    Sammanfattning : Frågan som avhandlingen Suveränitetserosion? ställer är om den fortsatta utvecklingen ska vara för EU att lagstifta om eller om den, som den till övervägande del varit de senaste femtio åren, ska fortsätta utvecklas av EU-domstolen.Medlemsstaternasnationella sociala trygghetssystem är inte, och kan inte vara, opåverkade i ett unionsrättsligt sammanhang.

  3. 2. Internal Erosion Phenomena in Embankment Dams : Throughflow and internal erosion mechanisms

    Författare :Farzad Ferdos; Anders Wörman; Bijan Dargahi; Fredrik Johansson; Willi Hager; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Internal erosion modelling in porous material; Constitutive law of erosion for closure of continuum-mechanics-based balance equations for numerical modelling; High Reynolds-number turbulent flow; Flow laws; Coarse rockfill material throughflow; Computational Fluid Dynamics.; Civil and Architectural Engineering; Byggvetenskap;

    Sammanfattning :  In this study, two major internal erosion initiation processes, suffusion and concentrated leak mechanisms, which lead to both defect formation in a dam’s body and its foundation and high throughflow in dams subjected to internal erosion were studied. This understanding has the potential to facilitate numerical modelling and expedite dam safety assessment studies. LÄS MER

  5. 4. Impact of Surface Structures onDeposition and Erosion in a Tokamak

    Författare :Yushan Zhou; Henric Bergsåker; Ivancica Bogdanovic Radovic; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Deposition; erosion; JET; micro ion beam analysis; Deposition; erosion; JET; mikrojonstråleanalys; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : Fusion is a potentially unlimited and environmentally friendly energy source for human society in the future. However, along the way towards the application of fusion energy there are still unresolved complications. Among them, deposition and erosion are two critical issues. LÄS MER

  7. 5. Swash Processes and Dune Erosion: Emphasis on Vessel-Generated Waves

    Författare :Li Erikson; Avdelningen för Teknisk vattenresurslära; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; marklära; kartografi; klimatologi; Civil engineering; hydraulic engineering; geomorfologi; Fysisk geografi; climatology; cartography; pedology; geomorphology; Naturvetenskap; Physical geography; Natural science; swash; erosion; vessel-generated waves; dunes; offshore technology; soil mechanics; Väg- och vattenbyggnadsteknik;

    Sammanfattning : In navigable waterways, owing to the relatively short fetches for wind wave generation, the free waves generated by moving vessels often produce the dominant wave action with respect to erosion of the shore. In response to the fairly recent introduction of high-speed ferries, combined with a planned expansion within the passenger- and car-carrying ship market, the need to model and predict coastline changes as a result of exposure to vessel-generated waves has become a topic of increased research.
