  2. 1. Nutritional Properties of Liquid Oats as Affected by Processing and Storage

    Author : Huanmei Zhang; Tillämpad biokemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Biotechnology; Antioxidants; Avenanthramides; Biological value; Iron absorption; Fatty acids; Processing; Minerals; Vitamins; Storage; Stability; Nutritional properties; Oats; Beverage; Bioteknik;

    Abstract : The cholesterol-lowering effects of oats have led to an increasing interest in them on the food market. Liquid oats has emerged as a new way of consuming oats and has become a commercial product. READ MORE

  4. 2. Modeling of post-combustion carbon capture in power plants and process industries - partial capture and load following conditions

    Author : Stefanìa Òsk Gardarsdòttir; Chalmers University of Technology; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Post-combustion; MEA; ammonia; dynamic modelling; chemical absorption; industrial sources;

    Abstract : Carbon capture and storage (CCS) is recognized as a potent technology for the mitigation of global warming, since it can significantly reduce CO2 emission from large point source emitters. Post-combustion CO2 capture using chemical absorption is a versatile end-of-pipe technology that can be implemented at all point sources of CO2, such as a power production facility or industrial plant.

  5. 3. Formation and Transformation of Atmospheric Brown Carbon (BrC)

    Author : Kalyan Mitra; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Keywords : brown carbon BrC ; primary organic aerosol POA ; secondary organic aerosol SOA ; BrC bleaching; BrC browning; Toluene photo-oxidation; NOx; Ammonia; NH3; acidity effects; light absorption;

    Abstract : Atmospheric brown carbon (BrC) aerosol absorbs light in the UV-Vis spectrum and has poorly constrained but potentially large climate forcing impacts. Most current climate models lack detailed chemistry and interlinked properties of atmospheric BrC, that induce large uncertainties in radiative forcing predictions. READ MORE

  6. 4. Optical Frequency Comb Fourier Transform Spectroscopy

    Author : Alexandra C. Johansson; Aleksandra Foltynowicz; Ove Axner; Jürgen Röpcke; Umeå universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Optical frequency comb spectroscopy; Fourier transform; molecular absorption dispersion; fysik; Physics;

    Abstract : Fourier transform spectroscopy (FTS) based on optical frequency combs is an excellent spectroscopic tool as it provides broadband molecular spectra with high spectral resolution and an absolutely calibrated frequency scale. Moreover, the equidistant comb mode structure enables efficient coupling of the comb to enhancement cavities, yielding high detection sensitivity. READ MORE

  7. 5. Dicke narrowing and speed-dependent effects in dispersion signals : Influence on assessment of concentration and spectral parameters by noise-immune cavity-enhanced optical heterodyne molecular spectrometry

    Author : Junyang Wang; Ove Axner; Livio Gianfrani; Umeå universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Dicke narrowing; Speed-dependent effects; Dispersion signals; Noise-immune cavity-enhanced optical heterodyne molecular spectrometry NICE-OHMS ; accuracy;

    Abstract : Laser spectroscopic techniques have, during the last decades, demonstrated an extraordinary capability for sensitive detection of molecular constituents in gas phase. Since spectra from such techniques constitute unique and characteristic signatures for each type of species, these techniques enable investigations of molecular structures as well as detection of the presence of species in a gas mixture.
