  1. 1. Utvärdering av tunnelbrandsmodeller

    Kandidat-uppsats, Lunds universitet/Avdelningen för Brandteknik

    Författare :Johanna Gondinger; Alva Larsson; [2024]
    Nyckelord :Tunnelbränder; FDS; handberäkning; branddynamik; brandexperiment Tunnel fires; CFD; hand calculations; fire dynamics; fire experiment; Technology and Engineering;

    Sammanfattning : The purpose of this study was to investigate the predictive capabilities of hand-calculation methods and simulations using FDS in understanding the behavior of a tunnel fire in terms of temperature and incident radiation. Additionally, the study aimed to examine the repeatability of a large-scale fire experiment. LÄS MER

  3. 2. Sustainable food packaging based on polyhydroxyalkanoate

    Master-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Författare :Safana Al-Ashor; [2024]
    Nyckelord :Biopolymers; Sustainable food packaging; Circular economy; Biobased and biodegradable materials; Food packaging; Processing technologies; Food quality; Shelf-life;

    Sammanfattning : The Norwegian Food Research Institute (Nofima) and the University of Borås worked together to develop this project. The commonly used packaging materials pose a serious threat to the environment, as they are produced from nonrenewable crude oil and cannot decompose naturally. LÄS MER

  4. 3. Prospects for a Free Electron Laser at the FemtoMAX Beamline

    Kandidat-uppsats, Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

    Författare :Johan Holmberg; [2024]
    Nyckelord :Free Electron Lasers; FEL; synchrotron radiation; MAX IV; FemtoMAX; GENESIS 1.3; XFEL; X-rays; soft X-rays; Physics and Astronomy;

    Sammanfattning : A Free Electron Laser (FEL), is a device that generates extremely coherent and brilliant radiation using electrons accelerated to relativistic velocities in a particle accelerator. The process utilises similar equipment to what is used at a synchrotron source like MAX IV, but in addition there is an interaction between the relativistic electron beam and the generated radiation to achieve an exponential growth in radiation intensity.

  5. 4. Product development of hand-held scooping utensil for the pharmaceutical industry

    Master-uppsats, KTH/Ergonomi

    Författare :Josefin Kruse; [2024]
    Nyckelord :;

    Sammanfattning : Musculoskeletal disorders (MSDs) are one of the most common groups of work-related illnesses. At PET Dispensing, AstraZeneca Södertälje, several MSDs had been linked to a specific scooping utensil made of stainless steel. LÄS MER

  7. 5. Jetbrandtester och vätgas : En litteratur- och intervjustudie om försök med vätgasjetflammor

    Uppsats för yrkesexamina på grundnivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Författare :Nils Stridsberg; [2024]
    Nyckelord :Hydrogen; jet flames; rescue service; standards; jet fire testing; jet fires; Vätgas; jetflammor; räddningstjänst; standarder; jetbrandtester; jetbränder;

    Sammanfattning : Vätgas är en energibärare som kan vara en av pusselbitarna i omställningen till en mer klimatneutral värld. Infrastrukturen byggs ut, industrin växer och vätgasfordon blir vanligare. LÄS MER
