  1. 1. 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

    University essay from SLU/Dept. of Soil and Environment

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

    Abstract : 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. READ MORE

  3. 2. En kritisk granskning av kalkylverktyget BIMitigation : möjligheter och begränsningar i ett användarperspektiv

    University essay from SLU/Dept. of Urban and Rural Development

    Author : Nils Vestlund; [2023]
    Keywords : BIMitigation; bygg- och anläggningsprocessen; hållbar stadsplanering; LCA; växthusgasutsläpp; materialval; Revit;

    Abstract : Detta arbete undersöker nyttan med BIMitigation, ett verktyg som beräknar och visualiserar utsläppen av växthusgaser från anläggningsprojekt. Växthusgasutsläpp från mänsklig aktivitet orsakar varmare temperaturer vilket i sin tur leder till stigande havsnivåer och extremväder såsom skyfall och värmeböljor (Masson-Delmotte et al. READ MORE

  4. 3. Application of ring statistics to characterise graphitisation of carbon fiber heat shields under atmospheric re-entry conditions

    University essay from KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

    Author : Hamish Keay; [2023]
    Keywords : Aerospace; Heat shields; Re-entry; Graphitisation; Carbon fiber; Carbon phenolic; Ring statistics; Graph theory; Molecular Dynamics; återinträde; grafitisering; kolfiber; kolfenol; ringstatistik; grafteori; molekylär dynamik;

    Abstract : Carbon fibers submitted to high temperatures (>2000 °C) experience a permanent increasein their thermal conductivity. This change has been attributed to a change in the molecularstructure due to graphitisation. READ MORE

  5. 4. Dynamic Performance of a Tall Building to Earthquake Loading : Finding the optimum mass and stiffness

    University essay from KTH/Bro- och stålbyggnad

    Author : Andrés Alonso San Segundo; [2022]
    Keywords : ;

    Abstract : With the increasing cost of land, the development of ultra-high performance concrete, and the technological advancements in equipment and machinery, we are able to construct and refurbish skyscrapers like never before. How they are built, what materials they use, or what structural system defines them, all affect their dynamic response, which in the end is the combination of the stiffness and mass, two key parameters in engineering of tall buildings.

  6. 5. Optimal collection grid and transmission line topology for the grid connection of an offshore multi-source park.

    University essay from Uppsala universitet/Elektricitetslära

    Author : Alfred Nerby; [2022]
    Keywords : Renewable; Wind; Solar; multi-source; park; collection grid; substation; transmission; HVAC; HVDC; converters; shunt reactors; transformer; losses; CAPEX; OPEX;

    Abstract : As spacial restrictions become more and more of an issue for renewable energy parks onshore, more developers are turning offshore to develop future production. The desire for a diversity of energy sources combined with a desire to utilize space efficiently has sparked an interest in renewable energy parks where more than one energy source occupy the space.
