  1. 41. Solid waste and the water enviroment in the new European Union perspective

    Författare :Marcia Marques; KTH; []
    Nyckelord :;

    Sammanfattning : Processes that occur during storageand final disposal ofsolid waste were studied, with emphasis on physical andchemical aspects and their effects on the water environment,within the New European Union perspective for landfilling(Council Directive 1999/31/EC, 1999).In the new scenario, landfilling is largely restricted;waste treatments such as incineration, composting, recycling,storage and transportation of materials are intensified.

  3. 42. Indoor emissions and fate of flame retardants : A modelling approach

    Författare :Ioannis Liagkouridis; Ian Cousins; Anna Palm Cousins; Thomas McKone; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; flame retardants; BFRs; OPFRs; indoor environment; emissions; fate; modelling; Applied Environmental Science; tillämpad miljövetenskap;

    Sammanfattning : A significant number of consumer goods and building materials act as emission sources of flame retardants (FRs) in the indoor environment. As a result, FRs have become ubiquitous indoors raising concerns about human exposure and possible health implications. LÄS MER

  4. 43. Advanced Laser-based Multi-scalar Imaging for Flame Structure Visualization towards a Deepened Understanding of Premixed Turbulent Combustion

    Författare :Bo Zhou; Förbränningsfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Laser Diagnostics; PLIF; High Spatial Resolution; Multi-scalar Instantaneous Visualization; HCO CH Radicals; Distributed Reaction Zone; Mild Combustion.; Combustion Regimes; Turbulence Flame Interaction; Turbulent Premixed Combustion; Fysicumarkivet A:2015:Zhou;

    Sammanfattning : The work presented in the thesis concerns the developments of laser-based diagnostics and its application to the study of turbulent premixed combustion. The diagnostic developments, mainly concerned with planar laser-induced fluorescence (PLIF), are intended to provide instantaneous visualization of the key species originating from the combustion processes involved in the burning of hydrocarbons and nitrogen-containing fuels under turbulent conditions.
