  2. 21. The inter- and intramolecular selectivity of the carbonate radical anion in its reactions with lignin and carbohydrates

    Author : Magnus Carlsson; KTH; []
    Keywords : ;

    Abstract : In the present thesis, the effects of the carbonate radicalanion on lignin and cellulose were investigated.Kinetic measurements by pulse -radiolysis were performed tostudy the reactions of simple lignin and cellulose models withthe carbonate radical anion. READ MORE

  4. 22. Mechanisms of formation and protection against oxidative DNA damage in vitro and in vivo

    Author : Peter Svoboda; Ralf Morgenstern; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physical Biology; fysikalisk biologi;

    Abstract : Oxidative DNA damage has been linked to cancer and aging as well as other diseases. The aim of this thesis was to study the mechanisms for DNA damage generated in cells or in vitro systems by ionizing radiation or transition metals like iron ions. READ MORE

  5. 23. Oxidative stress-related damage of retinal pigment epithelial cells : possible protective properties of autophagocytosed iron-binding proteins

    Author : Markus Karlsson; Christina Frennesson; Sven Erik Nilsson; Tino Kurz; Ulf Brunk; Anders Kvanta; Linköpings universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Oxidative stress is a major pathogenic factor in the development of age-related macular degeneration (AMD), which is the most common cause of severe central visual impairment in the elderly population in the western world.It is believed that the degenerative process starts in the retinal pigment epithelium (RPE).

  6. 24. Combustion Characteristics of a Swirl Dry Low Emission Burner Concept for Gas Turbine Application : Experiments and Simulations

    Author : Atanu Kundu; Kraftverksteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Gas Trubine Combustion; Partially Premixed flame; Flame stabilization; Swirl Flow; Emission; Experiments; Combustor; CFD; PLIF; PIV; Chemiluminescence;

    Abstract : In the current global energy scenario, gas turbine can provide delicate balance between the booming worlds energy requirement and a pollutant free sustainable society. Cleaner combustion of fuel (particular natural gas), efficient, reliable, low maintenance and cost effective operation of gas turbine attracted scientific community to push the limit further (high efficiency and zero emission gas turbine).

  7. 25. Laser Diagnostics in Reacting Flows

    Author : Panagiota Stamatoglou; Förbränningsfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; planar laser-induced fluorescence PLIF ; gliding arc GA discharge; Plasma Discharges; Turbulence; Combustion Engines; Spectroscopy; high-speed camera HSC ; Burst System; OH-LIF; optical parametric oscillator OPO ; Fysicumarkivet A:2023:Stamatoglou;

    Abstract : Burst-mode laser systems have widely been employed in diagnostics for both reactive and non-reactive flows. Unlike the continuous pulse lasers, burst-mode lasers generate pulses in bursts lasting up to 100 ms, capable to deliver high energies up to Joules per pulse. READ MORE
