  2. 1. Haemodynamic management in liver surgery

    Author : Lena Sand; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; liver resection; nitroglycerine; central venous pressure; vasopressin; patient position; PEEP;

    Abstract : Background: Liver resection surgery is a potentially curative treatment for liver tumours. The liver is a highly vascular organ, and substantial intra-operative blood loss is common. Increased blood loss negatively impacts both postoperative outcome and long-term survival. READ MORE

  4. 2. Matrix Suction in Silt and Sand Slopes. Significance and Practical Use in Stability Analysis

    Author : Anna-Lena Öberg; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Conventional stability analysis in unsaturated silt and sand slopes often results in unrealistically low factors of safety. The purpose of the study was to increase the knowledge and the understanding of the unsaturated zone and its matrix suction in order to facilitate more elaborate stability analyses of silt and sand slopes.

  5. 3. Morphological and Molecular Phylogenetic Studies in Neotropical Gentianaceae

    Author : Lena Struwe; Pamela S Soltis; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; systematisk botanik; Systematic Botany;

    Abstract : The Gentianaceae of the Neotropics are a diverse taxonomic group representing several evolutionary lineages. The phylogenetic relationships of neotropical gentians are discussed based on cladistic analyses of morphological, trnL intron, and ITS 1 sequence data. READ MORE

  6. 4. Volatile organic compounds from microorganisms : identification and health effects

    Author : Anna-Sara Claeson; Anna-Lena Sunesson; Jan-Olof Levin; Steven Nordin; Bengt Järvholm; Charles Weschler; Umeå universitet; []
    Keywords : microorganisms; building materials; VOCs; MVOCs; amines; LC-MS MS; exposure; perceived air quality; Occupational and Environmental Medicine; arbets- och miljömedicin;

    Abstract : Damp building materials are subjected to degradation processes due to moisture and also microbial growth, with both of these giving rise to emissions of volatile organic compounds (VOCs) that may contribute to indoor air health problems. The overall aim of this thesis was to investigate emissions of reactive and non-reactive VOCs from damp building materials and from the microorganisms growing on them, and also to investigate the possible health impact of these compounds.
