  1. 1. Qualitative Analysis of Chlorinated Paraffins in Recycled Plastics

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

    Författare :Solal GAUDIN; [2023]
    Nyckelord :Short chain Chlorinated Paraffins SCCP Medium chain Chlorinated Paraffins MCCP Long chain Chlorinated Paraffins LCCP Recycled plastics Qualitative analysis Bioaccumulation Long range transport Gas Chromatography – Mass spectrometry;

    Sammanfattning : Described in many studies as dangerous for the environment and potentially carcinogenic for humans, Chlorinated Paraffins (CPs) are easily widespread due to their substantial production and use in different products. Previous studies reported the presence of CPs in different plastic polymers. LÄS MER

  3. 2. Solutions for presence detection in an intercom door station

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Industriell elektroteknik och automation

  4. 3. Robot arm with object detection for waste management

    Kandidat-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Albin Gunnarsson; Dag Ehlin; [2023]
    Nyckelord :Mechatronics; Raspberry Pi; stepper motors; cylindrical robot arm; machine learning;

    Sammanfattning : Recycling is becoming more crucial due to the fast pace of consumerism. This thesis explores how well a robot arm, with three degrees of freedom, can be implemented to give an autonomous recycling process. After the prototyping phase it was found that a cylindrical robot arm was best suited for the project. LÄS MER

  5. 4. Making nets more acoustically visible : Floats as passive mitigation measures to reduce bycatch of harbour porpoise (Phocoena phocoena) in gillnets

    Master-uppsats, SLU/Dept. Of Aquatic Resources

    Författare :Frida Rosshagen; [2023]
    Nyckelord :toothed whales; harbour porpoise; Phocoena phocoena; incidental capture; bycatch; fisheries; fishing gear; ; gillnet; mitigation; reduction; low-cost; passive acoustic reflector; float;

    Sammanfattning : Incidental capture in fishing gear is today affecting at least 112 marine mammal species worldwide and for many smaller toothed whale species (Odontocete), gillnets are considered to be the largest problem. Although some effective mitigation measures exists, these are often context specific and many might be hard to implement due to reasons such as high costs and maintenance. LÄS MER

  7. 5. Prolongation of shelf life of minimally processed spinach by combining vacuum impregnation and electric field treatments

    Master-uppsats, Lunds universitet/Livsmedelsteknik och nutrition (master)

    Författare :Sophia Leffler; [2022]
    Nyckelord :spinach; pulsed electric field; moderate electric field; reversible electroporation; vacuum impregnation; shelf life; metabolic activity; respiration; food engineering; Agriculture and Food Sciences;

    Sammanfattning : A continuous growth of the world population raises the importance of preserving food resources while maintaining their nutrient value. Leafy vegetables such as spinach are a food category which decay quickly, and a large amount ends up as food waste. LÄS MER
