1. 21. Functional residual capacity – development of new monitoring techniques for critically ill patients

   Författare :Cecilia Olegård; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; FRC functional residual capacity EELV end-expiratory lung volume volume dependent compliance VDC acute respiratory failure recruitment manouvre PEEP;

   Sammanfattning : Functional residual capacity (FRC) and end-expiratory lung volume (EELV) are important parameters for respiratory monitoring in critically ill adult and paediatric patients. Until now we have lacked clinically useful methods to measure these lung volumes. LÄS MER

3. 22. Single cell carbon and nitrogen dynamics in chain forming diatoms, including their resting stage

   Författare :Rickard Stenow; Göteborgs universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Diatoms; Resting stages; N cycling; Chain formation; Secondary ion mass spectrometry SIMS ;

   Sammanfattning : The oceans are a fundamental part of all life on earth, accounting for more than half of Earth’s oxygen production. The ocean is also key to long term carbon dioxide sequestration. Diatoms are a group of phytoplankton differentiated by their silica shell/frustule and account for ~20% of global primary production.

4. 23. Optimizing Enzyme Immobilization in Mesoporous Silica - A Spectroscopic Study of the Dynamics and Spatial Distribution of the Confined Enzymes

   Författare :Pegah Sadat Nabavi Zadeh; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fluorescence spectroscopy; dynamics; mesoporous silica; Immunogold staining; Transmission electron microscopy; anisotropy; microviscosity; real-time monitoring; Cy5.; Förster resonance energy transfer; Enzyme immobilization; Cy3;

   Sammanfattning : Enzymes as biological catalysts are immobilized in porous materials to improve the enzyme activity and simplify their purification from the reaction media in biocatalytic applications. Mesoporous silica (MPS) particles are used as a promising support material for the immobilization of enzymes. LÄS MER

5. 24. On-line Monitoring Techniques for the Study of Yeast Physiology. Some Studies on the Yeasts Pichia stipitis and Saccharomyces cerevisiae

   Författare :Gunnar Lidén; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : On-line monitoring techniques have been used with the goal of optimizing fermentation processes involving the yeasts Saccharomyces cerevisiae (Baker's yeast) and Pichia stipitis (a xylose fermenting yeast), and a highly equipped fermentor system has been developed for these studies. The fed-batch growth of S. LÄS MER

7. 25. Physiological effects of apnoeic oxygenation using high-flow nasal oxygen

   Författare :Ida-Maria Forsberg; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : In anaesthetic practice, the inability to oxygenate and ventilate patients is a much-feared complication with risk for severe hypoxia-induced adverse outcomes. By administrating oxygen in the absence of spontaneous ventilation, apnoeic oxygenation may overcome these challenges by a prolonged time with sufficient oxygenation. LÄS MER
