   Författare :Gustaf Svedjemo; Frands Herschend; Helene Martinsson-Wallin; Jan Henrik Fallgren; Uppsala universitet; []
   Nyckelord :HUMANIORA; HUMANITIES; Gotland; Archaeology; History; Historical maps; Roman Iron Age; Migration Period; Middle Ages; Village; Village formation; Farm; Settlement archaeology; Spatial analyses; GIS; Prediction modelling.; Gotland; Arkeologi; Historia; Historiska kartor; Romersk järnålder; Folkvandringstid; By; Bybildning; Gård; Bebyggelsearkeologi; rumsliga analyser; GIS; Geografiska informationssystem; prediktionsmodellering;

   Sammanfattning : This dissertation deals with the long-term dynamics and fluctuations of settlements on Gotland for the period from AD 200 up until early modern times. The settlement structure on Gotland is most often described as very stable and consisting of solitary farms, established in the Iron Age. LÄS MER

3. 12. Sunspot structure and dynamics

   Författare :Luc Rouppe van der Voort; Wolfgang Schmidt; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Astronomy; Astronomi; Astronomy; astronomi;

   Sammanfattning : Fundamental physical processes occur on small spatial scales in the solar atmosphere and high-spatial-resolution observations are necessary to test theoretical models. This thesis presents high-spatial-resolution observations of sunspots obtained with the Swedish solar telescopes on La Palma: the Swedish Vacuum Solar Telescope (SVST) and its successor the Swedish 1-m Solar Telescope (SST).

4. 13. Structure, Dynamics and Thermodynamics of Liquid Water : Insights from Molecular Simulations

   Författare :Kjartan Thor Wikfeldt; Lars G. M. Pettersson; Francesco Sciortino; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Liquid water; supercooled water; diffraction; structure modeling; molecular dynamics; x-ray spectroscopy; EXAFS; SAXS; Physics; Fysik; Theoretical Physics; teoretisk fysik;

   Sammanfattning : Water is a complex liquid with many unusual properties. Our understanding of its physical, chemical and biological properties is greatly advanced after a century of dedicated research but there are still many unresolved questions. LÄS MER

5. 14. Tales from the Sweet Side of Life : Structure and dynamics of carbohydrate-based systems

   Författare :Alessandro Ruda; Göran Widmalm; Jesús Jiménez Barbero; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; carbohydrates; nuclear magnetic resonance; molecular dynamics; glycans; conformational analysis; structure elucidation; protein-glycan interactions; Organic Chemistry; organisk kemi;

   Sammanfattning : The field of glycomics has experienced significant developments in the last few decades, revealing a profound and elaborate language behind the intrinsic complexity of the glycans structures. This ‘sugar code’ is at the basis of intercellular interaction and recognition. For this language to be understood, its chemical basis must be unveiled. LÄS MER

7. 15. Concentrated DNA-amphiphiles Structure, Hydration, and Dynamics

   Författare :Cecilia Leal; Fysikalisk kemi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; amphiphiles; DNA; Physical chemistry; diffusion NMR; solid-state NMR; electrostatics; dynamics; local order; Fysikalisk kemi; hydration;

   Sammanfattning : The structure, hydration, and dynamics of concentrated DNA-amphiphile complexes were investigated by small-angle X-ray diffraction, sorption calorimetry, and nuclear magnetic resonance. A concentrated, electroneutral, DNA-amphiphile complex can be formed by mixing charge-stoichiometric solutions. LÄS MER
