  1. 1. Space Plasma Dynamics : Instabilities, Coherent Vortices and Covariant Parametrization

    Författare :David Sundkvist; Jan-Erik Wahlund; Andris Vaivads; Stuart Bale; Uppsala universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Space and plasma physics; space physics; plasma; instabilities; turbulence; coherent structures; vortex; self-organization; magnetosphere; waves; electromagnetism; covariant; space instrumentation; Rymd- och plasmafysik; Space physics; Rymdfysik;

    Sammanfattning : The magnetospheric cusps are two funnel-like regions of Earth's magnetosphere where solar wind plasma can have direct access to the ionosphere. The cusps are very dynamic regions where wave-particle interactions continuously take place and redistribute energy among different particle populations. LÄS MER

  2. 2. Space Craft : Globalization and Governmentality in Regional Development

    Författare :Andreas Öjehag-Pettersson; Mikael Granberg; Hans Lödén; Malin Rönnblom; Wendy Larner; Karlstads universitet; []
    Nyckelord :SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; Assemblage; Space; Territory; Multimodal Discourse Analysis; Innovation; Competitiveness; Statsvetenskap; Political Science;

    Sammanfattning : This thesis explores two related purposes. First, it theoretically investigates how the broad literature on globalization is nested in debates concerning the nature of concepts such as space and territory. LÄS MER

  3. 3. Waves in space plasmas : Lower hybrid cavities and simple-pole distribution functions

    Författare :Anders Tjulin; Mats André; Hans Pécseli; Uppsala universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Space and plasma physics; space physics; plasma; waves; dispersion relations; lower hybrid cavities; Cluster; magnetosphere; Rymd- och plasmafysik; Space physics; Rymdfysik;

    Sammanfattning : Waves are a fundamental feature in many parts of physics, since they transport energy without transporting matter. This is the case also in space physics. Waves are responsible for energy transport both between different parts of space and between different particles in the space plasma. LÄS MER

  4. 4. The importance of waves in space plasmas : Examples from the auroral region and the magnetopause

    Författare :Gabriella Stenberg; Umeå universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Space and plasma physics; Plasma waves; magnetospheric physics; magnetopause; auroral region; wave distribution function; space exploration; reconnection; current tubes; Rymd- och plasmafysik; Space physics; Rymdfysik; rymdfysik; Space Physics;

    Sammanfattning : This thesis discusses the reasons for space exploration and space science. Space plasma physics is identified as an essential building block to understand the space environment and it is argued that observation and analysis of space plasma waves is an important approach.Space plasma waves are the main actors in many important processes.

  5. 5. Det norrländska rummet : Vardagsliv och socialt samspel i medeltidens bondesamhälle

    Författare :Anna Lagerstedt; Gert Magnusson; Anders Ödman; Stockholms universitet; []
    Nyckelord :HUMANITIES; HUMANIORA; HUMANIORA; HUMANITIES; social hierarchies; craft; outland use; rural settlement; social space; Ängersjö; Björka; Kyrklägdan; Archaeology subjects; Arkeologiämnen;

    Sammanfattning : This dissertation focus on the social structure in the Norrlandic society during the Middle Ages. In the study of social relations I have proceeded from the way that daily life is expressed in two social spaces: the village and the farm. LÄS MER
