    Changements climatiques et risques naturels dans les Alpes by Benjamin Einhorn, Nicolas Eckert, Christophe Chaix, Ludovic Ravanel, Philip Deline, Marie Gardent, Vincent Boudières, Didier Richard, Jean-Marc Vengeon, Gérald Giraud, Philippe Schoeneich

    Published 2015-09-01
    “…We give a brief overview of new results achieved by research, cooperation and capitalisation projects in these thematic fields during the programme period 2007-2013, which are available on databases, thematic knowledge platforms and observatories developed by different scientific and technical operators in the larger framework of the European Alpine arc. We illustrate this renewed synthesis by published examples of hydro-gravitational hazard activity chronicles, along with climate patterns identified as “predictors”.…”

    Deoxidation of steel with calcium carbide. Influence of calcium carbide addition on steel contamination by non‑metallic inclusions by A. V. Shatovsky, O. M. Grudnitskiy, S. V. Konovalenko, I. A. Kovaleva, A. A. Kovalev, V. O. Morozov

    Published 2024-09-01
    “…In turn, the use of calcium carbide for deoxidation of the melt upon its release from the electric arc furnace into the ladle, instead of secondary aluminum ingots of grade AB87 according to GOST 295–98, helps to reduce the contamination of steel with non‑metallic inclusions.…”

    Complex Structure around a Circumstellar Disk Caused by Interchange Instability by Masahiro N. Machida, Shantanu Basu

    Published 2025-01-01
    “…During the main accretion phase, the interchange instability occurs recurrently, disturbing the circumstellar region and forming ring, arc, and cavity structures. These are consistent with recent high-resolution observations of circumstellar regions around young protostars. …”

    Hydrogen and hydrogen sulphide in volcanic gases: abundance, processes, and atmospheric fluxes by Aiuppa, Alessandro, Moussallam, Yves

    Published 2023-09-01
    “…The high H$_{2}$ concentrations (and low H$_{2}$S/SO$_{2}$ compositions, of ${\sim }$0.1 on average) in high-temperature (${>}$1000 °C) magmatic gases are overall consistent with those predicted thermodynamically assuming external redox buffering operated by the coexisting silicate melt, at oxygen fugacities ranging from ${\Delta }$FMQ $-$1 to 0 (non-arc volcanoes) to ${\Delta }$FMQ 0 to ${+}$2 (arc volcanoes) (where ${\Delta }$FMQ is oxygen fugacity expresses as a log unit difference relative to the Fayalite–Magnetite–Quartz oxygen fugacity buffer). …”

    Vibration Fatigue Life Prediction and Parameter Optimization of Roadheader Picks by He Yang, Li Xiaohuo, Xi Yabing

    Published 2024-05-01
    “…The results show that the longest life of the pick is located at the slope area, the second in the arc area, and the lowest in the cylinder area. The corner of the pick is defined as the optimization objective based on particle swarm optimization algorithm, the optimal corner value is obtained, and the life of the picks is increased by an order of magnitude. …”
