    Sammanfattning : Magnetosheath high-speed jets are transient and localized dynamic pressure enhancements downstream of Earth’s bow shock. Their formation has been associated with several mechanisms, including solar transient events and the dynamical evolution of the bow shock. LÄS MER

    Sammanfattning : This thesis is based on six papers, Papers I-VI, focusing on the interplay between the stabilizing elements of nucleic acids self-assembly; hydrogen bonding, stacking and solvent effects. In Paper I we investigate how the substitution of the O4' for CH2 in the sugar moiety of adenosine (2'-deoxyaristeromycin) at the A6 position of the Dickerson-Drew dodecamer makes the two modified bases exist in a dynamic equilibrium between Hoogsteen and Watson-Crick base pairing in the NMR time scale.
