  1. 6. 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

  2. 7. On the Volume Changes during the Solidification of Cast Irons and Peritectic Steels

    University dissertation from Stockholm : Kungliga Tekniska högskolan

    Author : Abel Tadesse; KTH.; [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

  3. 8. ASPECTS OF FLUID THERAPY: An experimental study of the effects of systemic inflammation, microvascular permeability, blood pressure and plasma volume

    University dissertation from Department of Clinical Sciences, Lund University

    Author : Maris Dubniks; Lunds universitet.; Lund University.; [2008]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; sepsis; activated protein C; SIRS; albumin; blood pressure; colloids; plasma volume; hypervolaemia; hypovolaemia; microcirculation; noradrenalin; permeability; prostacyclin;

    Abstract : Adequate circulating blood volume is a prerequisite for circulatory stability. Fluid therapy aims at correcting hypovolaemia, and is an important part of the haemodynamic management of perioperative and critically ill patients. READ MORE

  4. 9. FRC in acute lung injury. Experimental and clinical studies

    University dissertation from Department of Clinical Sciences, Lund University

    Author : Christian Rylander; Göteborgs universitet.; Gothenburg University.; [2005]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Airway obstruction; Acute lung injury; Acute respiratory distress syndrome; Attenuation; Computed tomography; End-expiratory lung volume; Functional residual capacity; Gas dilution; Hounsfield unit; Lung volume; Oleic acid; Recruitment; Time constant;

    Abstract : Respiratory failure due to acute lung injury (ALI) of diffuse inflammatory origin is a major cause of respiratory failure treated in intensive care units. In ALI, FRC is reduced by various mechanisms associated with hypoxemia and consolidation of the lung. READ MORE

  5. 10. Volume Change Effects during Solidification of Alloys

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Bahman Korojy; KTH.; [2009]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TECHNOLOGY Materials science; TEKNIKVETENSKAP Teknisk materialvetenskap;

    Abstract : Volume change during solidification is an important concept in achieving of casting soundness. The solidification shrinkage can cause different defects in the ingot casting as well as the shape casting. The volume change due to phase transformation during solidification is the other concept which has to be studied. READ MORE
