1. 16. 3D Structure and Emplacement of the Alnö Alkaline and Carbonatite Complex, Sweden : Integrated Geophysical and Physical Property Investigations

   Författare :Magnus Andersson; Alireza Malehmir; Valentin R. Troll; Bjarne Almqvist; Odleiv Olesen; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Alnö; carbonatite; caldera; reflection seismic; anisotropy of magnetic susceptibility; gravity; magnetic; Geophysics with specialization in Solid Earth Physics; Geofysik med inriktning mot fasta jordens fysik;

   Sammanfattning : Carbonatites are carbonate-rich magmatic rocks that are rare and of great relevance for our understanding of crustal and mantle processes. Although found on all continents and in settings ranging from Archaean to present-day, their deeper plumbing system is still poorly understood. LÄS MER

3. 17. 3D-modeling of the Skellefte district using electrical, potential field and reflection-seismic data : A basis for 4D-modeling of mineral belts

   Författare :Saman Tavakoli; Lena Persson; Luleå tekniska universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Tillämpad geofysik; Applied Geophysics;

   Sammanfattning : As a part of a 4D modeling project, two studies with different scopes were conducted in the central Skellefte district (CSD), northern Sweden. The aim of the studies is to create a basis for a better understanding of the spatial relationship between geological structures and mineralization and to construct a 3D and 4D geology model of the area.

4. 18. Resistivity and Surface Wave Seismic Surveys in Geotechnical Site Investigations

   Författare :Roger Wisén; Teknisk geologi; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; teknisk geografi; Hydrogeologi; teknisk geologi; Hydrogeology; geographical and geological engineering; resistivity method; surface wave seismic method; inverse modelling; site investigation; geophysics;

   Sammanfattning : The adaptation of geophysical methods for civil engineering purposes represents an important contribution to the development of geotechnical site investigation methodology. The term geotechnical site investigation here refers to all investigations performed prior to or during construction; i.e. LÄS MER

5. 19. In Vivo Evaluation of Skeletal Muscle Morphological and Mechanical Properties using Medical Imaging

   Författare :Zhongzheng Wang; Ruoli Wang; Elena Gutierrez Farewik; Rodrigo Moreno; Jonas Stålhand; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Muscle volume; fascicle length; pennation angle; anisotropy; three-dimensional freehand ultrasound; magnetic resonance imaging; diffusion tensor imaging; magnetic resonance elastography; Muskelvolym; fascikellängd; pennationsvinkel; anisotropi; tredimensionellt frihandsultraljud; magnetisk resonanstomografi; diffusionstensoravbildning; magnetisk resonanselastografi; Teknisk mekanik; Engineering Mechanics;

   Sammanfattning : Skeletal muscles are soft tissues that play an important role in maintaining body posture and enabling movements through force generation. The force-generating capacity is associated with the morphological and mechanical properties of the muscle. LÄS MER

7. 20. Geoelectrical imaging for interpretation of geological conditions affecting quarry operations

   Författare :Mimmi K. Magnusson; Joanne Fernlund; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical resistivity imaging; Rock-mass quality; Aggregate production; Geophysical methods; Induced polarization; Normalized induced polarization; Environmental engineering; Miljöteknik;

   Sammanfattning : Determination of the subsurface geology is very important for the rock quarry industry. This is primarily done by drilling and mapping of the surface geology. However in Sweden the bedrock is often completely covered by Quaternary sediments making the prediction of subsurface geology quite difficult. LÄS MER
