  1. 6. Magnetic fields of cool stars from near-infrared spectropolarimetry

    Författare :Alexis Lavail; Oleg Kochukhov; Nikolai Piskunov; Gaitee Hussain; Jeff Valenti; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; stars: magnetic field; stars: pre-main-sequence; stars: late-type; techniques: spectroscopic; techniques: polarimetric; Astronomy; Astronomi;

    Sammanfattning : Magnetic fields rule many physical processes in and around stars throughout their lifetime. All cool stars possess a magnetic field, likely generated by dynamo processes. In order to properly understand the evolution of cool stars, we need to understand their magnetism. LÄS MER

  3. 7. Environmental Monitoring - using diode-laser-based spectroscopic techniques

    Författare :Gabriel Somesfalean; Atomfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Diode-laser spectroscopy; frequency-modulation spectroscopy; frequency conversion; diffraction; scattering; Electromagnetism; acoustics; akustik; optik; absorption spectroscopy; Elektromagnetism; optics; Fysicumarkivet A:2004:Somesfalean;

    Sammanfattning : Monitoring of environmental gases is necessary to understand the complex processes governing global warming and the impact of pollutant emissions related to human activity. Diode-laser-based spectroscopic techniques, being robust and affordable, have a great potential to become an industrially well-established technology for environmental sensing. LÄS MER

  4. 8. Characterising Weak Interactions in Solution. : An NMR Spectroscopic Approach

    Författare :Scott Wilcox; Máté Erdélyi; Chris Hunter; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Kemi med inriktning mot organisk kemi; Chemistry with specialization in Organic Chemistry;

    Sammanfattning : Detecting and characterising weak interactions in dilute solutions is challenging. This thesis focusses on the development of a new NMR spectroscopic strategy to do so, whilst also investigates a newly proposed type of weak interaction in solution with currently available NMR techniques.

  7. 10. Studies of Volcanic Plumes with Spectroscopic Remote Sensing Techniques

    Författare :Santiago Arellano; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Remote Sensing; FTIR; DOAS; Volcanic gas emissions;

    Sammanfattning : Volcanism is a widespread phenomenon on Earth and other planetary bodies. Terrestrial volcanoes are shallow manifestations of deep and complex mechanisms of heat and mass transport and play an important role in the formation and change of the atmosphere and the natural landscape.
