  1. 16. Formulation of nanoemulsions stabilized by cellulose nanocrystals

    Master-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Marco Maccagno; [2020]
    Nyckelord :nanocellulose; hydroxypropyl methilcellulose; Pickering emulsions; microfluidization; drug delivery; nanocellulosa; hydroxipropylmetylcellulosa; Pickering emulsioner; microfluidization; drogleverans;

    Sammanfattning : Cellulose nanocrystals (CNCs) are bio-based nanoparticles with the ability to stabilize oil and water emulsions thanks to their intermediate wettability and nanometric size. These and other types of particle-stabilized emulsions, commonly referred to as Pickering emulsions, are of great academic and industrial interest due to their superior stability against drop coalescence compared to classical surfactant-stabilized emulsions.

  3. 17. Gallringens effekter på botten- och fältskikt i grandominerad produktionsskog : en studie av hur störning kan påverka β-diversitet i Norrland och Svealand

    Kandidat-uppsats, SLU/Dept. of Wildlife, Fish and Environmental Studies

    Författare :William Jaktén Langert; Andreas Widell; [2020]
    Nyckelord :biodiversitet; bottenskikt; fältskikt; störning; gallring; boreal skog;

    Sammanfattning : Den boreala skogens beståndsstruktur har historiskt primärt präglats av brand, vilket skapat en flerskiktad beståndsstruktur. Störning är därför en avgörande faktor för artmångfald i dessa ekosystem. LÄS MER

  4. 18. Speech Emotion Recognition from Raw Audio using Deep Learning

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Jonathan Rintala; [2020]
    Nyckelord :Speech Emotion Recognition; Feature Learning; Deep Learning; Audio; SER; CNN; LSTM; Känsloigenkänning; Djupinlärning; Ljud; SER; CNN; LSTM;

    Sammanfattning : Traditionally, in Speech Emotion Recognition, models require a large number of manually engineered features and intermediate representations such as spectrograms for training. However, to hand-engineer such features often requires both expert domain knowledge and resources. LÄS MER

  5. 19. Investigation of Governing Physics in a PEM Electrolyzer

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Kian Hajireza; [2020]
    Nyckelord :chemical engineering; electrochemistry; polymer-electrolyte membrane; electrolysis; hydrogen production; COMSOL; physics-based mode; multiphase transport; kemiteknik; Technology and Engineering;

    Sammanfattning : Hydrogen gas is an energy source that has an energy density (per mass) that is three times as large than the energy density of natural gas. This qualifies hydrogen gas as a prime candidate for the fuel of tomorrow. One of the main research areas for hydrogen include the production of it as there are a vast amount of methods of hydrogen production. LÄS MER

  7. 20. Snow insulation effects across the Arctic : evaluating a revised snow module in LPJ-GUESS

    Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Alexandra Pongrácz; [2019]
    Nyckelord :active layer depth; Arctic; LPJ-GUESS; snow; soil temperature; Earth and Environmental Sciences;

    Sammanfattning : The effect of future changes in temperature and precipitation patterns on arctic ecosystem functioning is often assessed using state-of-the-art ecosystem models. Many models however lack detailed representation of wintertime processes, as pointed out by recent studies (Wang et al. 2016, Slater and Lawrence 2013). LÄS MER
