  1. 6. Managing the implementation of sustainable polyurethane (PU) coating for functional wear

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

    Författare :Zarin Tasnime; Christine Buckley; [2023]
    Nyckelord :PU coating; Water resistance; Sustainability; Textile management; Key factors;

    Sammanfattning : The purpose of this study is to explore the practical implementation of a commercially available sustainable alternative to conventional polyurethane (PU) textile coating for functional outerwear garments with protection from rain and snow. In addition, this study will identify the key consideration areas which should be taken into account during the managerial decision-making process of implementing the sustainable PU coating. LÄS MER

  3. 7. Analys av klimatpåverkan och lokaliseringsbeslut för en Factory-In-A-Box produktionsanläggning

    Kandidat-uppsats, KTH/Produktionsutveckling

    Författare :Yiming Alex Ding; Liuyu Qian; [2023]
    Nyckelord :Factory-In-A-Box; Lifecycle Analysis; Climate impact; production; disposable plastic products; Factory-In-A-Box; Livscykelanalys; klimatpåverkan; produktion; engångs plastprodukter;

    Sammanfattning : Syftet med denna studie var att analysera lokaliseringsbeslut för en Factory-In-A-Box (FIAB) produktionsanläggning med fokus på dess klimatpåverkan genom användning av livscykelanalys (LCA). En FIAB produktionsanläggning användes som ett exempel för att utföra analysen. LÄS MER

  4. 8. Evaluation of the Weather Resistance of Ram-Air Kites Used in Airborne Wind Energy Systems

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

    Författare :Johanna Désirée Ambs; [2023]
    Nyckelord :Weathering Resistance; Coated Textiles; Ram-air Kite; Airborne Wind Energy;

    Sammanfattning : Airborne Wind Energy is an emerging technology that harnesses the power of the wind by using tethered wings. Among the flying devices are ram-air wings made from coated textiles that utilize dynamic pressure to gain their shape. LÄS MER

  5. 9. 3D printer in dosimetry and mammography – designing and testing an OSL dosemeter holder and a low contrast-detail phantom

    Master-uppsats, Lunds universitet/Sjukhusfysikerutbildningen

    Författare :Måns Boll; [2022]
    Nyckelord :Medicine and Health Sciences;

    Sammanfattning : Introduction: Today, 3D printing is a versatile tool used in a wide range of fields. With the advent of more cost-effective fused deposition modelling (FDM) 3D printing technologies it is time to investi- gate what such a 3D printer has to offer in radiation science applications.

  7. 10. Define optimum process conditions to produce CO2 adsorbents from pur materials

    M1-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Författare :Daniel Pantzar; Anton Coates; [2022]
    Nyckelord :Carbon capture and storage; Adsorbent; Chemical activation;

    Sammanfattning : The Carbon Capture and Storage method has been acknowledged for the capabilities of reducing up to 20% CO2 emissions. Development of porous carbon materials prepared from polyurethane foam adsorbent were investigated for capture of CO2. In this thesis work, the carbon material was chemically activated through the direct and indirect methods. LÄS MER
