  1. 1. Peripheral airway function in asthma and cystic fibrosis. Measurements using inert gas washout methods

    University dissertation from Göteborg

    Author : Henrik Ljungberg; Göteborgs universitet.; Gothenburg University.; [2004]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; acinar; adults; airway hyperresponsiveness; asthma; children; conductive; functional residual capacity; gas trapping; inert gas washout; infants; peripheral airways; plethysmography; respiratory function tests; ventilation inhomogeneity;

    Abstract : It is increasingly recognised that asthma and cystic fibrosis (CF) frequently involves the peripheral airways. Characteristic features of abnormal peripheral airway function are uneven ventilation distribution and increased gas trapping. READ MORE

  2. 2. Molecular gas in the galaxy M83 Its distribution, kinematics, and relation to star formation

    University dissertation from Stockholm : Institutionen för astronomi

    Author : Andreas Andersson Lundgren; Stockholms universitet.; [2004]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Molecular gas; Galaxies; Galaxies individual: M83; Star formation; Galactic dynamics; NATURAL SCIENCES Physics Astronomy and astrophysics; NATURVETENSKAP Fysik Astronomi och astrofysik;

    Abstract : The barred spiral galaxy M83 (NGC5236) has been observed in the 12CO J=1–0 and J=2–1 millimetre lines with the Swedish-ESO Submillimetre Telescope (SEST). The sizes of the CO maps are 100×100, and they cover the entire optical disk. The CO emission is strongly peaked toward the nucleus. READ MORE

  3. 3. Gas-Phase Protein Structure Under the Computational Microscope Hydration, Titration, and Temperature

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Erik Marklund; Uppsala universitet.; [2011]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Molecular dynamics; gas phase; proteins; micelles; proton transfer; Grothuss mechanism; kinetics; NATURAL SCIENCES Physics; NATURVETENSKAP Fysik; Physics with specialization in Biophysics; Fysik med inriktning mot biofysik;

    Abstract : Although the native environment of the vast majority of proteins is a complex aqueous solution, like the interior of a cell, many analysis methods for assessing chemical and physical properties of biomolecules require the sample to be aerosolized; that is, transferred to the gas-phase. An important example is electrospray-ionization mass spectrometry, which can provide a wide range of information about e. READ MORE

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

    University dissertation from Department of Anaesthesiology and Intensive Care, Lund

    Author : Bruno Enekvist; Lund University.; Lunds universitet.; [2011]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; anaesthesia; sevoflurane; cardiac output; functional residual capacity; pulmonary gas exchange;

    Abstract : 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. 5. Development of Laser-Induced Fluorescence for Precombustion Diagnostics in Spark-Ignition Engines

    University dissertation from Combustion Physics, Lund Institute of Technology

    Author : Hans Neij; Lund University.; Lunds universitet.; [1998]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; DME; fuel tracer; Laser-induced fluorescence; 3-pentanone; acetone; residual gas; dimethyl ether; water vapor; Fysicumarkivet A:1998:Neij; Fysik; Physics; ion current;

    Abstract : Motivated by a desire to understand and optimize combustion in spark-ignition (SI) engines, laser techniques have been developed for measurement of fuel and residual gas, respectively, in the precombustion mixture of an operating SI engine. The primary objective was to obtain two-dimensional, quantitative data in the vicinity of the spark gap at the time of ignition. READ MORE
