  1. 11. Bioprocessing, Structure and Material Properties of Arabinoxylans

    Författare :Anders Höije; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; moisture content; biorefinery; Arabinoxylan; mechanical properties; chemical structure; isolation; film formation; oxygen permeability; enzymatic treatment;

    Sammanfattning : This work has focused on using agriculture residues as raw material for new polymeric materials. Arabinoxylans have been isolated from barley husks and endosperm fiber using alkali extraction, and the chemical composition and detailed structure have been determined. LÄS MER

  2. 12. Thin metal films on weakly-interacting substrates : Nanoscale growth dynamics, stress generation, and morphology manipulation

    Författare :Andreas Jamnig; Kostas Sarakinos; Gregory Abadias; Gregory Thompson; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Thin films; magnetron sputter-deposition; in situ and real-time characterization; early film growth stages; residual stress; manipulation of morphology; Couches minces; pulvérisation magnétron; caractérisation in situ en temps réel; premiers stades de croissance; contraintes résiduelles; manipulation de morphologie;

    Sammanfattning : Vapor-based growth of thin metal films with controlled morphology on weakly-interacting substrates (WIS), including oxides and van der Waals materials, is essential for the fabrication of multifunctional metal contacts in a wide array of optoelectronic devices. Achieving this entails a great challenge, since weak film/substrate interactions yield a pronounced and uncontrolled 3D morphology. LÄS MER

  3. 13. 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

  4. 14. Influence of tidal volume on pulmonary gas exchange during general anaesthesia

    Författare :Bruno Enekvist; Anestesiologi och intensivvård; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; anaesthesia; sevoflurane; cardiac output; functional residual capacity; pulmonary gas exchange;

    Sammanfattning : Background and objective: General anaesthesia impairs respiratory function. The present studies were performed to compare arterial concentration of sevoflurane, oxygen and carbon dioxide in normal and overweight patients ventilated with increased tidal volume (VT), or normal tidal volume with and without PEEP.

  5. 15. Lung volumes and lung mechanics in anesthetized children

    Författare :Adalbjörn Thorsteinsson; Anestesiologi och intensivvård; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; sulfur hexafluoride; Anaesthesiology; lung volumes; lung compliance; Anesthesia: pediatric; functional residual capacity; intensive care; Anestesiologi; ventilation inhomogeneity; intensivvård; airway closure;

    Sammanfattning : The thesis was intended to fill gaps in the knowledge regarding the normal development of lung volumes and lung mechanics in children, from young infancy to the mid-teens. In particular, data were previously lacking regarding pre-school children. The studies were done during anesthesia and muscle relaxation. LÄS MER
