1. 1. In situ remediation of contaminated sediments using thin-layer capping : efficiency in contaminant retention and ecological implications

   Författare :Göran S. Samuelsson; Jonas S. Gunnarsson; Bart Koelmans; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Contaminated Sediment Remediation; Activated Carbon; Benthic Community; Ecological Effects; Stress; Resilience; Contaminant Sequestration; Capping Efficiency; Bioavailability; Bioaccumulation; Sediment-to-water fluxes; marin ekotoxikologi; Marine Ecotoxicology;

   Sammanfattning : Hydrophobic organic contaminants (HOCs) often reside in sediments sorbed to particles, most tightly to particles with high content of organic carbon. If persistent, such pollutants can accumulate in the sediment for many years and constitute a contamination risk for sediment-living organisms and organisms at higher trophic levels, including humans.

4. 3. Hydromechanical Behaviour of Fractures Close to Tunnels in Crystalline Rock

   Författare :Johan Thörn; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Fracture stiffness; Fracture geometry; Laboratory experiments; Äspö HRL; Rock stress; In situ; Deformation measurement; Hallandsås; Hydromechanical coupling; Geological history;

   Sammanfattning : The deformation and stiffness properties of rock fractures are important measurable parameters when describing their hydromechanical behaviour. Deformation refers to aperture change. Stiffness refers to the amount of deformation per stress change to which a fracture is subjected. LÄS MER

5. 4. Thin metal films on weakly-interacting substrates : Nanoscale growth dynamics, stress generation, and morphology manipulation

   Författare :Andreas Jamnig; Kostas Sarakinos; Gregory Abadias; Gregory Thompson; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Thin films; magnetron sputter-deposition; in situ and real-time characterization; early film growth stages; residual stress; manipulation of morphology; Couches minces; pulvérisation magnétron; caractérisation in situ en temps réel; premiers stades de croissance; contraintes résiduelles; manipulation de morphologie;

   Sammanfattning : Vapor-based growth of thin metal films with controlled morphology on weakly-interacting substrates (WIS), including oxides and van der Waals materials, is essential for the fabrication of multifunctional metal contacts in a wide array of optoelectronic devices. Achieving this entails a great challenge, since weak film/substrate interactions yield a pronounced and uncontrolled 3D morphology. LÄS MER

7. 5. Endoplasmic Reticulum Dynamic Structural Changes in Neurons: The Fission-Fusion Phenomena

   Författare :Krzysztof Kucharz; Sektion IV; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; fragmentation; fission; endoplasmic reticulum; neurons; FRAP; primary cultures; organotypic slice cultures; in vivo; in situ; calcium; fusion; NMDA receptor; 2-photon microscopy; confocal microscopy;

   Sammanfattning : The endoplasmic reticulum (ER) is crucial for protein synthesis and protein maturation, is involved in cell stress and serves in neurons as the major intracellular Ca2+ store. Neuronal ER forms a continuous network of cisterns and tubules extending from soma to a subset of dendritic spines. LÄS MER
