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

    University essay from SLU/Dept. of Forest Ecology and Management

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

    Abstract : 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. READ MORE

  3. 2. 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)

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

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

    Abstract : 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. READ MORE

  4. 3. Text Mining Methods for Biomedical Data Analysis

    University essay from Linköpings universitet/Statistik och maskininlärning

    Author : Rakhshanda Jabeen; [2021]
    Keywords : ;

    Abstract : 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.

  5. 4. Long-term phosphorus trends in Swedish rivers and streams : widespread and persistent nutrient decline

    University essay from SLU/Dept. of Aquatic Sciences and Assessment

    Author : Sara Camiolo; [2021]
    Keywords : eutrophication; rivers; streams; phosphorus;

    Abstract : Phosphorus (P) is often considered the limiting nutrient for freshwater productivity because of its relevant role in regulating algal production and determining community composition. The concern for increasing anthropogenic P inputs registered since the last century has shaped environmental policies around the world to limit the effects of algal bloom (also known as eutrophication) in freshwater ecosystems through the establishment of maximum threshold nutrient concentrations.

  6. 5. Remote sensing-based monitoring of snow cover dynamics and its influence on vegetation growth in the Middle Atlas Mountains

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Nezha Acil; [2016]
    Keywords : grasslands; shrublands; forests; Morocco; mountains; monitoring; remote sensing; MODIS; snow; vegetation; Physical Geography; Ecosystem analysis; GIS; Earth and Environmental Sciences;

    Abstract : Endowed with diverse vegetation covers, the Middle Atlas Mountains receive substantial snowfall in winter, which contributes to plant hydration during the growing season. Using remotely-sensed imagery, this study aims to assess the trends in snow cover variations between 2000 and 2015, analyse the local influence of snowpack persistence on vegetation growth and evaluate the significance of this effect by comparing snow-fed and non-snow-fed sites.
