  1. 21. Text Clustering Exploration : Swedish Text Representation and Clustering Results Unraveled

    Författare :Magnus Rosell; Viggo Kann; Tapio Salakoski; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Informatics; computer and systems science; Informatik; data- och systemvetenskap;

    Sammanfattning : Text clustering divides a set of texts into clusters (parts), so that texts within each cluster are similar in content. It may be used to uncover the structure and content of unknown text sets as well as to give new perspectives on familiar ones. LÄS MER

  3. 22. Acidification of Swedish forest soils : evaluation of data from the Swedish forest soil inventory

    Författare :Johan Iwald; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Acidification of forest soils in Sweden has negatively affected nutrient status and caused toxic effects on biota. The aim of this thesis was to investigate potential impacts of two drivers of acidification of forest soils in Sweden: (1) tree growth with subsequent harvest and (2) deposition of sulphur and nitrogen compounds.

  4. 23. Biomonitoring of epichlorohydrin and some related compounds

    Författare :Helena Hindsø Landin; Bo Jönsson; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biomarkers; DNA Adducts; Epichlorohydrin; Glycidol; Hemoglobin adducts.; Physical Biology; fysikalisk biologi;

    Sammanfattning : This thesis considers epichlorohydrin (ECH), an important industrial chemical, that has been shown to be a carcinogen in experimental animals. The aim of this work is to improve the scientific basis for risk estimation of ECH and to suggest a reliable biomonitoring method for exposure. LÄS MER

  5. 24. Bioactive Compounds from the Marine Sponge Geodia barretti : Characterization, Antifouling Activity and Molecular Targets

    Författare :Martin Sjögren; Lars Bohlin; Per Jonsson; Anna-Karin Borg-Karlsson; Uppsala universitet; []
    Nyckelord :Pharmacognosy; Geodia barretti; barettin; secondary metabolites; settling inhibition; Balanus improvisus; analogs; 5-HT; Farmakognosi;

    Sammanfattning : The marine sponge Geodia barretti produces a range of secondary metabolites. Two of these compounds were isolated and elucidated guided by their ability to inhibit settlement of cypris larvae of the barnacle Balanus improvisus. LÄS MER

  7. 25. On the Determination of Reactive Compounds in Aerosols

    Författare :Mårten Spanne; Ergonomi och aerosolteknologi; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Environmental technology; industrial hygiene; isocyanates; particles; sampling; aerosols; pollution control; Miljöteknik; kontroll av utsläpp;

    Sammanfattning : Many sources of airborne contaminants have always been present in various work environments. With the development of thermosetting plastic systems, the use of reactive chemical compounds was greatly increased and thus also the risk of exposure to reactive and potentially hazardous compounds.
