  1. 1. Greenhoue gas flux over a 50-year post permafrost thaw gradient. Decomposition of soil organic carbon from the Swedish tussock tundra.

    University essay from Göteborgs universitet/Institutionen för geovetenskaper

    Author : Johan Martinelli; [2020-02-11]
    Keywords : greenhouse gas; permafrost;

    Abstract : As the globe is warming the extent of permafrost drastically decreases in the high latitudes. Upon thawthe stored soil organic carbon (SOC) undergoes rapid decomposition and is partly released as trace gasesto the atmosphere. READ MORE

  2. 2. Hydrological catchment analysis from characterisation of organic matter in stream water

    University essay from Göteborgs universitet/Institutionen för geovetenskaper

    Author : Hannes Berg Wiklund; [2020-02-05]
    Keywords : Organic matter; Time-of-flight mass spectrometry; aquatic chemistry; catchment hydrology;

    Abstract : Organic matter (OM) in aquatic systems is a complex field which have rapidly developed duringthe last decade due to the introduction of high resolution mass spectrometers. The compositionof OM in the aquatic environment is directly dependent on factors such as oxygen supply, pHand the flow rate in the local system. READ MORE

    Keywords : nutrient recovery; manure management; ecological sanitation; material flow analysis; East African agriculture;

    Abstract : The global agriculture of today is to a high degree dependent on mineral fertilisers that through a constant accumulation of nitrogen (N) and phosphorus (P) in the biosphere contribute to greenhouse gas emissions and eutrophication of water bodies. At the same time, agricultural productivity around the world is largely constrained by low inputs of plant nutrients. READ MORE

  5. 5. Considerations for the Establishment of an Anaerobic Biofilm in an AnMBBR

    University essay from Lunds universitet/Teknisk mikrobiologi

    Author : Emma Månsson; [2020]
    Keywords : Anaerobic; MBBR; biofilm; carrier; methane; applied microbiology; teknisk mikrobiologi; Technology and Engineering;

    Abstract : Behandling av avloppsvatten för att avlägsna ämnen som kan ha en negativ påverkan på den mänskliga hälsan och naturen är mycket viktigt innan vattnet återanvänds eller släpps ut i naturen. Intresset för anaerob vattenrening har ökat eftersom det är ett bra komplement till aeroba processer, samt för att det producerar energi i form av metangas. READ MORE
