Large deformation often occurs in the coal wall with weak interlayer, which affects the normal use of the roadway.Based on the research background of the track channel of 3308 working face in Dongtan Coal Mine, the large deformation characteristics of the side of the roadway with weak interlayer are analyzed by means of field measurement, numerical
In our article, Pudding Basin we focus on molecular mechanisms of immediately early genes expression.We discuss extracellular signals that are transduced into the nucleus through a variety of signaling mechanisms to elicit changes in patterns of immediately early genes expression, chiefly focusing on c-fos.Immediate early genes are involved in many
