1. 1. SOIL GROSS NITROGEN MINERALISATION AND FOREST GROWTH IN FOUR HEMIBOREAL FOREST STANDS IN SOUTHWEST SWEDEN

   University essay from Göteborgs universitet / Institutionen för biologi och miljövetenskap

   Author : Linnéa Eriksson; [2023-04-20]
   Keywords : soil C:N; forest production; 15N isotope dilution; gross N mineralisation; ammonium; soil carbon; soil nitrogen; root exudates; stoichiometric decomposition; boreal forests; priming; microbial C limitation;

   Abstract : Boreal and temperate forests together make up the largest terrestrial net C sink in the world. They take up carbon dioxide (CO2) from the atmosphere and store it in plant biomass and soil as they grow, making them crucial in mitigating global climate change. READ MORE

3. 2. Modelling Micropollutant Removal Through Ozonation in Wastewater

   University essay from Lunds universitet/Kemiteknik (CI)

   Author : Maximiliano Andrés Oportus Foster; [2023]
   Keywords : Micropollutants; water reuse; wastewater treatment models; ozonation; computer modeling; water and environmental engineering; Technology and Engineering;

   Abstract : Proper management of water resources is a key to climate change adaptation and resilience in modern societies. Adequate treatment of wastewater is essential for ensuring the sustainability of the water cycle and the health of the environment and the ecosystems that inhabit it. READ MORE

4. 3. Sustainable use of calcium nitrate fertilizer under variable precipitation, soil properties and crop management

   University essay from SLU/Dept. of Soil and Environment

   Author : Liliana Marcela Daza Gomez; [2023]
   Keywords : nitrogen.; calcium nitrate; ammonium-based fertilizers; urea; nitrate leaching; nitrous oxide emissions; crop yield;

   Abstract : 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. READ MORE

5. 4. Influence of pulsing on PVD TiAlN coating microstructure and mechanical properties : Master thesis project on the impact of deposition parameters on performance and properties of PVD titanium aluminum nitride.

   University essay from Karlstads universitet

   Author : Marcus Roseen; [2023]
   Keywords : ;

   Abstract : This thesis investigates the influence of pulsing on the mechanical properties of PVD TiAlN coatings. The thesis focuses on defects caused by droplets during the arc-evaporation technique by altering the duty time, which affects mechanical properties. READ MORE

6. 5. Effekten av gödsling med arGrow® granulat på barrplantors tillväxt efter de första två växtsäsongerna

   University essay from SLU/School for Forest Management

   Author : Karl-Anders Wickberg; Mattias Eliasson; [2023]
   Keywords : arginin; plantgödsling; aminosyror;

   Abstract : Tillgången på näringsämnen i marken är mycket stort i förhållande till växternas behov, men ändå är näringstillförseln ofta en tillväxtbegränsande faktor för växterna. De näringsämnen som behövs i störst mängd är kväve, som ofta är hårt bundet i svårlösliga kemiska föreningar. READ MORE
