  1. 11. Spectroscopic determination of stellar parameters to constrain atomic diffusion in the old open cluster M67

    Kandidat-uppsats, Uppsala universitet/Institutionen för fysik och astronomi

    Författare :Fabian Lundell; [2022]
    Nyckelord :;

    Sammanfattning : In an attempt to check published results on diffusion effects in M67 a non-LTE analysis is made on 28 high resolution FLAMES-UVES spectra of dwarfs and sub-giants around the turnoff point, where core hydrogen fusion halts. This analysis utilizes the software-suites LOTUS and iSpec to determine stellar parameters from equivalent-width measurements. LÄS MER

  2. 12. Korslimmat trä : Studie om delaminering vid brandexponering för olika brandskyddsbehandlingar

    Uppsats för yrkesexamina på grundnivå, Mälardalens universitet/Akademin för ekonomi, samhälle och teknik

    Författare :Vera Engvall; Zinar Zanasson; [2022]
    Nyckelord :Cross-laminated timber; delamination; charring carbonization ; surface requirements; Boverket s building regulations; PUR glue.; Korslimmat trä; delaminering; förkolning; ytskiktskrav; Boverkets byggregler; PUR-lim;

    Sammanfattning : Purpose: This work is based on the problem with the product cross-laminated timber and its properties in the event of fire. The reason for the problem is the glue used in the product and the lack of requirements for adhesion at high temperatures. Due to this, there is a risk of delamination in the event of a fire, i.e. LÄS MER

  3. 13. YTBEHANDLADE TRÄELEMENT : En studie av brandskydd, bärförmåga, pris och miljöpåverkan av ytbehandlade träelement.

    Uppsats för yrkesexamina på grundnivå, Mälardalens högskola/Akademin för ekonomi, samhälle och teknik

    Författare :Angelo Issa; Maher Machhadi; Mircea Barbu; [2021]
    Nyckelord :Timber; surface-treatment; fire-safety; load-bearing capacity; charring-rate; fire-retardant paint; fire-resistance; high-rise building.;

    Sammanfattning : The current Swedish building code (Boverkets Byggregler, BBR) is very strict regarding fire-safety in high-rise timber structures because of the heightened risk of fast flame spread or structural failure in case of fire. Fire safety solutions, that are used in timber structures must therefore be optimal to contain flames from spreading in the event of fire. LÄS MER

  4. 14. Pyromaner vs. Mordbrännare - Vem är det egentliga hotet?

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Juridiska institutionen; Lunds universitet/Juridiska fakulteten

    Författare :Emily Rasmussen; [2021]
    Nyckelord :Straffrätt; Criminal Law; Pyromani; Pyromania; Mordbrännare; Mordbrand; Gryningspyromanen; Law and Political Science;

    Sammanfattning : It is burning, the flames have spread to the roof and once again, terror plagues the people of Sweden. Gryningspyromanen has just left the entrance of Bollhusgatan 8 in Ystad and the police are right behind him. This time, the evidence will be sufficient for a conviction. LÄS MER

  5. 15. Detection of nitrous oxide through IR-DFWM in gas flows with future application in ammonia flames

    Master-uppsats, Lunds universitet/Förbränningsfysik; Lunds universitet/Fysiska institutionen

    Författare :Martin Passad; [2021]
    Nyckelord :Physics; Optics; Lasers; Environment; Hydrogen; Hydrogen Energy; Ammonia Energy; DFWM; Ammonia; Nitrous Oxide; Ammonia Flame; Ammonia Combustion; Physics and Astronomy;

    Sammanfattning : This thesis report on an investigation into the applicability of mid-infrared degenerate four-wave mixing (IR-DWFM) as a method to detect N\(_2\)O in ammonia flames. DFWM has previously been used for concentration measurements on other molecules, but has never, to the author's knowledge, been applied to measure N\(_2\)O in ammonia flames before. LÄS MER
