  1. 1. Cancerresistens hos den afrikanska nakenråttan (Heterocephalus glaber)

    Kandidat-uppsats, SLU/Dept. of Biomedical Sciences and Veterinary Public Health

    Författare :Maja Öhlin; [2018]
    Nyckelord :nakenråtta; Heterocephalus glaber; fysiologi; cancer; tumör; neoplasi; cancerresistens;

    Sammanfattning : Nakenråttan (Heterocephalus glaber) är ett däggdjur som lever hela sitt liv under jord i eusociala kolonier i östra Afrika. Den är jordens mest långlivade gnagare med en maximal livslängd på över 30 år, vilket är häpnadsväckande i jämförelse med 4 år hos en mus i samma storlek. LÄS MER

  2. 2. Nitrogen removal from municipal wastewater by mainstream Partial Nitritation/Anammox process

    Master-uppsats, KTH/Vatten- och miljöteknik

    Författare :Alessio Robiglio; [2018]
    Nyckelord :Mainstream; Deammonification; IFAS; UASB; Anammox; Anoxia; Aeration; Online; Monitoring; Inhibition; Wastewater;

    Sammanfattning : 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.

  3. 3. Long-term trends in bottom water chemistry of Swedish lakes

    Magister-uppsats, SLU/Dept. of Aquatic Sciences and Assessment

    Författare :Jelena Rakovic; [2017]
    Nyckelord :hypolimnion; sediment; oxygen; dissolved organic carbon; phosphorus; ammonium; silica;

    Sammanfattning : 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

  4. 4. 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 geovetenskaper

    Författare :Ida Eriksson; [2017]
    Nyckelord :climate change; lake modeling; MyLake; temperature; oxygen; boreal lakes; DOC; water quality; anoxia; Klimatförändringar; modellering; MyLake; temperatur; syre; DOC; vattenkvalitet; syrebrist;

    Sammanfattning : 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

  5. 5. 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 geovetenskap

    Författare :Guillermo Guindal Estévez; [2015]
    Nyckelord :hydropower; riparian; erosion; Sweden; seed; flow alteration.;

    Sammanfattning : 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
