  4. 2. Limits of functions : university students' concept development

    Author : Kristina Juter; Luleå tekniska universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Mathematics Education; Matematik och lärande;

    Abstract : Avhandlingen består av sex artiklar som föregås av en kappa. Kappan sammanfattar de teorier som använts i artiklarna, empiridelen samt resultat och slutsatser. Fem av artiklarna är publicerade i tidskrifter eller accepterade för publikation i tidskrifter och den återstående är accepterad för publicering i en konferensrapport. READ MORE

  5. 3. Aerosol Measurements as Applied for Exposure Characterization

    Author : Andreas Dahl; Ergonomi och aerosolteknologi; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; railroad; indoor air; environment; occupational health; exposure; isocyanate; airborne particles; station; traffic;

    Abstract : It is important to decrease the burden of disease. This is in part achieved by decreasing risks. The aim of this thesis is to provide a methodology for the characterization of aerosol exposure, which may lead to negative health effects. READ MORE

  6. 4. Dispersion and Transformation of Traffic Exhaust Particles in the Urban Atmosphere

    Author : Matthias Ketzel; Kärnfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; condensation; deposition; dilution; particle size distribution; plume model; street canyon; traffic pollution; urban environment; turbulence; aerosol dynamics modelling; coagulation; Physics; Fysik; Fysicumarkivet A:2004:Ketzel;

    Abstract : Ultrafine particles, their sources and fate in the atmosphere are currently key issues in atmospheric research owing to concern about their effects on human health and global climate. Traffic emissions are a dominating source of ultrafine particles, especially in urban areas. READ MORE

  7. 5. Quiescent regimes in cosmology

    Author : Hans Oude Groeniger; Hans Ringström; Mattias Dahl; Todd Oliynyk; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; quiescence; Bianchi spacetimes; big bang formation; G2 cosmology; Wainwright-Hsu variables; Klein-Gordon equation; Matematik; Mathematics;

    Abstract : This thesis is about cosmological solutions to Einstein’s equations of general relativity, in particular spacetimes whose mean curvature diverges. Moreover, we consider anisotropic spacetimes with big bang singularities. In this setting the singularity is expected to generically be oscillatory if no matter is present. READ MORE
