  1. 1. Massbalans av salt, kväve och fosfor i Dynestadsjön : En pilotstudie innefattande flödesmätningar och modellering

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Isak Spett; [2021]
    Nyckelord :Brackish water; fish death; eutrophication; environmental impact; the Baltic Sea; agriculture; SonTek-IQ Plus; MATLAB; Simulink; Bräckt vatten; fiskdöd; övergödning; miljöpåverkan; Östersjön; lantbruk; SonTek-IQ Plus; MATLAB; Simulink;

    Sammanfattning : Dynestadsjön in Gamleby, Västervik municipality, has a history of collapses due to lack ofoxygen and high levels of salt, nitrogen and phosphorus. The high levels of nutrients havegiven rise to deteriorating living conditions for aquatic organisms. LÄS MER

  3. 2. ADDITIVE MANUFACTURING FOR ASSISTIVE TECHNOLOGY : Innovative Design for an Ankle Foot Orthosis

    Master-uppsats, Jönköping University/JTH, Industridesign

    Författare :Theresa Hoai-Thuong Nguyen; [2021]
    Nyckelord :Ankle Foot Orthosis; Orthotics; Assistive Technology; 3D Printing; 3D Scanning; Additive Manufacturing; Self-Expression; Personalization; Customization; Human Rights;

    Sammanfattning : The following report presents a Master thesis project about a re-design of an ankle foot orthosis using additive manufacturing as the production method, conducted by a student in Spring 2020 as part of the Master’s programme Industrial Design at Jönköping University’s School of Engineering. Ankle foot orthoses are the most prescribed lower extremity orthoses worldwide and are worn in a visually obtrusive way making patients feel stigmatized for their disability. LÄS MER

  4. 3. Swedish Nitrogen Flows : A national budget of anthropogenically induced reactive nitrogen

    Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :Vincent Lernbecher; [2021]
    Nyckelord :;

    Sammanfattning : Nitrogen is a fundamental element in all forms of life and a crucial component of our agricultural productivity and global food security. However, excess nitrogen caused by human activity poses a serious threat to the environment and human health. LÄS MER

  5. 4. Brandfarliga vätskor i syrereducerade miljöer

    Kandidat-uppsats, Lunds universitet/Avdelningen för Brandteknik

    Författare :Carl Nilsson; Max Hersner; [2021]
    Nyckelord :Hypoxic air; Brandfarliga vätskor; Reduced oxygen; Limiting oxygen; Cone calorimeter; Flammable liquids; ORS; LOC; CACC; Heat release rate; Mass loss rate; Technology and Engineering;

    Sammanfattning : Unmanned warehouses are increasing in number as workers are replaced by automated robotic systems. This type of facility, among others, is well suited for an oxygen reduction system for fire protection. By lowering the oxygen concentration, the risk of fire propagation is reduced and might be hindered altogether. LÄS MER

  7. 5. Traits of peat- and upland-derived stream dissolved organic carbon in the permafrost region around Abisko, northern Sweden

    Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Nora Kainz; [2021]
    Nyckelord :physical geography; ecosystem analysis; permafrost degradation; DOC; DOC concentration; stable isotope carbon signature; DOC quality; DOC degradation; Atmospheric Sciences and Biogeochemical Cycles; Earth and Environmental Sciences;

    Sammanfattning : Climate change-induced thawing of permafrost mobilizes previously frozen carbon of high potential reactivity, thereby, fuelling microbiological production of greenhouse gases. For this work, an analysis of the quantity, quality, and bioreactivity of DOC in streams from the Stordalen discontinuous permafrost catchment was carried out with stream water samples during the relatively warm summer of 2018.
