  1. 1. Simulation-based discrimination of Crab pulsar models with XL-Calibur

    University essay from KTH/Fysik

    Author : Dennis Åkerström; [2024]
    Keywords : Astroparticle Physics; Astrophysics; Detector Physics; Simulation; Theoretical Physics; Engineering Physics; Pulsar models; Crab pulsar; Astropartikelfysik; Astropartikelfysik; Detektorfysik; Simulering; Teoretisk Fysik; Teknisk Fysik; Pulsar modeller; Krabbpulsaren;

    Abstract : Polarisation of X-ray light is being investigated with polarimeters to extend the borders of what can be observed. Distant compact objects, such as pulsars, that are to small on the sky to be analysed with imaging can be investigated by analysing the polarisation of the emitted light. This can reveal physics previously hidden by their small nature. READ MORE

  3. 2. Sex-associated genomic variation in two ecotypes of Littorina saxatilis on the Swedish west coast

    University essay from Göteborgs universitet/Institutionen för marina vetenskaper

    Author : Amin Ghane; [2022-09-26]
    Keywords : Littorina saxatilis; Sex chromosomes; Sex determination systems; Sex-associated genomic region;

    Abstract : Sex, one of the most conspicuous characteristics of living organisms, has always been fascinating for biologists. The diversity of sex goes much beyond a simple distinction between males and females. Many organisms have more than two mating entities, and many species show some degree of hermaphroditism, at least in part of their life cycle. READ MORE

  4. 3. Fibers and Textiles Produced from Chitin and Chitosan : A Literature Study For Different Production Methods

    University essay from Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Keywords : chitin; chitosan; fibers; nanofibers; textiles; wound dressing; sutures; spinning;

    Abstract : Ökningen av världspopulationen har orsakat en ökad avfallsgenerering. Avfallet kan innehålla betydelsefulla ämnen, vilka kan användas som råvaror i många olika material och för olika ändamål. READ MORE

  5. 4. Can the native shore crabs (Carcinus maenas) become a barrier to the invasion of the round goby (Neogobius melanostomus) in Öresund, southern Baltic Sea?

    University essay from Lunds universitet/Examensarbeten i biologi

    Author : Nikolaos Papagiannopoulos; [2018]
    Keywords : Biology and Life Sciences;

    Abstract : The round goby (Neogobius melanostomus) is a non-indigenous species to the Baltic Sea that has drawn the attention of many researchers in the last decade due to its rapid spreading and its impact on the local fauna. With recent concerns about the dispersal of the round goby towards the North Sea, the aim of this study was to determine if the native shore crab could compete with the invaders and prevent their advance.

  6. 5. Causes of trends in abundance of mesopredators in the Kattegat Sea

    University essay from SLU/Dept. Of Aquatic Resources

    Author : Karla Rudnicki; [2018]
    Keywords : shore crab; atlantic cod; mesopredator; Vendelsöarna; temperature; Ringhals; nuclear power plant;

    Abstract : It has come to attention that there is a mesopredator release effect present in the Kattegat Sea (northern Europe, between Sweden and Denmark). The areas in focus here are Ringhals, a nuclear power plant zone, and Vendelsöarna, a undisturbed reference area. READ MORE
