  3. 2. Debugging metabarcoding for insect biodiversity studies

    Författare :Daniel Marquina Hernández; Fredrik Ronquist; Owen Wangensteen; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; metabarcoding; insects; non-destructive; DNA extraction; Malaise trap; preservative ethanol; environmental DNA; systematisk zoologi; Systematic Zoology;

    Sammanfattning : Insects are one of the most abundant and diverse animal groups, and they include many valuable ecological indicator species, but taxonomic discovery projects and biodiversity surveys targeting this group are often challenging. While mass trapping devices allow the collection of insects in great numbers, the task of identifying the species present is a painstaking and resource-demanding process. LÄS MER

  4. 3. Combination of heating and preservative impregnation of wood for outdoor exposure

    Författare :Ekaterina Sidorova; Magdalena Kutnik; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wood Physics; Träfysik;

    Sammanfattning : The research is presented as a composite thesis containing a theoretical explanatory review based on four scientific articles. The thesis covers the investigation of wood modification methods, which in the future could possibly be developed further to enhance the performance of wood products in an efficient and economical way.

  5. 4. Protein-Surfactant Interactions in Complex Systems : Study of Physical Stability of Proteins and Peptides

    Författare :Johanna Hjalte; Avdelningen för livsmedel och läkemedel; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; therapeutic proteins; NMR nuclear magnetic resonance ; physical stability; surfactant protein interaction; preservative protein interaction; peptide aggregation;

    Sammanfattning : My objective has been to characterize protein-surfactant interactions in pharmaceutically relevant formulations. Thus, the behavior of selected excipients, proteins and peptides has been studied as the system in question is driven to the verge of instability in different manners; by inducing aggregation, by inducing surfactant complexation, or by inducing precipitation by increasing ionic strength in the presence of preservative.

  7. 5. Industrially Pre-Treated Potatoes (Solanum tuberosum L.) Served in Large-Scale Food Service Systems

    Författare :Klara Sjölin; Avdelningen för livsmedel och läkemedel; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Potatoes Solanum tuberosum L. ; large-scale food service system; Industrial pre-treatment; subsurface hardening; Potatoes Solanum tuberosum L. ; subsurface hardening; industrial pre-treatment; large-scale food service systems;

    Sammanfattning : In Swedish schools, a warm lunch is served every day. The lunch is prepared in a largescale food service system and includes steam-cooked potatoes several times per week. The potatoes are often industrially pre-treated to facilitate the handling and logistics required to cook hundreds of meals in a couple of hours. LÄS MER
