Micro-topography has been proved to be beneficial for plant colonization in severe environments. There are numerous micro-topographies caused by erosion of gangue dumps the Northeast China, which can make difficult. To determine how these affect colonization, environment conditions, regeneration characteristics, vegetation characteristics different micro-topographies, such as bare slope, rill, ...

Limited information is currently available on how sediment transport affects rill flow resistance and the influence of hydraulic variables, as stream power, capacity for flows. In this paper, measurements variables (flow depth, channel slope, mean velocity, Reynolds number, Froude Darcy–Weisbach friction factor) carried out by Ban et al. (Measurement ephemeral gully velocities their model expre...

Previous studies have shown that the development of mam mary alveolar lesions (MALs) precedes the emergence of overt mammary tumors in high-breast-cancer strains of mice, such as Rill, that are infected with exogenous murine mammary tumor virus. We cultured MAL-containing whole mammary glands from 7-month-old nulliparous Rill mice for 8 days (Days 0 to 8) in a serum-free medium that contained i...
