  1. 6. Mobility and Routing in a Delay-tolerant Network of Unmanned Aerial Vehicles

    Författare :Erik Kuiper; Simin Nadjm-Tehrani; Roberto Baldoni; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; mobility models; routing; ad hoc networks; delay-tolerant networks; Computer science; Datalogi;

    Sammanfattning : Technology has reached a point where it has become feasible to develop unmanned aerial vehicles (UAVs), that is aircraft without a human pilot on board. Given that future UAVs can be autonomous and cheap, applications of swarming UAVs are possible. LÄS MER

  3. 7. Regulation of bacterial adaptive behavior by the second messenger cyclic-di-GMP and host components

    Författare :Soazig Le Guyon; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : To optimize survival and growth, bacteria have evolved adaptive behaviors that respond to relevant environmental signals. A switch from the motile to the sessile lifestyle is probably the most ancient behavioral transition of microorganisms. LÄS MER

  4. 8. Wild Poethics - Exploring relational and embodied practices in urban-making

    Författare :Anna Maria Orrù; Chalmers tekniska högskola; []
    Nyckelord :HUMANIORA; HUMANITIES; HUMANIORA; HUMANITIES; HUMANIORA; HUMANITIES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; HUMANIORA; HUMANITIES; choreography; urban-making; naturecultures; critical spatial feminist practice; imagination; embodied methodology; poethics; affective atmospheres; relational assemblages; artistic research;

    Sammanfattning : Nature is not something separated from the city. With this in mind, this research emerges from the act of urban gardening, staging space for naturecultures that reinforce a direct relation to an urban nature. LÄS MER

  5. 9. Seasonal flight patterns of the Spruce bark beetle (Ips typographus) in Sweden : phenology, voltinism and development

    Författare :Petter Öhrn; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : The major bark beetle threat to Norway spruce (Picea abies (L.) Karst.) in Eurasia is the spruce bark beetle Ips typographus. Beetles cause damage after population build-up in defenseless trees. LÄS MER

  7. 10. Diverse cyclic dinucleotide signals regulate Escherichia coli lifestyle transition

    Författare :Fengyang Li; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Bacteria have the ability to change their lifestyle to adapt to various environmental conditions. Cyclic dinucleotides (cDNs) are ubiquitous second messengers that can regulate fundamental lifestyle switches, such as motility versus sessility and acute versus chronic virulence, in bacteria.
