  1. 6. Ethanol-mediated effects on astroglial cells in primary culture. With a focus on acute changes in intracellular Ca2+, cell volume, actin filaments, and gap junction coupling

    Author : Louise Adermark; Göteborgs universitet.; Gothenburg University.; [2003]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; astrocyte; BaCl2; cell swelling; fura-2; furosemide; ouabain; scrape loading; volume estimation;

    Abstract : The astroglial cells are abundant in the central nervous system (CNS), where they control and regulate the homeostasis of the extracellular milieu. A change in astroglial cell volume, mediated through activation of neuroactive substances or changes in osmolarity, leads to changes in the size and geometry of the extracellular space volume, which could affect the diffusion and concentration of neuroactive substances.

  2. 7. Monitoring alveolar recruitment in the critically ill - Patient studies using electric impedance tomography and volume-dependent compliance

    Author : Karin Lowhagen; Göteborgs universitet.; Gothenburg University.; [2010]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; ALI; ARDS; compliance; end-expiratory lung volume; EELV; EIT; electric impedance tomography; lung recruitment; morbid obesity; PEEP; recruitment manoeuvre; regional ventilation; volume-dependent compliance;

    Abstract : Background: Acute lung injury (ALI) and acute respiratory distress syndrome (ARDS) are associated with a high mortality rate and poor long term outcome in terms of quality of life, for those who survive. Similarly, patients with morbid obesity are at risk for respiratory complications when subjected to anaesthesia and surgery. READ MORE

  3. 8. Recommendation changes in walls of glass perceived roles and relative importance of direct contacts

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Jeaneth Johansson; [2004]
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Accounting and Control; Redovisning och styrning;

    Abstract : The equities recommendations of financial analysts to investors are often seen as mysterious created through skilled handcraft difficult to understand for the uninitiated. The core issue in this study is connected to the stock market functioning and the ability of analysts to disclose reliable and similar information to investors. READ MORE

  4. 9. Studies of changes in volume in right ventricle with electrical bio impedance

    University dissertation from Stockholm : Karolinska Institutet, Dept of Laboratory Medicine

    Author : Karin Järverud; Karolinska Institutet.; Karolinska Institutet.; [2002]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; intracardiac impedance;

    Abstract : In intracardiac impedance, electrical bio-impedance is measured inside the heart. This signal is known to reflect the volume of blood passing in and out of the ventricles. In transthoracic impedance the measurement current and voltage sensing is connected on the subject’s chest. READ MORE

  5. 10. On the Volume Changes during the Solidification of Cast Irons and Peritectic Steels

    University dissertation from Stockholm : Kungliga Tekniska högskolan

    Author : Abel Tadesse; Michael Vynnycky; Hasse Fredriksson; Jacques Lacaze; [2017]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Volume changes; Solidification; Peritectic steel; Micro- and Macro-shrinkage; LVDT; GCI; NCI; Hypo- and Hypereutectic; Austenite; DTA; Dilatometry; BSE; Nuclei; Flake graphite; SDAS; Eutectic cells; Undercooled graphite; Simulation; Cooling rate; Microsegregation; austenite; Metastable region; δ-ferrite; Stable phase diagram; Grain refinement; Strain.; Materials Science and Engineering; Teknisk materialvetenskap;

    Abstract : This thesis work deals with the volume changes during the solidification of cast irons and peritectic steels. The volume changes in casting metals are related to the expansion and/or contraction of the molten metal during solidification. Often, different types of shrinkage, namely macro- and micro-shrinkage, affect the casting quality. READ MORE
