  1. 1. Behavioural response in pigs at gas stunning in foam

    Master-uppsats, SLU/Dept. of Animal Environment and Health

    Författare :Madeleine Persson; [2024]
    Nyckelord :stunning methods; slaughter; animal welfare; carbon dioxide; high-expansion foam; nitrogen; argon;

    Sammanfattning : There are several stunning methods used for the commercial slaughter of pigs. The two most common are electric stunning and stunning with carbon dioxide gas. It has been shown that there are several problems related to animal welfare in the stunning methods used today in commercial slaughter. LÄS MER

  3. 2. Tomography-based Micromechanical Analysis of Novel Composite Material

    Master-uppsats, KTH/Hållfasthetslära

    Författare :Mattias Grankvist; [2023]
    Nyckelord :paper mechanics; micro mechanics; numerical analysis; tomography; foam forming; density profile; pappersmekanik; mikromekanik; numerisk analys; tomografi; skumformning; densitetsprofil;

    Sammanfattning : This study explores the performance of porous Paptic paper materials composed of a mixture of softwood and lyocell fibers. The investigation involves laboratory experiments and numerical simulations to analyse the impact of various parameters on the paper's characteristics. LÄS MER

  4. 3. Friend or foam? Improved methods for stunning of pigs with foam : effects of repetition and scent on pig reaction to foam

    Uppsats för yrkesexamina på avancerad nivå, SLU/Dept. of Animal Environment and Health

    Författare :Miranda Blad; [2022]
    Nyckelord :pig; behaviour; stunning; foam; smell; scent; fear assessment; animal welfare;

    Sammanfattning : There are several methods available for stunning of pigs before slaughter, but the most frequently used at larger abattoirs are electricity and CO2. There are advantages and disadvantages with both methods. As there is no method that does not have major animal welfare drawbacks. LÄS MER

  5. 4. Översilningsytors potential att rena lakvatten från PFAS

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Emma Larsson; [2020]
    Nyckelord :PFAS; leachate; overland flow area; waste facility; waste; landfill; PFAS; lakvatten; översilningsytor; avfallsanläggning; avfall; deponi;

    Sammanfattning : Poly- and perfluorinated alkyl substances (PFASs) is a group of more than 5000 different substances, of which all consist of a fluorinated carbon chain resulting in a strong bond. Most of these substances are shown to be persistent, bioaccumulative and toxic for both humans and the environment. LÄS MER

  7. 5. Evaluation of drag estimation methods for ship hulls

    Master-uppsats, KTH/Mekanik

    Författare :Hampus Tober; [2020]
    Nyckelord :;

    Sammanfattning : This study aims to evaluate to which degree CFD can complement traditional towing-tank experiments, and to develop a computationally cheap and robust methodology for these type of simulations. Two radically different surface ship hulls were chosen for the trials: a capesize bulk carrier and a fast displacement hull. LÄS MER
