2. 6. Endotracheal Suction a Reopened Problem

   Author : Birgitta Almgren; Marieann Högman; Mats Sjöquist; Anders Larsson; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Physiology; Mechanical; ventilation; endotracheal; suction; lung; volume; loss; gas; exchange; Fysiologi; Physiology; Fysiologi;

   Abstract : During mechanical ventilation, patients are connected to the ventilator by an endotracheal tube. The tube needs to be cleaned from mucus by suction, which can cause negative effects such as lung collapse, hypoxemia and desaturation. READ MORE

4. 7. Cellulose-based Conducting 3D and 2D Composites for Applications in Plant Science and Responsive Systems

   Author : Vasileios Oikonomou; Eleni Stavrinidou; Magnus Berggren; Anna Herland; Linköpings universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; polymers; cellulose; conjugated polymers; volume changes; plant growth substrates;

   Abstract : Polymers (Greek: poly=many, meros=part) are large molecules made up of many small parts (monomers) in a repetitive way, as a term was introduced for the first time (1833) by the Swedish chemist, Jöns Jakob Berzelius. By the combination of different monomers, the resulting polymer can exhibit various properties, such as biodegradability, photosensitivity and electrical conductivity. READ MORE

5. 8. 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; []
   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.

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

   Author : Karin Lowhagen; Göteborgs universitet; []
   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

7. 10. Recommendation changes in walls of glass : perceived roles and relative importance of direct contacts

   Author : Jeaneth Johansson; Luleå tekniska universitet; []
   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
