  1. 11. Resistance and recolonization of bryophyte assemblages following disturbances : - detecting patterns and exploring mechanisms

    Författare :Martin Schmalholz; Kristoffer Hylander; Jari Kouki; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Bryophytes; boreal forest; boulders; clear-cutting; disturbance; establishment; insect outbreaks; microtopography; recolonization; resistance; spatial heterogeneity; succession; wildfires; Biology; Biologi; Plant Ecology; växtekologi;

    Sammanfattning : Disturbances are ubiquitous features of most northern forest ecosystems. The subsequent response of plant assemblages on both short (resistance or not) and long term (recolonization or not) will depend on a number of factors operating at several spatial scales. LÄS MER

    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; High-voltage direct current HVDC ; hybrid alternate-common arm converter HACC ; hybrid converters; line-commutated converters LCCs ; modular multilevel converters MMCs ; thyristors; Hybrid alternate-common-arm converter HACC ; hybrid omvandlare; högspänd likströmsöverföring HVDC ; linjekommuterade omvandlare LCC ; modulära multinivåomvandlare MMC ; tyristorer; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : The line-commutated converter (LCC) and the voltage-source converter (VSC) are the two main converter technologies utilized in high-voltage direct current (HVDC) transmission applications. Depending on the application requirements, one technology might be more advantageous than the other. LÄS MER

  5. 14. Human innate lymphoid cell trafficking and function in vivo

    Författare :Arlisa Alisjahbana; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Human organs and tissues, such as the lung, are composed of various spatially distinct anatomical compartments. Each compartment represents a different tissue environment within the organ, performs specific functions and in turn promotes the development, migration, and function of specific cell types. LÄS MER

  7. 15. ”De gränslösa böckerna” : Allålderslitteratur i Sverige under 1960- och 1970-talen, med studier i Hans Alfredsons och Barbro Lindgrens tidiga författarskap
