  1. 1. Machine learning for molecular property prediction and drug safety

    Master-uppsats, Göteborgs universitet/Institutionen för data- och informationsteknik

    Författare :Kinga Jenei; [2023-10-23]
    Nyckelord :Molecular property prediction; Acid dissociation constant; pKa; Machine learning; Graph Neural Networks; Molecular descriptors; Drug Discovery;

    Sammanfattning : Utilizing machine learning methods for the prediction of acid dissociation (pKa ) values of compounds holds great significance, as pKa is an important parameter, optimized frequently in drug discovery. Accurate prediction of pKa values could potentially provide valuable insights on other molecular properties and thereby support compound design. LÄS MER

  3. 2. A PILOT STUDY ON STAIN REDUCTION Effects of Stains, Cleaning Agents, and Cleaning Methods on Polyester Textiles

    Master-uppsats, Göteborgs universitet/Institutionen för kulturvård

    Författare :Karin Hindborg; [2023-08-28]
    Nyckelord :colour measurements; spot cleaning; suction table; tensile testing; textile con-servation;

    Sammanfattning : The thesis was an experimental pilot study that investigated efficiency and effects of stains and cleaning agents on polyester textiles. A literature review and interviews with textile conservators were used to understand the degradation of polyester fibres and to find suit-able staining and cleaning agents to use in the experiments of the study.

  4. 3. Exploring the interactive effects of light intensity and pH on coral oxygen production

    Master-uppsats, Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Författare :Sara Wirdemark; [2023-08-07]
    Nyckelord :Ocean acidification; light intensity; photosynthesis;

    Sammanfattning : The study aimed to explore the possible interaction between acidification and light intensity and the effects on corals' oxygen production. Interactions between temperature and pH have been thoroughly researched and proven to cause immense stress on the world’s reefs. LÄS MER

  5. 4. Restaurering av grässandhedar genom aktiv markstörning - en jämförelse av florans kolonisation av plöjningar och sandblottor på Revingefältet utanför Lund

    Master-uppsats, Lunds universitet/Examensarbeten i biologi

    Författare :Erik Borgström; [2023]
    Nyckelord :Biology and Life Sciences;

    Sammanfattning : The conservation value of sandy habitats for a flora and fauna adapted to open, light, dry, warm, and often nutrient-poor conditions, is well recognized. Today this environment is threatened by lack of disturbance, fragmentation and exploitation, acidification and increased levels of nitrogen and phosphorus. LÄS MER

  7. 5. Effects of mixed surfactant system on chemical and physical stability of human growth hormone

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

    Författare :Karnsinee Viriyayudhakorn; [2023]
    Nyckelord :human growth hormone; surfactant; refolding; protein stability; physical degradation; chemical degradation; pharmaceutical technology; Technology and Engineering;

    Sammanfattning : In protein formulation, addition of surfactants is commonly executed to enhance product stability and shelf-life. The reason is that surfactants can protect proteins against surface-induced aggregation. However, the interaction between surfactant and protein depends on the type of surfactant used. LÄS MER
