  2. 1. Geant4 Monte Carlo Simulations of the International Space Station Radiation Environment

    Author : Tore Ersmark; Bengt Lund-Jensen; Lembit Sihver; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Space physics; Rymdfysik;

    Abstract : A detailed characterization of the proton and neutron induced radiation environment onboard Columbus and the International Space Station (ISS) has been carried out using the Geant4 Monte Carlo particle transport toolkit. Dose and dose equivalent rates, as well as penetrating particle spectra corresponding to incident trapped protons, GCR protons, SPE protons and cosmic ray albedo neutrons are presented. READ MORE

  4. 2. Analysis of the Radiation Environment on Board the International Space Station Using Data from the SilEye-3/Alteino Experiment

    Author : Oscar Larsson; Bengt Lund-Jensen; Robert Seiringer; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Space Radiation; ISS; Alteino; Geant4;

    Abstract : This thesis presents an analysis of the radiation environment on board the Russian section of the International Space Station (ISS) using data from the SilEye-3/Alteino experiment. As part of the analysis the efficiency and response of the SilEye-3/Alteino detector was studied. READ MORE

  5. 3. Activities in space - appropriation or use?

    Author : Katrin Nyman Metcalf; Uppsala universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Law; rättsvetenskap; juridik; LAW JURISPRUDENCE; RÄTTSVETENSKAP JURIDIK;

    Abstract : This Thesis is a work of public international law, more specifically of international space law. The Thesis deals with the question of whether different activities in outer space and on celestial bodies are permitted under the rules of freedom of use in the law of outer space or whether some activities amount to appropriation of space, which is banned.

  6. 4. Exhaled nitric oxide in extreme environments

    Author : Tryggve Hemmingsson; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Exhaled nitric oxide; hand-held instrument; electrochemical detector; microgravity; International Space Station; high altitude; hypobaric hypoxia; normobaric hypoxia; backdiffusion;

    Abstract : Exhaled nitric oxide (NO) is a useful marker for lower airway inflammation. Since NO was found to be a component of an exhaled breath in the early 1990´s, the Fractional Exhaled Nitric Oxide (FENO 50) measurement is now well accepted among clinicians as a complementary test in the management of asthma.

  7. 5. Cosmic clues from astrophysical particles

    Author : Francesca Capel; Christer Fuglesang; Michael Unger; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Fysik; Physics;

    Abstract : Ultra-high-energy cosmic rays (UHECRs) are charged particles that have been accelerated to extreme energies, such that they are effectively travelling at the speed of light. Interactions of these particles with the Earth’s atmosphere lead to the development of extensive showers of particles and radiation that can be measured with existing technology. READ MORE
