  1. 6. A Geophysical Survey of Northern Utö

    University essay from Stockholms universitet/Institutionen för geologiska vetenskaper

    Author : Nicole Flanders; [2023]
    Keywords : ;

    Abstract : A geophysical investigation on the northern part of Utö was carried out between 2020 and 2021 to asses the extent of the iron ore (BIFs) and the iron bearing sulfides that have been surveyed and mined in the past. The survey using analog field equipment combined magnetometry, gravimetry, susceptibility, leveling, density, and thin-section microscopy. READ MORE

  3. 7. Formulation and characterisation of novel edible-packaging for fruits and vegetables

    University essay from Lunds universitet/Livsmedelsteknik och nutrition (master)

    Author : Lola Sutton; Katerina Papa; [2023]
    Keywords : algae; edible packaging; carrageenan; cucumber; REL; oxidative stress; antioxidants; food engineering; Technology and Engineering;

    Abstract : This master's thesis investigated the potential of algae raw materials, specifically k-carrageenan and to a lesser extent alginate, as film-forming ingredients for the development of a novel edible packaging solutions. The project involved the testing and characterisation of several active ingredients of algal and plant origins both as extracts and as ingredients in films. READ MORE

  4. 8. Feasibility Study on Additive Manufacturing of Copper Windings using Electron Beam Melting

    University essay from KTH/Produktionsutveckling

    Author : Marilena Wiele; Murad Abulawi; [2023]

  5. 9. Developing a Test Method to Evaluate the Blackout Effect of Uncoated Curtains at Varying Angles

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

    Author : Sara Muminovic; Christina Lindén; [2023]
    Keywords : Blackout effect; blackout curtain; uncoated woven curtains; angle interval; light transmission; light box; light diffuser; microscopic image analysis;

    Abstract : This study aimed to explore the integration of varying angles in small-scale measurements and assess the light transmission performance of uncoated curtains. A total of four curtains were evaluated: blackout curtain samples 1 and 2 had a weft satin structure, while daytime curtain samples 3 and 4 consisted of a twill structure. READ MORE

  6. 10. Wound Treatment : An overview and initial investigation of wound care and bioactive materials

    University essay from Uppsala universitet/Tillämpad materialvetenskap

    Author : Louise Ringholm; [2023]
    Keywords : Wound treatment; wound care; bioactive materials; calcium silicate;

    Abstract : Wound care is a field with many treatment methods and products on the market. The healing period varies, some wounds become difficult to heal and chronic, in many cases a connection can be drawn to underlying diseases. Diabetes is a disease that could cause foot ulcers that are difficult to heal. READ MORE
