    Mining Failure Response Characteristics of Stope Floor: A Case of Renlou Coal Mine by Jucai Chang, Dong Li, Kai He

    Published 2020-01-01
    “…The results of on-site monitoring indicate that the mining effect of the working face is greater than that of the tectonic stress. With the advance of the working face, the deformation of the shallow area (0–8 m) first increases gradually, then increases rapidly, and finally increases gradually again; the middle area (8–19 m) experiences three stages, from a gentle increase to temporary stability and then a rapid increase; the deep area (19–29 m) undergoes three stages, from being stable to increasing and then being stable again. …”

    Faecalibacterium prausnitzii: A Next-Generation Probiotic in Gut Disease Improvement by Xiaoya He, Shuyang Zhao, Yan Li

    Published 2021-01-01
    “…It has been widely demonstrated that dysbiosis, which means the alternations of the gut microbial structure, is closely associated with development of intestinal chronic inflammation-related diseases such as inflammatory bowel disease (IBD), and even infectious diseases including bacterial and viral infection. Thus, for reshaping ecological balance, a growing body of the literatures have proposed numerous strategies to modulate the structure of the gut microbiota, which provide more revelation for amelioration of these inflammation or infection-related diseases. …”
