    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

  4. 3. Dynamics of forest soil chemistry

    Författare :Mattias Alveteg; Avdelningen för kemiteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical technology and engineering; critical loads; regional; recovery; acidification; modelling; SAFE; MAKEDEP; Kemiteknik och kemisk teknologi; Environmental technology; pollution control; Miljöteknik; kontroll av utsläpp;

    Sammanfattning : Acidification caused by emissions of Nitrogen and Sulphur and associated adverse effects on forest ecosystems has been an issue on the political agenda for decades. Temporal aspects of soil acidification and/or recovery can be investigated using the soil chemistry model SAFE, a dynamic version of the steady-state model PROFILE used in critical loads assessment on the national level, e.

    Sammanfattning : Over one billion people live in poverty around the world. Access to modern energy sources such as electricity is considered important in social and economic development. LÄS MER

  7. 5. Acoustical Measurements of Material Nonlinearity and Nonequilibrium Recovery

    Författare :Kristian Haller; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; nonlinear acoustics; nondestructive testing; activation density; slow dynamics; nonequilibrium recovery; resonance frequency; nonlinear wave modulation spectroscopy; harmonic generation; trapped modes; open resonator; sweep rate; constant strain sweep;

    Sammanfattning : A damaged material or a material with non perfect atomic geometry, dislocations or cracks, exhibits two types of characteristic responses to acoustic excitations. First is the fast nonlinear dynamics response that is present as long as the material is excited. As soon as the excitation stops the response disappear. LÄS MER
