  1. 1. The effect of nozzle geometry on bubble formation : Physical modeling by air in a water tank

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Mhd Osman Bernieh; [2023]
    Keywords : Nozzle geometry; bubble formation; water tank model; bubble flow; Munstycksgeometri; bubbelbildning; vattentankmodell; bubbelflöde;

    Abstract : The bubble flow is used for different application in steel production and refining processes. It plays in indispensable role in the ladle refining process such as for homogenization and inclusion removal. Hence, it is important to understand the effect of the nozzle outlet geometry on the bubble formation. READ MORE

  3. 2. Prevalence of mental illness, and the demographic and socio-economic conditions that are associated with the self-rated mental health in an adult population in Sweden : A cross-sectional study

    University essay from

    Author : Mhd Nizar Naji Alhayek; [2023]
    Keywords : ;

    Abstract : Bakgrund: Andelen av den svenska befolkningen som rapporterade psykiska problem har ökat under de senaste decennierna och särskilt de senaste åren, vilket bekräftar betydelsen av att monitorera den psykiska hälsan i befolkningen. Syfte: Att undersöka förekomsten av psykiska problem i en population av svenska vuxna, och att analysera de oberoende sambanden mellan de demografiska och socioekonomiska förhållandena och mellan självskattat psykiskt välbefinnande och psykisk påfrestning.

  4. 3. Parental mental health after having a child placed in out-of-home care in Sweden : A register-based longitudinal cohort study

    University essay from Stockholms universitet/Institutionen för folkhälsovetenskap

    Author : Tanishta Rajesh; [2022]
    Keywords : ;

    Abstract : Children in out-of-home care (OHC) experience poor outcomes in almost every dimension of life. However, much less attention has been given to their birth parents who also face several co-existing challenges. This study examines the association between OHC placement of a child and changes in mental health disorders (MHD) in their parents. READ MORE

  5. 4. An analysis of the turbulent properties of a CME

    University essay from Uppsala universitet/Institutionen för fysik och astronomi; Uppsala universitet/Institutet för rymdfysik, Uppsalaavdelningen

    Author : Roque Márquez Rodríguez; [2022]
    Keywords : CME; turbulence; plasma; solar wind; MHD;

    Abstract : Spectral indices and flatness scaling exponents corresponding to solar wind plasma measurements before, during and after a coronal mass ejection (CME) detected by NASA's Wind spacecraft on September 2014 have been obtained. The Politano-Pouquet (PP) law for isotropic and incompressible magnetohydrodynamic (MHD) turbulence has been validated over a series of selected time intervals. READ MORE

  6. 5. On the Interaction Between Electromagnetic, Gravitational, and Plasma Related Perturbations on LRS Class II Spacetimes

    University essay from Umeå universitet/Institutionen för fysik

    Author : Philip Semrén; [2021]
    Keywords : ;

    Abstract : In this thesis, we investigate the interaction between electromagnetic, gravitational, and plasma related perturbations on homogeneous and hypersurface orthogonal Locally Rotationally Symmetric (LRS) class II spacetimes. By using these spacetimes, which allow for the inclusion of a non-zero magnetic field, as backgrounds in a perturbative approach, we are able to see interactions between the electromagnetic and gravitational variables already to first order in the perturbations.
