  1. 11. Francisella tularensis: persistence, dissemination and source attribution : a theoretical and computational approach

    Författare :Chinmay Kumar Dwibedi; Anders Johansson; Pär Larsson; Markus Antwerpen; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Francisella; genomics; evolution; microbial forensics; dispersal; persistence; mikrobiologi; Microbiology;

    Sammanfattning : The bacterium Francisella tularensis causing tularemia in humans and other mammals displays little genetic diversity among genomes across temporal and spatial scales. F. tularensis infects humans with an extremely low infectious dose and causes natural seasonal tularemia outbreaks. LÄS MER

  3. 12. Secondary Metabolites from Bolivian Plants- Isolation and Characterization

    Författare :Marcelo Davila; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Phytochemistry; Natural Prodcuts;

    Sammanfattning : Nature has been recognized as a rich source of potentially useful chemicals. Throughout the years, phytochemical studies have led to the discovery of an enormous number of natural products, their chemical diversity is unique and many of them possess various biological activities.

  4. 13. Enhanced Biological Phosphorus Removal - Carbon Sources, Nitrate as Electron Acceptor, and Characterisation of the Sludge Community

    Författare :Magnus Christensson; Bioteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; activated sludge; nitrate; carbon source; PAO; polyphosphate accumulating organisms; enhanced biological phosphorus removal; EBPR; characterisation; Biotechnology; Bioteknik;

    Sammanfattning : Enhanced biological phosphorus removal (EBPR) was studied in laboratory scale experiments as well as in a full scale EBPR process. The studies were focused on carbon source transformations, the use of nitrate as an electron acceptor and characterisation of the microflora. LÄS MER

  5. 14. Isolation, Characterization and Risk Analysis of Organic Micropollutants in Water

    Författare :Bo Wigilius; Linköpings universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; INTERDISCIPLINARY RESEARCH AREAS; TVÄRVETENSKAPLIGA FORSKNINGSOMRÅDEN;

    Sammanfattning : The work in this thesis primarily aimed at studying and further developing methods for the isolation, fractionation and characterization of organic compounds in water.Suitable concentration methods are a prerequisite for the characterization and risk analysis of such compounds.

  7. 15. Health-related aerosol particle studies, respiratory tract deposition and indoor source identification

    Författare :Jakob Löndahl; Kärnfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; aerosol particle; health; ultrafine particles; nanoparticle; deposition; respiratory tract; Fysicumarkivet A:000;

    Sammanfattning : Aerosol particles have, since Classical Antiquity, been linked to adverse effects on human health. It is estimated that the particles in urban air pollution causes 100 000 deaths in Europe each year, whereof 5 000 in Sweden. LÄS MER
