  1. 1. Controls over stream temperature in a northern boreal landscape

    Master-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Författare :Oskar Damström; [2023]
    Nyckelord :Aquatic ecosystems; Climate change; Stream warming; Boreal streams;

    Sammanfattning : With widespread increases in air temperature, it is expected that the temperature of aquatic ecosystems will also increase, especially at high latitudes. Warmer streams and rivers could have severe, direct impacts on cold-adapted aquatic fauna but may also indirectly influence species by reducing the amount of suitable habitat. LÄS MER

  3. 2. Mercury in a Swedish landscape over 30 years : a thesis on mercury concentrations in different water-cathments in Krycklan and Degerö stormyr

    Kandidat-uppsats, SLU/Dept. of Forest Ecology and Management

    Författare :Ted Pettersson; Isak Haglund; [2023]
    Nyckelord :Atmospheric deposition; concentrations; dissolved organic carbon; mercury; methylmercury; peatlands; water-catchments;

    Sammanfattning : The purpose of this thesis is to examine trends in concentrations of total mercury (TotHg) and methylmer¬cury (MeHg) in water streams around Vindeln, Sweden, located northwest of Umeå. The relation¬ship between dissolved organic carbon (DOC) and TotHg were also examined in this thesis. LÄS MER

  4. 3. Spatio-temporal drought characteristics in the Limpopo basin from 1918 to 2018 - A case study based on analysis of the Standardized Precipitation Evaporation Index (SPEI)

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

    Författare :Sandra Domingos Sambo; [2021]
    Nyckelord :rdought; Standardized Precipitation Evapotranspiration Index; Limpopo River basin; Normalized difference vegetation index; Mann-Kendall Test; Correlation analysis; Earth and Environmental Sciences;

    Sammanfattning : The identification of the characteristics of drought are of great importance in water resources planning and management. This study explored the characteristics of drought at Limpopo River Basin (LRB) from 1918 to 2018. LÄS MER

  5. 4. Text Mining Methods for Biomedical Data Analysis

    Magister-uppsats, Linköpings universitet/Statistik och maskininlärning

    Författare :Rakhshanda Jabeen; [2021]
    Nyckelord :;

    Sammanfattning : Biological data topic modeling has become a very prevalent topic among researchers in recent times. However, analysing countless research papers and gathering consensus regarding biomedicine is a near-impossible task for any researcher due to the complexity and quantity of material that is published.
