  1. 1. Vibrational signals as indicators of soil fauna health? : A novel approach to environmental monitoring of ants

    University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Author : Joel Fransson Forsberg; [2023]
    Keywords : Vibrations; Formica ants; Vibrometer; Vibrational signals; Imidacloprid; Before-After-Control-Impact;

    Abstract : Soil fauna provides processes of crucial importance for ecosystem functions, but our ability to observe their actions often depend on destructive methods where the integrity of the studied environment (the soil) is compromised. In this study, I develop and test a new generation of environmental monitoring tools that utilize vibrations made by soil macrofauna to inform about their performance and health. READ MORE

  5. 4. 3D Knit fabrics : optimizing spacer knit fabrics for comfort and breathability in infant products

    University essay from Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Author : Julia Svensson; Hanna Halldorf; [2023]
    Keywords : Spacer fabric; knitting; warp knit; circular knit; textile testing; ProCad Warpknit; infant product; comfort; mechanical properties.;

    Abstract : In this study we looked into an existing textile baby stroller seat and investigated whether there can be any advantage in changing the material to a spacer fabric from perspectives such as functionality, comfort, and sustainability. The subject of 3D knitting, and advanced knitting is being researched more and more because of its versatility in producing and changing parameters of knitted high quality products, but there is a lack of studies done on comfort for children when it comes to knitted spacer fabrics and not many studies have been done on spacer fabrics used for baby seats in strollers or other types of seats for children.
