    Författare :Jeroen van Eldert; Håkan Schunnesson; Daniel Johansson; David Saiang; Thomas Dalmalm; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Blast damage; Excavation Damage Zone; EDZ; Measurement While Drilling; MWD; Rock support; Rock mass characterisation; Tunnelling; Mining and Rock Engineering; Gruv- och berganläggningsteknik;

    Sammanfattning : Prior to an underground excavation a site investigation is carried out. This includes reviewing and analysing existing data, field data collected through outcrop mapping, drill core logging and geophysical investigations. LÄS MER

  3. 12. Seismic structure of the central Svecofennian lithosphere

    Författare :Sebastian Buntin; Alireza Malehmir; Christopher Juhlin; Michał Malinowski; Raymond Durrheim; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Wide-angle reflection refraction seismic; near-vertical incidence seismic; Moho; crust-mantle boundary; saucer-shaped sill; BABEL; FENNOLORA; UPPLAND; Fennoscandian Shield; Bergslagen; Uppland Batholith; Geofysik med inriktning mot fasta jordens fysik; Geophysics with specialization in Solid Earth Physics;

    Sammanfattning : Lithospheric structures in the Fennoscandian Shield in Sweden have been studied by a number of large-scale wide-angle seismic reflection/refraction (WARR) and normal-incidence reflection profiles since the 1960s. Among these were the over 2000 km long Fennoscandian Long Range (FENNOLORA) project in 1979 and the Baltic and Bothnian Echoes from the Lithosphere (BABEL) in 1989, which provided valuable images of the subsurface down to over 60 km depth including the Moho.

  4. 13. Cereal husbandry and settlement : Expanding archaeobotanical perspectives on the southern Scandinavian Iron Age

    Författare :Radoslaw Grabowski; Karin Viklund; Hans Peter Stika; Umeå universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; cereal cultivation; iron age; southern Scandinavia; archaeobotany; settlement archaeology; environmental archaeology; miljöarkeologi; Archaeology; arkeologi;

    Sammanfattning : The here presented PhD project explores the phenomenon of cereal cultivation during the Iron Age (c. 500 BC – AD 1100) in southern Scandinavia. The main body of the thesis consists of four articles. LÄS MER

  5. 14. Seismic stratigraphy and tectonics offshore Scania, south-western Baltic Sea

    Författare :Wasim Paracha; Boris Winterhalter; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Earth sciences; Geovetenskap; allmän och historisk geologi; General and Historical Geology;

    Sammanfattning : Geophysical data and descriptions of deep wells, produced during hydrocarbon explorations in the south-western part of the Baltic Sea offshore Scania, have revealed new information on the geological development of the area. This investigation is concentrated to the offshore triangular segment between the northwest-southeast Permian Sorgenfrei-Tornquist Zone through Scania and the east-west Caledonian Front north of Rügen.

  7. 15. Assessment of hydrogeological and water quality parameters, using MRS and VES in the Vientiane Basin, Laos

    Författare :Nils Perttu; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Tillämpad geofysik; Applied Geophysics;

    Sammanfattning : Water is essential for all life on the planet, sustaining and ensuring the earth's ecosystem. Groundwater from a global perspective provides about 50% of the potable water supplies, 40% of the industrial water and 20% of the irrigated agriculture. LÄS MER
