1. 1. Impact of nitrogen availability and nitrogen structural composition on fungal enzymatic activity and growth : how nutrient availability governs response and development of three saprotrophic Basidiomycetes

   University essay from SLU/Dept. of Soil and Environment

   Author : Bella Strid; [2024]
   Keywords : nitrogen; tannins; condensed tannins; MnP; manganese peroxidase; peptidase; saprotrophic basidiomycetes;

   Abstract : Fungi excrete a wide variety of extracellular enzymes to scavenge for nutrients, such as the often scarce yet essential nutrient nitrogen. All fungi produce highly specialized hydrolytic enzymes, e.g. peptidases, that depolymerize organic molecules. READ MORE

3. 2. Machinability study on GCI brake discs - Effects of material variations and process behavior on tool life

   University essay from Lunds universitet/Industriell Produktion

   Author : Christian Jaunviksna; [2023]
   Keywords : Metal cutting Machinability Grey cast iron Tool wear Cutting data Hardness Microstructure Segmentation; Technology and Engineering;

   Abstract : Grey cast iron is one of the most used materials in the automotive industry. The material has a range of properties that makes it suitable for machining applications, but manufacturers still experience machinability problems. READ MORE

4. 3. Purification of Volatile Organic Compounds in Channeled Ventilation Pipes at the Sysav Water Treatment Plant for Hazardous Waste

   University essay from Lunds universitet/Kemiteknik (CI)

   Author : Erik Wiktorsson; [2022]
   Keywords : VOC; Zeolite; Catalytic combustion; Sysav; Chemical Engineering; Chemistry; Technology and Engineering;

   Abstract : Several channeled emissions at the Sysav water treatment plant for hazardous waste as of December 2021 exceed permitted levels of unknown volatile organic compounds (VOCs) stated in the European Parliament councils’ directives 2010/75/EU. A range of possible treatment methods are briefly discussed before zeolite adsorption, and thermal regeneration followed by catalytic combustion is decided to be the method of greatest feasibility and is the subject of further investigation.

5. 4. Nutrient dynamics in pak choi cultivation fertilized with biogas digestate : effects of non-nutrient digestate elements and amendment with mineral nutrients

   University essay from SLU/Department of Biosystems and Technology (from 130101)

   Author : Kristina Weimers; [2020]
   Keywords : Biogas digestate; pak choi; Brassica rapa; ssp. chinensis; ‘Joy Choi’; greenhouse; soilless production; peat-based growing media; biostimulants; nitrification; nutrient recovery efficiency; phosphorus; sulphur;

   Abstract : Anaerobic digestion in biogas plants produces renewable energy and a residue which is rich in plant nutrients. This residue is called digestate. Today, these digestates are mostly spread directly onto fields as manure. READ MORE

6. 5. Synthesis of thin films of the Olivines Fe2SiS4 and Mn2SiS4 by magnetron sputtering and annealing

   University essay from Uppsala universitet/Fasta tillståndets elektronik

   Author : Joakim Eriksson; [2017]
   Keywords : photovoltaic; solar cell; thin film; semiconductor; absorber; abundant; olivine; ternary metal chalcogenides; manganese silicon sulfide; Mn2SiS4; iron silicon sulfide; Fe2SiS4; reactive magnetron sputtering; sulfurization; annealing; composition gradient; combinatorial; SEM; EDS; XRD; oxidation;

   Abstract : The photovoltaic industry attracts a lot of interest from researchers worldwide due to active integration of the solar cells. The main idea here is to convert solar energy into electricity. One type of solar cell that shows potential in replacing today’s crystalline silicon cells is the thin film solar cell (TFSC). READ MORE
