  1. 11. Logistics Alliances and Structural Change

    Författare :Dan Andersson; Linköpings universitet; []
    Nyckelord :SOCIAL SCIENCES; SAMHÄLLSVETENSKAP;

    Sammanfattning : The overall purpose of this study is to contribute to a better understanding of why and in what way shippers outsource logistics operations into partnerships with logistics service providers. These relationships are called "operational alliances in logistics" (OALs). LÄS MER

  3. 12. Hazardous substances in wastewater management

    Författare :Helena Palmquist; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; VA-teknik; Urban Water Engineering;

    Sammanfattning : The extensive use of materials and substances in society causes diffuse source emissions that lead to uncontrolled spreading of hazardous substances, largely channelled via wastewater systems, to the surrounding nature. Complex mixtures of substances appear in wastewater as a result of use, wear, and corrosion of goods (e.g. LÄS MER

  4. 13. Speciation genetics of recently diverged species

    Författare :Venkat Talla; Niclas Backström; Nicola Nadeau; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Speciation; Leptidea; Lepidoptera; chiffchaff; Cryptic species; genome-scan; Diapause; Biology with specialization in Evolutionary Genetics; Biologi med inriktning mot evolutionär genetik;

    Sammanfattning : Species differentiation can be a consequence of evolutionary forces including natural selection and random genetic drift. Patterns of genomic differentiation vary across the tree of life. This variation seems to be dependent on, for example, differences in genomic architecture and molecular mechanisms. LÄS MER
