  1. 1. Mikroplaster i damm från ridunderlag - pilotstudie

    Kandidat-uppsats, SLU/Dept. of Anatomy, Physiology and Biochemistry

    Författare :Niklas Nilsson; [2023]
    Nyckelord :fibersand; underlag; häst; nedbrytning;

    Sammanfattning : Ridsporten är en av de största ungdomsidrotterna inom Sverige. År 2018 beräknades det att cirka 5 miljoner ridtimmar genomförs på landets ridskolor årligen. På grund av Sveriges klimat spenderas mycket av denna tid inom ridhus. LÄS MER

  3. 2. Jämförelse av mattor för vibrationsmatare med hjälp av försöksplanering

    Kandidat-uppsats,

    Författare :Simon Johannesson; Shukrullah Mohammad Ishaq; [2023]
    Nyckelord :Design of experiments; DoE; vibratory feeders; Design-Expert; response surface; Optimal design; Försöksplanering; Statistisk försöksplanering; vibrationsmatare; responsyta;

    Sammanfattning : Detab is a company in Jönköping that develops systems for feeding parts for robots and packaging processes. To control the flow of parts on their vibratory feeders, Detab uses different carpets with angled straws. The two mainly used carpets have been discontinued and must now be replaced. LÄS MER

  4. 3. Mechanical properties of compression moulded fibre composite sheets

    Master-uppsats, KTH/Hållfasthetslära

  5. 4. Structure–Acoustic Interaction Between Vehicle Floor Panels and Carpets – Numerical Simulations and Measurements

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Byggnadsmekanik; Lunds universitet/Institutionen för byggvetenskaper

    Författare :Aya Karim; Jesper Brindhag; [2021]
    Nyckelord :Structure-acoustic; Acoustic; Dynamic; Floor panels; Interior carpets; NVH; FEM; Finite element; PEM; Porous elastic; Noise radiation; Interior-noise; Vehicles; Vibration; Structure-borne noise; Technology and Engineering;

    Sammanfattning : An attribute that is highly valued amongst vehicle customers is low interior-noise levels when a vehicle is in use. Much of the interior-noise is believed to stem from the vibrations of floor panels in vehicles. LÄS MER

  7. 5. Modelling Competitive Sorption of Per- and Polyfluoroalkyl Substances (PFASs) to Soil and Sorbents

    Master-uppsats, Uppsala universitet/Luft-, vatten- och landskapslära

    Författare :Linnea Georgii; [2021]
    Nyckelord :PFAS; modelling; competitive sorption; adsorption; isotherms; PFAS; modellering; konkurrenseffekter; adsorption; isotermer;

    Sammanfattning : Per- and polyfluoroalkyl substances (PFASs) have become contaminants of increasing concern to society due to the contamination of drinking water and the ecosystem. A better understanding of the sorption and transport of PFASs in soil systems is urgently needed, however there have been few studies dedicated to investigating competitive sorption among PFASs, and there is no available model to model such effects.
