  1. 1. Starshades: Geoengineering Solutions and Technosignatures in Direct Imaging Phase Curves

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

    Författare :Claudia Skoglund; [2023]
    Nyckelord :Starshades; extraterrestrial intelligence; stellar evolution; technosignatures; phase curves; direct imaging; habitable zone.; Physics and Astronomy;

    Sammanfattning : The stellar luminosity increases as a star evolves which inevitably yields a higher temperature on planets in orbit around the star. It is reasonable to assume that intelligent civilizations would tackle this issue through installing artificial structures that can alter the radiation received by the planet. LÄS MER

  3. 2. Galactic Dynamics and the spread of Galactic Civilisations

    Kandidat-uppsats, Lunds universitet/Astronomi - Genomgår omorganisation

    Författare :Markus Strickert; [2020]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : Abstract The idea of the spread of life through the galaxy is, in most minds, considered science fiction. Yet, scientists argue that most galaxies have had more than enough time for civilisation development and space travel. LÄS MER

  4. 3. Det “utomjordiska” Etiopien : En kritisk diskursanalys av framställningen av Etiopien som resmål i ett resereportage ur tidningen Vagabond

    Kandidat-uppsats, Malmö universitet/Institutionen för globala politiska studier (GPS)

    Författare :Linn Eriksson; [2020]
    Nyckelord :travel journalism; Vagabond; critical discourse analysis; Ethiopia; tourism; postcolonialism; orientalism;

    Sammanfattning : The purpose of this paper is to investigate the portrayal of Ethiopia as a destination in a travel report from the newspaper Vagabond. The method used is critical discourse analysis, based on postcolonial theory formation. The focus of the analysis is to examine how Ethiopia and its population are represented in the text. LÄS MER

  5. 4. Macromolecular Crowding as a Determinant of Protein Viability -- a Lattice Model Study

    Master-uppsats, Lunds universitet/Beräkningsbiologi och biologisk fysik - Genomgår omorganisation

    Författare :Daniel Nilsson; [2017]
    Nyckelord :Protein folding; Macromolecular crowding; HP model; Physics and Astronomy;

    Sammanfattning : We study the effects of macromolecular crowding with interacting crowders in the simple HP-model of protein folding, by performing Monte Carlo simulations of a single flexible HP protein in the presence of folded rigid crowders. In contrast to the well-known stabilization of steric crowders, we find that interacting crowders usually destabilize the test protein, often significantly so. LÄS MER

  7. 5. Chrome spinel grains from the Komstad Limestone Formation, Killeröd, southern Sweden : a high-resolution study of an increased meteorite flux in the Middle Ordovician

    Master-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Ellinor Martin; [2014]
    Nyckelord :chrome spinel; fossil meteorites; Komstad Limestone; winonaites; Middle Ordovician; carbonate sedimentology; Earth and Environmental Sciences;

    Sammanfattning : I mellersta ordovicium var inflödet av kosmiskt material till jorden högre än idag, i sviter-na efter uppbrytningen av den L-kondritiska asteroidkroppen i asteroidbältet mellan Mars och Jupiter, vilket beri-kade den forna havsbottnen med meteoriter och kosmiskt damm. Komstadformationen i Killeröd, Skåne, innehåller ett lager särskilt rikt på L-kondritiska kromitkorn vilket indikerar en hög grad av kondensation. LÄS MER
