    The Implication of the Helium-to-proton Flux Ratio in Galactic Cosmic Rays by Xiaojian Song, Xi Luo

    Published 2023-01-01
    “…The measurement of daily proton and helium fluxes by AMS-02 shows that the helium-to-proton flux ratio (He/H) is negatively correlated with the solar activity at rigidity 1.7–7 GV. …”

    Helium as a Carrier Gas in Humidification Dehumidification Desalination Systems by Narayan, G. Prakash, Zubair, Syed M., McGovern, Ronan Killian, Lienhard, John H

    Published 2016
    “…In this manuscript, we demonstrate that changing the carrier gas from air to helium a potential solution to this problem. In addition, the energy performance of a brine heated HDH system using helium relative to those using air is analysed in detail through well established on-design models for the components in the system.…”
