2. 21. Development and Application of Rotational Coherent Anti-Stokes Raman Spectroscopy and Laser-induced Fluorescence for Combustion Diagnostics

   Author : Christian Brackmann; Förbränningsfysik; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Laser-induced Fluorescence; Formaldehyde; Biofuel; Laser technology; Laserteknik; Energy research; Energiforskning; Coherent Anti-Stokes Raman Spectroscopy; Combustion; Laser diagnostics; Fysicumarkivet A:2004:Brackmann;

   Abstract : The thesis concerns the development and application of two laser-based methods for combustion diagnostics: dual broadband rotational coherent anti-Stokes Raman spectroscopy (CARS) and laser-induced fluorescence (LIF). In efforts to increase the usefulness of the CARS technique, the applicability of a method involving a combination of the rotational CARS technique and the closely related vibrational CARS technique was investigated.

4. 22. Sensitivity-Enhanced Raman Spectroscopy and High-Speed Fluorescence for In Situ Gas-Phase Diagnostics

   Author : Haisol Kim; Förbränningsfysik; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Laser; Raman Spectroscopy; Laser-Induced Fluorescence; Combustion; Pyrolysis; Gasification; Gas turbine; Fysicumarkivet A:2022:Kim;

   Abstract : In this work, combustion and thermal decomposition processes were studied employing laser-based diagnostic techniques, and the techniques were improved and demonstrated to achieve enhanced detection sensitivity. Raman spectroscopy was employed to study flames under elevated and atmospheric pressures with various fuels, such as methane, hydrogen-enriched methane, DME, ethylene, and ammonia. READ MORE

6. 24. Patient-reported and medical outcomes in patients treated for diabetic macular edema : A real-world longitudinal study

   Author : Therese Granström; Janeth Leksell; Anna Forsberg; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Diabetes mellitus; Patient-reported outcomes; Retinopathy; Macular edema; Anti-VEGF treatment; Medicinsk vetenskap; Medical Science; Hälsa och välfärd;

   Abstract : Background Diabetes mellitus can lead to complications, when the complication affects the eyes it is called retinopathy. This can affect the macula and lead to severe loss of vision, diabetic macular edema (DME). This condition has traditionally been treated with laser. READ MORE

7. 25. Non-Spherical Particle Interaction in Duct and Jet Flow

   Author : Ammar Hazim; Matthias Mandø; Luleå tekniska universitet; []

   Abstract : Wood waste is the most popular biomass recourse for many nations. Burned wood can, direct or indirect, release one of the greenhouse gases, carbon dioxide. The process can still be seen as a renewable source of energy since replanting of the trees and crops are consuming nearly the same amount of carbon dioxide through photosynthesis. READ MORE
