1. Controls of the partitioning of nitrate between DNRA and denitrifiers
Master-uppsats, SLU/Dept. of Forest Mycology and Plant PathologySammanfattning : In arable soils, the importance of denitrification, a respiratory process where nitrate (NO3-) is stepwisely reduced to nitrogen gas and nitrous oxide (N2O) is well established. More recently has dissimilatory nitrate reduction to ammonium (DNRA) gained interest as its importance in agricultural soils might have been largely overlooked. LÄS MER
2. Spatial and temporal changes in microbial community composition in a full-scale woodchip bioreactor for treating mine water
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för biologisk grundutbildningSammanfattning : Incomplete detonation of nitrogen-based explosives can lead to abundant levels of nitrate in mine groundwater. The possibility of reducing nitrogen levels from the wastewater through denitrification, anammox and DNRA has been investigated using a full-scale bioreactor. The bioreactor is situated subsurface and is filled with pine woodchips. LÄS MER
3. Effect of distance measures and feature representations on distance-based accessibility measures
Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapSammanfattning : Distance-based accessibility measures are often built using vector representations of origin and destination features, and Euclidean or network-based distances. There are few comparisons of how the choice of feature representations and distance types affects results. Existing comparisons often use Spearman’s rank correlation coefficients. LÄS MER
