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. Investigating the potential correlations between metal and metalloid concentrations and soil color : A Minor Field Study on the island province of Marinduque, Philippines

   University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

   Author : Ivana Pia Saric Söderholm; Erik Readwin; [2023]
   Keywords : Marinduque; Metal and Metalloid; Nix Pro 2 Color Sensor; Philippines; Soil color; X-Ray Fluorescence XRF ; Filippinerna; Jordfärg; Marinduque; Metall och Metalloid; Nix Pro 2 Color Sensor; Röntgenfluorescens XRF ;

   Abstract : This study was carried out as a bachelor's thesis at KTH Royal Institute of Technology during the spring of 2023, investigating the correlation between the color with the concentration of various metal and metalloids (MMs) in the soil of Marinduque, The Philippines. With a history of mineral exploitation, notably copper and gold, the island has faced persistent environmental challenges, exemplified by the catastrophic waste spills in 1993 and 1996 that contaminated the Boac and Mogpog Rivers.

4. 3. Microstructure and Mechanical Investigation ofCarbides Particles Reinforced High AusteniticManganese Steel

   University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Author : Abderrahim Ait ouakrim; [2023]
   Keywords : Metal Matrix Composites MMCs ; Manganese steel; Carbides particles; Wear resistance;

   Abstract : The objective of this study was to produce a metal matrix composite (MMC). This compositematerial proves highly suitable for scenarios involving abrasive wear, owing to the exceptionalhardness of carbide particles, in conjunction with the remarkable ductility and capacity for workhardening found in Hadfield steel.

5. 4. 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

6. 5. Simulation and Experimental Based Hardenability Evaluation of Chromium Alloyed Powder Metal Steels

   University essay from KTH/Materialvetenskap

   Author : Atharva Kotasthane; [2023]
   Keywords : Hardenability; Martensite; Simulation Modelling; Microhardness; Microstructure; Härdbarhet; Martensit; Simuleringsmodellering; Mikrohårdhet; Mikrostruktur;

   Abstract : Powder metallurgy is a branch of metal forming technology where metal powders are used to manufacture parts and components. It is a flexible and economical technique for manufacturing complicated shapes. This present work focuses on press and sinter technology and forms a part of Höganäs’s efforts of modelling hardenability through quenching. READ MORE
