  1. 1. Numerical Study on Acoustic Phenomena in Cavities for Aero-engine Applications

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Eglantin Gjoni; [2023]
    Nyckelord :;

    Sammanfattning : For about seventy years, noise generated by grazing flow past a cavity has been thoroughly studied. Yet, a coherent theory that describes such phenomena is missing. Lately, this phenomena started to be investigated in bleeding systems of aero-engines. LÄS MER

  3. 2. Käringtand, parasiter och emissioner från idisslare : en litteraturstudie om samodling med käringtand och effekter av kondenserade tanniner

    Kandidat-uppsats, SLU/Dept. of Crop Production Ecology

    Författare :Nic Johansson; [2023]
    Nyckelord :Käringtand; Lotus corniculatus; egenskaper; biologi; samodling; baljväxt; vall; kondenserade tanniner; CT; parasiter; metanutsläpp; tillväxt; etablering; ensilering; fodervärde;

    Sammanfattning : Käringtand (Lotus corniculatus L.) kommer ursprungligen från medelhavsområdet men förekommer idag i olika delar av världen. Historiskt har käringtand hävdat sig väl i torra klimat samt i mindre produktiva områden där baljväxter som blålusern (Medicago sativa L.) och rödklöver (Trifolium pratense L. LÄS MER

  4. 3. Effects of past fragmentation and habitat loss and current management methods on the changes in vascular plant communities. : An evaluation of extinction debt in semi-natural grasslands in Sweden

    Kandidat-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildning

    Författare :Adina Sennblad; [2021]
    Nyckelord :;

    Sammanfattning : Habitat loss and fragmentation are believed to be two of the main reasons for high extinction rates of species, resulting in decreased biodiversity. According to the island biogeography theory, the species richness in a patch, here a semi-natural grassland, is dependent on the landscape composition, and therefore changes in the landscape composition will result in changes in the species richness of the grassland.

  5. 4. Change in surface area of semi-natural grassland in the Osby municipality, Scania and potential consequences for plant diversity

    Kandidat-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Katharina Borgström-Lohde; [2021]
    Nyckelord :Land use change; Semi-natural grasslands; Biodiversity; Scania; Historical land use; Earth and Environmental Sciences;

    Sammanfattning : During the past, land use has changed and still is. It has been recognized that land use changes affect biodiversity all over the world. In Sweden semi-natural grasslands are a habitat with high biodiversity. The topic of this thesis is how land use change has affected the habitat of semi-natural grasslands in the area around Osby, Scania. LÄS MER

  7. 5. Declining abundance and shifting distribution for Antarctic krill, Euphausia superba, in the western Antarctic Peninsula

    Master-uppsats, Lunds universitet/Examensarbeten i biologi

    Författare :Kerstin Holmström; [2020]
    Nyckelord :Biology and Life Sciences;

    Sammanfattning : Antarctic krill, Euphausia superba, a polar ocean specialist, thrives in the Antarctic severe physical conditions. The krill life cycle consists of strategies that have enabled and supported the species’ dominance of the Antarctic Ocean. Sea Ice extent and duration creates condition that are crucial for survival of the Furcilia larvae. LÄS MER
