1. Sustainable use of calcium nitrate fertilizer under variable precipitation, soil properties and crop management
Master-uppsats, SLU/Dept. of Soil and EnvironmentSammanfattning : Application of nitrogen fertilizers in agriculture contributes substantially to global greenhouse gas emissions and nitrogen leaching. Accordingly, there is a need to increase knowledge about sustainable farming practices to reduce nitrogen losses to the environment without curtailing crop harvest. LÄS MER
2. Membrane-less porous walls electrolyzer for electrochemical ammonia synthesis
Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)Sammanfattning : n a world of unsustainable growth and increasingly catastrophic climate events, the quest for sustainability is open. Electrochemical ammonia synthesis (EAS) represents an eco-friendly means for green ammonia production. LÄS MER
3. Modelling the full-scale N2O emissions from wastewater treatment plants for identifying mitigation strategies
Master-uppsats, Lunds universitet/Kemiteknik (CI)Sammanfattning : Nitrous oxide (N2O) emissions, which primarily originate from the biological nitrogen removal process, dominate the release of greenhouse gases (GHGs) in wastewater treatment plants (WWTPs). N2O production occurs through dynamic microbial pathways that have a significant impact on the environment compared with other GHG emissions. LÄS MER
4. The Use of Gels for the Removal of Cellulose Nitrate Lacquer on Silver
Kandidat-uppsats, Göteborgs universitet/Institutionen för kulturvårdSammanfattning : The conservation of silver objects mainly constitutes addressing the issues of tarnish removal and of preventing tarnish. For decades lacquer has been used to coat silver objects in order to protect them from tarnishing. LÄS MER
5. Explicit consideration of microbes in quantification of gross N rates based on N-tracing model
Master-uppsats, Göteborgs universitet/Institutionen för geovetenskaperSammanfattning : When studying the nitrogen cycle in soils, the principle of 15N isotope dilution and enrichment is commonly used to measure gross N transformation rates. The measuring data of both organic and inorganic nitrogen substrates are therefore be analysed by Ntrace model. LÄS MER
