  1. 1. Forming wide-orbit planets via pebble accretion

    Master-uppsats, Lunds universitet/Astrofysik; Lunds universitet/Fysiska institutionen

    Författare :Nerea Gurrutxaga; [2023]
    Nyckelord :Planet Formation; Pebble Accretion; Protoplanetary Disk; Wide-Orbit Planet; Physics and Astronomy;

    Sammanfattning : The possibility that detected substructures in protoplanetary disks, such as gaps, rings and cavities, are created by distant protoplanets has prompted an inquiry into the mechanism responsible for their formation. These wide-orbit young bodies are likely to form relatively rapidly in the outer regions of circumstellar disks. LÄS MER

  3. 2. Cotula coronopifolia : invasive or just another alien species?

    Master-uppsats, SLU/Dept. of Ecology

    Författare :Lina Tomasson; [2020]
    Nyckelord :Cotula coronopifolia; dispersal mechanism; invasive species;

    Sammanfattning : It is known that alien species can become invasive in a new environment and in new geographic areas. The recent and rapid expansion of Cotula coronopifolia (cotula)on the island of Öland in Sweden has raised questions about its potential invasiveness. LÄS MER

  4. 3. Beyond a Roof and Walls: Gaps and Challenges in Providing Adequate Housing for Refugees in Malmö

    Författare :Asha Manori Sri Nissanka; [2020]
    Nyckelord :Refugees; Settlement Act; Malmö; Housing market; Adequate housing;

    Sammanfattning : This study attempts to analyse urban housing issues and their effects on providing adequate housing for refugees, using Malmö as a case study. The content analysis adopted here uses a combination of semi-structured interviews with relevant government officers, and reports published by government agencies and international institutions as sources of information.

  5. 4. IPM-strategier för kålmjöllusen Aleyrodes proletella : en ny skadegörare på tröskeln till Sverige

    Kandidat-uppsats, SLU/Dept. of Biosystems and Technology (from 130101)

    Författare :Johanna Weimers; [2016]
    Nyckelord :kålmjöllus; Aleyrodes proletella; invasiva skadegörare; Sverige; IPM; integrerat växtskydd; biologisk bekämpning; naturliga fiender;

    Sammanfattning : Kålmjöllusen, Aleyrodes proletella är en allvarlig skadegörare i kålodling, främst brysselkål och grönkål, i Europa. Likt andra vita flygare sitter lössens nymfstadium på undersidan av bladen och suger växtsaft och kontaminerar dem med skalrester och honungsdagg där sotdaggssvampar kan tillväxa. LÄS MER

  7. 5. Spridningsmönster och potentiella spridningsytor hos invasionsarten stor bockrot (Pimpinella major) i Tullgarns naturvårdsområde : ett framtida problem för områdets diversitet?

    Kandidat-uppsats, Akademin för hållbar samhälls- och teknikutveckling

    Författare :Henrik Paulsson; [2009]
    Nyckelord :invasionsart;

    Sammanfattning : An organism that is transferred from one place to another, causing major problems to the native species is termed invasive. Its natural dispersal across barriers may have been prevented but as man has turned able to rapidly travel all over the world organisms are brought to sites where they were never before observed.
