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

    Författare :Karin Lowhagen; Göteborgs universitet; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  3. 17. Temperature dependent mechanical properties of as-cast steels : Experimental and theoretical studies

    Författare :Zhihua Dong; Levente Vitos; Imre Bakonyi; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : The temperature-dependent mechanical properties of steels are important to avoid processing defects, to understand and to improve the high-temperature performance. At the same time, having access to thermal properties gives us opportunity to assess the first-principles theoretical predictions at elevated temperatures. LÄS MER

  4. 18. Spin-dependent recombination in Ga(In)NAs alloys

    Författare :Yuttapoom Puttisong; Weimin Chen; Irina Buyanova; Qingxiang Zhao; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : The abilities to control and manipulate electron spin, especially in semiconductors, lead to many interesting proposals for spin-functional devices in future spintronics and quantum information technology. A key requirement for the success of these proposals is that the spin functionality should be operational at room temperature (RT), which remains as a great challenge. LÄS MER

  5. 19. Heparan sulfate dependent cell signaling and associated pathophysiology : Implications in tumorigenesis and embryogenesis

    Författare :Tahira Batool; Jin-Ping Li; Aristidis Moustakas; Liliana Schaefer; Ingvar Ferby; Michael Welsh; Anders Malmström; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Heparanase; Glucuronyl-C5 epimerase; Heparan Sulfate; Heparin; Lung Cancer; Cancer cell Singling; TGF-Beta; BMP; VEGF; Notch Signaling; Tumor growth; Metastasis; embryonic development; Medical Biochemistry; Medicinsk biokemi;

    Sammanfattning : Heparan sulfate proteoglycans (HSPGs) consist of a protein core to which several linear, negatively charged heparan sulfate (HS) chains are covalently attached. HSPGs are expressed on the cell surface and in the extra-cellular matrix (ECM) where they have diverse biological functions, for example co-receptor functions. LÄS MER

  7. 20. Socially dependent avoidance learning : mechanisms of adaptive behavior

    Författare :Björn Lindström; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Many aspects of human social behavior are likely to be shaped by punishment, threats of punishment, and avoidance of punishment. However, surprisingly little is known about the psychological mechanisms underpinning these influences. LÄS MER
