  1. 11. Wall-Resolved and Wall-Modelled LES for a NACA4412 Wing Profile in OpenFOAM

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : Nikolaos Charisoudis; [2024]
    Keywords : ;

    Abstract : The purpose of this study is to perform computational fluid dynamics (CFD) simulationfor an incompressible flow around an airfoil and investigate the aerodynamicproperties for different Reynolds numbers (400, 000 and 1, 000, 000) based on the chordlength, at the moderate angle of attack (AoA) of 5o . For this purpose a detailedevaluation of wall-resolved and wall-modelled large-eddy simulations (LES) wereconducted for the NACA4412 wing profile. READ MORE

  3. 12. Can precommercial thinning be used to create more diversity after planting spruce?

    University essay from SLU/Southern Swedish Forest Research Centre

    Author : Astrid Bygge; [2024]
    Keywords : Forestry; pre-commercial; stand structure; heterogeneity; silviculture; mixed forests; monoculture; Picea abies; Betula spp.;

    Abstract : Mixed forests will harbour other ecosystem services than a planted coniferous monoculture. This study used early results from a long-term experiment to examine if different precommercial thinning treatments can be used to increase diversity in planted stands of Norway spruce (Picea abies) mixed with high densities of natural regeneration of birch (Betula spp. READ MORE

  4. 13. The Potential to Target Smaller Sized Baltic Herring to Decrease the Dietary Exposure - an Assessment Based on Dioxin Samples from the Southern Baltic

    University essay from Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Author : Sofie Gustafsson; [2024]
    Keywords : Dioxin; PCDD Fs; dl-PCBs; Herring; Baltic; Fishery; Technology and Engineering;

    Abstract : PCDD/Fs and dl-PCBs, or more commonly referred to as dioxin and dioxin like substances are compounds present in our surrounding environment. As some congeners of these have been shown to be toxic, they are regulated under the Stockholm Convention. READ MORE

  5. 14. EFFECTS OF COMMERCIAL NANO-LIME PRODUCTS AS A CONSOLIDATION METHOD FOR WALL PAINTINGS An experimental case study

    University essay from Göteborgs universitet/Institutionen för kulturvård

    Author : Hannah Petrini; [2023-11-07]
    Keywords : wall paintings; Dalby Church; nano-lime; consolidation; Nanorestore®; Nanorestore Plus®; conservation of wall paintings;

    Abstract : Some of the main deterioration problems concerning wall paintings is structural degradation of the wall painting and the flaking of the painted layer. Consolidation, both in the form of reinforcement of the rendering of the wall painting and the re-adherence of a flaking paint layer to the underlying substrate, have thus been an important part of conservation efforts concerning wall paintings.

  6. 15. PLASTER CASTS AND CORROSION AN EXPERIMENTAL STUDY ON REMOVAL OF CORROSION PRODUCTS FROM PLASTER CASTS

    University essay from Göteborgs universitet/Institutionen för kulturvård

    Author : Gabriella Zimmerman; [2023-11-07]
    Keywords : plaster cast conservation; iron corrosion staining; xanthan gel; Arbocel®; latex cleaning; chelating agents;

    Abstract : Conservation of plaster casts is complex due to the nature of the material itself. Corrosion of armature and metal structural supports is one of the most common causes of damage in plaster casts and subsequent corrosion staining. READ MORE
