  1. 21. Effects of soil factors on pioneer bryophyte species composition

    Master-uppsats, Lunds universitet/Examensarbeten i biologi

    Författare :Dora Mijić; [2023]
    Nyckelord :Biology and Life Sciences;

    Sammanfattning : Bryophytes play a significant role in various ecological processes, including soil succession and colonization after disturbances. Although they are commonly believed to take up nutrients from soil solutions rather than the soil itself, the influence of soil on their growth and distribution is evident from previous studies.

    Sammanfattning : In face of climate change, Europe and other global actors are in the process of transitioning to carbon-neutral economies, aiming to phase out of fossil fuels and power industries with renewable energies. Hydrogen is going to play a crucial role in the transition, replacing fossil fuels in hard-to-decarbonize industries and acting as energy carrier and energy storage for renewable electricity.

    Sammanfattning : Background: For decades, aviation has been an important part of society and with its growth comes the increased environmental impact and the challenge to reduce this adversary effect and move towards sustainability. Objective: Find out how airlines can reduce their emissions and become more sustainable. LÄS MER

  5. 24. Biocatalysis in Pickering emulsions

    Master-uppsats, Lunds universitet/Bioteknik (master); Lunds universitet/Bioteknik (CI)

    Författare :Christine Vera Isabel Schmidt; [2023]
    Nyckelord :Enzymes; Pickering emulsion; Amine Transaminases; Green Chemistry; Stereoselectivity; Biotechnology; Biology and Life Sciences;

    Sammanfattning : Employing enzymes as catalysts in the production of chiral amines that are both used as building blocks and active pharmaceutical ingredients might be promising due to milder reaction conditions compared to non-biological catalysts, exclusion of heavy metals, high selectivity towards substrates and precision in chirality of the products. Transaminases are attractive for the use in this process. LÄS MER

  7. 25. Nursing interventions for patients with stroke : A descriptive review

    Kandidat-uppsats, Högskolan i Gävle/Avdelningen för vårdvetenskap

    Författare :Jing Chen; Peiwen Qiu; [2023]
    Nyckelord :;

    Sammanfattning : Background: Stroke is a global health problem, which affects more than 15 millionpeople each year worldwide and leads to high mortality and disability rates. Theprevalence and incidence of stroke in an aging population continued to rise, and somescholars estimated that by 2030, the incidence of stroke was expected to increase toabout three times the current incidence.
