  1. 1. The Littorina transgression in southeastern Sweden and its relation to mid-Holocene climate variability

    Författare :Shiyong Yu; Kvartärgeologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; marklära; kartografi; Fysisk geografi; geomorfologi; climatology; cartography; pedology; geomorphology; Physical geography; tidal action; solar forcing; global meltwater pulse; North Atlantic storminess; climate changes; shoreline displacements; sea-level fluctuations; Littorina transgression; Baltic Sea; klimatologi;

    Sammanfattning : Lateglacial and Holocene shoreline displacement along the Baltic coast resulted from both the isostatic land uplift and the ice-volume-equivalent sea-level rise. Relative changes of these two components led to alternating contact/isolation of the Baltic Basin with the North Sea during the Holocene. LÄS MER

  3. 2. Chloride Transport in Concrete under the Frost Action – An Experimental Study

    Författare :Bo Li; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; temperature; chloride; concrete; freeze-thaw cycles; water uptake; chloride profile; frost action; transport;

    Sammanfattning : Frost-induced ingress of chloride in concrete is one of the typical transport phenomena of aggressive substances when structures expose to severe environments such as marine tidal zone and de-icing highway in winter seasons. It is well known that Chloride ingress in concrete causes the reinforcement corrosion. LÄS MER

  4. 3. Compositional variability of settling organic particles in non-tidal coastal and shelf enviroments

    Författare :Mona Petersson; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Earth sciences; vertical flux; particulate matter; amino acids; Skagerrak; Limfjorden; Geovetenskap; Earth sciences; Geovetenskap; naturgeografi; Physical Geography;

    Sammanfattning : The coupling between the composition of settling organic particles and near-bed dynamics was studied in non-tidal coastal and shelf environments. Field investigations were made in Skagerrak and Limfjorden between 1990 and 1995. LÄS MER

  5. 4. Opioids and regulation of breathing

    Författare :Åsa Österlund Modalen; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Sameridine; partial - opioid agonist; local anesthetic; morphine; ventilation; respiratory depression; hypercarbia; hypoxia; frakefamide; peripheral -opioid agonist;

    Sammanfattning : A most important challenge even in modern medicine is effective treatment of pain. Respiratory depression is the most feared side effect of analgesic treatment in the clinical situation. LÄS MER

  7. 5. Characterisation of aerosol delivery devices and their influence on deposition in humans and animals

    Författare :Ola Nerbrink; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : One way of administrating pharmaceutical drugs in the development phase and in the clinical situation is by inhalation. It is essential to ensure an accurate delivered dose, as the prediction of the effect and side effects of the drug action is dependent on a precise estimation of the given dose. LÄS MER
