  1. 26. Molecular mechanisms involved in prokaryotic cycling of labile dissolved organic matter in the sea

    Författare :Benjamin Pontiller; Jarone Pinhassi; Daniel Lundin; Catherine Legrand; Martin F. Polz; Linnéuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Bacteria and archaea; labile dissolved organic matter; metatranscriptomics; monomers; polymers; carbohydrate-active enzymes CAZymes ; peptidases; membrane transporters; Natural Science; Naturvetenskap; Akvatisk ekologi; Aquatic Ecology; Mikrobiologi; Microbiology;

    Sammanfattning : Roughly half of the global primary production originates from microscopic phytoplankton in marine ecosystems, converting carbon dioxide into organic matter. This organic matter pool consists of a myriad of compounds that fuel heterotrophic bacterioplankton. LÄS MER

  3. 27. Analysis and Synthesis of Heterogeneous Real-Time Systems

    Författare :Jakob Axelsson; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : During the development of a real-time system the main goal is to find an implementation that satisfies the specified timing constraints. Often, it is most cost-effective to use a heterogeneous solution based on a mixture of different microprocessors and application-specific integrated circuits. LÄS MER

  4. 28. Functional Programming for Securing Cloud and Embedded Environments

    Författare :Abhiroop Sarkar; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; trusted execution environment; real time; functional programming; runtime; information flow control; microcontrollers; functional reactive programming;

    Sammanfattning : The ubiquity of digital systems across all aspects of modern society, while beneficial, has simultaneously exposed a lucrative attack surface for potential adversaries and attackers. Consequently, securing digital systems becomes of critical importance. LÄS MER

  5. 29. Carbon allocation in aspen trees

    Författare :Sonja Viljamaa; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Trees allocate assimilated carbon between growth and storage. In this PhD thesis, Iinvestigated the regulation of carbon allocation during tree growth both attranscriptional as well as whole-tree level, and with a focus on wood formation. LÄS MER

  7. 30. Body Size Evolution in Butterflies

    Författare :David Berger; Karl Gotthard; Wolf Blanckenhorn; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Body size evolution; age- and size at maturity; life history theory; fecundity; predation risk; juvenile growth rate; Lepidoptera; Biology; Biologi; zoologisk ekologi; Animal Ecology;

    Sammanfattning : Life history research deals with the scheme of resource partitioning to a wide spectra of processes and the trade-offs shaping these events. One of the most fundamental life history trade-offs is the one of at which age- and size an organism should start to reproduce; reaching a large size at maturity is often advantageous in terms of high adult survival and reproductive potential, while to attain a larger size the organisms must prolong juvenile development which is assumed costly in terms of mortality.
