    Författare :Sven Berglund; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Fundamental and practical aspects of oxygen buffering are reviewed, with particular reference to the gaseous oxygen buffer as a tool in elevated temperature oxide chemistry. An oxygen buffer capacity concept and a classification scheme for oxygen buffers are proposed; their application is demonstrated. LÄS MER

  4. 3. The significance of mitochondrial respiratory function in regulating oxygen uptake and performance in humans

    Författare :Daniele A. Cardinale; Filip J Larsen; David Bishop; Gymnastik- och idrottshögskolan; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; mitochondria; OXPHOS; p50mito; mitochondrial oxygen affinity; oxygen extraction; sex difference; hyperoxia; training; muscle metabolism; performance; HIIT; Medicin Teknik; Medicine Technology;

    Sammanfattning : The mitochondrion is one of the most fascinating organelles of our cells which has kept and keeps researchers busy in studying its origin, the complex morphology, the numerous functions, the rapid adaptations to a variety of stimuli and its role in health and disease. Exercise challenges cellular homeostasis and skeletal muscle mitochondria greatly adapt to repeated bouts of exercise by increasing mitochondrial respiratory function and content to match energy requirements and to better sustain future perturbations induced by muscle contractions.

  5. 4. New perspectives in mesospheric wave dynamics and oxygen photochemistry

    Författare :Anqi Li; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; oxygen airglow; mesospheric ozone.; gravity wave; Satellite limb observation;

    Sammanfattning : The mesosphere is the region of the atmosphere between 50km to 100km, where both dynamical and photochemical aspects play important roles for the thermal balance. This thesis focuses on the following three areas for mesospheric studies: wave dynamics, oxygen photochemistry and retrieval using the optimal estimation method. LÄS MER

  7. 5. The RDGT - Integration of Micromechanics and Electronics by Plasma Assisted Wafer Bonding

    Författare :Anke Sanz-Velasco; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; bonding; displacement measurement; oxygen plasma; low temperature wafer bonding; capacitive detection; high resolution; CMOS compatibility; MOSFET; low impedance sensing; resonant gate transistor;

    Sammanfattning : A high-resolution capacitive sensing technique is presented in this thesis: the Resonant Double Gate Transistor (RDGT). The major advantage of the RDGT compared to "pure" capacitive sensing techniques is its low output impedance because of the direct capacitance to current conversion of the transistor. LÄS MER
