1. 1. Biochar from separated digestate and pig manure as soil amendment

   University essay from SLU/Dept. of Soil and Environment

   Author : Lovisa Nissen; [2022]
   Keywords : separation; screw press; incubation study; CO2 emission; N mineralization;

   Abstract : The situation in and around the Baltic Sea, with large areas with hypoxia in the sea and areas in the watershed with a high concentration of animal farms, has led to a need to increase the nutrient recycling of animal manure. High levels of phosphorus (P) in the soil lead to leaching, and by reducing the P-level in organic fertilizers, this leaching can be reduced. READ MORE

3. 2. Evaluation of DC Fault Current in Grid Connected Converters in HVDC Stations

   University essay from Uppsala universitet/Institutionen för elektroteknik

   Author : Soham SinhaRoy; [2022]
   Keywords : Symmetrical monopole; HVDC LCC and VSC; CTL; MMC; Converter reactor; DC smoothing reactor; DC pole-to-pole fault; Peak factor; SCC; SCR; PSCAD EMTDC;

   Abstract : The main circuit equipment in an HVDC station must be rated for continuous operation as well as for stresses during ground faults and other short circuits. The component impedances are thus selected for proper operation during both continuous operation and short circuit events. READ MORE

4. 3. Electrical wiring of Shewanella oneidensis MR-1 with osmium polymers of different redox potentials

   University essay from Lunds universitet/Kemiska institutionen; Lunds universitet/Beräkningskemi

   Author : Laleh Tavakoli; [2021]
   Keywords : Analytical Chemistry; Bio-Analytical Chemistry; Electrochemistry; Bacteria; Osmium redox polymers; Shewanella Oneidensis MR-1; electrode; Microbial electrosynthesis; Electron transfer; Chemistry;

   Abstract : The results of studies have shown that the several applications such as microbial electrochemical system (MES), bio-electrochemical systems (BESs) and production of beneficial chemicals are due to electrochemical connection among electrodes and microorganisms. The following two factors are important in choosing the microbe mediated electrochemical biosensors: I) Binding of bacterial cells on the electrode, II) Efficient electron transfer (EET) between the electrode and the cells by a mediator.

5. 4. Applicering av kväve i fast och flytande form : effekt på växttillgänglighet i åkermark

   University essay from SLU/Dept. of Soil and Environment

   Author : Elizabeth Lövstaf; [2020]
   Keywords : fast gödselmedel; flytande gödselmedel; ammonium; nitrat; ammoniumfixering; regnsimulering;

   Abstract : Kvävegödselmedel är det mest använda gödselmedlet i Sverige till följd av dess goda effekter på en grödas kvalité och avkastning. Tillförsel av kväve (N) görs vanligen i formerna nitrat (NO3-) och ammonium (NH4+), gärna i kombination med andra näringsämnen. READ MORE

6. 5. Influence of fuel mix on mass balance of Cl, S, and K in a long rotary kiln

   University essay from Umeå universitet/Institutionen för tillämpad fysik och elektronik

   Author : Simon Nilsson; [2019]
   Keywords : ;

   Abstract : Lime is a material with a wide range of applications including land improvement, water treatment as well as the paper-, steel-, and cement industry. Annual worldwide production was estimated at 350 Mt/year for 2016 and 2017 and the production is responsible for a large contribution of the greenhouse gas CO2 to the atmosphere, contributing to global warming.
