  1. 1. "Det är månen att nå- " : en studie i några datorintresserade pojkars språk och föreställningsvärld

    Författare :Eva Erson; Umeå universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; Wittgenstein; philosophy of language; the moving example; computers; mastery; masculinist language game; hierarchization; dichotomization; power; control; Wittgenstein; Ludwig; 1889-1951; Programspråk;

    Sammanfattning : The aim of this thesis is to describe some central conceptual ideas expressed in the language of six computer interested boys. The starting-point is the philosophy of language of Ludwig Wittgenstein, where language is seen as something deeply integrated in our practices, traditions and culture. The use of our language shows its meaning. LÄS MER

  3. 2. Solar Wind Proton Interactions with Lunar Magnetic Anomalies and Regolith

    Författare :Charles Lue; Yoshifumi Futaana; Stas Barabash; Urs Mall; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; the Moon; solar wind; magnetic anomalies; regolith; space physics; plasma physics; particle-surface interactions; mini-magnetospheres; energetic neutral atoms; Space Physics; rymdfysik;

    Sammanfattning : The lunar space environment is shaped by the interaction between the Moon and the solar wind. In the present thesis, we investigate two aspects of this interaction, namely the interaction between solar wind protons and lunar crustal magnetic anomalies, and the interaction between solar wind protons and lunar regolith.

  4. 3. Object-plasma interaction in the vicinity of Enceladus

    Författare :Jonas Olson; Svetlana Ratynskaia; Padma Shukla; KTH; []
    Nyckelord :;

    Sammanfattning :     The Cassini spacecraft orbits Saturn since 2004, carrying a multitude of instruments for studies of the plasma environment around the planet as well as the constituents of the ring system. Of particular interest to the present thesis is the large E ring, which consists mainly of water ice grains, smaller than a few micrometres, referred to as dust. LÄS MER

  5. 4. Plasma Interactions with Icy Bodies in the Solar System

    Författare :Jesper Lindkvist; Mats Holmström; Martin Wieser; Elias Roussos; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; plasma interactions; icy bodies; solar system; space physics; plasma physics; hybrid model; numerical model; solar wind; magnetosphere; sub-Alfvénic; subsonic; non-collisional; atmosphereless; exosphere; coma; subsurface ocean; induction; magnetic dipole; pick-up ion; mass-loading; moon; natural satellite; dwarf planet; comet; Jupiter; Jovian; Callisto; Ceres; 67P; Churyumov-Gerasimenko; rymd- och plasmafysik; Space and Plasma Physics;

    Sammanfattning : Here I study the “plasma interactions with icy bodies in the solar system”, that is, my quest to understand the fundamental processes that govern such interactions. By using numerical modelling combined with in situ observations, one can infer the internal structure of icy bodies and their plasma environments. LÄS MER

  7. 5. Celestial Orientation in Dim Light

    Författare :Marie Dacke; Funktionell zoologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; polarisation pattern; moon; polrised light detection; twilight; dim light; dung beetle; Zoologi; spider; vision; orientation; Zoology;

    Sammanfattning : The polarization pattern of skylight offers many animals a reference for visual compass orientation. In those cases when this optical compass is identified, the receptors involved are often confined to a small part of an eye built predominantly for other visual tasks. LÄS MER
