  1. 1. Emissions of nitrous oxide associated with frost killed cover crops

    University essay from SLU/Dept. of Biosystems and Technology (from 130101)

    Author : Felicia Olofsson; [2022]
    Keywords : Nitrous oxide; cover crops; greenhouse gases; freeze-thaw cycles;

    Abstract : Agriculture is responsible for approximately 80% of anthropogenic emissions of the potent and long-lived greenhouse gas nitrous oxide (N2O). N2O emissions from agricultural soils are characterized by high temporal and spatial variability and often peak in short bursts related to events such as precipitation, fertilization and soil thawing.

  3. 2. GAC filter Design Criteria for Wastewater Treatment for Removal of Organic Micropollutants – A Literature Review

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Bhargav Reddy Elavarthi; [2021]
    Keywords : micropollutants; activated carbon filtration; empty bed contact time EBCT ; pharmaceuticals; breakthrough curves; adsorption; PFOS; carbon use; water and environmental engineering; Technology and Engineering;

    Abstract : Granular Activated Carbon (GAC) is nowadays suggested as a fourth (quaternary) treatment step at municipal wastewater treatment plants to remove certain chemicals and particularly organic micropollutants (OMPs). This work investigated the different factors that affect the performance of the GAC filter for the removal of micropollutants in a municipal wastewater treatment plant. READ MORE

  4. 3. Testing the potential to evaluate vegetation optical depth with ecosystem water dynamics in a temperate forest

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Ainahu Abdul Hamid; [2021]
    Keywords : Physical geography; Ecosystem analysis; Vegetation optical depth; Temperate Forest; Climate; LPJ-GUESS; Evapotranspiration; Leaf water potential; Isohydricity; Hydraulic failure; Carbon starvation; Earth and Environmental Sciences;

    Abstract : Warming trends have been associated with drought which induces and heightens agents and factors that cause tree mortality. Remotely sensed observations are increasingly being used in vegetation studies and are obtained from Earth observation satellites. READ MORE

  5. 4. Factors determining agricultural damage from foraging ungulates : an experimental study using exclosures in oat- and grass fields

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

    Author : Markus Velin; [2021]
    Keywords : ungulates; foraging; biomass loss; NDVI; drones;

    Abstract : Ungulates foraging on and damaging agricultural crops are a common phenomenon worldwide, which create conflicts between stakeholders with different economic interests. Further, the spatiotemporal distribution of food and the quality of food is often referred to as the “foodscape”. READ MORE

  6. 5. Iron-catalyzed graphitization of biochar to produce graphitic carbon materials

    University essay from KTH/Materialvetenskap

    Author : Ziyi Shi; [2021]
    Keywords : graphite; biochar; catalyst; catalytic graphitization; grafit; biokol; katalysator; katalytisk grafitisering;

    Abstract : Demand for high-quality graphite is expected to experience an extraordinary growth rate, in large part due to its wide range of industrial applications such as adsorbents, lubricants, electrodes, etc. This thesis developed a novel sustainable approach to produce green-graphite materials by applying biochar, acarbon-rich valuable by-product obtained from biomass, as a carbon precursor.
