  1. 11. Optimization of solid-phase extraction (SPE) as sample preparation for oil samples in forensic investigations.

    Kandidat-uppsats, Örebro universitet/Institutionen för naturvetenskap och teknik

    Författare :Aamanda Chang; [2021]
    Nyckelord :Solid-phase extraction SPE ; heavy fuel oil HFO ; fingerprint; polycyclic aromatic hydrocarbons PAHs ; biomarkers.;

    Sammanfattning : Oil spills, especially in water have happened throughout the years. The consequences from this kind of incident have always been a threat to marine life and take a lot of money and time to clean up. LÄS MER

  3. 12. Building with pollution

    Master-uppsats, Lunds universitet/Institutionen för arkitektur och byggd miljö

    Författare :Zornitsa Hristova Kovacheva; [2021]
    Nyckelord :Arts and Architecture;

    Sammanfattning : Black carbon is an ever-growing global problem and one of the most important environmental issues of this generation. Black carbon, also known as soot, is a highly polluting substance and it is the second-largest polluter after carbon dioxide. LÄS MER

  4. 13. A Comparison Between FDS and the Multi-Zone Fire Model Regarding Gas Temperature and Visibility in Enclosure Fires

    Kandidat-uppsats, Lunds universitet/Avdelningen för Brandteknik

    Författare :Benjamin Waldeck; [2020]
    Nyckelord :Enclosure fire; FDS; Multi-Zone Fire Model; gas temperature; Visibility; Technology and Engineering;

    Sammanfattning : When designing large buildings with complex geometry there is often a need for performance-based design and the use of computer models. CFD models like FDS that are available and validated for this purpose are typically time consuming and require large amounts of computing power. LÄS MER

  5. 14. Raman Spectroscopy for Characterizing Porous carbon

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

    Författare :Rima Zuriah Amdani; [2020]
    Nyckelord :Raman Spectroscopy; Porous Carbon; Biochar; Carbonization; Aromaticity; Physics and Astronomy; Technology and Engineering; Chemistry;

    Sammanfattning : Porous carbon obtained from low cost and abundant biomass has gained attention as renewable material feedstock. In this study, porous carbon biochar produced through pyrolysis was investigated by Raman spectroscopy to disclose the structural properties. LÄS MER

  7. 15. Application of mass defect filtering and statistical analysis for non-target data mining of gas and soot data from a study testing different firefighting methods

    Master-uppsats, Örebro universitet/Institutionen för naturvetenskap och teknik

    Författare :Danielle Ydstål; [2020]
    Nyckelord :;

    Sammanfattning : Due to the high temperatures during a fire event, a large variety of compounds are formed or released from burning materials, all of which have a varying degree of environmental effects. In an incidental fire there are several variables that are important for which and how much combustion products that are formed, including the burning material, ventilation (presence of air), and temperature.
