  1. 1. Possible Bow Shock Current Closure to Earth's High Latitude Ionosphere on Open Field Lines

    University essay from Umeå universitet/Institutionen för fysik

    Author : Gabriella Nordin; [2023]
    Keywords : Space Physics; Bow Shock Current; Field-Aligned Currents; Open Field Lines;

    Abstract : The bow shock is formed due to the abrupt deceleration of the supersonic solar wind in front of the terrestrial magnetic field. The solar wind plasma and the Interplanetary Magnetic Field (IMF) are both compressed across the shock, and according to Ampère's law a current thus flows on the bow shock at all times. READ MORE

  3. 2. “Always been an Alien” - A qualitative study on how multilingual young adults experience and navigate identity and belonging in Skopje, North Macedonia.

    University essay from Göteborgs universitet/Institutionen för socialt arbete

    Author : Milan Wall Kovacevski; [2022-12-12]
    Keywords : Ethnicity; Social Work; Identity; Belonging; Multilingual; Young Adults; North Macedonia;

    Abstract : This study offers empirical arguments for how multilingual young adults navigate and experience identity and belonging in Skopje. A city reported to be, one of the most multicultural cities in South-East Europe, where ethnic exclusion and interethnic segregation is outmost present (Veron, 2016:1448; Stojanov, 2020:74).

  4. 3. The Investigation of Crack Propagation in Cortical Bone using a Phase Field Fracture Approach

    University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

    Author : Olivia Karlsson; [2022]
    Keywords : Cortical Bone; Cortical bone microstructure; Phase field; Phase field fracture approach; Crack propagation; Technology and Engineering;

    Abstract : Human cortical bone tissue is a complex and strong composite material, with the ability to resist damage via slowing, stopping or redirecting propagating cracks. However, the ability is impaired with age. At the microscale, changes are seen both in terms of increased porosity and as changes in local material parameters. READ MORE

  5. 4. Bow shock current closure to Earth's polar ionosphere - A statistical study using AMPERE and OMNI data

    University essay from Umeå universitet/Institutionen för fysik

    Author : Eva Krämer; [2021]
    Keywords : ;

    Abstract : The bow shock current is hypothesized to connect to the Earth's magnetosphere on open field lines and to contribute as a field aligned current to the polar ionospheric currents. In order to investigate this, two years of AMPERE data are used to compute the average region 1 currents, and average currents within the polar cap boundary, under different interplanetary magnetic field (IMF) clock angles and IMF magnitudes.

  6. 5. Carbon Abundance in the Milky Way Galaxy

    University essay from Lunds universitet/Astronomi - Genomgår omorganisation

    Author : Calum Kvernes Macpherson; [2021]
    Keywords : Carbon; Abundance; Milky Way; Chemical Evolution; Physics and Astronomy;

    Abstract : Carbon is the fourth most abundant element after hydrogen, helium and oxygen. It is a product of stellar nucleosynthesis as well as it being an important bio signature for life; this makes the analysis of carbon very fundamental. READ MORE
