6. Nitrogen removal from municipal wastewater by mainstream Partial Nitritation/Anammox process
Master-uppsats, KTH/Vatten- och miljöteknikSammanfattning : Mainstream Partial Nitritation/Anammox, also known as Mainstream Deammonification, is a promising technology for future wastewater purification that aims to remove nitrogen from wastewater in order to prevent the eutrophication. It is less costly than the traditional nitrification/denitrification process and it heads towards the direction of converting the WWTPs from energy consuming into energy producing facilities. LÄS MER
7. Long-term trends in bottom water chemistry of Swedish lakes
Magister-uppsats, SLU/Dept. of Aquatic Sciences and AssessmentSammanfattning : Long-term monitoring of lake water is essential for tracking local and long-range effects of anthro-pogenic pressure and to inform policy aiming at mitigating human environmental impacts. Swedish reference lakes are recovering from acidification; are subject to climate change and increasing inputs of terrestrial dissolved organic matter (DOM). LÄS MER
8. Nox2/4 inhibition in NB69 during ischemia/reperfusion : Inhibition of ROS-production using M4, M107, and M114
Kandidat-uppsats, Högskolan i Skövde/Institutionen för hälsa och lärandeSammanfattning : Cerebral stroke has become one of the leading causes of death and disability worldwide. During an ischemic stroke, oxygen and nutrient deprivation occurs, which combined lead to cell starvation, anoxia, and eventually cell death. LÄS MER
9. A modeling study of the impact of climate change on temperature and oxygen profiles in three Swedish lakes
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för geovetenskaperSammanfattning : Climate change is one the greatest environmental challenges of our time, both due to direct eectssuch as global warming but also due to the potential of the climate acting as a driver for otherenvironmental problems. This thesis aims to evaluate the impact of climate change on thermal properties and the content and distribution of dissolved oxygen in boreal lakes. LÄS MER
10. Impacts of hydropower dams operations on plants : A greenhouse experiment on the response of germination and performance and survival of plant seedlings to direct and indirect effects of hydrological alterations resulting from hydropower dam operations
Kandidat-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskapSammanfattning : This work helps increasing our general understanding of how plants behave under altered hydrological conditions which occur along rivers regulated by hydropower dams. Usually, natural-real environments are highly unpredictable. Consequently, research based on field data becomes challenging and results may contain uncertainty. LÄS MER
