1. 1. Yearly distribution and composition of per- and polyfluoroalkyl substances (PFAS) in Luleå wastewater treatment plant

   University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

   Author : Moa Sjöberg; [2023]
   Keywords : PFAS; WWTP; Wastewater treatment; Consumer products; Precursors;

   Abstract : PFAS (per- and polyfluoroalkyl substances) are a large group of substances that are used in a large variety of products because of their unique water and dirt repellent properties. The substances are extremely persistent and can spread over large distances in groundwater, surface water, and in the air, which makes them an environmental and a health concern. READ MORE

3. 2. Controls over stream temperature in a northern boreal landscape

   University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

   Author : Oskar Damström; [2023]
   Keywords : Aquatic ecosystems; Climate change; Stream warming; Boreal streams;

   Abstract : 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. READ MORE

4. 3. Dynamic Warning Signals and Time Lag Analysis for Seepage Prediction in Hydropower Dams : A Case Study of a Swedish Hydropower Plant

   University essay from Uppsala universitet/Datalogi

   Author : Lovisa Olsson; Julia Hellström; [2023]
   Keywords : hydropower; dam safety; dam monitoring; seepage; prediction models; data-driven methods; artificial intelligence; AI;  linear regression; Support Vector Regression; SVR; Long Short-Term Memory; LSTM;

   Abstract : Hydropower is an important energy source since it is fossil-free, renewable, and controllable. Characteristics that become especially important as the reliance on intermittent energy sources increases. However, the dams for the hydropower plants are also associated with large risks as a dam failure could have fatal consequences. READ MORE

5. 4. FLOWERING TIME DEPENDENCE ON MICROCLIMATE ACROSS AN ELEVATIONAL GRADIENT IN ARCTIC PLANT COMMUNITIES

   University essay from Göteborgs universitet / Instiutionen för biologi och miljövetenskap

   Author : Maria Pavolotskaia; [2022-07-06]
   Keywords : The Arctic; flowering time; flowering phenology; elevation; elevational gradient; temperature; snowmelt; snow cover; microclimate.;

   Abstract : The Arctic is the fastest-warming region on Earth. Arctic plant communities are highly sensitive to temperature change; temperature-dependent advancement of flowering dates has already been observed in the Arctic. Flowering time is critical for reproductive success. READ MORE

6. 5. Snow cover related camouflage mismatch decreases survival

   University essay from SLU/Dept. of Wildlife, Fish and Environmental Studies

   Author : Pieter Otte; [2022]
   Keywords : climate change; snow cover; seasonal colour coat; crypsis; mismatch; camera trap; survival analysis;

   Abstract : Climate change is expected to decrease winter severity at high latitudes, resulting in reduced days of snow cover. Several mammalian and avian species in the northern hemisphere express a seasonal colour coat (SCC) making them white in winter periods and brown or dark in summer. READ MORE
