  1. 6. Process based Modelling of Chemical and Physical Aerosol Properties Relevant for Climate and Health

    Författare :Pontus Roldin; Kärnfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; gas phase chemistry; aerosol dynamics; aerosol particles; climate; kinetic multilayer model; Fysicumarkivet A:2013:Roldin;

    Sammanfattning : Atmospheric aerosol particles have substantial influence on climate and air quality. However, the anthropogenic influence on the atmospheric aerosol is still poorly known. This limits the understanding of past and future climate changes. LÄS MER

  3. 7. Carbon dynamics in spruce forest ecosystems - modelling pools and trends for Swedish conditions

    Författare :Magnus Svensson; Per-Erik Jansson; Dan Berggren Kleja; Keith Paustian; KTH; []
    Nyckelord :boreal; climate; CoupModel; net ecosystem production; nitrogen; process-based model; soil carbon; NATURAL SCIENCES; NATURVETENSKAP;

    Sammanfattning : Carbon (C) pools and fluxes in northern hemisphere forest ecosystems are attracting increasing attention concerning predicted climate change. This thesis studied C fluxes, particularly soil C dynamics, in spruce forest ecosystems in relation to interactions between physical/biological processes using a process-based ecosystem model (CoupModel) with data for Swedish conditions.

  4. 8. Towards Bridging the Gap Between Strategy and Operations - A Process Based Framework

    Författare :Dag Näslund; Teknisk logistik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Logistics; Strategy; Operations; Organizational Change; Middle Manager; Teknik; Technological sciences; Process;

    Sammanfattning : This dissertation is about bridging the gap between strategy and operations in organizations. To bridge that gap, processes are viewed not only from an operational perspective but also from conceptual, as well as a hierarchical perspectives. LÄS MER

  5. 9. Modeling of new particle formation and growth in the atmospheric boundary layer

    Författare :Emilie Öström; Centrum för miljö- och klimatvetenskap (CEC); []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; New particle formation; Secondary organic aerosols; Process-based modeling; Climate;

    Sammanfattning : Atmospheric aerosols affect climate, but to what degree still remains one of the largest uncertainties in global climate models. To improve the representation of aerosols in future climate models we need a greater understanding of aerosol processes. LÄS MER

  7. 10. Generation of Leachate and the Flow Regime in Landfills

    Författare :David Bendz; Avdelningen för Teknisk vattenresurslära; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; teknisk geologi; Hydrogeologi; geographical and geological engineering; Hydrogeology; model; transport; flow; leachate; water; hydrology; landfill; MSW; teknisk geografi; Geophysics; physical oceanography; meteorology; Geofysik; fysisk oceanografi; meteorologi;

    Sammanfattning : The environmental impacts of landfills are associated mainly with the emission of leachate and biogas. Sanitary landfilling aims to stabilize the landfill in a efficient and controlled way, so that the environmental impacts are minimized. When a sanitary landfill has attained its final storage quality, it can be integrated into the environment. LÄS MER
