  1. 1. Initiation of ventilation, surfactant treatment, and lung function after preterm birth

    Författare :Lars Björklund; Lund Pediatrik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Respiration; Artificial; Pediatrics; Pediatri; Respiratory Function Tests; Pulmonary Surfactants; Newborn; Respiratory Distress Syndrome; Infant; Premature; Animals;

    Sammanfattning : The thesis investigates lung function and the effects of rescue surfactant treatment in mechanically ventilated preterm human infants with respiratory distress syndrome (RDS), and the effects of ventilation at birth on the response to surfactant supplementation in preterm lambs. To assess lung function, the author recorded static pressure-volume (P-V) curves during passive deflation from total lung capacity (TLC) to ambient pressure and measured end-expiratory lung volume (FRC) during mechanical ventilation by tracer gas washout.

  4. 3. Water splitting in natural and artificial photosynthetic systems

    Författare :Sergey Koroidov; Johannes Messinger; Richard J. Debus; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Water splitting; photosystem II; artificial catalyst; MIMS; inorganic carbon;

    Sammanfattning : Photosynthesis is the unique biological process that converts carbon dioxide into organic compounds, for example sugars, using the energy of sunlight. Thereby solar energy is converted into chemical energy. Nearly all life depends on this reaction, either directly, or indirectly as the ultimate source of their food. LÄS MER

  5. 4. Artificial Intelligence for Non-Contact-Based Driver Health Monitoring

    Författare :Hamidur Rahman; Mobyen Uddin Ahmed; Shahina Begum; Peter Funk; Hasan Fleyeh; Mälardalens högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Driver Monitoring; Artificial Intelligence; Machine Learning; Deep Learning; Computer Science; datavetenskap;

    Sammanfattning : In clinical situations, a patient’s physical state is often monitored by sensors attached to the patient, and medical staff are alerted if the patient’s status changes in an undesirable or life-threatening direction. However, in unsupervised situations, such as when driving a vehicle, connecting sensors to the driver is often troublesome and wired sensors may not produce sufficient quality due to factors such as movement and electrical disturbance.

  7. 5. Regional Lung Mechanics and Influence of an Active Diaphragm in Experimental Lung Injury

    Författare :Mariangela Pellegrini; Anders Sune Larsson; Göran Hedenstierna; Michael Quintel; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; acute respiratory distress syndrome; artificial respiration; diaphragm; pulmonary atelectasis; lung imaging; respiratory system; animal model; Fysiologi; Physiology; Anestesiologi och intensivvård; Anaesthesiology and Intensive Care;

    Sammanfattning : Despite being an essential life-support strategy in severe respiratory failure, mechanical ventilation can, if not optimally set and monitored, lead to injury of the lung parenchyma and diaphragm. These conditions are called ventilator-induced lung injury and ventilator-induced diaphragmatic dysfunction (VIDD), respectively. LÄS MER
