    Sammanfattning : Energiomställning och globala mål ställer allt högre krav på länder, organisationer och olikabranscher, inte minst byggbranschen. En metod för att minska belastningen på det nationellaelnätet och göra fastigheter mindre beroende av de stora fluktuationerna i energipriserna ärsolcellsanläggningar. LÄS MER

  3. 2. ENVIRONMENTAL AND ECONOMIC IMPACT OF USING RECYCLED MATERIALS IN WALL INSULATION : Energy management for sustainable cities, ETC building project.

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

    Författare :Karima Alothman alsaghir; [2023]
    Nyckelord :Residual buildings; Walls insulation; Recycled materials; Thermal conductivity; IDAICE software; Climate-smart building; Thermo-environmental assessment; Thermo-economic assessment.;

    Sammanfattning : Recycled material has attracted extensive interest due to its positive impact on decarbonization in the building sector. At the same time, utilizing these materials is limited. The main objective of this degree project is to provide a better understanding of recycled materials and their role in environmental and economic aspects.

  4. 3. 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.

  5. 4. Investigation of the impact of different sugar compositions on the moisture absorption of hard candy when exposed to a humid environment

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

    Författare :Gila van den Eijnde; [2023]
    Nyckelord :Hard candy; Sugar composition; Hygroscopicity; Moisture absorption; Shelf life; Product stability; Food technology; Technology and Engineering;

    Sammanfattning : Hard candy is hygroscopic, implying that hard candy readily absorbs moisture from the environment, resulting in adverse changes in the texture and appearance of the candy. This thesis investigates the impact of different sugar compositions on the moisture absorption of hard candy when exposed to a humid environment. LÄS MER

  7. 5. Moisture Transport in PA6

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

    Författare :Emanuel Markström; [2022]
    Nyckelord :Technology and Engineering;

    Sammanfattning : Polyamide 6 (PA6) is known to absorb water from its environment due to its chemical structure. The water absorption leads to changes in the mechanical properties as well as an increase in volume (swelling) of the polyamide. LÄS MER
