    Author : Vincent Lernbecher; [2021]
    Keywords : ;

    Abstract : 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. READ MORE

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

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Nora Kainz; [2021]
    Keywords : 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;

    Abstract : 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.

    Abstract : Comprehensive rehabilitation projects of dam spillways are made in Sweden, due to stricter dam safety guidelines for their discharge capacity. The Piano Key Weir (PKW) is an innovative design which has proven effective through several renovation projects made in many countries including France. READ MORE

  6. 5. Public transport origin-destination matrices: pattern recognition and short-term prediction

    University essay from KTH/Numerisk analys, NA

    Author : Francesco Ferranti; [2020]
    Keywords : Statistics; machine learning; clustering; regression; OD matrices; Statistics; machine learning; clustering; regression; OD matrices;

    Abstract : Origin-Destination (OD) matrices are an essential tool in transport planning and management to model user travel patterns. An OD matrix is a picture of the public transport passengers demand in a specific temporal window The use of the metropolitan transportation system as an alternative to private cars enables a decrease of CO2 emissions, air pollution and traffic noise.
