  1. 1. Gas Production in Distant Comets

    Författare :Marcus Gunnarsson; F Peter Schloerb; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Astronomy; Comets; Radio Astronomy; Molecular Spectroscopy; Coma Models; Astronomi; Astronomy and astrophysics; Astronomi och astrofysik; astronomi; Astronomy;

    Sammanfattning : Molecular spectroscopy at radio wavelengths is a tool well suited for studying the composition and outgassing kinematics of cometary comae. This is particularly true for distant comets, i.e. comets at heliocentric distances greater than a few AU, where the excitation of molecules is inefficient other than for rotational energy levels.

  3. 2. The risk of dying : predicting trauma mortality in urban Indian hospitals

    Författare :Martin Gerdin; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Introduction: With increased urbanisation and motorisation, trauma is emerging as one of the top threats to population health globally. Each year almost five million people die as a result of trauma, more than the total number of deaths from HIV/AIDS, tuberculosis, malaria, and maternal conditions combined. LÄS MER

  4. 3. Plasma and Dust around Icy Moon Enceladus and Comet 67P/Churyumov-Gerasimenko

    Författare :Ilka. A. D. Engelhardt; Anders Eriksson; Ingrid Mann; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fysik med inriktning mot rymd- och plasmafysik; Physics with specialization in Space and Plasma Physics;

    Sammanfattning : Saturn's moon Enceladus and comet 67P/Churyumov-Gerasimenko both are examples of icy solar system objects from which gas and dust flow into space. At both bodies, the gas becomes partly ionized and the dust grains get charged. LÄS MER

  5. 4. Brain injury biomechanics in closed-head impact : studies on injury epidemiology, tolerance criteria, biomechanics and traffic injury prevention

    Författare :David Viano; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Closed-head impact; brain injury; biomechanics; injury mechanisms; tolerance criteria; epidemiology; and primary prevention.;

    Sammanfattning : Permanent disability from traumatic brain injury is a devastating consequence of traffic crashes. Injury prevention is a fruitful approach to reduce the incidence and severity of disabling brain injury. LÄS MER

  7. 5. Pathophysiological characterization of traumatic brain injury using novel analytical methods

    Författare :Cecilia Åkerlund; David Nelson; Anders Holst; Ari Ercole; Niklas Marklund; KTH; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Traumatic brain injury; Intracranial pressure; clustering; Medicinsk teknologi; Medical Technology;

    Sammanfattning : Severity of traumatic brain injury is usually classified by Glasgow coma scale (GCS) as “mild”, "moderate" or "severe’, which does not capture the heterogeneity of the disease. According to current guidelines, intracranial pressure (ICP) should not exceed 22 mmHg, with no further recommendations concerning individualization or tolerable duration of intracranial hypertension.
