  1. 16. Sources, emissions, and occurrence of chlorinated paraffins in Stockholm, Sweden

    Författare :Ulrika E. Fridén; Urs Berger; Michael S. McLachlan; Jacob de Boer; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Chlorinated paraffins; CPs; polychlorinated n-alkanes; PCAs; Air; Dust; Analysis; Exposure; Emissions; Environmental chemistry; Miljökemi; Applied Environmental Science; tillämpad miljövetenskap;

    Sammanfattning : Chlorinated paraffins (CPs) are ubiquitous environmental contaminants. They fulfill all of the criteria (persistent, toxic, and subject to long-range transport) for persistent organic pollutants (POPs) according to the United Nations Economic Commission for Europe (UNECE).

  3. 17. Modeling the global fate and transport of perfluoroalkylated substances (PFAS)

    Författare :James M. Armitage; Ian T. Cousins; Michael S. McLachlan; David Ellis; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; perfluoroalkylated substances; global-scale; fate and transport; Environmental chemistry; Miljökemi; Applied Environmental Science; tillämpad miljövetenskap;

    Sammanfattning : Perfluoroalkylated substances (PFAS) are persistent contaminants that are widely distributed in the global environment. Despite the fact that these chemicals have been manufactured and used for over 50 years, there has been little scientific and regulatory interest until very recently. LÄS MER

  4. 18. Reconfiguring Conservation and Ontological Politics : An Ethnography of Campesinos and Scientists in the Andean Páramos

    Författare :Cesar Camilo Castillo Estupiñan; Steve Woolgar; Jonas Anshelm; Brit Ross Winthereik; Linköpings universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Conservation; Ontology; Ontological politics; Ethnography; Páramos; Campesinos; Scientific practices; Boundary-making; Space; Differences; Intervention;

    Sammanfattning : This thesis offers an empirical analysis that critically assesses and expands the concept of “ontological politics” as a tool for understanding environmental conservation practice. It takes the case of páramos conservation in Colombia, a high mountain ecosystem located above 2600 mts altitude. LÄS MER

  5. 19. Aspects of Wide-Area Damping Control Design using Dominant Path Synchrophasor Signals

    Författare :Yuwa Chompoobutrgool; Luigi Vanfretti; Glauco Nery Taranto; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; power system stability and control; inter-area oscillations; wide-area damping control; synchrophasor measurements; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : The presence of inter-area oscillations has long affected stability constraints, and therefore, limited the power transfer capacity of interconnected power systems. Adequate damping of these inter-area oscillations is, thus, necessary to secure system operation and ensure system reliability while increasing power transfers. LÄS MER

  7. 20. Antibiotic Resistance in Enterobacteriaceae Isolated from Wild Birds

    Författare :Jonas Bonnedahl; Björn Olsen; Martin Wierup; Uppsala universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : The presence and spread of clinically important antibiotic-resistant bacteria in reservoirs from natural environments are not well studied compared to the clinical environments. The overall aim of this project was to study the presence of clinically important antibiotic-resistant bacteria in a reservoir from natural environments. LÄS MER
