  1. 21. Hur påverkar företableringssubstrat rot- och skottillväxt? : en jämförande studie av företablering av träd i torv, pimpsten och pimpsten med biokol

    University essay from SLU/Dept. of Landscape Architecture, Planning and Management (from 130101)

    Author : Hedda Svendsen; [2021]
    Keywords : träd; företablering; bjälklag; finrötter; substrat; biokol; pimpsten; torv; skott; tillväxt; rotlängd; rotvolym; Prunus cerasifera;

    Abstract : Den här studien undersöker hur företableringssubstrat påverkar rot- och skottillväxt hos träd av arten Prunus cerasifera. Studiens syfte är att undersöka om företablering i substrat av torv, pimpsten och pimpsten med biokol under ett år påverkar tillväxten hos finrötter och årsskott olika för behandlingarna. READ MORE

  3. 22. Modeling groundwater flow using COMSOL to understand the water cycle dynamics and climate change impacts for future groundwater availability in the Matlab region, Southeastern Bangladesh

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Oscar Vandromme; [2021]
    Keywords : Aquifer-Arsenic contamination-Climate change-Groundwater elevation-Model-Sustainability;

    Abstract : Arsenic contamination has been a growing concern for many countries, especially Bangladesh. In Bangladesh, one of the most arsenic-contaminated regions is Chandpur. In this study, groundwater data were analyzed in order to create models to improve knowledge on groundwater flow dynamic in a specific area of Chandpur called Matlab. READ MORE

  4. 23. Phosphorus accumulation in constructed wetlands : A study of 10 wetlands constructed on agricultural clay soils in Södermanland

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Gabriella Corbee; [2021]
    Keywords : Phosphorus retention; sedimentation; hydraulic load; Fosforavskiljning; sedimentation; hydraulisk belastning;

    Abstract : Eutrophication is a major problem causing algal blooms and impaired water quality, especially regarding coastal areas and seas. It is a result of an excessive supply of nutrients such as phosphorus (P), where agriculture accounts for the largest share of the anthropogenic nutrient load. READ MORE

  5. 24. Tuning the composition of metallic nanoparticles for catalytic applications

    University essay from KTH/Kemi

    Author : Anthony Ropp; [2021]
    Keywords : catalysis; nanoparticles; frustrated Lewis pairs; synthesis; core-shell;

    Abstract : Industries’ interest in nanomaterials is tremendous and catalysis is one of their applications. Catalysts allow reactions to occur under milder conditions, avoiding committing excessive heat or pressure to foster reactions. READ MORE

  6. 25. Long-term deformation of balanced cantilever bridges due to non-uniform creep and shrinkage

    University essay from KTH/Betongbyggnad

    Author : Sidra Akbar; Mathias Carlie; [2021]
    Keywords : Balanced cantilever bridges; box girder cross-section; concrete; non-uniform creep and shrinkage; Bažant’s B4 model; Eurocode 2; long-term deformations; finite element analysis; Freivorbau broar; lådtvärsnitt; betong; ojämnkrypningoch krympning; BažantsB4 modell; Eurokod 2; långtidsdeformationer; finita element analys;

    Abstract : Balanced cantilever bridges have historically experienced excessive deformations. Previous researchsuggeststhat the cause may be due to differential thickness in the box girder cross-section and underestimation of creep and shrinkage. READ MORE
