1. 1. Formation of solar bipolar regions : Magnetic flux concentrations from suction of the negative effective magnetic pressure instability

   Författare :Illa Rivero Losada; Axel Brandenburg; Matthias Rempel; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Magnetohydrodynamics MHD ; turbulence; dynamo; Sun: magnetic fields; Sun: rotation; Sun: activity; Sun: dynamo; Astronomy; astronomi;

   Sammanfattning : Sunspots stand out on the visible solar surface. They appear as dark structures evolving and changing over time. They host energetic and violent events, like coronal mass ejections and flares, and concentrate strong magnetic fields. LÄS MER

3. 2. Origin of solar surface activity and sunspots

   Författare :Sarah Jabbari; Axel Brandenburg; Laurene Jouve; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Magneto-hydrodynamics; solar physics; dynamo theory; Astronomy; astronomi;

   Sammanfattning : Sunspots and active regions are two of the many manifestations of the solar magnetic field. This field plays an important role in causing phenomena such as coronal mass ejections, flares, and coronal heating. Therefore, it is important to study the origin of sunspots and active regions and determine the underlying mechanism which creates them. LÄS MER

4. 3. Opinionens mekanismer : Om värderingar och verklighet

   Författare :Torsten Österman; Stefan Svallfors; Stockholms universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Sociology; Sociologi; Sociology; sociologi;

   Sammanfattning : A significant characteristic of our time is the accelerating speed and increased volume ofinformation, where events and information about events form an interacting dynamo. The traitsand abilities of individuals and society to handle and respond to that flow of informationdeserve political attention. LÄS MER
