  1. 21. Snow depth measurements and predictions : Reducing environmental impact for artificial grass pitches at snowfall

    University essay from Linnéuniversitetet/Institutionen för datavetenskap och medieteknik (DM)

    Author : Findlay Forsblom; Lars Petter Ulvatne; [2020]
    Keywords : artificial grass; rubber granulate pollution; snow depth measurement; snow level prediction; temperature index; energy index; energy balance model; machine learning; python; random forest; ultrasonic sensor; infrared sensor; lorawan; pycom lopy4; micro python; arduino uno; web application; javascript; node.js;

    Abstract : Rubber granulates, used at artificial grass pitches, pose a threat to the environment when leaking into the nature. As the granulates leak to the environment through rain water and snow clearances, they can be transported by rivers and later on end up in the marine life. Therefore, reducing the snow clearances to its minimum is of importance. READ MORE

  5. 24. Transcriptomic isolation and sequencing of the freshwater mussel Anodonta anatina : A pilot study and method development

    University essay from Högskolan i Skövde/Institutionen för biovetenskap

    Author : Johan Bergholm; [2019]
    Keywords : ;

    Abstract : The freshwater mussel Anodonta anatina is a common mollusc found in rivers and lakes in Europe. Due to its lifestyle as an immobile substrate filter feeder, it is only exposed to pollutions which passes by it, thus the mussels are viable to be used as a bioindicator for the analysis of local aquatic health.
