  1. 1. Recovery of Dialcohol Cellulose using Micro- and Ultrafiltration Processes

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Lina Näslund; Gabriella Petersson; [2023]
    Nyckelord :Membrane filtration; Ultrafiltration; Microfiltration; Dialcohol cellulose; DAC; Bioplastics; Chemical engineering; Process design; Technology and Engineering;

    Sammanfattning : The waste management and production of plastic play a concerning part in global warming and continues to have a negative effect on the environment. A promising strategy to address this challenge is to develop new sustainable materials, to replace current fossil-based plastics. LÄS MER

  3. 2. Modelling masonry spires : An investigation

    Master-uppsats, KTH/Betongbyggnad

    Författare :Dennis Lillemo; [2021]
    Nyckelord :Abaqus; Concrete damage plasticity; Finite element method; Limit analysis; Macro-modelling; Masonry; Masonry spire; Nonlinear material; Salisbury Cathedral; Abaqus; Concrete damage plasticity; Finita elementmetoden; Gränsanalys; Makromodellering; Murverk; Murad tornspira; Icke-linjärt material; Katedralen i Salisbury;

    Sammanfattning : Masonry spires are a typical part of church architecture. Since it is rare that masonry is used as a load-bearing material in the western world today, it is important to maintain and increase the knowledge of modelling masonry structures both from a maintenance point of view and to build new masonry structures.

  4. 3. Bakteriell Cellulosa-tillverkning från Melass genom Kombucha-fermentering

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

    Författare :Adina Engström; [2019]
    Nyckelord :Bacterial Cellulose; Molasses; Kombucha;

    Sammanfattning : As the global plastic consumption is increasing, an innovative substitute for petroleum-based product must be developed towards a more sustainable society. Cellulose is the most abundant biopolymer on earth having potential because of its biodegradability and is produced from renewable resources. LÄS MER

  5. 4. Shelf life of fresh-cut fruits and salad leaves treated with Pulsed Electric Field (PEF)

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

    Författare :Chandan Soni; [2019]
    Nyckelord :PEF; pulsed electric field; reversible electroporation; calorimeter; metabolic rate; shelf life; fresh commodities; food engineering; livsmedelsteknik; Agriculture and Food Sciences; Technology and Engineering;

    Sammanfattning : Application of Pulsed Electric Field (PEF) treatment on five fresh commodities was analysed for the changes in the metabolic and physiological effects on their shelf life. Treatment parameters were optimised in order to achieve uniform electroporation on the samples, which was analysed by Propidium Iodide staining for the leaf samples. LÄS MER

  7. 5. Real-Time Monitoring of Neurovascular Cells

    Master-uppsats, KTH/Mikro- och nanosystemteknik

    Författare :Vladimir Banovic; [2018]
    Nyckelord :;

    Sammanfattning : Organs-on-a-chip devices are perfused cell culture systems aimed at creating the minimal functional unit of an organ - suchas the neurovascular unit (NVU) of the brain. NVU-on-a-chip platforms can provide an effective framework for studyingcentral nervous system physiology, disease etiology and provide a mean for drug development. LÄS MER
