Spatial analysis of neural tube defects in a rural coal

Shanxi province in northern China has one of the highest reported prevalence rates of neural tube defects (NTDs) in the world. The current study selected Heshun the county with the highest rate of NTDs in Shanxi as a study area and tested whether residence in a coal mining area was a contributing factor. A NTD cluster was detected in an area within 6 km of the coal mines for almost every year

An experimental study on the correlation between the

We collected ten coal rock samples in three mines in the Heshun area of the Qingshui basin to study the characteristics of microfractures in coal beds and to understand the characteristics of P-wave and S-wave propagation in coal beds which include four coal rock samples from the Taiyuan Carboniferous formation and six from the Shanxi Permian
