  1. 1. Characterisation of Non-metallic Inclusions in Special Steels using Electrolytic Extraction

    Master-uppsats, KTH/Materialvetenskap

    Författare :Josefin Mvele Svensson; [2024]
    Nyckelord :Non-metallic inclusions; electrolytic extraction; SEM; Icke-metalliska inneslutningar; elektrolytisk extraktion; SEM;

    Sammanfattning : When producing high strength special steels strict requirements are in place to assure the quality of the final product, both in terms of harmful elements and  the  content  of  non-metallic  inclusions  (NMI).  Achieving  cleanliness  is a  gradual  process  where all  the  steps  of  the  production  process  are  inter- connected, meaning that it is crucial to know the influence of each step in order to assure the contents of the final product.

  3. 2. Impact of nitrogen availability and nitrogen structural composition on fungal enzymatic activity and growth : how nutrient availability governs response and development of three saprotrophic Basidiomycetes

    Master-uppsats, SLU/Dept. of Soil and Environment

    Författare :Bella Strid; [2024]
    Nyckelord :nitrogen; tannins; condensed tannins; MnP; manganese peroxidase; peptidase; saprotrophic basidiomycetes;

    Sammanfattning : Fungi excrete a wide variety of extracellular enzymes to scavenge for nutrients, such as the often scarce yet essential nutrient nitrogen. All fungi produce highly specialized hydrolytic enzymes, e.g. peptidases, that depolymerize organic molecules. LÄS MER

  4. 3. Hur kan lärarrollen förstås och anpassas i relation till samskapande undervisning? : Genom studenternas perspektiv Utvecklingsarbete

    L3-uppsats, Luleå tekniska universitet/Institutionen för hälsa, lärande och teknik

    Författare :Hanna Rached Rydberg; [2024]
    Nyckelord :co-creative teaching; group work; reflect nuancedly; motivation;

    Sammanfattning : When I found out that in 2022 there were about 18 000 students who did not have the qualifications to applay to high school after they finished ninth grade, I became curious about how I, in my future profession as a teacher, will be able to help students achieve passing grades in my subject social studies at the end of ninth grade. I have therefore studied what is required of the school´s curriculum Lgr 22 and how I can motivate the students as well as which working methods are presented in theory and previous research as the best working methods to enable the students to reach the right understanding of different subjects.

  5. 4. Do viscous flows slip?

    Master-uppsats, Göteborgs universitet/Institutionen för matematiska vetenskaper

    Författare :Björn Sjösvärd; [2023-12-21]
    Nyckelord :Mathematics; partial differential equations; multivectors; Hodge de-compositions; the Stokes equation; Hodge boun;

    Sammanfattning : In this thesis, the Stokes equation is discussed and solved under different boundary conditions. The Stokes equation governs the flow of viscous liquids, for example honey or syrup. The first chapters in the thesis provides an introduction to multivector algebra and analysis, with the aim of presenting the concept of Hodge decompositions. LÄS MER

  7. 5. TROFISK ÖVERFÖRING OCH TOXISKA EFFEKTER AV (NANO-)PARTIKLAR FRÅN ELEKTRONISKT AVFALL

    Kandidat-uppsats, Göteborgs universitet / Institutionen för biologi och miljövetenskap; Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Författare :Elvira Hagman; [2023-06-22]
    Nyckelord :;

    Sammanfattning : Today, nanoparticles (NPs) are being included in an increasing number of products, and with that comes the dispersion of NPs in the environment. However, the ecological impact of NPs remains largely unexplored, particularly in regards to real emissions with complex compositions of NPs and other pollutants. LÄS MER
