Air and soil pollution from mining activities has been considered as a critical issue to the health of living organisms. However, few efforts have been made in distinguishing the main pathway of organism genetic damage by heavy metals related to mining activities. Therefore, we investigated the genetic damage of Leymus chinensis leaf cells, the air particulate matter (PM) contents, and concentr...
estimation of weed damage threshold is essensial in site-specific weed control programs. this experiment was conducted to determine the spatial distribution of weeds damage threshold in two wheat feilds. data related to weed biomass and crop yield were collected from sampling at 120 and 135 points of the first and second fields respectively based on a 4×4 m grid at research field of agricultura...
Fractal derivatives characterize the accelerated creep phase of process. In this study, based on fractal order theory, integer-order are defined from spatio-temporal self-similarity phenomenon dynamic process using scale change method, and viscoplastic model is improved to establish a new instantonal with damage describe complete anthracite. The effects variables initial were investigated by pe...
