  1. 1. Childhood family structure in 16 European countries

    Master-uppsats, Stockholms universitet/Sociologiska institutionen

    Författare :Andreas Gustafsson; [2024]
    Nyckelord :child outcomes; Europe; comparative; divorce; stepfamily; sequence analysis;

    Sammanfattning : At the end of the 20th century we saw great changes in family dynamics with rates ofseparation and re-partnerning increasing across Europe. Previous research has primarilyfocused on adults but less is known about how these family demographic changes haveaffected children's family structure. LÄS MER

  2. 2. Gravitational Collapse of a Massless Scalar Field in a Theory of Minimally Modified Gravity

    Master-uppsats, KTH/Fysik

    Författare :Atabak Fathe Jalali; [2024]
    Nyckelord :Theoretical physics; astrophysics; modified gravity; minimally modified gravity; gravitational collapse; VCDM; scalar collapse; apparent horizon; numerical relativity; Teoretisk fysik; astrofysik; modifierad gravitation; minimalt modifierad gravitation; gravitationskollaps; VCDM; skalär kollaps; uppenbar horisont; numerisk relativitet;

    Sammanfattning : This thesis explores the spherically symmetric gravitational collapse of a massless scalar field in a minimally modified gravity theory denoted VCDM (V replaces $\Lambda$ in the $\Lambda$CDM abbreviation), a class of theories propagating the same degrees of freedom as general relativity at the expense of broken 4D diffeomorphism invariance. Numerical evolution of the equations of motion reveals that for small initial scalar profile amplitudes, no black hole forms from the collapse. LÄS MER

  3. 3. Petrological, geochemical and structural evidence of fluid-rock interaction in the Siljan Ring

    Kandidat-uppsats, Stockholms universitet/Institutionen för geologiska vetenskaper

    Författare :William Crang; [2024]
    Nyckelord :methane; hydrothermal fluids; fluid-rock interaction; impact craters; reduction haloes; pyrite preservation; Siljan Ring;

    Sammanfattning : The Siljan Ring in Dalarna, Sweden is the site of the largest meteor impact crater in Europe and has long been a topic of discussion regarding methane production. However, the source of this methane and the timing of production in relation to the impact remain unclear. LÄS MER

  4. 4. Measuring copper abundances in the Galactic Bulge

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

    Författare :Nikolei Höglinger; [2024]
    Nyckelord :Copper; Galaxy: abundances; Galaxy: bulge; Chemical Evolution; Physics and Astronomy;

    Sammanfattning : Context: The chemical evolution of Cu in the Galactic bulge have been studied in a few studies using red giant branch stars, but the ages of individual red giant stars are difficult to determine. In addition, the bulge has been a challenging region of the Milky Way galaxy to obtain high-resolution spectra of stars, except when observing through certain few small fields into the bulge that are known to have low extinction.

  5. 5. Dual Cultural Influences and Career Paths: : Second-Generation Iranians in Sweden

    Kandidat-uppsats,

    Författare :Khazar Amini; [2024]
    Nyckelord :Cultural Capital; Field; Habitus; Identity Formation; Iranian Culture; Second-generation Iranians in Sweden;

    Sammanfattning : Nearly four decades after the peak influx of Iranian immigrants to Sweden around 1985-1990, recent academic inquiry has begun to shift its emphasis towards their second generation. These individuals, born to parents who arrived during that period, are now achieving notable positions across various sectors of Swedish society. LÄS MER
