  1. 21. Essays on Natural Resource Economics

    Författare :Godwin Kofi Vondolia; Göteborgs universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; natural resource management; bribery; social exclusion; spatial fishery management; exclusive economic zone; contingent valuation; payment vehicles; soil and water conservation; fertilizer subsidy;

    Sammanfattning : Paper 1: Enforcement of exogenous environmental regulation, social disapproval and bribery Many resource users are not directly involved in the formulation and enforcement of resource management rules and regulations in developing countries. As a result, resource users do not generally accept such rules. LÄS MER

  3. 22. Mass Conserving Simulations of Two Phase Flow

    Författare :Elin Olsson; Gunilla Kreiss; Stig Larsson; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; free boundary; two phase flow; level set method; conservative; Numerical analysis; Numerisk analys;

    Sammanfattning : Consider a mixture of two immiscible, incompressible fluids e.g. oil and water. Since the fluids do not mix, an interface between the two fluids will form and move in time. LÄS MER

  4. 23. Phase-changing flows: numerical methods and fully resolved simulations

    Författare :Nicolo Scapin; Luca Brandt; Christophe Duwig; Outi Tammisola; Matthias Ihme; KTH; []
    Nyckelord :Phase change; interface-resolved simulations; compressibility; evaporating droplets; evaporation-driven thermal convection.; Teknisk mekanik; Engineering Mechanics;

    Sammanfattning : Flows with evaporation and boiling are abundant in different contexts, such as geophysics, the biomedical sectors, and industrial applications. Spray combustion, boiling bubble flows, oceanic sprays, formation and evolution of clouds, spreading of infectious diseases are all relevant examples where a deeper understanding of phase-changing flows is of great importance.

  5. 24. Managing Mangrove Ecosystem Services for Local Livelihoods and Adaptations in Tanzania

    Författare :Baraka Nyangoko; Håkan Berg; Martin Gullström; Mwita Mangora; Mwanahija Shalli; Johan Hollander; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mangroves; ecosystem services; mangrove management; livelihoods; ecosystem-based adaptation; Tanzania; naturgeografi; Physical Geography;

    Sammanfattning : Recognizing the importance of ecosystem services (ES) for peoples' livelihoods and well-being is important for decision-making processes on conservation. Mangrove ecosystems in Tanzania are protected by law, but they continue to be exposed to degradation and loss, and there is still limited information about the awareness, preferences, status and trends of the ES they provide.

  7. 25. Magnetic helicity in astrophysical dynamos

    Författare :Simon Candelaresi; Axel Brandenburg; Renzo Ricca; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Astronomy; astronomi;

    Sammanfattning : The broad variety of ways in which magnetic helicity affects astrophysical systems, in particular dynamos, is discussed.The so-called alpha effect is responsible for the growth of large-scale magnetic fields. The conservation of magnetic helicity, however, quenches the alpha effect, in particular for high magnetic Reynolds numbers. LÄS MER
