  1. 1. Production of textile fibres from filamentous fungi grown on apple pomace : invertase pre-treatment

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

    Författare :Sofia Berg; [2023]
    Nyckelord :apple pomace; invertase; fibres; filamentous fungi; dry gel spinning;

    Sammanfattning : In this work Rhizopus Delemar was grown on an apple pomace medium, a waste product from the juice industry. The apple pomace was pre-treated with the enzyme invertase to hydrolyse the sucrose available in the waste to glucose and fructose, which are digestible by the fungus. LÄS MER

  3. 2. Wet Spinning of Cellulose-Lignin Precursor for Carbon Fibers : Effect of Coagulation Bath Composition & Spin Finish

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Tillämpad mekanik

    Författare :Julia Sundmark; [2023]
    Nyckelord :Carbon fiber; Cold alkali; Cold NaOH; lignin; cellulose; wet spinning; Kolfiber; kallalkali; lignin; cellulosa; våtspinning;

    Sammanfattning : Carbon fibers (CF) are a material with a composition of over 90% carbon, which has high mechanical properties and low density. This unique combination of properties makes it requirable in applications such as vehicles, aerospace, wind power, and space industries. Commercially made CF are made using the fossil raw material polyacrylonitrile (PAN). LÄS MER

  4. 3. Error propagation in nuclear models

    Kandidat-uppsats, Lunds universitet/Matematisk fysik; Lunds universitet/Fysiska institutionen

    Författare :Artis Mucenieks; [2023]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : In this thesis we perform error analysis of a nuclear model based on density-functional theory developed in Lund. The Lund model allows us to perform calculations of nuclear spectra more efficiently by constructing a simple effective Hamiltonian reproducing the quadrupole deformation and pairing interaction strength parameters of a spherical Hartree-Fock reference functional.

  5. 4. Evaluation of Numerically Developed Models of an ECB for Estimating the Braking Torque on the SkiCrosser

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Filip Andersson; William Marin; [2023]
    Nyckelord :;

    Sammanfattning : Cross-country skiing is a popular method of exercising that builds strength, stamina and engages the entire body. As cross-country skiing requires snow to be present, it is typically only performed during the winter, resulting in a rather limited way of exercising. LÄS MER

  7. 5. Förbättrad design av en tittlåda för att skatta hörsel hos yngre barn

    Kandidat-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknik

    Författare :Ebba Wallenberg; Agnes Möller; [2023]
    Nyckelord :Tittlåda; audiometri; audiometry; VRA; Visual Reinforcement Audiometry; audiologi; visuell belöningsaudiometri; Technology and Engineering;

    Sammanfattning : In order for the central auditory organs and auditory cortex to develop correctly, auditory stimulation is required from an early age. Due to this, it is vital to identify children with a hearing impairment as quickly as possible. LÄS MER
