  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

    Master-uppsats, SLU/Dept. of Soil and Environment

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

    Sammanfattning : 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. LÄS MER

  3. 2. Gas Chromatographic Method Development for Analysis of Samples from a Carbon Capture Pilot Plant

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :David Wedin; [2024]
    Nyckelord :Carbon Capture and Storage; CCS; AMP DMSO; Gas Chromatography; amine absorption; analysis method development; Chemical Engineering; Chemistry;

    Sammanfattning : In response to the escalating threat of climate change, carbon capture and storage have gained increasing attention as an important component in mitigating the global carbon dioxide emissions. Substantial research efforts have focused on enhancing the energy efficiency and availability of these technologies. LÄS MER

  4. 3. Kontinuerlig rötning med hydrokol för högre biogasutbyte

    Master-uppsats, Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Författare :Annette Kariis; [2023]
    Nyckelord :Biogas; Continuous anaerobic digestion; Hydrochar; Hydrothermal Carbonisation; Life-cycle costing; Biogas; kontinuerlig anaerob rötning; Hydrokol; Hydrotermisk karbonisering; Livscykelkostnad;

    Sammanfattning : Befolkningsökningen och därmed efterfrågan på energikällor som tillhandahålls från fossila bränslen leder till allvarliga miljöproblem på grund av utsläpp av växthusgaser. En annan utmaning är att effektivt hantera organisk avfall som till exempel matavfall som genereras världen över. LÄS MER

  5. 4. Techno-economic Assessment of Carbon Capture from Low Concentration Streams

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Prithvi Kiran Joshi; [2023]
    Nyckelord :Carbon capture; industrial emissions; low concentration; MEA; Benfield; absorption; Immobilised Amine; adsorption; Kolavskiljning; industriella utsläpp; låg koncentration; MEA; Benfield; Absorption; Immobiliserad amin; Adsorption vi;

    Sammanfattning : Investments in carbon capture from industrial emissions have been on the rise in recent years, having reached over $200 million in 2021 as compared to 2015’s $13 million. The Paris Agreement, signed by 196 parties globally in 2015, is purported to be the primary driver for this, with its ambitious goal of limiting global surface temperature rise to 1. LÄS MER

  7. 5. An efficient deep reinforcement learning approach to the energy management for a parallel hybrid electric vehicle

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Mingwei Liu; [2023]
    Nyckelord :HEV; EMS; Deep Reinforcement Learning; Learning Efficiency; Fuel Efficiency; HEV; EMS; Djup Förstärkningsinlärning; Inlärningseffektivitet; Bränsleeffektivitet;

    Sammanfattning : In contemporary world, the global energy crisis and raise of greenhouse gas concentration in atmosphere necessitate the energy conservation and emission reduction. Hybrid electric vehicles (HEVs) can achieve great promise in reducing fuel consumption and greenhouse gas emissions by appropriate energy management strategies (EMSs). LÄS MER
