2. 1. Neural processes underpinning pain perception : genetic, temporal, and behavioral factors

   Author : Gránit Kastrati; Karolinska Institutet; Karolinska Institutet; []
   Keywords : ;

   Abstract : Pain is an alarm system – warning us of dangers in the environment – yet becomes problematic when it transitions into chronic pain. It is defined, according to the International Association of Pain as “An unpleasant sensory and emotional experience associated with, or resembling that associated with, actual or potential tissue damage”.

4. 2. The Collective Action Dilemma in Managing Transboundary Freshwaters : An Analysis of an Outcome-Driven Framework

   Author : Jakob Granit; Carl Christiansson; Helle Skånes; Aaron Wolf; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Benefit generation; common-pool resources; governance; management; outcomes; regional public goods; transboundary waters; value chain; geografi med naturgeografisk inriktning; Geography; Physical Geography;

   Abstract : It is recognised by society that freshwater resources play a major role in economic development and in maintaining life supporting ecosystems services. Transboundary river basins cover about 45% of the earth’s land surface and their governance is therefore of critical importance. READ MORE

5. 3. Studies on the frost resistance of natural stone

   Author : Lubica Wessman; Avdelningen för Byggnadsmaterial; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; äldre byggnader; kalksten; laboratorieförsök; sten; granit; sandsten; natursten; frostbeständighet; beständighet;

   Abstract : This work deals with the effects of freeze-thawing on the deterioration of some types of natural stone, especially stones frequently used in old buildings in Sweden. Laboratory studies were performed mainly on Gotland sandstone. This stone has been widely used in old buildings in the whole Baltic region, and is often badly deteriorated. READ MORE

6. 4. Sveconorwegian orogenesis in the southwestern Baltic Shield - Zircon geochronology and tectonothermal setting of orthogneisses in SW Sweden

   Author : Jenny Andersson; Berggrundsgeologi; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Petrology; Geologi; fysisk geografi; physical geography; Geology; structural markers; augen gneiss; orthogneiss; migmatite; ion microprobe; Pb-Pb evaporation; U-Pb; geochronology; zircon; Sweden; Mylonite Zone; Western Segment; Sveconorwegian orogen; Eastern Segment; mineralogy; geochemistry; Petrologi; mineralogi; geokemi;

   Abstract : The Mylonite zone (MZ) is a prominent late-Sveconorwegian lithological terrane boundary in the SW Baltic Shield along which large-scale crustal block movements took place during the Sveconorwegian orogeny. The southern section of the MZ also defines a conspicuous metamorphic break separating upper amphibolite and high-pressure granulite facies rocks in the parautochthonous Eastern Segment (ES), from middle amphibolite facies rocks in the overlying Western Segment (WS).

7. 5. Numerical modeling of fluid flow and solute transport in rock fractures

   Author : Liangchao Zou; Lanru Jing; Vladimir Cvetkovic; Chin-Fu Tsang; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Rough-walled rock fractures; Nonlinear flow; Solute transport; Navier-Stokes equations; Matrix diffusion; Uncertainty.; Mark- och vattenteknik; Land and Water Resources Engineering;

   Abstract : This study focuses on numerical modeling of fluid flow and solute transport in rough-walled rock fractures and fracture-matrix systems, with the main aim to investigate the impacts of fracture surface roughness on flow and transport processes in rock fractures. Both 2D and 3D fracture models were built from laser-scanned surface tomography of a real granite rock sample, to consider realistic features of surface tomography and potential asperity contacts.
