    poum et cinéma: entre art et Révolution (1936-1937) by Cindy Coignard

    Published 2020-12-01
    “…In a context of civil war, we have to wonder about the choices which are made in the diffusion of films: which criteria come into play and how they made the selection in relation to the dissident Marxist ideology.…”

    Retention of locally injected human iPS cell-derived cardiomyocytes into the myocardium using hydrolyzed gelatin by Jun Iida, Kazuki Kotani, Kozue Murata, Keisuke Hakamada, Wusiman Maihemuti, Yoshinobu Mandai, Yosuke Hiraoka, Kenji Minatoya, Hidetoshi Masumoto

    Published 2025-02-01
    “…Using both ex vivo and in vivo rat models, we investigated how varying HG concentrations affect the retention of solution and diffusion within the myocardium. In ex vivo static rat hearts, 10% HG minimized leakage but allowed significant diffusion. …”

    Verification of Interaction Between Cl<sup>−</sup> Erosion and Carbonation in Marine Concrete by Maohua Zhang, Lin Du, Ronghua Xu

    Published 2025-01-01
    “…This study reveals that (1) Cl<sup>−</sup> erosion hinders concrete carbonation as NaCl crystals and Friedel’s salt in the pores limit CO<sub>2</sub> penetration, with this effect intensifying at higher artificial seawater concentrations; (2) carbonation has a dual impact on Cl<sup>−</sup> erosion: in fully carbonated areas, carbonation products block pores and restrict Cl<sup>−</sup> diffusion, while at the interface between carbonated and non-carbonated zones, carbonation depletes Ca(OH)<sub>2</sub>, reducing Cl<sup>−</sup> binding capacity, increasing free Cl<sup>−</sup> content, and promoting Cl<sup>−</sup> diffusion.…”

    Numerical modeling of wave-induced liquefaction around a gravity-based structure by V. S. Ozgur Kirca, V. S. Ozgur Kirca, Mert Angin, B. Mutlu Sumer

    Published 2025-02-01
    “…The model employs a two-step procedure: First, the stresses in the soil domain are determined via solving Biot equations, and subsequently the generation and diffusion of accumulated pore pressure in the soil is simulated by means of a pressure diffusion equation with a source term. …”
