16. Response of foraminifera Ammonia confertitesta (T6) to ocean acidification, warming, and deoxygenation - An experimental approach
University essay from Lunds universitet/Geologiska institutionenAbstract : Ocean acidification, warmer temperatures, and the expansion of hypoxic zones in coastal areas are direct consequences of the increase in anthropogenic activities. However, so far, the combined effects of these stressors on calcium carbonate-secreting marine microorganisms - foraminifera are complex and poorly understood. READ MORE

17. Characterization of a novel bacteriumoriginating from a biogas process
University essay from SLU/Department of Molecular SciencesAbstract : An anaerobic bacterium, isolated from an enrichment culture originating from a biogas reactor operating at high ammonia conditions, was characterised via various tests. An analysis of the 16S rRNA gene confirmed that the closest relative was Desulfotomaculum halophilum with 92,5 % similarity. READ MORE

18. Model Predictive Urea Dosing Control Strategy for Heavy-Duty Diesel Vehicles
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : Stricter requirements on the reduction of Nitrogen Oxides (NOx) in the emissions of heavy-duty diesel vehicles drives development for more efficient aftertreatment systems. An ammonia covered catalyst is one of the most successful technologies in reducing NOx by converting it into the harmless byproducts water and nitrogen. READ MORE

19. Isolation of an ammonia-tolerant syntrophic butyrate-oxidizing bacterium originating from a thermophilic biogas digester
University essay from Uppsala universitet/Institutionen för biologisk grundutbildningAbstract : Syntrophic relationships between fatty acid degrading bacteria and hydrogenotrophic methanogens are important for a well-functioning anaerobic degradation process during biogas production from organic waste material. This is particularly important in biogas processes fed protein-rich material as their degradation gives rise to high levels of ammonia, which inhibits many microorganisms. READ MORE

20. Renewables and electrification in Europe, A critical analysis
University essay from Lunds universitet/Miljö- och energisystemAbstract : Electrification of processes has become the cornerstone of the strategy to decarbonise energy supply, especially in recent years. This study aims to define the main issues underlying the electrification of the European energy mix, especially those caused by an increasing share of intermittent energies. READ MORE
