  1. 1. Conjugate Heat Transfer Analysis of HPGP Thruster

    Master-uppsats, Luleå tekniska universitet/Rymdteknik

    Författare :Lisa Svensson; [2024]
    Nyckelord :aerospace; HPGP; ECAPS; ANSYS; conjugate heat transfer; thruster; space;

    Sammanfattning : This master's thesis was conducted in collaboration with ECAPS, where a conjugate heat transfer analysis on their High Performance Green Propulsion (HPGP) 22N thruster was done. ECAPS is a Swedish propulsion company specializing in green propulsion. They develop thrusters for spacecraft orbit and attitude control, utilizing the propellant LMP-103S. LÄS MER

  3. 2. 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

  4. 3. Development of a Neutron Activation Analysis station at the Lund Ion Beam Analysis Facility

    Kandidat-uppsats, Lunds universitet/Kärnfysik; Lunds universitet/Fysiska institutionen

    Författare :Josephine Lindsey-Clark; [2021]
    Nyckelord :Neutron Activation Analysis; NAA; European Spallation Source; ESS; Lund Ion Beam Analysis Facility; LIBAF; Gamma-Ray Spectra; Physics and Astronomy;

    Sammanfattning : This report outlines the first stages of the development of the Neutron Activation Analysis station at the Lund Ion Beam Analysis Facility in the Division of Nuclear Physics, Lund University. The motivation for this project is to use the Neutron Activation Analysis detection technique for environmental monitoring around the European Spallation Source, soon to come into operation. LÄS MER

  5. 4. Groundwater denitrification by fluidized bioelectrochemical systems

    Master-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Lena Bonin; [2020]
    Nyckelord :Bioelectrochemistry; fluidized bed reactor; bioremediation; denitrification; groundwater; reduced graphene oxide;

    Sammanfattning : Groundwater (GW) accounting for most of the freshwater available around the World, finding sustainable techniques to depollute it is of crucial importance for safe drinking water supply. The extensive use of fertilizers in the agriculture, as well as other anthropogenic activities, are contributing to the excessive nitrate levels in some aquifers. LÄS MER

  7. 5. Investigation of possible non-additive behavior in the formation of secondary organic aerosol from a mixture of anthropogenic and biogenic VOC precursors

    Master-uppsats, Lunds universitet/Kärnfysik; Lunds universitet/Fysiska institutionen

    Författare :John Falk; [2014]
    Nyckelord :Volatile organic compounds; Biogenic; Anthropogenic; Secondary organic aerosol; Non-additive; Flow reactor; Scanning Mobility Particle Sizer; Earth and Environmental Sciences;

    Sammanfattning : Secondary organic aerosol (SOA) mass yields were tested for six combinations of two anthropogenic volatile organic compounds (AVOC); m-xylene & toluene, and three biogenic volatile organic compounds (BVOC); α-pinene, myrcene & isoprene. The purpose was to investigate any non-additive results in SOA formation from mixtures of AVOCs and BVOCs by comparing experimental yield with corresponding two-product model yields. LÄS MER
