  1. 21. Temperature dependent preening behaviour in common guillemots Uria aalge

    Kandidat-uppsats, SLU/Dept. Of Aquatic Resources

    Författare :Saga-Savanna Kynman; [2023]
    Nyckelord :common guillemot; common murre; seabirds; Stora Karlsö; heatstress; temperature; preening; allopreening;

    Sammanfattning : As global temperature increase, new thermal conditions may challenge the physiological limits of endotherms. Examining the direct effects of extreme temperatures is an important component in understanding how these physiological limits may impact an organism’s behaviour, breeding success and survival.

  3. 22. 3D Knit fabrics : optimizing spacer knit fabrics for comfort and breathability in infant products

    Kandidat-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomi

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

    Sammanfattning : 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.

  4. 23. Automated High-Temperature Pressure Sensor Verification and Characterization

    Master-uppsats, Linköpings universitet/Institutionen för systemteknik

    Författare :Algirdas Bartkevicius; [2023]
    Nyckelord :Pressure sensor; sensor verification; sensor characterization; piezoelectric sensor; dynamic pressure sensor;

    Sammanfattning : Gas turbines are widely used in power generation. Monitoring pressure variations in the combustion chamber allows for real-time assessment of the turbines performance, and can be used to optimize combustion processes, leading to reduced emissions. LÄS MER

  5. 24. Demand controlled ventilation : Impact on energy use and indoor environmental quality

    Master-uppsats, Mälardalens universitet/Akademin för ekonomi, samhälle och teknik

    Författare :Therese Ottosson; [2023]
    Nyckelord :;

    Sammanfattning : European buildings account for a significant share of the energy-related emissions in Europe. Addressing the increasing energy use and its contribution to greenhouse gases (GHG) is internationally recognized as crucial, and emissions must be halted. LÄS MER

  7. 25. The Development and Testing of Low-Cost Heat Transfer Enhancements for Solar Dryers

    Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

    Författare :Hoda Mahmoodi; [2023]
    Nyckelord :Solar dryer; Bhutan; Drying rate; Solar absorber; Technology and Engineering;

    Sammanfattning : In the mountainous regions of Bhutan and Nepal, post-harvest losses cause significant challenges for producers. Open air sun drying is usually used by farmers to preserve their produce. There are many disadvantages to this method. LÄS MER
