    Application of a Direct Stiffness Method to Wave Propagation in Multiphase Poroelastic Media (1997)

    Notes: Abstract In this paper, it is demonstrated how a direct stiffness method for wavepropagation in multilayered saturated poroelastic media, based on integraltransform techniques, can be modified to account for a small amount of gasin the pores. Unsaturated media with small gas fractions can be treatedusing Smeulders‘ extension of Biot‘s poroelastic theory. The effect of thepresence of gas bubbles on the fluid bulk modulus and the dispersioncharacteristics of a water-saturated sand of Mol is demonstrated. Thedirect stiffness method is illustrated with a numerical example wheretransient wave propagation in a dry, saturated and unsaturated halfspaceis considered.

    Free amino acid analysis of five microalgae (1998)
    Springer
    Journal of applied phycology 10 (1998), S. 131-134 
    Details
    ISSN: 1573-5176
    Keywords: Free amino acids ; HPLC ; microalgae ; Tetraselmis suecica ; Isochrysis galbana ; Thalassiosira sp. ; Skeletonema costatum ; Chaetoceros calcitrans ; cosmetology
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Abstract The HPLC separation of fluorescent o-phtaldialdehyde (OPA) derivatives has been applied to the assay of free amino acids from five microalgae commonly used in aquaculture: Tetraselmis suecica, Skeletonema costatum, Chaetoceros calcitrans, Thalassiosira sp. and Isochrysis galbana, as part an assessment of their potential use in cosmetic products. Thirteen free amino acids were analyzed using High Performance Liquid Chromatography. There were considerable differences between species. However, four amino acids were responsible for more than 60% total concentration in all species: ASP, GLU, ARG and TYR; the next most important (accounting for less than 30%) were: ALA, VAL, PHE and LYS.

    Absence of many-body mobility edges (2016)
    American Physical Society (APS)

    Publication Date: 2016-01-23
    Description: Author(s): Wojciech De Roeck, Francois Huveneers, Markus Müller, and Mauro Schiulaz Phenomenon of many-body localization violates one of the basic rules of statistical mechanics: It states that certain ‘localized’ macroscopic systems cannot act as a bath for themselves and hence do not relax to equilibrium. The authors of this paper find that, whenever a system is not localized at all thermodynamic parameters (particle density, energy density), then local fluctuations into the non-localized phase, dubbed bubbles, can slowly destroy localization globally. This result provides a rather strong restriction on the existence of many-body localized phases and runs contrary to the idea that there could be genuine localization transitions as a function of temperature.
