  1. 1. Dödsbränder i Sverige : En analys av datakvalitet, orsaker och riskmönster

    Författare :Anders Jonsson; Finn Nilson; Carl Bonander; Henrik Jaldell; Marie Hasselberg; Karlstads universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Fire; Risk; Mortality; Epidemiology; Brand; Risk; Mortalitet; Epidemiologi; Risk and Environmental Studies; Risk- och Miljöstudier;

    Sammanfattning : Risken att omkomma genom brand har mer än halverats under de senaste 60 åren i Sverige. Det är idag mycket ovanligt att små barn omkommer i brand men samma positiva utveckling kan inte ses för de äldre. LÄS MER

  3. 2. Risk of spontaneous fires at temporary storages sites for organic material, waste fuels and recyclables: Quantification and mitigation

    Författare :Muhammad Asim Ibrahim; William Hogland; Ghasem Najafpour; Linnéuniversitetet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; temporary storage; risk of fires; spontaneous ignition; biofuels; recyclables; waste fuels; Miljövetenskap; Environmental Science;

    Sammanfattning : Economic and environmental constraints have created increasing demand for (material and energy recovery) and recycling of waste generated from households, commercial and industrial activities. A wide variety of materials waiting for sorting, recovery, recycling and disposal are stored at temporary storage sites (TSS) where physical, biotic and abiotic processes can lead the stored material to spontaneous ignition.

  4. 3. Fire Spalling of Concrete : Theoretical and Experimental Studies

    Författare :Robert Jansson; Johan Silfwerbrand; Ulrich Diedrichs; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Fire spalling of concrete is not a new phenomenon. To some degree there has always been a risk during rapid heating of concrete. Therefore, to a certain degree the effect of fire spalling is included in the bank of data from fire tests and fires on which our understanding of the fire resistance of concrete is based. LÄS MER

  5. 4. Measurement of Self-Heating of Biomass Pellets using Isothermal Calorimetry

    Författare :Ida Larsson; Karin Granström; Anders Lönnermark; Per Blomqvist; Patrick van Hees; Karlstads universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; isothermal calorimetry; biomass pellets; wood pellets; self-heating; reactivity; screening test; isoterm kalorimetri; pellets; biomassa; självuppvärmning; reaktivitet; screeningtest; Miljö- och energisystem; Environmental and Energy Systems;

    Sammanfattning : Self-heating in storage facilities of biomass pellet can lead to spontaneous combustion. This has resulted in many fires over the years, causing both financial and environmental losses.In order to assess the risk for spontaneous combustion of biomass pellets during storage, it is important to know how prone the fuel is to self-heating, i.e. LÄS MER

  7. 5. Essays on Firms’ Hiring, Investment and Risk Management Decisions

    Författare :Emil Bustos; Handelshögskolan i Stockholm; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

    Sammanfattning : This thesis contains five self-contained chapters. In “The Effect of Centrally Bargained Wages on Firm Growth”, the author studies how firms adjust their hiring and investments in response to higher collectively bargained wage increases. Firms absorb labor cost shocks by increasing sales growth. LÄS MER
