  1. 21. PBDEs in the Environment : Time trends, bioaccumulation and the identification of their successor, decabromodiphenyl ethane

    Författare :Amelie Kierkegaard; Lillemor Asplund; Cynthia de Wit; Michael McLachlan; Jacob de Boer; Stockholms universitet; []
    Nyckelord :PBDE; BDE209; dietary absorption; metabolism; debromination; bioaccumulation; decabromodiphenyl ethane; decabromodiphenyl ether; Applied Environmental Science; tillämpad miljövetenskap;

    Sammanfattning : Polybrominated diphenyl ethers (PBDEs) are important chemical flame retardants, but also environmental pollutants. Their bromine substitution lends them a different bioaccumulation behaviour than the better studied organochlorines.The contamination of a Swedish lake with lower brominated BDEs was assessed by a retrospective study of pike.

  3. 22. Participles in Time. The Development of the Perfect Tense in Swedish

    Författare :Ida Larsson; Göteborgs universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; Scandinavian syntax; Swedish; language change; tense; aspect; perfect; participle; supine; resultative; unaccusativity; auxiliary selection;

    Sammanfattning : This thesis concerns the syntactic-semantic development of the perfect tense from a construction with possessive HAVE and a tenseless participial complement. Both participles and auxiliary are assumed to have internal syntactic structure, and the different perfect-type constructions can thus be related synchronically and diachronically to each other.

  4. 23. Optimized Pacing Strategies in Cross-Country Skiing and Time-Trial Road Cycling

    Författare :David Sundström; Mats Tinnsten; Peter Carlsson; John Rasmussen; Mittuniversitetet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Optimization; numerical simulation; equations of motion; MMA; cross-country skiing; cycling; Optimering; numerisk simulering; rörelseekvationer; MMA; längdskidåkning; cykling;

    Sammanfattning : This thesis is devoted to the analysis and optimization of pacing strategies in cross-country skiing and time-trial road cycling. In locomotive sports, it is well known that variable pacing strategies using changes in the distribution of power output are beneficial when external forces vary along the way. LÄS MER

  5. 24. Effects of Farming Practice on Pollinators and Pollination across Space and Time

    Författare :Georg Andersson; Biodiversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Several studies have found that organic farms support higher biodiversity, but results vary between studies such that some also show no or even negative effects. There can be many reasons why studies comparing organic and conventional farming show conflicting results. LÄS MER

  7. 25. On Distributed Control-by-Wire Systems for Critical Applications

    Författare :Roger Johansson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; time-triggered communication; fault-tolerance; distributed systems; dependable systems; inherent redundancy; control-by-wire;

    Sammanfattning : The implementation of closed loop control systems is an important field for the exploitation of embedded real-time computer systems. One can find a particularly interesting class of closed loop control applications within vehicle dynamics control. LÄS MER
