  1. 1. 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. 2. Rysslands roll i inbördeskriget i Syrien utifrån ett realistiskt, konstruktivistiskt respektive ett liberalistiskt perspektiv : Teorikonsumerande fallstudie om Rysslands roll i det syriska inbördeskriget

    Kandidat-uppsats, Linnéuniversitetet/Institutionen för statsvetenskap (ST)

    Författare :Eiad Aldroubi; [2024]
    Nyckelord :Ryssland; Syrien; realism; Konstruktivism; Liberalism; Inbördeskrig;

    Sammanfattning : The Russian invasion of Ukraine has raised interests in Russia’s foreign policy. One of the widely unexplored parts of that is Russia’s role in the Syrian civil war. Saving the Syrian regime from total collapse in Syria Russia played a key role in the conflict. LÄS MER

  4. 3. Hur blir ett land egentligen demokratiskt - En fallstudie om Mongoliets demokratiseringsprocess efter Sovjetunionens fall

    L2-uppsats, Lunds universitet/Statsvetenskapliga institutionen

    Författare :Filip Alemo; Oscar Malmgren; [2024]
    Nyckelord :Demokratisering; Mongoliet; institutionell design; civilsamhälle; globalisering; Law and Political Science;

    Sammanfattning : How do countries really transition from autocracy to democracy? In the case of Mongolia, the country underwent a democratic revolution in the end of the 1980s and early stages of the 90s. The country implemented multi-party elections and civil rights, even though the communist party stayed in power following the first democratic election in 1990. LÄS MER

  5. 4. Visualisering av tystade historier - En dekolonial kulturanalys av verket I firandet av vår kamp finns deras undergång

    Master-uppsats, Göteborgs universitet/Institutionen för kulturvetenskaper

    Författare :Jennifer Turano; [2023-08-09]
    Nyckelord :Memorials; Whiteness; Non-whiteness; Decolonial artivism; Decolonial theory; Post-immigrant generations; Racism; Memory;

    Sammanfattning : The dominant narrative of history, prevalent in Sweden, is of a country which has no structural racism and that had no part in the colonization of the Americas or in the transatlantic slave trade. This is far from the truth, and this study connects Sweden’s role in the slave trade and as a country with colonial ambitions, as well as its history of racial biology, with the racialization of non-white bodies.

  7. 5. Why the Islamic Republic of Afghanistan (2004-2021) Collapsed? The Path to Peace after the Rise of the Taliban 2.0

    Master-uppsats, Göteborgs universitet/Statsvetenskapliga institutionen

    Författare :Sultan Ghulam Dastgir Sani; [2023-06-20]
    Nyckelord :Collapsed State; The Role of Parliamentarians in Peace Processes; Autocratization; Fundamentalism; Armed Politics;

    Sammanfattning : With the fall of Kabul on 15 August 2021, Afghanistan has been back to where it was in 2001, a closed autocracy ruled by the Taliban. However, it was required to search out why the Islamic Republic of Afghanistan 2004-2021 collapsed. LÄS MER
