  1. 1. Models for estimating radiation dose and LAR from radioactive fallout: extended dose algorithms for the computational tool LARCalc

    Master-uppsats,

    Författare :Jonathan Sundström; [2022-09-09]
    Nyckelord :Medical physics; Nuclear power plant; Radiation dose; Effective dose; Lifetime attributable risk; LAR; Fallout; Inhalation; Strontium-90; Iodine-131; Cloudshine;

    Sammanfattning : Today, emergency preparedness is needed against both nuclear reactor accidents and nuclear weapons fallout. Both scenarios can lead to exposure of ionizing radiation. Upon exposure, radionuclides will incur a radiation dose both internally and externally. LÄS MER

    Nyckelord :Thermal energy storage TES ; Thermochemical heat storage TCS ; SrCl2-NH3; Absorption; Desorption; Monoammine; Octaammine; Performance evaluation.; Termisk energilagring TES ; Termokemisk energilagring TCS ; SrCl2-NH3; Absorption; Desorption; Monoammin; Oktaammin; Utvärdering av prestanda.;

    Sammanfattning : This thesis is part of a joint thermochemical heat storage (TCS) research project named Neutrons for Heat Storage (NHS), involving three Nordic research institutes. The project isfunded by Nordforsk and KTH Royal Institute of Technology for the project partner KTH. LÄS MER

  4. 3. Laser cooling, state initialization and laser manipulation of a trapped ion

    Kandidat-uppsats, Stockholms universitet/Fysikum

    Författare :Julius Andersson; [2021]
    Nyckelord :Ion trap; Quantum computer;

    Sammanfattning : One way of realizing a quantum computer is to use an ion trap. The research group Trapped Ion Quantum Technologies at Stockholm university were operating an ion trap with strontium ions. To increase the coherence time they installed a magnetic field shielding. Therefore the experimental setup had to be partially rebuilt. LÄS MER

  5. 4. Review and Design Adaptations of a SrCl2-NH3 bench-scale Thermochemical Heat Storage system

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

    Författare :Hjörtur Brynjarsson; [2021]
    Nyckelord :Thermochemical heat storage TCS ; SrCl2-NH3; system design; kinetics; absorption; desorption; octaammine; diammine; monoammine; pressure management; commissioning; Termokemisk värmelagring TCS ; SrCl2-NH3; systemdesign; kinetik; absorption; desorption; oktaammin; diammin; monoammin; tryckhantering; driftsättning;

    Sammanfattning : Thermochemical heat storage (TCS) is a thermal energy storage (TES) technology used to store thermal energy for later use. TCS can provide heating or cooling services from intermittently available thermal energy, often low grade waste heat. LÄS MER

  7. 5. Chemical analysis of hazardous substances in permanent tattoo inks available on the market

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

    Författare :Anna Bevin; An Na Lay; Daniel Ullmark; Jessika Hagman; [2020]
    Nyckelord :Tattoo inks; tattoos; metals; pigments; skin; matrix assisted laser desorption ionization time of flight mass spectrometry; inductively coupled plasma mass spectrometry; mass spectrometry; allergens; dyes;

    Sammanfattning : As permanent tattoos are becoming more popular and common, an increased number of allergic reactions to tattoos is reported. The purpose of this project was to analyze tattoo inks for hazardous substances, and whether they comply to current Swedish and European legislative requirements. LÄS MER
